Abstract:
This paper presents a novel theoretical study of the geometry and derived kinematics of a typical multicable suspension system as encountered on a rubber tyred gantry (RTG) crane. Machines of this sort are used extensively in the international container handling business but, to date, little has been known about the precise motions of cable suspended spreaders other than general intuitions about fore—aft, lateral and rotational oscillations. Such motions are initiated by driver-controlled motion of the gantry itself (by torques applied to the driving wheels) and by across-the-vehicle motions of the trolley from which the spreader and container payload are suspended. The work reported here shows the complete derivation for spreader coordinates, relative to the trolley, for any translational and/or rotational displacement. Conventional geometrical and trigonometrical principles are used throughout the development. This research forms an integral part of a larger programme of work to propose strategies for accurate spreader motion control based on non-linear dynamic models.

Abstract:
For liquid transfer system in three-dimensional space, the use of multijoint robot arm provides much flexibility. To realize quick point-to-point motion with minimal sloshing in such system, we propose an integrated framework of trajectory planning and sloshing suppression. The robot motion is decomposed into translational motion of the robot wrist and rotational motion of the robot hand to ensure the upright orientation of the liquid container. The trajectory planning for the translational motion is based on cubic spline optimization with free via points that produces smooth trajectory in joint space while it still allows obstacle avoidance in task space. Input shaping technique is applied in the task space to suppress the motion induced sloshing, which is modeled as spherical pendulum with moving support. It has been found through simulations and experiments that the proposed approach is effective in generating quick motion with low amount of sloshing.

Abstract:
A geometric model of a new method of delivering fire-extinguishing substances to a fire zone located at a considerable distance was offered. The idea of delivery is based on the mechanical action of throwing. To this end, a substance (e.g. extinguishing powder) is loaded in a hard shell made as a special container. After delivery by means of a launcher to a fire zone, the container has to release the substance which will promote fire extinguishing. The known method of remote delivery of extinguishing substances uses a pneumatic gun with a cylindrical container. During delivery, the cylinder must rotate around its axis to ensure flight stability. The cylinder is rotated by a special turbine when passing through the gun barrel. There are difficulties in regulating the distribution of compressed air flows during the turbine operation. In addition, the tightness of the pneumatic part of the gun should be monitored. The new delivery method uses a container in a form of two spaced loads similar to a sports dumbbell. The dumbbell motion is initiated by simultaneous action of explosion-generated pulses directed at each of its loads in a pre-calculated manner. This results in the rotational motion of the container. To describe the dynamics of the dumbbell motion, a Lagrangian was defined and a system of Lagrange differential equations of the second kind was set up and solved. Examples of modeling trajectories of the centers of masses of the dumbbell loads taking into account air resistance were given. The proposed method is planned to be a basis of a new fire extinguishing technology. This is evidenced by the new scheme of launching the dumbbell by means of explosion-generated pulses of charges of two pyro cartridges. The obtained results make it possible to estimate magnitudes of explosion-generated pulses necessary for throwing and corresponding distances of the dumbbell delivery

Abstract. With the prospects of seismic equipment being able to measure rotational ground motions in a wide frequency and amplitude range in the near future, we engage in the question of how this type of ground motion observation can be used to solve the seismic source inverse problem. In this paper, we focus on the question of whether finite-source inversion can benefit from additional observations of rotational motion. Keeping the overall number of traces constant, we compare observations from a surface seismic network with 44 three-component translational sensors (classic seismometers) with those obtained with 22 six-component sensors (with additional three-component rotational motions). Synthetic seismograms are calculated for known finite-source properties. The corresponding inverse problem is posed in a probabilistic way using the Shannon information content to measure how the observations constrain the seismic source properties. We minimize the influence of the source receiver geometry around the fault by statistically analyzing six-component inversions with a random distribution of receivers. Since our previous results are achieved with a regular spacing of the receivers, we try to answer the question of whether the results are dependent on the spatial distribution of the receivers. The results show that with the six-component subnetworks, kinematic source inversions for source properties (such as rupture velocity, rise time, and slip amplitudes) are not only equally successful (even that would be beneficial because of the substantially reduced logistics installing half the sensors) but also statistically inversions for some source properties are almost always improved. This can be attributed to the fact that the (in particular vertical) gradient information is contained in the additional motion components. We compare these effects for strike-slip and normal-faulting type sources and confirm that the increase in inversion quality for kinematic source parameters is even higher for the normal fault. This indicates that the inversion benefits from the additional information provided by the horizontal rotation rates, i.e., information about the vertical displacement gradient.

Abstract:
This study presents a comprehensive analysis of the hydrodynamic behavior of a containership under varying wave conditions using the Boundary Element Method (BEM). The hydrodynamic pressure distribution, as derived from BEM simulations, highlights critical pressure zones on the vessel’s hull, with maximum pressures reaching approximately 160 N/mm² near the bow. These high-pressure regions, caused by direct wave impacts, emphasize the structural vulnerability to fatigue, underscoring the need for reinforced designs in areas subjected to repeated loading. Additionally, the pressure mapping reveals patterns that align with expected wave-induced behaviors, validating the effectiveness of the BEM in capturing critical load distributions. The analysis also investigates wave excitation forces and diffraction/Froude-Krylov forces across six motion modes (surge, sway, heave, roll, pitch, and yaw). Translational modes exhibit peak forces of up to 8000 N at low wave frequencies (~0.1 Hz), while rotational modes encounter forces as high as 10^8 N, particularly in roll and pitch. These findings highlight the influence of wave characteristics, such as frequency and angle, on vessel stability and structural stress. The results provide valuable insights for vessel design and operational planning, advocating for enhanced stabilization systems, optimized structural reinforcements, and improved cargo placement strategies to ensure safety, performance, and longevity under various sea conditions.

Abstract:
Abstract The dynamics of a phase inclusion in a coaxial liquid layer divided with a radial partition is studied experimentally. The working volume of the container is filled with a viscous liquid, inside which an air bubble, immiscible with the main phase, is injected. This inclusion has a lower density than the surrounding liquid does. The container performs rotational oscillations as a whole with the zero average rotation. Such a motion brings to the generation of a harmonically oscillating azimuthal shear flow, which, as a consequence, excites the oscillations of the phase inclusion. During the bubble’s oscillations, the displacement of its geometric center follows the sinusoidal law. On the background of such a motion a periodic deformation of the bubble is observed, i.e. the phase boundary starts oscillating. A new and surprising result of the experiments is found, when the light bubble sinks and takes a quasi-steady position near the inner wall of the layer.

Abstract:
Higher operational efficiency of container transportation can be achieved by putting into operation hopper containers. The special feature of a container is its inclined end and sidewalls, which makes it possible to self-discharge bulk freight through the discharging hatches forming the floor. The vertical loading of a hopper container placed on the long-base flat car was determined with the mathematical modelling. The mathematical model described the translational movement of a flat car in the vertical plane, i.e. bouncing oscillations. The flat car for the calculation consisted of three bodies: bearing structure loaded with four containers and two 18-100 bogies. The containers were considered as attached masses that completely repeated the movement pattern of the bearing structure of the flat car in the vertical plane. The mathematical model also included the elastic characteristics of the track. The calculation was made for the containers placed on a long-base 13-7024 flat car. The mathematical model was solved with the Runge-Kutta method in MathCad. The initial conditions were equal to zero. It was found that the maximum acceleration in the mass center of the bearing structure of a flat car loaded with hopper containers was 1.28 m/s2, which did not exceed the allowable values. The vertical dynamic coefficient was 0.13. The motion of the flat car was estimated as excellent.The results of the research will be of value for those who are dealing with development of advanced container structures with better operational efficiency for container transportation.Key words: transport mechanics, hopper container, dynamic loading, dynamic characteristics, container transportation.

Abstract:
In recent years, sensors have been moving towards the era of intelligence, miniaturization and low power consumption, but the power-supply problem has always been a key issue restricting the popularization and development of machine-mounted sensors on the rotating machinery. Herein, we develop a ring-type triboelectric nanogenerator (R-TENG) that functions as a sustainable power source as well as a self-powered rotational speed sensor for rotating machinery. The R-TENG adopts a freestanding mode and consists of a ring-type container unit, an end cover and polytetrafluoroethylene (PTFE) cylinders. In this study, the influence of the number of cylinders, the PTFE cylinder’s diameter and the rotational speed on the electrical output are systematically examined, and the motion law of the PTFE cylinders in the container is revealed by the experimental results and verified by kinetic simulation. At a rotational speed of 400 rpm, the output voltage, current and transferred charge of the designed R-TENG reached 138 V, 115 nC and 2.03 μA, respectively. This study provides an attractive power supply strategy for machine-mounted sensors of the rotating machinery, and the rotational speed measurement test also suggests the potential application of the R-TENG as a self-powered rotational speed sensor.

Abstract:
The work is devoted to the method of delivering a fire extinguishing agent into a distant fire zone. In a known method, a substance (for example, a fire extinguishing powder) is placed in a solid shell - a cylindrical container. After delivery to the location of the fire, the container should collapse and free up the substance that will be assisted on fire extinguishing. A pneumatic gun is used to deliver a cylindrical container. In the process of delivery, the cylinder should rotate around its axis to ensure the stability of the movement. At the same time, during the "shot", the difficulty of regulating the distribution of compressed air flows in the gun dulk to achieve the required speed of rotation of the cylinder is arisen.
 In a new delivery method, it is proposed to use a container consisting of two spherical containers connected by a rod (like dumbbells). Traditional motion modeling Dumbbells is based on the preparation and solution of the system of differential equations of Lagrange of the second kind. To do this, choose the functions of generalized coordinates and use Lagrangian to describe the rotational and progressive movement of dumbbells in the earth's field. This allows you to obtain approximate functional dependences, as well as dependencies of derivatives for each of the functions of generalized coordinates. As a result, you can depict charts of phase trajectories of the generalized coordinates. The dependence on time for the functions of generalized coordinates allow you to simulate the outer ballistics dumbbells - i.e. Create a computer animation of its rotational and progressive movement.
 In contrast to the traditional approach in this paper, an engineering method of geometric modeling of the external ballistics of the movement of dumbbells is proposed. Those. The method of modeling the rotational and progressive movement dumbbells, which is based on geometric representations. We assume that the auxiliary circle is rigidly fixed on the dumbbells, the center of which coincides with the center of mass dumbbells. Let the circle "quoted" along the ballistic trajectory of the Mass Dumbbell Center. Then the trajectories of the point mass of cargo dumbbells will give an approximate view of the rotational and progressive movement of dumbbells into spacious within the vertical plane.

Abstract:
The controlled translocation of submolecular units is seen as an important requirement for the future development of “machines” which function through mechanical motion at the molecular level. Mechanically-interlocked molecules, <i>i.e.</i> catenanes and rotaxanes, are ideal candidates for application as components for molecular devices due to the inherent restrictions in the degrees of freedom presented in their architectures. Hydrogen bond-directed assembly offers powerful strategies for the synthesis of such structures on a scale where practical applications become a realistic area for study. This Thesis focuses on (i) the use of hydrogen bonding interactions in the synthesis of structurally different fumaramide template-containing [2]rotaxanes, (ii) the control of the rotational and translational motion in stimuli-responsive [2]rotaxanes and (iii) the control of a physical property, such as elliptical polarization, in a stimuli-responsive two-station [2]rotaxane. The stimuli required to promote the submolecular motion are light and heat.

Abstract:
Low-frequency Earth-horizontal translational and rotational oscillations can cause motion sickness in transport. Previous studies have found that motion sickness depends on the frequency, magnitude, direction and duration of the motion, however, knowledge of the mechanisms of motion sickness is far from complete. The concept of sensory conflict – that motion sickness arises because of a conflict between sensed and expected sensory information is central to theories of motion sickness, but little is known about how the physical characteristics of motion influence sensed and expected sensory signals. The aim of this research was to advance understanding of the effect on motion sickness of factors which may influence sensed and expected vestibular signals during exposure to low-frequency translational and/or rotational oscillation. The first experiment investigated whether motion sickness depends on the phase between combined lateral acceleration and roll oscillation at 0.2 Hz. The roll oscillation had one of four phases relative to the lateral acceleration: 0° delay, 14.5° delay, 29° delay, and 29° advance. Sickness decreased as the delay in the roll motion increased; less sickness occurred with a phase advance than a phase delay, suggesting that motion sickness cannot be predicted from the acceleration in the plane of the seat. The second experiment investigated how motion sickness varies between four 60-minute exposures of 0.1 Hz combined lateral and roll oscillation which involved different combinations of a high and low magnitude motion: LLLL, HHHH, LHHL and HLHL. The high magnitude motion produced greater sickness than the low magnitude motion. For the two variable motion conditions, there was no significant difference in accumulated illness ratings when the motion sickness dose values were the same. In the third experiment, 0.2 Hz roll and pitch oscillation were studied at three displacements: ±1.83° ±3.66° or ±7.32°. A trend for motion sickness to increase with increasing displacement was observed; similar sickness was caused by roll and pitch oscillation at each magnitude. In the fourth experiment, subject head displacement was measured during 0.2 Hz fore-and-aft oscillation with and without a backrest at three magnitudes: 0.22, 0.44, and 0.89 ms-2 r.m.s. Illness increased systematically with increasing magnitude of oscillation with a backrest, but less systematically without a backrest, suggesting an interaction between the effect of motion magnitude and the influence of a backrest. There were no significant differences in illness with or without a backrest at any of the magnitudes studied. Between subjects, there was little evidence to suggest that greater fore-and-aft and pitch displacement of the head was associated with an increase in motion sickness. Combined findings from the third and fourth experiments suggest that 0.2 Hz fore-and-aft oscillation causes greater sickness than 0.2 Hz pitch oscillation at each of the three magnitudes studied (assuming that pitch motion can be represented by the gravitational component, gSinθ). A motion sickness model is proposed showing how the factors investigated in this thesis affect the sensed and expected semi-circular canal signals which are assumed to be involved in the causation of motion sickness. The model predicts how sensed and expected signals vary according to the phase between motions, the magnitude, direction and duration of motion, the type of motion and the postural support given to subjects. Explanations of how the model predicts motion sickness based on the findings of this study and previous studies are discussed.

Abstract:
Human vision recognizes the direction of a human, an animal, and objects in translational motion, even when they are displayed in a still position on a screen as filmed by a panning camera and with the background erased. Because there is no clue to relative motion between the object and the background, the recognition relies on a facing direction and/or movements of its internal parts like limbs. Such high-level object-based motion representation is capable of affecting lower-level motion perception. An ambiguous motion pattern is inserted to the screen behind the translating object. Then the pattern appears moving in a direction opposite to that which the object implies. This is called the backscroll illusion, and psychophysical studies were conducted to investigate phenomenal aspects with the hypothesis that the illusion reflects a strategy the visual system adopts in everyday circumstances. The backscroll illusion convincingly demonstrates that natural images contain visual illusions.

This chapter considers the quantum mechanics of translation and vibration. Both types of motion can be solved in certain cases, and both are important not only in their own right but also because they form a basis for the description of more complicated types of motion. It mentions translational motion, which has the advantage of introducing in a simple way many of the striking features of quantum mechanics. The chapter describes certain features of wavefunctions that are common to all the problems. The combination of features of wavefunctions with the solution of the Schrödinger equation results in one of the most characteristic features of quantum mechanics, the quantization of energy.

Abstract:
Abstract Polyatomic molecules can rotate and vibrate, as well as have translational motion. The number of degrees of freedom a molecule possesses depends on the number of atoms within it. Here we consider the simplest case - diatomic molecules. The single-particle partition function that we have dealt with thus far has only taken into account the translational motion of the gas, and has not included these rotational and vibrational effects.

Abstract:
This chapter treats rotations in three dimensions and the angular momentum quantum mechanically. The angular momentum is a 3-vector that plays the same role in the kinetic energy of rotating particles as the linear momentum 3-vector plays in the kinetic energy for translational motion. The quantum operator for the three components do not commute, i.e. the full vector cannot be known. Each component commutes with the operator for the square-length of the angular momentum vector, and therefore one opts for calculating the square-length and one of the components, z, referred to as the projection. The angular momentum is quantized. The (azimuthal) quantum number ℓ = 0,1,2,3… quantifies the square-length as ℓ(ℓ+1), and the projection is quantified by the (magnbetic) quantum number mℓ = -ℓ…ℓ in integer steps. The eigenfunctions are called spherical harmonics. A ‘rigid rotor’ model is set up to treat the rotational spectrum of a diatomic molecule.

Abstract:
This chapter explains the ideal diatomic gas in terms of internal degrees of freedom. It cites polyatomic species storing energy through translational motion, rotational motion, vibrational motion, and electronic excitation. The chapter discusses the separability of energy modes and shows that this allows for the calculation of a molecule's total energy. Additionally, the outcome of weak coupling assumptions will allow the formulation of the molecular partition function. This occurs separately for each energy mode as well. The chapter discusses factorizing translational energy modes and internal energy modes. Moreover, it notes that translational modes of motion can be applied to molecules carrying more than one atom in the same way in which they are applied to monatomic species.

This chapter focuses on the motion first on a circle and then on the surface of a sphere. It discusses the imposition of certain constraints on the wavefunction which shows how the energy and angular momentum of a rotating particle are quantized. It also examines the energy and the angular momentum of a rotating object which are quantized. The chapter reviews quantum mechanics and shows what they reveal about rotational motion. The chapter also considers a particle of mass m moving in a circular path of radius r in the xy-plane. It highlights translational motion which focuses on linear momentum, p and analogous angular momentum, J if rotational motion is considered.

Abstract:
The motion field for an observer moving through a static environment depends on the observer's translational and rotational velocities along with the distances to surface points. We show how the equations describing the motion field can be split by an exact algebraic manipulation to form three sets of equations, the first of which relates properties of the motion field to the observer's direction of translational motion alone. Therefore, to solve for the direction of translation, the depths and rotational velocity need not be known or estimated. Unlike previous surface-based techniques, we require no assumptions about the smoothness of the surface from which the optic flow measurements are taken, or that the measurements come from the same surface. Instead, we show that this procedure can provide a robust estimate for the direction of translation, given simply a sparse sampling of the optic flow from scenes that contain a significant variation in depth. Moreover, given this estimate we show how two linear equations can be found, one of which provides an overdetermined system of the rotational velocity alone, and the other contains only the relative depths. Again we show that the rotational velocity can be computed robustly, given a sparse sampling of velocities.

Abstract:
Numerical investigation of a bubble immersed in a liquid of different density inside a container subjected to translational oscillations under weightlessness reveals the following scenario: the bubble, initially centered, moves toward the container wall due to a non-viscous attraction mechanism. This motion is accompanied by small-amplitude oscillations at the forcing frequency and long-period eigen-oscillations induced by the initial acceleration. Concurrently, the bubble shape deforms, averaging over the forcing period, with flattening along the vibration axis and, under certain conditions, exhibiting parametric oscillations. A notable deceleration occurs as the bubble approaches the wall, stopping at a finite distance from the wall, without making contact.

Abstract:
Abstract In the food processing industry, particularly where naturally formed products are processed, complex shapes are frequently encountered. For example, in poultry processing, the shape of the products (chicken carcasses) is always a challenge. During processing, carcasses are transported, heated, cooled, washed, and cut. The thermal treatment of food requires the cooling and heating process be designed to meet certain conditions. This is despite the fact that products with heterogeneous properties and various sizes, shapes, and thicknesses are processed at the same time. Thus, the transport and thermal process cannot simply be predicted from previous work for well-defined shapes and sizes. Although more work is needed to understand the contribution of all the factors involved in processing, the current work focuses on the heat transfer and the complex geometry effect. The chilling process is a vital component of poultry production for both quality and safety. In order to prevent bacterial growth, the carcass core temperature needs to be cooled from 37–40 °C to 4 °C. Different poultry chilling systems exist within the industry to accomplish this task. Auger chilling is the most common method used in the United States, which is a process in which poultry carcasses are chilled by water immersion in a large tank with an auger. This has been the traditional method due to its efficiency in space along with its ease of implementation. Although auger chilling has been the traditional chilling method, in-line water chilling systems can be an alternative. In-line water immersion chilling creates a condition where a continuous line of carcasses hangs on shackles throughout the process. Potential benefits include enhancements in food safety, worker safety, economic, and processing labor requirements. Despite these benefits, inline chillers require a much larger spatial footprint due to the required dwell time. The objective of the current work is to improve a method of cooling by introducing relative motion between the carcass and the cooling medium (rotational kinematic component). Faster cooling reduces the dwell time of carcasses in the chiller, eventually reducing the footprint required which is the major drawback of in-line chillers. This experimental work will attempt to establish the difference and significance of two cooling conditions: 1. Cooling of complex shapes (chicken carcasses) in a still bath, and 2. Cooling of chicken carcasses under rotating motion. The experiment is designed to suspend chicken carcasses on shackles in a cooled ice water bath. The ice water is used to keep the temperature at a constant 0 °C. The built ice bath container mimics a typical processing line where chicken carcasses are suspended 30.5 cm apart. The container is 32.0 cm in diameter and 43.2 cm in depth and has a capacity to hold 34.7 liters of fluid. Two similar mass chicken carcasses are suspended by their legs and dipped into ice water, and the thickest part (breast) temperature is tracked. In fact, most food cooling processes are designed based on the worst-case scenario where the largest size is used to determine the thermal process requirement. In this case, the cooling process is evaluated by following the temperature history of the thickest part of the product, so cooling it guarantees that all the other parts are in cooled conditions. In this work, the experimental cooling rate of the suspended chicken carcasses for both cooling methods will be presented. Furthermore, this work will present models that can be used to predict the cooling process for both conditions.

Abstract:
When designing linkage mechanisms for motion synthesis, many examples have shown that the optimal kinematic constraint on the task motion contain too large deviation to be approximately viewed as a single rotational or translational pair. In this paper we seek to adopt our previously established motion synthesis framework for the design of cam-linkages for a more accurate realization, while still maintaining a one-DOF mechanism. To determine a feasible cam to lead through the task motion, first a kinematic constraint is identified such that a moving point on the given motion traces a curve that is algebraically closest to a circle or a line. This leads to a cam contour that is simple and smooth to avoid the drawbacks of cam mechanisms. Additional constraints could also be imposed to specify the location and/or size of the cam-linkages. An example of the design of a lower-limb rehabilitation device has been presented in the end of this paper to illustrate the feasibility of our approach. It is shown that our design could lead the user through a normal walking motion.

Abstract:
Abstract In this paper, the dynamic Modeling of the planar three-degrees of freedom platform-type manipulator is presented. A kinematic analysis is carried out initially, to evaluate and correct the initial coordinates and velocities. The dynamic model of the manipulator is formulated using a two-step transformation. Initially, the dynamic formulation is written in terms of the Cartesian coordinates of a dynamically equivalent system of particles. Since a particle does not have rotational motion, the differential equations of motion are derived by applying Newton’s second law to study the translational motion of the particles. A system of nine primary particles replaces the whole manipulator and the system mass matrix is derived. The equations of motion are then transformed to a more manipulator oriented variables; relative joint coordinates. This leads to efficient solution and integration of the equations of motion. Since the multibody system under consideration contains two independent closed kinematic loops, each of the two closed loops is cut at a suitable joints in order to produce a reduced open loop system with additional constraint equations. When the two cut joints are reassembled, the defined relative joint coordinates are no longer independent. They are related by the cut joint constraints. The constraint forces associated with the cut joint constraints are expressed in terms of Lagrange multipliers. Both cut joint constraints and constraint forces are then introduced into the equations of motion for the reduced open loop system to produce the resulting equations of motions of manipulator. A numerical example is presented and a computer program is developed.

Abstract:
Many spent fuels coming out of the nuclear power station are planned to be stored in the special site in Japan until they are reprocessed. In this site, the spent fuels are installed in a cylindrical container called canister. The canister, in tern, will be installed in the outer cylinder called cask that is a free-standing structure. When this system is subjected to strong seismic excitations, sliding or rocking motion will be induced. And, in the worst case, the cask may collide to each other or overturn. Therefore, it is very important to reduce sliding and rocking motions of the cask in order to avoid the consequent contamination of radio active substances. The authors have already reported the studies on the sliding and rocking motions of the cask subjected to a seismic excitation that contains a vibration system in it, and clarified the effects of the vibration of the inner canister. It was shown that the inner canister gives very large influences on the sliding and rocking motions of the outer cask. In this study, we applied a gyroscope at the top of the outer cask for reducing rocking motion of the cask. The effects of the gyroscope are studied for various excitation frequencies, excitation amplitudes and the structural dimensions of the gyroscope such as weight and rotational frequency. It is found that the gyroscope is very effective for reducing rocking motions of the cask-canister system subjected to seismic excitations.

Abstract:
Abstract Previously, the structure of a spatial stiffness matrix and its realization using a parallel elastic system have been addressed. This paper extends those results to the analysis and realization of a spatial compliance matrix using a serial mechanism. We show that, a spatial compliance matrix can be decomposed into a set of rank-1 primitive matrices, each of which can be realized with an elastic joint in a serial mechanism. To realize a general spatial compliance, the serial mechanism must contain joints that couple the translational and rotational motion along/about an axis. The structure of a spatial compliance matrix can be uniquely interpreted by a 6-joint serial elastic mechanism whose geometry is obtained from the eigenscrew decomposition of the compliance matrix. The results obtained from the analysis of spatial compliant behavior and its realization in a serial mechanism are compared with those obtained for spatial stiffness behavior and its realization in a parallel mechanism.

Abstract:
Directed hierarchical self assembly (DHSA) involves the purposeful assembly of a series of different subunits over multiple length scales to create arbitrarily shaped, large structures. We are developing a two stage DHSA procedure comprising of a coarse “far field” fluidic process which brings the sub-elements into the general vicinity of the assembly point and a fine “near field” process which completes the process. In the experiments presented here our sub-elements comprise of lithographically patterned silicon “microtiles” which are 500μm in size and contain a series of functional elements. The far-field assembly of these tiles is controlled fluid dynamically by modulating the translational and rotational shear forces applied to the tiles with a microfluidic structure. The near-field assembly is controlled through on board (i.e. on tile) microchannel jets/sinks, the strengths of which are modulated through the assembly or disassembly of thermally actuated gel based microvalves. This provides two fundamental levels of system control, namely control of the magnitude and direction of fluid flow, as well as addressability and control of each assembled component through on tile valves. In this paper we present our preliminary work on the fundamental fluid mechanics of this assembly at these two stages. In the first section we look at fluid motion and forces using CFD based numerical simulations. In the second we study a valving system based on an aqueous solution of a triblock copolymers that form a gel at temperatures near room temperature.

Abstract:
The UC San Diego Large High-Performance Outdoor Shake Table (LHPOST), which was commissioned on October 1, 2004 as a shared-use experimental facility of the National Science Foundation (NSF) Network for Earthquake Engineering Simulation (NEES) program, was upgraded from its original one degree-of-freedom (LHPOST) to a six degree-of-freedom configuration (LHPOST6) between October 2019 and April 2022. The LHPOST6 is a shared-use experimental facility of the NSF Natural Hazard Engineering Research Infrastructure (NHERI) program. A mechanics-based numerical model of the LHPOST6 able to capture the dynamics of the upgraded 6-DOF shake table system under bare table condition is presented in this report. The model includes: (i) a rigid body kinematic model that relates the platen motion to the motions of components attached to the platen, (ii) a hydraulic dynamic model that calculates the hydraulic actuator forces based on all fourth-stage servovalve spool positions, (iii) a hold-down strut model that determines the pull-down forces produced by the three hold-down struts, (iv) a 2-D and various 1-D Bouc-Wen models utilized to represent the dissipative forces in the shake table system, and (v) a 6-DOF rigid body dynamic model governing the translational and rotational motions of the platen subjected to the forces from the various components attached to the platen. In this report, the rigid body dynamics is studied utilizing the platen twist (combination of platen translational and rotational velocities) and wrench (combination of force and moment resultants acting on the platen) following principles from the robotic analysis literature. The numerical model of the LHPOST6 is validated extensively using experimental data from the acceptance tests performed following the shake table upgrade, and the model predictions of the shake table system response are found to be consistently in very good agreement with the experimental results for tri-axial and six-axial earthquake shake table tests. The validated mechanics-based numerical model of the LHPOST6 presented in this study can be coupled with finite element models of shake table test specimens installed on the rigid platen to study the dynamic interaction between the shake table system and the specimens. Another important potential use of the model is to improve the motion tracking performance of the LHPOST6 through either off-line tuning of the shake table controller and/or development of more advanced shake table controllers.
