Abstract:
It is possible to create a control program for a two-mass system based on an industrial micro- controller. The software implements various control methods to reduce the dynamic loads in the kinematic elements during the transients. The methods of simulating the behavior of the mechanism in different condi- tions and time intervals is described, as well as demonstration of the system operation and registration of relevant data. Numerous studies have shown that mechanical vibrations in most cases adversely affect the operation of the electric drive, causing an increase in dynamic loads, which reduces the accuracy of the mechanism, the occurrence of mechanical vibrations that create a dangerous situation. In the transients, when the suspension point of the load moves with acceleration, there is a swing of the load relative to its equilibrium position. The aim of the work is to control the mechanism of horizontal movement by an indus- trial controller, which implements the reduction of loads in the kinematic transmissions during the transi- ents, increases the speed and dampens the oscillations of the suspended load. The task is to develop a control algorithm and demonstrate the possibility of implementing the necessary control laws of the industrial con- troller. The possibility of realization of a microcontroller control of the asynchronous electric drive of the translational movement mechanism with the suspended load is shown, the control algorithm providing re- duction of the dynamic loadings in the kinematic elements is developed, and at small values of a backlash it provides speed and damping of the fluctuations suspended on a flexible thread. The management program is implemented on the basis of the industrial controller. It is possible to demonstrate the operation of the sys- tem in real time, as well as, changing the scale of time, to investigate the dynamic loads arising in the kine- matic elements of the mechanism under different conditions and control methods.

Abstract:
A compact air separator demonstrator based on centrifugally enhanced distillation has been studied. The full size device is meant to be used on board of a Two Stage To Orbit vehicle launcher. The air separation system must be able to extract oxygen in highly concentrated liquid form (LEA, Liquid Enriched Air) from atmospheric air. The LEA is stored before being used in a subsequent rocket propulsion phase by the second stage of the launcher. Two reference vehicles are defined, one with a subsonic first stage and one with a supersonic first stage. In both cases, oxygen collection is performed during a cruise phase (M 0.7 and M 2.5 respectively). The aim of the project is to demonstrate the feasibility of the air separation system, investigate the separation cycle design, and assess that the separator design selected is suitable for the reference vehicles.<p><p>The project is described from original base ideas to design, construction, extended testing and analysis of experimental results. Preliminary computations for a realistic layout have been performed and the motivations for the choices made during the process are explained. Test rig design, separator design and technical discussion are provided for a subscale pilot unit. Mass transport parameters and flooding limits have been estimated and experimentally measured. Performance has been assessed and shown to be sufficient for the reference Two Stage To Orbit vehicles. The technology developed is found suitable without further optimization, although some volume and mass reduction would be desirable for the supersonic first stage concept. There are many ways of optimisation that can be further investigated. The aim of this program, however, is not to fully optimize the device, but to demonstrate that a device based on a simple, robust, low-risk design is already suitable for the launch vehicles. On top of that analysis, directions for improvements are suggested and their potentials estimated. A complete assessment of those improvements requires further maturation of the technological concept through further testing and practical implementations.<p><p>Directions for future work, general conclusions and a vehicle development roadmap have also been provided.<p><br>Doctorat en Sciences de l'ingénieur<br>info:eu-repo/semantics/nonPublished

Abstract:
Le monoxyde d’azote (NO) est connu pour ses nombreuses actions afin de maintenir l’homéostasie de la barrière intestinale, régulant la sécrétion de mucus, le stress oxydant, le système immunitaire… Le S-nitrosoglutathion (GSNO), donneur de NO naturellement produit par l’organisme, a montré une action bénéfique sur le renforcement de la barrière intestinale. L’enjeu est aujourd’hui de comprendre les mécanismes inhérents à cette observation. Pour ce faire une étude en Chambre de Ussing a été menée. Une fois le modèle d’étude validé par le suivi de marqueurs de perméabilité, les études histologiques et d’expression des protéines de jonctions cellulaires, le métabolisme du GSNO administré dans la lumière de l’intestin ont été explorés. Également, l’effet du GSNO sur la perméabilité de la barrière intestinale a été étudié. Les résultats permettent aujourd’hui d’envisager le GSNO comme une piste thérapeutique intéressante et prometteuse aux multiples applications possibles : intestinales, cardiovasculaires ou encore cérébrales<br>Nitric oxide is known for its many actions to maintain intestinal barrier homeostasis, regulating mucus secretion, oxidative stress, immune system… S-nitrosoglutathione (GSNO), a nitric oxide donor naturally produced by the organism, has shown a beneficial effect on the intestinal barrier reinforcement.

After the model validation, by following permeability markers, histological studies, and cell junction proteins expression study, the GSNO metabolism administered in the intestinal lumen was explored. Also, GSNO effect on the intestinal barrier permeability was evaluated. Results allow today to consider GSNO as an interesting and promising drug candidate, in the context of intestinal, cardiovascular or cerebral pathologies

Assuming the beams obeying the Euler-Bernoulli beam theory, the equations of motion of two beams and the attached masses are derived. By using the transfer matrix method and compatibility requirements of the spring attached points, the characteristic equation of the system can be obtained. From the system characteristic equation, the eigen-solutions of this system can be determined. Some numerical results are calculated and compared with the previous researches and an experimental method was used to validate the theoretical model.

Abstract:
碩士<br>國立雲林科技大學<br>電機工程系碩士班<br>92<br>In this thesis, speed control for a two-mass system with state-based sliding mode controllers are discussed. When designing the controllers, the desired action of two-mass system is decided, firstly. Then the suitable sliding surface is designed for the action. When the reaching condition is satisfied, the desire action can be achieved. The advantage of a state-based sliding mode control is that we can control the action of each state. In general, some state variables are not measurable in practical systems. Therefore, sliding mode state observer also introduced to estimate the states of the systems. Inorder to test the sliding mode controller, an experimental apparatus is established. An DC motor is used to drive the system. Two types of DC motor drivers torque and voltage (torque and voltage) are used. Realization, We simulate it by Simulink of Matlab. The simulation software becomes a program code through RTW to download to a DSP board. The proposed method is validate by using the experiment results.

Abstract:
Having shown at the end of Chapter 4 that mass/count may be encoded in the gender system, this chapter analyses in depth one Romance variety where the interaction of the mass/count distinction with gender presents itself in a distinctly intricate way, viz. Central Asturian. This features a ‘neuter’ agreement that has been variously analysed as the exponent of a value of the morphosyntactic categories gender or number, or as manifesting the value of some other, purely semantic, category. Complementing the evidence with new data, the chapter concludes that the most economical analysis is one according to which the Asturian neuter is a gender value, but within a second gender system. In this, Asturian parallels a few far-off languages which, in recent studies in linguistic typology, have been argued to possess two concurrent systems for noun classification.

Abstract:
This chapter compares two realist representations of the human body: Körperweltern (Bodyworlds), Gunther Von Hagens’s unprecedented public display of chemically preserved human corpses, and Cloaca, Belgian artist Wim Delvoye’s electromechanical replication of the functions of the human digestive system from ingestion to excretion. A comparison between these two displays points to the unexpected way in which the droll defecating machine creates more of a disturbance to the categories of true and false and human and inhuman than does the display which stages a confrontation between living spectators and dead human bodies. It contends that Cloaca’s realist approach may confront spectators with a potentially radically desubjectifying encounter.

Abstract:
Literature can be seen from two perspectives, contrasting a textual heritage sanctioned by cultural arbiters with a fluid scene in which written culture mutates according to the dynamics of open society. In China, a tradition of imperially sponsored bibliography, library formation, and cataloguing set out to standardize the mass of inherited writing. As libraries moved through cycles of formation, destruction, and reconstruction, they struggled to accommodate new work within traditional frameworks. Classification was an intellectual adventure that developed through two parallel traditions, in seven and four main parts respectively. By the eighth century ce, the four-part system imposed became dominant. Vast amounts of literature lost to direct transmission survived in edited collections that inevitably compromised the integrity of vanished originals. Conversely, finds in tombs, caves, and excavations have recovered a rich harvest of ancient writings, many of them previously unknown. The results have brought those two rival perspectives into direct confrontation.

Abstract:
This chapter discusses the N-body problem. In 1886, Karl Weierstrass submitted the following question to the scientific community on the occasion of a mathematical competition to mark the 60th birthday of King Oscar II of Sweden. Weierstrass asked that, ‘given a system of arbitrarily many mass points that attract each other according to Newton’s laws, try to find, under the assumption that no two points ever collide, a representation of the coordinates of each point as a series in a variable which is some known function of time and for all of whose values the series converges uniformly’. Henri Poincaré showed that the equations of motion for more than two gravitational bodies are not in general integrable and won the competition. However, the jury awarded the prize to Poincaré not for solving the problem, but for coming up with the first ideas of what later became known as chaos theory.

Full text
Abstract:
This chapter considers locomotion in living machines, focusing particularly on mammals and on the possibility of designing mammal-like quadrupedal robots. Locomotion is the movement of an organism or a machine from one place to the other, covering a defined minimal distance. In organisms, locomotion usually is driven by a central element and/or appendices. Vertebrates are characterized by the existence of a spine and the mechanics of an endoskeletal system. The amphibio-reptile type of vertebrate locomotion shows oscillations of the body stem mainly in the horizontal, which are coupled to the ground by legs with two long segments. The vertical oscillations of the body stem in the mammal type of quadrupedal locomotion are coupled to the ground by legs with three long segments. For any size of animal and any allometric relation between mass and ground reaction force the resonance mechanisms of gravitational and spring-mass-pendula are tuned to one each other. Elongated feet allow torque exchange with the substrate.

Full text
Abstract:
This chapter describes fiscal squeeze in an era of high political volatility and major economic challenges, including mass unemployment, a sharp increase in oil prices, double-digit inflation (i.e. a period of ‘stagflation’), and high levels of trade union militancy. The most dramatic period during the episode occurred in 1976, involving a split Labour Government under two different leaders, with a leadership election following a sudden prime ministerial resignation. That government pursued fiscal squeeze against the background of a deep currency crisis and bailout deals with outside lenders (the US Government and the IMF). The squeeze episode also led to some important institutional developments, producing the first major privatization since the 1950s and a new system of controlling public spending through ‘cash limits’.

Abstract:
In the shear force electromechanical valve (SFEMV) system, to unify and simplify the assembling process, a two-stage valve is employed. Three factors, mass distribution between the two sub-valves, the valve lash, and the direction of starting stimulation, are concerned for valve dynamic performance in the two-stage valve SFEMV system. With multi-domain modeling, eighteen cases are simulated to survey the impact of these three factors. Besides, experiments for interpretation of proper energy from the actuator are shown. To keep the energy from the actuator only used in overcoming friction, the results show that the current injection period should be precisely given, the mass of two valve stems should be the same as much as possible, and the actuator should turn to the valve closing direction at the beginning.

Abstract:
Vibration-based energy harvesting using piezoelectric materials has gained considerable attention over the past decade. Currently, most piezoelectric energy harvesters (PEHs) are single resonance frequency based. The performance of a single-resonance PEH is often limited to only one resonance frequency. This paper discusses the possibility of improving the performance of a bimorph PEH by tuning the PEH using a spring-mass system attached to the bimorph’s free end. Through adding the spring-mass system, the PEH’s resonance frequency can be tuned to match the ambient vibration frequency, and its voltage/power-generating capability can be improved. An electromechanical model of the PEH is derived based on the Lagrange multiplier method. The model is then used in a harmonic base excitation case study, and the coupled electromechanical outputs are discussed. Simulation results show that the spring-mass attachment can create two resonant frequencies, making the PEH capable of working efficiently at two different frequencies in a low-frequency level. It is also shown that by properly selecting the spring stiffness and the mass, the voltage and power output of the PEH can be greatly increased as compared to a single bimorph without the spring-mass system.

Abstract:
In the last years, researchers have presented concentrated and distributed parameter models of electromechanically coupled systems, leading to appropriate estimation of their electroelastic behavior. Equivalent electrical circuits have also been investigated and provide useful simulation tools to investigate the system behavior as well as to developed new energy harvesting or control circuits. In general, RLC (resistor, inductor and capacitor) circuits represent, respectively, the mass, damping and stiffness of single or multi-degree-of-freedom electromechanically coupled systems. In practice, however, the equivalent electrical representation of high-quality-factor systems demand equivalent circuits with extremely low internal resistance values. Furthermore, the assumption of an ideal transformer cannot be obtained in practice. This work presents a novel equivalent electrical circuit for linear and nonlinear electromechanically coupled systems. The effects of inductance, capacitance and electromechanical coupling are represented through operational-amplifier based sub-circuits of extremely low internal resistance. First, the linear behavior of a mass-spring-damping system is verified. Later, the behavior of a nonlinear electromechanically coupled system is investigated. In both cases, numerical results (Matlab-Simulink simulations) and experimental results (from breadboard implementations) will be verified against experimental results presented in the literature.

Abstract:
This paper presents a dynamic electromechanical model for an actuator system based on a Dielectric Electro-Active Polymer (DEAP) membrane biased with a linear spring. The motion is generated by the deformation of the membrane caused by the electrostatic compressive force between two compliant electrodes applied on the surface of the polymer. A mass and a linear spring are used to pre-load the membrane, allowing stroke in the out-of-plane direction. The development of mathematical models which accurately describe the nonlinear system dynamics is a fundamental step in order to design model-based, high-precision position control algorithms. In particular, knowledge of the nonlinear electrical dynamics of the actuator driving circuit can be exploited during the control system design in order to achieve desirable features, such as self-sensing or control energy minimization. This work proposes an electromechanical physical model of the DEAP actuator system. By means of numerous experiments, it is shown that the model can be used to predict the current by measuring deformation and voltage (electrical dynamics), as well as predicting deformation and current by measuring the voltage (electromechanical dynamics).

Abstract:
The transformation of waste vibration energy into low-power electricity has been heavily researched to enable self-sustained wireless electronic components. Monostable and bistable nonlinear oscillators have been explored by several researchers in an effort to enhance the frequency bandwidth of operation. Linear two degree of freedom (2-DOF) configurations as well as combination of a nonlinear single-DOF harvester with a linear oscillator to constitute a nonlinear 2-DOF harvester have also been explored to develop broadband energy harvesters. In the present work, the concept of nonlinear internal resonance in a continuous frame structure is explored for broadband energy harvesting. The L-shaped beam-mass structure with quadratic nonlinearity was formerly studied in the nonlinear dynamics literature to demonstrate modal energy exchange and the saturation phenomenon when carefully tuned for two-to-one internal resonance. In the current effort, piezoelectric coupling is introduced, and electromechanical equations of the L-shaped energy harvester are employed to explore the primary resonance behaviors around the first and the second linear natural frequencies for bandwidth enhancement. Simulations using approximate analytical frequency response equations as well as time-domain numerical solutions reveal that 2-DOF configuration with quadratic and two-to-one internal resonance could extend the bandwidth enhancement capability. Both electrical power and shunted vibration frequency response curves of steady-state solutions are explored in detail. Effects of various electromechanical system parameters, such as piezoelectric coupling and load resistance, on the overall dynamics of the internal resonance energy harvesting system are reported.

Abstract:
Equivalent electromechanical circuit analysis models provide efficient tools for analysis of power flow across multiple physical domains. In this work, we use this tool to develop a model of the power flow through mechanical, magnetic and electrical domains for analysis of magnetostrictive material-based devices. The magnetostrictive unimorph system in this study consists of a magnetostrictive galfenol (Fe-Ga alloy) layer bonded to a non-magnetic flexible metal layer, a pickup coil wound around the bimetallic strip and an electrical load. Permanent magnets are used to set a magnetic bias field and to provide a tip mass load at the free end of the cantilevered unimorph. The electrical load is connected to the pickup coil, such that vibration in the magnetostrictive alloy layer caused by the vibrating structure generates electrical energy that is dissipated by the electrical load, thereby damping the vibrations in the structure. The pickup coil output voltage varies with fluctuation in the magnetic flux density due to vibration of the beam. The electrical load discussed in this paper includes an inductance and a resistor (work that also includes capacitance is on-going). An electromechanical circuit model of the electrically loaded magnetostrictive unimorph system is used to study system dynamics. For this purpose the circuit description is simplified by a transformation of the electrical and magnetic elements into the mechanical domain. The network model of this system and simulations of its dynamic behavior are presented.

Abstract:
This article deals with a methodology for the computer-aided design of electromechanical actuators. In the frame of the preliminary design, it focuses on the selection and sizing of various components used in the actuator architectures. The addressed design criteria are the mass and reliability for given effort and speed profiles. The developed library of components for the simulation takes advantage of the non-causal and object oriented characteristics of the Modelica language. Thus, the library models can carry out an inverse simulation of the energy flows going from the mechanical load to the power source. Additionally, the number of parameters to be entered by the user has been minimized by the use of scaling laws, which return all the parameters that are necessary for the simulation. At the end of the article, the proposed approach is illustrated with the sizing and comparison of actuator architectures for an aircraft landing gear steering system.

Abstract:
In this paper, the nonlinear model of an asymmetric micro-bridge resonator with an attached eccentric mass is investigated. The resonator is treated using the Euler-Bernoulli beam theory. The attached mass represents the electrostatic comb-drive actuator in micro-electromechanical applications. The center of mass of the actuator is assumed to be off the neutral axis of the beam. The governing equations of motion are derived assuming that a concentrated harmonic force is applied to the attached mass. The nonlinear forced vibration of the system is studied using the method of multiple scales. It has been demonstrated that the eccentricity of the mass may lead to different types of nonlinear resonance, e.g., superharmonic and internal resonance. The end application of the structure under investigation is in resonant sensing and energy harvesting applications.

Abstract:
Subsynchronous oscillation (SSO) or torsional vibration may cause shaft of steam turbine generator hurt heavily. This phenomenon has destroyed two generator shafts in one of China’s power plant in 2008. Detailed analysis and several measurements have been taken to identify the reason of the accident. First, the operational data is analyzed, including field torsional vibration dada. Then, the modal of the shaft system is calculated. Each torsional vibration frequency is gotten with corresponding modal shape. Dangerous location of the shaft system is obtained. Third, torque value of different operation condition is calculated based on two different models: one is traditional multiple mass element rotor dynamic model and the other is an four mass element electromechanical model of rotor oscillation. Following, the maximum stress on the dangerous location is calculated using finite element method. Finally, the root cause of shaft destruction is analyzed and identified.
