Abstract:
The component of ground reaction force (GRF) acting perpendicular to the leg in the sagittal plane during human locomotion (acting in a rotary direction) has not been systematically investigated and is not well understood. In this paper, we investigate this rotary component of the GRF of 11 human subjects (mean age ± s.d.: 26.6 ± 2.9 years) while walking and speed walking on a treadmill, along with eight human subjects (mean age ± s.d.: 26.3 ± 3.1) running on a treadmill. The GRF on both legs was measured, along with estimates of the subject's mass centre and the centre of pressure of each foot to yield total leg lengths and leg angle. Across all steady walking and running speeds, we find that the rotary component of the GRF has significant magnitude (peak values from 5% to 38% of body weight, from slow walking to moderate running, respectively) and implies leg propulsion of the mass centre in the rotary direction. Furthermore, peak rotary force magnitude over stance increases with locomotion speed for both walking and running ( p < 0.05), and the time-averaged (mean) rotary force shows a slight increase with walking speed (though the mean force trend is uncertain for running). Also, an estimate of average power input from the rotary force of the leg acting at the mass centre shows moderate and strong positive correlation with locomotion speed for running and walking respectively ( p < 0.05). This study also shows that the rotary force acts differently in walking versus running: rotary force is predominantly positive during running, but during walking it exhibits both positive and negative phases with net positive force found over the whole stride.

Abstract:
This work presents inspection method for component of indexing table. The indexing table employs a vee and 3 balls kinematic location system. The 6 points contact kinematic design concept of ball and vee groove was used, because the ball and vee groove system can attain good repeatability and has good rigidity. The vee plays an important role as the indexing angle and locking mechanism. Also eccentricity is an important factor as alignment between the rotation center of the rotary table. So, the concentricity between the center of the vee plate and the center of the rotary table is required to be as close as possible to make an accurate vee plate. The indexing table uses the kinematic design concept of vees and balls. But contact stress in the vee is often very high, so the plastic deformation could occur on the vee due to the loaded balls. The elastic deformation of cam shaft is described in this paper.

Porosity, or fractional void volume, is a simple but powerful quantity used in describing porous media. Characterising this very important parameter is vital to understanding key processes that occur in porous media, such as fluid transport. This is because porosity is strongly related to the permeability of porous media.

This thesis is aimed at detecting adjustable-speed motor rotary faults and implements an intelligent diagnosis system. The system measures the vibration signals by using the wireless sensor node mounted on the motor. A sensorless speed estimation algorithm is developed to find out the mechanical rotary frequency of adjustable-speed motor. Moreover, the principal component analysis is used to intercept the fault characteristics. Finally, the system adopts the dynamic structure neural network to establish the diagnosis functionality. Since the traditional rotary motor fault diagnosis system is only capable of diagnosing a fixed-frequency fault, it is not suitable for adjustable-speed motors. Therefore, this thesis estimates the rotary speed of adjustable-speed motor via zero crossing detection method. Furthermore, the rotary frequency of the adjustable-speed motor is calculated for fault diagnosis. In addition, as the motor operates at low-frequency, the amplitude of fault characteristic frequency is decreased and the influence of noise is increased. As a result, the diagnosis module is easy to generate a false alarm. To overcome this difficulty, this thesis uses the concept of principal component analysis to extract the fault characteristic parameters. Not only the convergence speed in the neural network training is increased, but also the noise effect is eliminated. Hence, the identification accuracy in the fault diagnosis is increased. This thesis uses the MATLAB software to develop the modules of signal process, zero crossing detection, and neural network and uses the Visual Basic software to implement the Human-machine interface. Finally, a test platform is used to generate the faulty motor vibration signals and perform vibration experiments. From the experimental results, the implemented intelligent adjustable-speed motor rotary fault diagnosis system is found capable of identifying adjustable-speed motor rotary faults.

Abstract:
Clinicians typically assess the functional status of the knee subjectively through manipulations to the knee’s passive connective tissue restraint under minimal load. The resulting translation or rotation at a given flexion angle is defined as the laxity of the knee which is used to suggest (in)stability. However, recent studies have shown that instability is not necessarily determined by knee laxity1. Dynamic stability at the knee is achieved through a complex interaction between soft tissue structures, neuromuscular control and articular geometry. It is during dynamic functional movements, such as walking, that patients suffer from buckling or giving way sometimes resulting in falls 2.

Full text
Abstract:
Many devices involve sliding contact where a rotating component slides over a stationary component. Examples include disk brakes, cam/valve lifters, and laboratory pin-on-disk machines. An essential feature of these devices is that a wear track forms on the rotating component that is cyclically exposed to frictional heating, temperature fluctuations, and enhanced chemical film formation. The objective of this paper is to develop a theoretical model and solution methodology to examine the thermal effects produced by friction between sliding contacts in systems with rotary motion. A new methodology based on a combination of control volume finite difference and the cellular automata concepts is developed. The method involves a cascading sequence of simple, explicit rules of evaluation, rather than complicated partial differential equations. Results using the general model developed in this study are presented in dimensionless form to show the importance of critical operating parameters. Implications for applications such as disk brake and cam/valve lifters are suggested.

Abstract:
The U.S. Army Engineer Research and Development Center, Construction Engineering Research Laboratory (ERDC-CERL) is developing a new class of flexible, generative textile as a novel means of sustainable wind energy generation. Flexible, generative carbon nanotube (CNT)-based textiles may have excellent potential for electrical capacitive storage and reuse in conjunction with small-scale energy-harvesting systems, both from wind for fixed applications and from human locomotion. This paper describes the design and optimization of a three-layer generative textile composed of discrete layers for generation, distribution, and storage. Initial results suggest that improvement in the generation layer will provide the highest increase in overall performance. The output of the electromagnetic tests shows a power density of 0.17 mW/cm3. However, the efficiency can be significantly improved through increasing the voltage output of the generation layer from 20 mV to around 1V. In an analysis of the operational envelope, wind data collected locally at ERDC-CERL and at other sites around the world reveal close similarity in the probability distributions, which could allow for a practical engineering approach capable of harvesting the steady “ram” component in addition to a variable energy component of the wind. To further study the textile-wind interactions, a wind simulation environment is being developed and has been able to obtain reproducible wind speed data thus far.

Abstract:
Drilling is an essential practice, especially for the aerospace industry. Conventional machining procedures such as twist drilling are not cost effective for hard to machine materials such as titanium, advanced ceramics, carbon fiber reinforced plastics etc. Rotary ultrasonic machining (RUM) is a nontraditional machining process for hard to machine materials. RUM utilizes a rotating, ultrasonically vibrating tool (core drill) feeds into the workpiece to remove the material. Although drilling is the most common machining process for CFRP, delamination is a major problem associated with drilling, because of its heterogeneity and anisotropy. Delamination reduces structural integrity and increases assembly tolerance which leads to rejection of a part or a component. In the air craft industry, rejections caused by delamination accounts for 60% of all rejections in final assembly. This motivates researchers to identify delamination-free techniques to reduce component rejection caused due to delamination. This paper, for the first time, investigates the effects of process parameters on the delamination of CFRP processed by RUM. These process parameters are variable feed rate, variable spindle speed and the use of backing plate.

Abstract:
In driven rotary cutting of stainless steel, adhesions sometimes occur on the tool, causing increased wear. The type of coolant supplying methods and tool rotation speed affects largely on the adhesion because it depends on the temperature and lubricating performance. Results showed that in a circumferential velocity ratio of 1.0, which means tangential component of tool peripheral speed is equal to work surface speed, there is no adhesion on the tool after cutting. In a circumferential velocity ratio of 2.0, adhesion occurred with overcooling of the flood coolant, and wear increased by adhesions to the rotating tool. It was found that the thermal cracks on the cutting edge was one of the factors of increased wear and chipping. Adhesives on the tool edge also accelerated the chipping.

Abstract:
Abstract In this paper, we present a dynamic model for a generic drill-string. The model is developed with the intention for component-based simulation with coupling to external subsystems. The performance of the drill-string is vital in terms of efficient wellbore excavation for increased hydrocarbon extraction. Drill-string vibrations limit the performance of rotary drilling; the phenomenon is well-known and still a subject of interest in academia and in industry. In this work, we have developed a nonlinear flexible drill-string model based on Lagrangian dynamics, to simulate the performance during vibrations. The model incorporates dynamics governed by lateral bending, longitudinal motion and torsional deformation. The elastic property of the string is modeled with mode shape functions representing the elastic deformation, with a finite set of modal coordinates. By developing a bond graph model from the equations of motion, we can ensure correct causality of the model towards interacting subsystems. The model is analyzed through extensive simulations in case studies, comparing the qualitative behavior of the model with state-of-the art models. The flexible drill-string model presented in this paper will aid in developing simulation case studies and parameter identification for offshore drilling operations.

Abstract:
The study proposes an improved Gabor order tracking (GOT) technique to cope with crossing orders that cannot be effectively separated by using the original GOT scheme. The improvement aids both the reconstruction and interpretation of two crossing orders such as a transmission-element- related order component and a structural resonance. The dual function of the Gabor elementary function can affect the precision of tracked order components. Its influence on the computed Gabor expansion coefficients is investigated in the study. For applying the improved GOT in practical works, the separation and extraction of close-order components of vibration signals measured from a transmission-element test bench is illustrated by using both the GOT and Vold-Kalman filtering OT schemes. Additionally, the ranking of noise components from a riding electric scooter is demonstrated.
