Thesis, Växjö University, School of Technology and Design, 2009. http://urn.kb.se/resolve?urn=urn:nbn:se:vxu:diva-5416.
Повний текст джерелаThe aim of this thesis was to evaluate the use of dynamic excitation as a method for stiffness and strength grading of wet side boards of narrow dimensions. The need for such an investigation has previously been identified in an ongoing research project in which the possibility to use side boards as lamellae in wet glued glulam beams is investigated.
The assessment of the dynamic excitation method was carried out by means of experimental work and measurements.. The approach was quantitative in the sense that the data was collected through experiments performed on a rather large population and that the results were analyzed using statistical methods.
To investigate the effect of moisture content on stiffness of narrow dimension, side boards, the stiffness was measured in three states:
- - in wet state, before splitting the boards,
- - in wet state, after splitting the boards, and
- - in dry state (splitted boards).
The conclusion, after calculations and analysis of all the results, was that the natural frequency and stiffness of wet boards could, with a high degree of reliability, be predicted by use of the dynamic excitation method. There was a strong correlation in stiffness between wet state split boards and dry state split boards, with a coefficient of determination of 0.93.

Повний текст джерелаThis thesis deals with the development of a continuous element for orthotropic, sandwich and multilayer plates. This approach is based essentially on the construction of the dynamic stiffness matrix of orthotropic plates using natural boundary conditions from a reformulation of the isotropic plate elements developed in the QUARTZ laboratory (EA 7393). In order to develop the dynamic stiffness matrix of the studied element we resort on the first hand to the decomposition of free boundary conditions described by Gorman, on the second hand to the resolution of the equations of motion by using Levy series expansions. The dynamic stiffness matrix is then obtained by projecting movements and frontier efforts on functional bases compatible with assembly operations. Finally the continuous sandwich and multilayer plate element is described by superposition of continuous orthotropic plates element previously developed.The formulations presented takes into account the bending vibration and the vibration in the plane, called membrane vibration. The validation of all obtained results is conducted by a systematic comparison of undamped harmonic responses with those obtained by various finite element models

Повний текст джерелаThis thesis follows some previous work of the CRONE team applied to carsuspensions. It allows to purpose one car suspension, called CRONE car suspension, whichimproves the compromise between low frequency road filtering and car holding and thecompromise between hight frequency road filtering and wheel holding. To hold the wheel acriterium on the wheel holding is developed. This criterium can be used to analyse and tunedall kind of car suspension around the wheel pulsation. Moreover, to fight against thecompromise between the driver input and the raod input, a control laws is developed andapplied to a bi-state car suspension called hydractive car suspension. Finally, the influence ofthe car suspension tuning on the vehicle dynamic and more precisely on the ESP, ABSsystems is studied and illustrated with some first experiments

To solve soil-structure interaction problem, finding the foundation impedance is an important part in using sub-structure technique. To find the impedance, finite element method is employed. The commercial program ABAQUS is used for the finite element method. Firstly, we set up an ideal finite element model and analyzed it to obtain numerical solutions. Then we compared the numerical solutions with the analytical solutions in order to examine the accuracy and convergency of the finite element method. Finally, extending the result of the convergency analysis to calculate the impedance of embedded square foundation by finite element method.

In this research, critical speed analysis of asymmetric rotor systems was performed by using the dynamic stiffness method. The asymmetric rotors are different from the common symmetric rotors in that the properties at the cross sections of the rotors are not axisymmtric. The dynamic stiffness matrices of shaft elements are derived with Rayleigh beam modeling. The element matrices are assembled with the matrices of disks and bearings to form the system matrix, where the compatibility and equilibrium conditions have to be fulfilled at the joints of the elements. Synchronous critical speeds and subcritical speeds of the asymmetric rotor-bearing systems are analyzed under the effects of various conditions. Damping effects on the stability of the asymmetric rotors are also investigated.

Frozen shoulder is a functional disorder related to shoulder muscles. Among many treatment strategies, rehabilitation exercise is one of the most common and viable therapy. In this research, a new 8 degrees of freedom (DOFs) rehabilitation robot arm named NTUH-II has been developed for frozen shoulder rehabilitation in our laboratory. The robot arm is able to provide most of upper limb rehabilitation motions in passive, active, and assistive modes. There are many improvements for NTUH-II from the previous version NTUH-ARM, also developed in our laboratory such as larger shoulder flexion/extension range of motion, shoulder localization with laser tools, side-changing, and shoulder traction. This work combines knowledge from rehabilitation medicine to robotic engineering. From the nature of muscle stretching, the exponential torque-angle relationship curve can be found, and thus it is possible to model and evaluate the condition of the patient’s motion quality. The use of two parameters, stiffness and control authority, is proposed in this work. Based on these two parameters, an adjustment method of dynamic stiffness model and assistance torque gain is developed and implemented on NTUH-II. The control algorithm proposed in this research can customize the rehabilitation to meet the individual needs of frozen shoulder patients. Various experiments have been conducted on healthy subjects in National Taiwan University Hospital, and appealing performance has been observed, which validates the method proposed in this paper.
