Ness V/ I \ 4' 1966019609-005 i i INTRODUCTION 'I The complexity of space exploration, manned or unmanned, dictate_ the need for prior knowledge of the interaction of operations, materials and humans with the hostile environment of space. Grotmd simulation of these problems is a kighly challenging area of the entire space effort. This conference represents an attempt to outline the principles governing simulation in general, to explore its limits in design, fabri- cation and operation and to correlate early studies _ith information gain- ed from actual flights to date. A large fraction of the total investment of manpower, materials and money in the space effort will continue to be devoted toward ground sim- ulation of space environment and operations. Many scientists (from al3 branches of physical and life sciences) and engineers are engaged in this effort. It was the purpose of the conference to present to educational per- sonnel and to representatives from industry and government agencies the most recent efforts and results in the field of ground simulation, The benefits of such a conference to educational personnel are twofold; to acquaint them with the type of activity in which many of their present students will be engaged and to open new directions for their own in- vest igations, The participation of scientists from industry and government agencies was welcomed and it is hoped that by discussion they contributed to the general understanding and it is further hoped that they profited by association with others in their field. 1966019609-006 J CONFERENCE ATTENDEES LIST OF SPEAKERS GEORGE A.

Its 3D finite element (FE) models are estab- lished for sensitivity analyses on some parameters, such as air gap thickness, permanent magnet thickness, permanent magnet width, stator yoke thickness and four types of permanent magnet material, ferrite, NdFeB, AlNiCO5 and Sm2CO17 are conducted to achieve greatest thrust. Then its 2D finite element (FE) models are also established. The electromagnetic thrusts calculated by 2D and 3D finite element method (FEM) and got from prototype test are compared. Moreover, the prototype static and dynamic tests are conducted to verify the 2D and 3D electromagnetic analysis. The FE software FLUX provides the interface with the MATLAB/Simulink to establish combined simulation. To improve the accuracy of the simulation, the combined simulation between the model of the control system in Matlab/Simulink and the 3D FE model of the TPMLL in FLUX is built in this paper. The combined simulation between the control system and the 3D FE modelof the TPMLL is built. A prototype is manufactured according to the final designed dimensions. The photograph of the developed TPMLL prototype with thrust sensor and the magnetic powder brake as the load are shown.

He is one of the rare professors who will give his students to explore their research on their own, and in doing so, allows them to truly learn. Thanks are also due to my commitee, Dr. Henry Zmuda, Dr. Robert Moore, and Dr. Subrata Roy, for their encouragement and insightful questions. They put me at ease without going easy on me. I owe a debt of gratitude to Zhen Ning Low for taking the first steps on this project, for his help understanding power amplifiers, and for his friendship and conversation. He kept me sane. I thank Jason Taylor, Ashley Trowell, and Raul Chinga for their technical support, guidance, and friendship in working on this project. Thanks also go out to my parents and my brother, who always supported me, even if it did seem like my life was nothing but my research to the exclusion of all else. Finally, I’d like to thank Florida High Tech Corridor and Florida Department of Environmental Protection for funding and support. 4 TABLE OF CONTENTS page ACKNOWLEDGMENTS .................................. 4 LIST OF TABLES ...................................... 8 LIST OF FIGURES ....................................
