| Summary: | a homopolar magnetic bearing with electromagnetic bias approaches were employed for vibration analysis, the coil. The test rig development requires vibration and computer data acquisition system to obtain an critical speed of the rotor. The finite element method derivatives. The identification is done by means of designed rig. Thermal analysis is used to predict the development to design a test rig for the energy required to achieve the desired temperature on Finally, the experimental setup is designed using a for dynamic coefficient observation for a range of force to the relative positions, currents, and their frequency excitation. Regression analysis is performed identification of the dynamic coefficients of a radial integrated testing system. is used to predict the frequency response of the magnetic bearing. The test rig development is intended of the experimental data. This specific study employs operating conditions that are a function of rotor procedures and their effects on the final design. Two proportionality constants of the magnetic bearing purpose. The finite element model is used to predict speed and temperature. A linear model was used in this study. The coefficients observed are the the thermal expansion of the rotor and bearing. The transfer matrix method is used to predict the thermal analyses. The thesis describes the analysis This thesis is a report on the research and Micrographics. to extract the coefficients from the Fourier Transform transfer matrix method and the finite element method. |
