【Abstract】 Magnetic Suspension Rotor (MSR) system supported by active or passive magnetic bearings has more advantages than the traditional one supported by conventional bearings. Virtual Prototyping (VP) is an advanced design method to reduce the design mistake and improve design efficiency. To improve design quality and reduce the developing time and cost of MSR system, modeling techniques and virtual prototype of MSR systems are researched. The main work and achievements are as follows:According to the characteristics of MSR system, the multi-disciplinary collaborative simulation model’s development process of the system based on ADAMS is developed. The architecture, technique and function of MSR system’s VP design system are studied. Then, diversified techniques of the system are researched, which are parametric modeling, multi-disciplinary field modeling, secondary development techniques of ADAMS, and so on.The active and permanent magnetic bearing design of the VP is researched. The structure design and performance simulation modules of the magnetic bearing are developed. For the design of the permanent magnetic bearings, the structure and the analysis method of magnetic field are studied, especially, the modeling of multi-ring axial magnetized permanent magnetic bearings. The bearing capacity is calculated through FEM (Finite Element Method). The method is applied into the design the rotor-support system of small wind power generator. The experimental prototype is completed. This design reduces the wind generator starting resistance torque, in compare to the conventional wind power generator. The result shows that the method is feasible and effective.The modeling methods of multi-disciplinary field are introduced. The modeling of multi-disciplinary field of MSR system and collaboration technologies between ADAMS and other software are researched. Based on the mechanical & electrical modeling of the magnetic rotor system, the model of mechanical system and the control strategy are established by using ADAMS and Matlab/Simulink. By integrating the control strategy and mechanical system, the model of unified VP of the five-DOF MSR system is developed. The co-simulation and the sensor’s measuring problems are discussed.According to the flexible multi-body system modeling theory and ADAMS flexible modeling method, the ADMAS, MATLAB and ANSYS combined simulation model of the flexible MSR system is established.The dynamic model of the MSR system in consideration of base motion which is applied into vehicle flywheel battery is built.更多还原
