摘要

本研究以圆柱楔波超声马达(WW-USM)样机的实际驱动方式为基础。利用有限元软件3D ANSYS建立了定子与转子的接触摩擦模型，并对定子与转子的瞬态接触力学进行了仿真。给定实际条件下的位移和外力边界条件，选取合适的接触参数，测试解的理想收敛性，得到合理的结果，并估算出电机转速和转矩的性能曲线。在超声电机原型特性的测量中，利用压电感应、控制电压的大小对转子施加预应力来取代传统压缩弹簧造成转子受力不均的现象，避免影响电机性能。三维ANSYS仿真结果表明，定子与转子之间的接触摩擦模型是确定实际摩擦常数的关键。

Numerical Transient Analysis of a Wedge-Wave Ultrasonic Motor

This study is based on the actual drive mode of a prototype of a circular cylindrical wedge-wave ultrasonic motor (WW-USM). The contact friction model of the stator and rotor was established by the finite element software 3D ANSYS, and transient contact mechanics between the stator and the rotor were simulated. Given the actual conditions of the displacement and external force boundary conditions, the appropriate contact parameters, test the ideal convergence of the solution, obtain reasonable results, and estimate the motor performance curve of revolution speed and torque. In the ultrasonic motor prototyping of measurement characteristics, the use of piezoelectric induction, the size of the control voltage applied to the rotor pre-stressing to replace the traditional compression spring caused by uneven force of the rotor phenomenon, to avoid affecting the motor performance. The simulation results from 3D ANSYS indicate that the contact friction model between the stator and the rotor is crucial for the determination of the real constant.
