英文摘要：

The optimum design of ultrasonic motors involving the optimization of vibration mode,the determination of excitation pattern and area,the structural optimization,etc,was proposed to meet the motor work demand and to improve the motor output.A method for automatic optimization of ultrasonic motors based on MATLAB and ANSYS was presented in this paper,in which MATLAB conducted the optimization algorithm,established the parametric model based on APDL,and repeatedly called the ANSYS analysis to optimize the ultrasonic motor automatically.For instance,location setting and shape optimization of the driving tip of rectangular plate ultrasonic motors were investigated,and the call,interface and data exchange between MATLAB and ANSYS were discussed in detail.
