摘要

研究了冲击载荷对旋转型超声电机性能的影响。基于有限元方法，分析了不同冲击环境下超声电机的动态响应过程，分析过程中的关键材料选取了更接近工程实际的双线性随动硬化模型；通过实验方法对电机进行冲击测试，分析了冲击环境对电机机械性能与定子振动特性的影响。结果表明：转子的变形分为转子中心的下沉与转子边缘的扭曲两种状态；除了冲击幅值，冲击脉宽也会对结构的变形产生影响；在冲击环境中，超声电机的机械性能会降低甚至完全失效，而定子的振动特性也会产生畸变；橡胶能够在冲击环境中对超声电机进行有效的保护。

Abstract

The influence of shock environment on an ultrasonic motor was studied.The dynamic response of the ultrasonic motor under different impact load was analyzed based on the finite element method.The material model of key components was bilinear isotropic hardening model during the analysis process.The influence of shock environment on mechanical characteristic of the ultrasonic motor and vibration characteristic of stator was analyzed via experiment.The analysis results show that the deformation of the rotor can be divided into two states, the sinkage of rotor’s center and twisting of rotor.Bsides the amplitude, the impact duration also has influence on the deformation of the structure.The vibration characteristic of stator will have distortion besides the reduction of mechanical characteristic of the ultrasonic motor in shock environment.Rubber can protect the ultrasonic motor in shock environment effectively.
