摘 要:利用有限元分析软件对方环形直线驻波超声波电动机的振子进行了动态设计,提出了一种环梁式双接触面的振子结构,该振子采用柔性铰链与支撑结构连接,实现力的输出。利用振子第9阶同频的两个正交的面内弯曲模态分别实现直线电机的正、反方向驱动。对影响振子模态及固有频率的主要结构参数进行了有限元数值分析。In this paper, a new type of standing - wave linear USM with square - ring vibrator was presented, which had two contact surfaces and a support structure with four flexure hinges for the power output. The working modes were the ninth bending in - plane vibration modes, which had almost the same frequencies and realized movement of forward and backward using the same power supply. Influences of main parameters of the vibrator as well as flexure hinges on vibrating modes and corresponding frequencies were numerically analyzed by ANSYS software.
