振动的幅值、速度及其空间分布是超声电机的重要参数。本实验室已研制出一套完整的以激光测振仪为核心的自动测量装置。这种非接触测量技术的主要目的是获得定子表面特定位移的实验值。可以通过建模获得理论值，但在这些复杂结构中很难考虑非线性效应。在本文中，我们报告了测量系统，并给出了在两种类型的电机上所获得的一些结果。
Amplitude and velocity of vibration and their spatial distribution are very important parameters for ultrasonic motors. A complete automatic measurement unit built around a laser vibrometer has been developed in our laboratory. The main object of this non-contact measurement technique is to obtain experimental values of the particular displacement on the stator surface. Theoretical values can be obtained by modelling but the nonlinear effects are difficult to take into account in these complex structures. In this paper, we report on the measurement system and we show some results obtained with two types of motor.
