edge bending modes 边缘弯曲模式
A double-vibrator linear ultrasonic motor was designed to drive an exact linear transmission system. The motor consists of two symmetrical vibrators which use the bending modes to control the motion.
为提供驱动精密直线进给系统所需要的低速大力矩超声电机,提出了一种双振子型直线超声电机,该电机由2个对称的利用弯曲模态作为工作模态的摇头型振子组成,每个振子包含一个压电堆——它由4片夹心PZT-4压电陶瓷片组成。
