摘要

超声电机支撑结构影响其机械性能和稳定性。刚性支撑对振动的阻尼作用明显，能量损失较大；基于柔性隔振的弹性支撑则存在结构局限性或柔性过大的缺点。为此，本文将结构突变的刚性隔振和柔性隔振方法相结合，提出适用于超声电机的突变结构弹性支撑的设计思想。针对塔形超声电机的结构和工作模态的特点，在自由和夹持边界条件下，对三种突变结构弹性支撑进行设计与仿真，最后确定采用“内厚基座十字形薄板支撑结构”作为塔形超声电机的支撑。实验证明，采用所设计的突变结构弹性支撑，具有很好的支撑和隔振效果，塔形超声电机运行稳定，最大空载速度为980 mm/s，最大输出力为1N。

Abstract

An USM’s supporting structure had much effect on its mechanical characteristics and stability. The rigid supporting structure had obvious damping effect on vibration and could cause large energe lossing. The elastic supporting structure based on flexible vibration-isolating had the shortcomings of either structural limitations or too much flexibility. In order to solve these problems, the idea of the elastic support with abrupt changing configuration for USMs were proposed by using both abrupt changing configuration’s rigid vibration-isolating method and flexible vibration-isolating method. Considering the structural characteristics and the operating modes of the tower-shaped USM, three kinds of the above supporting structure were designed and emulated and “the inner thick-base and crisscross-sheet supporting structure” was adoped as the supporting structure of the tower-shaped USM. The experimental results show that “the inner thick-base and crisscross-sheet supporting structure” offers good supporting and vibration-isolating effect, and the tower-shaped USM with the supporting structure run stably, which offers a maximal velocity with no load of 980mm/s and a maximum output force of 1N.
