摘要

描述了一种适用于φ20mm管径的管道检测微机器人的驱动器

它由双压电薄膜、芯杆和配重质量构成。采用有限元分析的方法研究了双压电薄膜在不同边界条件下

驱动器在一阶固有频率处的稳态响应

得出双压电薄膜的压制角度为9°和63°时

驱动器的稳态响应较大。该结论可成为此类微机器人优化设计的理论依据。

Abstract

The PZT bimorph actuator for microrobot

which is suited for inspecting the pipe of φ20mm diameter were studied. The actuator is made of PZT bimorph

center shaft and mass. With different boundary conditions of bimorph

the response at the first mode natural frequency of actuator were analyzed. FEM( finite element method) were used. The conclusion can be reached that when the fixing degree is 9° or 63°

the response is larger than those of others. All these are the theoretical basis of optimization of this kind of microrobot.
