摘要
讨论了一种双压电薄膜驱动的微机器人 ,它适用于 2 0mm管径的管道检测。本文利用有限元分析的方法研究了双压电薄膜不同边界条件对微机器人驱动器固有频率的影响 ,对样机的实验结果表明理论计算和实验基本符合结论揭示了双压电薄膜微机器人依靠惯性冲击振动获得驱动的机理 。
A PZT bimorph microrobot had been studyed. It is suited for inspection of pipe which diameter is 20mm. With different boundary conditions of PZT, the natural frequency of microrobot may be different. So FEM( finite element method) was used to analyze it. Three samples to test the analysis result were also done. The analysis is conform to the experiment. All these is the theoretical basis of optimize the robot.
