摘要
双压电膜是由压电材料层、环氧树脂层、金属层组成的复合板。将双压电膜组合在一起构成管内移动微小机器人的驱动器。该文以压电本构方程为基础,建立双压电膜驱动器的机电耦合的有限元模型,采用有限元分析软件对双压电膜驱动器进行静态和模态分析,同时对驱动器静态位移与固有频率进行测试。将有限元分析与实验测试结果进行对比分析,两者的结果一致。
Piezoelectric bimorph, which consists of metal thin circular plate having PZT on both sides, is used as actuators of inpipe micro locomotive mechanism Based on piezoelectric constitutive equation, the finite element model is described in the paper By using software of finite element analysis (FEA), the analyses on static and modal of the bimorph were carried out The experiments was done to measure the deflections and frequencies, the results obtained from FEA are in very good agreement with those by means of testing.
