针对自制的弯曲型导电聚合物驱动器搭建试验系统,研究其弯曲运动特性。对驱动器施加(0~1 V)低电压,测量其顶端弯曲变形量;分析驱动器弯曲位移与电压的关系,建立了电压与应变的函数关系式。试验结果表明,电压与垂直方向位移成线性关系,电压为1 V时偏转位移可达到驱动器长度的一半,并且得到电压与应变的比例因子。参照驱动器的工作原理,对比驱动器的真实应变与热应变,建立热-结构耦合模型,并通过有限元法(FEM)求解该模型。通过对比仿真与试验结果,得出该耦合模型可以有效的模拟驱动器弯曲运动。

The bending motion characteristics were studied specific to the experimental system set up by home-made bending polypyrrole conducting polymer actuator. The bending deformation on the top of the drive was measured when applying the low voltage（0~1 V） to the actuator. The function relation between the voltage and the strain was established. The experimental results showed that the voltage was linear with vertical displacement. When the voltage was 1 V, the offset displacement might reach the half length of the actuator, and the voltage strain ...
