摘要
通过分析电场活化聚合物材料的力学行为理论,建立了基于常见应变能函数(Mooney-Rivlin模型、Ogden模型和Yeoh模型)的电场活化聚合物驱动器的机电耦合本构模型。通过驱动实验,将3种机电耦合模型结果与实验数据进行了对比分析,得出影响电场活化聚合物机电稳定性的重要因素,确定了最适用于电场活化聚合物的机电耦合性能行为的模型。
The mechanical behavior theory of DE material was analyzed herein. The electromechan- ical coupling constitutive model of DE drive was built based on the common strain energy function, such as Mooney-Rivlin model, Ogden model, and Yeoh model. Through the drive experiments, the experimental data was compared with ones from three kinds of electromechanical coupling model. Then the important factors that affected the electromechanical stability of the DE were obtained, and the most suitable model of electromechanical coupling performance behavior used for DE material was determined.
