利用前期工作由单轴拉伸实验获取并验证的材料常数,进一步研究Mooney-Rivlin、Ogden和Yeoh三种应变能模型在绝缘弹胶物（DE）材料的平面机电响应建模。根据实际试验中的平面双向预拉伸、两面加电场的边界条件,确定机电驱动模型,根据在一系列预拉伸值下进行的系列平面机电驱动试验,研究材料常数的合理性和机电驱动模型的可行性。研究结果表明,4参数、6参数的Ogden模型及Yeoh模型均可反映DE材料的机电响应特性;模型参数合理可行;Mooney-Rivlin模型不适合DE材料的机电驱动。
This paper applied the material parameters obtained and evaluated from uniaxial extension test regression and fitting in our previous work to further study dielectric elastomer（DE） planar actuation modeling based on strain energy functions. Actuation experiments with a few prestretch values are performed and are presented coMPared with the Ogden,Mooney-Rivlin and Yeoh actuation models.The result shows that the material constants are reasonable and the Ogden models with N=2 and N=3 and Yeoh model are good and applicable to the DE actuation,but Mooney-Rivlin model does not fit.Future work will be focus on the application of the Ogden and Yeoh models in the actuator device.
