绝缘弹胶物薄膜的褶皱与预防

褶皱是以绝缘弹胶物(Dielectric elastomer)(DE)为代表的电活性软物质材料与结构服役过程中的常见现象,也是影响DE器件使用的重用因素,其本质是薄膜的特征值屈曲。文章对绝缘弹胶物的褶皱与预防进行了数值研究。建立了绝缘弹胶物薄膜的有限元模型,计算了给定位移荷载下弹胶薄膜的变形;计算了在一定横向预拉伸作用力薄膜的变形和应力;最后通过前面不同工况的模拟结果,计算给出了不同位移荷载下,使得褶皱消除的临界预拉伸力,从而给出了绝缘弹胶物褶皱预防的一种新方法。

Numerical Study of the Onset and Prevention of Wrinkles with Dielectric Elastomer Membrane

Wrinkles,as one common phenomenon occurred together with soft matter membrane such as dielectric elastomer(DE),and structure service process is one of the most important factors that affects the normal application of DE apparatus.It is well known that the originality of wrinkle is eigenvalue buckling of membrane.This paper proceed numerical study on the onset and prevention of wrinkles of DE membrane,established finite-element model of DE membrane calculated deformation of DE membrane given displacement loa...
