摘要本文基于电场-化学场-机械场耦合作用机理，采用数值模拟方法，研究离子交换膜金属复合材料(Ionic Polymer Metal Composites 简称IPMCs)宏观变形的细观机理。借用大型商业有限元软件ANSYS开发平台，结合MATLAB编制用户子程序，制定了数值分析流程，给出了典型IPMC悬臂梁宏观挠曲变形结果。文章重点研究了IPMC板迭层结构的输出力效率、金属电极层的厚度最佳值和非均匀挠曲变形细观机理的宏观分析方法，计算结果与实验比较以显示数值方法的正确性。文章的研究结果对材料工作者合理的制作IPMC致动器产品，具有理论指导意义。
Abstract：Based on electro-chemical-mechanical couple acting mechanism, the paper investigates the IPMC macro-deformation, as well as micro-mechanism using numerical simulating technique. With the help of developing platform of large commerical finite element program software, the user-defined subroutines have been incorporated and numerical analysis flow chart has been presented. The numerical results about the typical IPMC cantilever for deflecting deformation have achieved. The paper highlights the efficiency of blocking force for laminate, optimal thickness of metal electrode layer and heterogeneous deflecting deformation. Comparing the numerical results with those available from experimental measurements has validated the proposed technique. The results pave the way for modelling and designing more sophisticated IPMC-based products.
