摘要
论文基于电场-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(I-onic 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.
Based on electro-chemical-mechanical couple acting mechanism, the present paper investi- gates the IPMC macro-deformation, as well as micro-mechanism using numerical simulation. Within the framework of large commercial finite element program software,a numerical analysis flow chart is presented and then the user-defined subroutines are incorporated. The numerical results about the typical IPMC cantilever for deflecting deformation have achieved. The paper highlights the efficiency of blocking force for laminate and heterogeneous deflecting deformation. Comparison of the present numerical results with those available experimental measurements shows that the present technique is rational and valid. This contribution provides a potential way to model and design more sophisticated IPMC-based products.
