摘　　要：运用ANSYS Workbench对一种新型绝缘子冲洗机构的伸缩臂进行静力学分析,并利用Design Exploration实现了以伸缩臂重量极小化为目标的截面参数优化。在满足负载要求的前提下,伸缩臂整体质量减少22.1%(17.9kg)。对处于工作状态的伸缩机构进行模态分析,研究优化后机构在该状态下的动态特性,结果表明:优化后机构在该状态下的动态特性良好,优化结果可行。In this study,we carried out static analysis of the telescopic arm of a new-type insulator washing device with ANSYS Workbench,and with Design Exploration,we optimized the section parameters aiming at maximum stress,maximum deformation and minimum weight of the telescopic arm. Under the premise of meeting the load requirements,the overall weight of the telescopic arm was reduced by 22. 1%（ 17. 9 kg）. We then carried out modal analysis of the telescopic arm at work,and the results showed that the optimized device had good dynamic performance,and that the optimization was feasible.
