摘　　要：联板类电力金具是超高压输电线路重要零部件,其性能关系到输电线路的安全稳定运行。为了设计得到结构强度高、质量轻便的超高压输电线路联板类电力金具,集成层次分析法、质量功能展开及ANSYS Workbench有限元仿真三种方法,得到针对超高压输电线路联板类电力金具结构的创新设计流程。利用该流程,以分裂悬垂联板为例,设计得到了一种具有高客户满意度、结构强度高、质量轻、高可靠性的新型分裂悬垂联板结构。在ANSYS Workbench软件的De⁃sign Exploration优化模块中,对初始设计方案进行结构优化,利用响应面法对小联板组厚度、角钢厚度和顶部联板孔距三个设计变量建立了二次回归模型,并利用MOGA算法对回归模型进行多目标优化,优化后的结构相对原设计方案安全系数提高了45.71%,质量下降了8.42%。The yoke plate type electric power fitting is an important part in EHV transmission lines.And its performance is related to the safe and stable operation of transmission lines.In order to design and obtain a yoke plate type electric power fitting with high structural strength and light weight for the EHV transmission line,three methods,including Analytic Hierarchy Process,Quality Function Deployment and ANSYS Workbench finite element simulation method,are integrated to obtain the innova⁃tion design flow for the structure of yoke plate type electric power fitting for EHV transmission lines.Using this method,taking the split suspension yoke plate as example,a new type of split suspension yoke plate with high customer satisfaction,high struc⁃tural strength,light weight and high reliability has been obtained.In the design exploration optimization module of ANSYS Workbench software,structural optimization is performed on the initial design scheme,and the response surface methodology is used to establish a quadratic regression model for the three design variables of the small yoke plate set thickness,the angle steel thickness and the pitch of the top yoke plate.And the MOGA algorithm is used to conduct multi-objective optimization.Com⁃pared with the original design scheme,the safety factor of the optimized structure is increased by 45.71%,and the quality is de⁃creased by 8.42%.
