摘　　要：采用ANSYS软件对SF6变压器气箱进行应力分析,得到箱体结构的应力和位移分布。分别选取箱盖、箱壁的最大等效应力和最大位移变形作为优化目标,采用正交试验方法分析各参数的影响,得到加强部件的最优分布情况。进而采用APDL参数化方法,分别提取箱盖厚度、箱沿厚度及定位件厚度等参数作为设计变量,以体积轻量化为目标进行优化设计。结果表明:优化后结构总体积比原结构降低了15.2%,为气箱结构后续改进及优化提供参考。In this paper,the ANSYS software was used to analyze the stress on SF6 transformer＇s gas box and the stress and displacement distribution of the box structure were obtained. Through taking maximum equivalent stress and the maximum displacement deformation of the box cover and the box wall as the optimization objectives,respectively,the orthogonal experimental method was adopted to analyze the influence of each parameter so as to obtain an optimal distribution of the reinforcement components. Through making use of APDL parameterization,the five parameters,including the thickness of the box cover,that of the box rim and the locating piece were taken as the design variables and the lightweight design was optimized. The results show that,the structural volume after the optimization is 15. 2% lower than that of the original structure. It provides reference for the improvement and optimization of the gas box＇s subsequent structure.
