摘　　要：为开发出更低损耗要求的变压器,进行其结构尺寸优化设计是重要的技术途径之一。以型号S18-3150的变压器油箱为研究对象,使用SolidWorks创建了变压器油箱箱体及变压器油的三维有限元模型,基于流固耦合的方法对变压器油箱进行了静强度分析,通过灵敏度分析筛选出油箱零件壁厚度和加强筋厚度作为重要的设计变量,利用多目标遗传算法完成了油箱结构参数的优化设计,为变压器油箱改进设计提供了理论依据。In order to develop transformers with lower loss requirements,it is one of the important technical approaches to optimize the design of their structural dimensions.This paper took the transformer oil tank of model S18-3150 as the research object,using SolidWorks to create a three-dimensional finite element model of the transformer oil tank and transformer oil,and analyzing the static strength of the transformer oil tank based on the fluid-structure coupling method.Through sensitivity analysis,the wall thickness and reinforcement thickness of the oil tank were selected as important design variables.The optimization design of the oil tank structure parameters was completed by using multi-objective genetic algorithm,which provided a theoretical basis for the improvement design of the transformer oil tank.
