摘　　要：功率模块是变流器的核心部件,对安全性要求很高,在设计时需充分考虑其结构强度,但设计不能富余太多否则会使成本大幅提高,因此,如何在充分保证其结构强度的前提下尽可能的降低成本成为必须考虑的问题。文章基于有限元分析理论,运用SolidWorks对功率模块进行结构强度分析,在设计开发阶段对产品进行模拟仿真,达到保证其结构强度的目的,同时可以优化产品结构以降低成本。The power module is the core component of the converter,and the safety requirements are very high.When designing,the structural strength must be fully considered,but the design can not be excessive and the cost is greatly increased.How to reduce the cost as far as possible without fully ensuring its structural strength has become a must to consider Based on the theory of finite element analysis,this paper analyzes the structural strength of the power module by using Solidwoks,and simulates the product at the design and development stage to ensure its structural strength,and can optimize the product structure to reduce costs.

关 键 词：功率模块 有限元分析 结构强度 SOLIDWORKS
