摘　　要：散热片的有限元模型是散热片进行结构分析的基础。对发电机散热片建立了有限元模型并进行应力分析。先利用CATIA软件建立散热片三维模型,再以IGES格式导入有限元软件Hyper Mesh中对其进行网格划分、边界条件和载荷施加等前处理。最后运用Opti Struct求解器进行求解计算,依据分析结果进行结构改进,选择最优方案,并验证其可行性。Finite element model of the cooling fins is the basis of structural analysis. In this paper, the finite element model is established and stress analysis of the generator′s heat sink is conducted. Firstly, the three-dimensional model of cooling fins is built by using the CATIA software;then, it is imported to the finite element software HyperMesh in IGES format to complete the pretreatment such as mesh generation, boundary conditions and load. Finally, solution computation is conducted with the OptiStruct solver, so as to choose the best program and verify its feasibility based on the structural analysis improvement.
