摘　　要：使用有限元前处理软件Hypermesh对某型动车组电热开水器进行网格划分,采用Optistruct求解器进行方程组求解,应用Hyper View进行后处理和数据分析,得出产品在标准工况下的应力大小及分布,然后通过实际试验验证有限元分析的结果,有限元分析得到的结果符合实际试验所测得的情况,此分析方法对某型动车组电热开水器的设计和改善起着重要的指导作用。Using the finite element pre-processing software Hypermesh to mesh the EMU electric boiling water heater products,using the Optistruct solver to solve equations,using HyperView analysis and postprocessing of data,obtained the stress in the product and distribution under the standard condition,and then through the actual test finite element analysis the results obtained from the finite element analysis results are consistent with the measured actual test conditions,the analysis method of a certain type of EMU electric boiling water heater design and improvement plays an important guiding role.
