摘　　要：以交换箱(Swap Body)为研究对象,利用有限元分析软件Hypermesh、ABAQUS对某一交换箱箱体模型的结构强度进行数值仿真分析。结合BS-EN-283:1991欧洲国际标准要求和实际受力特点,分析七种不同工况情况下Swap Body箱体结构的Mises应力和挠度变形情况。根据获得的应力和变形等力学性能参数,对其结构进行多次优化和改进。有限元分析结果与试验数据基本一致,不仅能够为产品设计和结构优化提供理论基础,而且能够节省试验费用缩短设计周期。Taking swap body as the research object,the Finite Element Analysis software Hypermesh and ABAQUS are used to simulate the structural strength of a certain swap body model.Combined with the requirements of BS-EN-283:1991 European standard and the actual force characteristics,the Mises stress and deflection of the swap box structure under seven different operating conditions are analyzed.According to the obtained mechanical parameters such as stress and deformation,the structure is optimized and improved many times.Finite element analysis results are basically consistent with the experimental data,which not only provides the theoretical basis for product design and structural optimization,but also saves test costs and shortens the design cycle.
