摘　　要：基于有限元仿真计算,对转向架构架横梁、侧梁连接处焊缝进行了疲劳强度分析,并提出了结构优化方案。结果表明,采用在构架横梁、侧梁连接处设置加强垫板的优化方案可有效加强构架的抗疲劳性能。On the basis of the finite element simulation calculation,the fatigue strength analysis is made on the weld at the connection parts of cross sills and side sills of bogie frames,and the structure optimization scheme is put forward.The result shows that the optimization scheme to install the reinforcement pad at the connection parts of cross sills and side sills of bogie frames can effectively improve the fatigue performance of frames.
