摘　　要：在北京地铁1号线东段车辆转向架大修中发现,齿轮箱吊座出现了裂纹。构建了该车辆转向架构架上的齿轮箱吊座的有限元模型并对其进行了相应的结构优化,优化后的齿轮箱吊座强度和刚度均有所增大,达到了结构优化设计的目的。Some cracks have been detected in the gear-box bracket on the bogie frame,in the overhaul of Beijing metro Line 1 vehicles.In this paper,a finit element model of gear-box bracket on metro vehicle bogie frame is established and optimized correspondingly,which has higher stiffness and strength,and has reached the goal of structural optimization in the design of gear-box bracket.
