摘　　要：介绍新型碳纤维复合材料地铁转向架构架基本参数、结构设计特点,建立有限元三维模型,参考标准UIC615-4和EN13749建立计算大纲及载荷工况,利用Hypermesh+Ansys软件联合仿真进行构架静强度、疲劳强度和模态分析,根据劳氏船级社工作服务准则对构架进行强度评估。计算结果表明:该构架强度满足工作要求,安全裕度较高,各阶模态较高,不会与车体发生共振。Basic parameters and structural design features of the new metro bogie frame made of carbon-fiber reinforce plastic are introduced.A three-dimensional finite element model was developed.The calculation outline and load conditions are established with reference to the standards UIC615-4 and EN13749.Static strength,fatigue strength and modal of the frame are analysed by Ansys and Hypermesh softwares.Based on Germanischer Lloyd guidelines,the strength of the frame is assessed.The calculation results indicate that the frame strength can meet working requirements with high safety margin,high modal of each order and without frame-car body resonance.
