| 摘 要： | 通过CATIA软件建立某型地铁车辆转向架构架的三维实体模型,采用HyperWorks建立了该型地铁转向架构架结构强度分析的有限元模型,参照铁路相关标准,计算得到其强度分析应力结果,验证了该构架结构设计的合理性。通过模态分析,获得该构架的各阶模态频率及模态振型,为构架的动态特性设计提供参考。

| Abstract: | The geometric model of a subway bogie frame is established by CATIA software.The finite element analysis model of the bogie frame is set up by HyperWorks finite element analysis software.The stress results are calculated by strength analysis with reference to relevant railway standard.And the rationality of structure is validated,too.By modal analysis,the modal frequencies and modal shape are obtained.It will supply the reference for the dynamic characteristics design. |
