摘要
建立了铰接式货车平车底架的有限元计算模型 ,对该底架进行了静强度、刚度、固有频率及振型计算 ,针对铰接式货车底架刚度弱的特点 ,提出了方案修改建议 。
The finite element model for articulated underframe of railway freight car body is established.Computations of strength,stiffness,inherent frequencies and vibration mode shapes of two underframe structures are complemented.The comparision study of the rationalities of two articulated structures is undertaken,and suggestion for imporoving the design is given.
