利用有限元分析软件I-DEAS建立了高速车体及转向架的有限元模型,通过对整车进行模态计算和响应分析,总结其振动特性,为车体的设计和改进提供参考依据。
The finite element model of high-speed car body and bogie was established by finite element analysis software I-DEAS. Through the modal calculation and response analysis of the whole car, the vibration characteristics were summed up to provide references for the design and improvement of car body.
