摘要
该文利用I -DEAS软件对某客车三段式车架进行了模态分析 ,计算车架的模态振型 ,从整体考虑车架的刚度与强度问题 ;对该车架进行了动态激励下的响应分析 ,并对车架上几个关键点的响应特征进行了详细研究 ,从理论上对该车架的整体性能及局部关键点进行了评估。
A software I DEAS was used to analyze the mode character of a three part bus frame,to calculate its mode frequency and to discuss the whole frame's rigidness and stress.The frame response was analyzed by the dynamical exciter.The response of some important points were discussed.The whole character of the frame was theoretically evaluated.
