摘　　要：以某运输车车架为研究对象,通过CATIA建立三维模型,用Hyperworks对车架有限元模型进行模态分析。通过模态分析得到了车架的固有频率和振型,为分析、设计和优化此类车架提供理论依据和参考。As the research object,the model of the truck frame is built by the CATIA software,then the modal analysis were analyzed for the frame by the Hyperworks software.Through the modal analysis,the natural frequency and vibration mode of the frame were got,we can find some theoretical basis and reference to analysis,design and optimization of this kind of frame.
