摘要应用 UG 软件的模块集成功能,建立车架结构高度仿真的三维模型和有限元分析模型,快速有
效地进行车架静力学和动力学特性分析,研究车架结构设计在静载荷下性能的符合性以及在动载荷下
的模态参数和振动特性。经分析研究力学特性,找到车架结构设计上的缺陷,有针对性地提出结构改进
方案,并再次进行有限元分析和验证。通过改进方案的比对分析,得到符合约束条件和工艺要求的车架
设计方案。

Abstract The integrated module for CAD and CAE of UG is applied to establish a more effective simulation

model which contains three dimensional digital model and finite element analysis model which are engaged in
the dynamic and kinematic analysis for the frame of motorcycle. The frame structure is analyzed to check its
performance under static load and its mode parameter and vibration characteristics under dynamic load. Then
,
the design fault of frame is studied to make an improvement design to the frame and the frame is analyzed by
finite element method again to check its performance. After several refined designs for the frame pari-

son the final design project of frame is developed which is in accordanc
