| 摘 要： | 以某厂家生产的沙滩车车架作为分析对象,在建立好车架的三维模型后,利用HyperWorks软件对车架进行满载弯曲工况、满载扭转工况、紧急制动工况、紧急转弯工况下的静力学分析,得到4种工况下车架的变形云图及应力分布,最后进行了车架的自由模态分析,得到车架前12阶固有频率和振型,为以后对类似车架的优化提供参考。

| Abstract: | This paper takes the ATV frame produced by a certain manufacturer as the analysis object.After establishing the threedimensional model of the frame,HyperWorks software is used to conduct static analysis of the frame under full-load bending condition,full-load torsion condition,emergency braking condition and emergency turning condition.And the deformation cloud diagram and stress distribution of the frame under four conditions are obtained.Finally the modal analysis of the frame is carried out to get the first 12 natural frequencies and vibration patterns of it,which is of great significance to the optimization of the frame in the future. |
