摘　　要：建立了车架受力等效模型,并对中型载货汽车车架进行了弯曲工况和一轮悬空(扭转)情况下的强度及受力分析。采用CAD软件建立车架三维模型,并用Hyperworks软件做前处理,最后导入Ansys中求解。得出的计算结果与实际工况出现疲劳损伤一样,符合力学规律,因此认为等效简化力学模型是可行的。The paper established the frame stress equivalent model, and analyzed the stress and strength in frame of bending and one round suspending （reverse） cases. 3D＇ s model was Established modle with CAD, then did pre-treatment in Hyperworks, finally inducted the modle into Ansys to solve. The calculation results was the same as fatigue damage place in the actual operating mode, and conformed to mechanics rule, Therefore that the text equivalent of the simplified mechanical model is feasible.
