摘　　要：以某轻型载货汽车车架总成为研究对象,进行了车架总成的扭转刚度、各种工况下的强度、模态等性能研究;在满足车架总成各种性能及结构尺寸要求的基础上,对车架总成进行轻量化设计;并通过台架试验和整车42 000 km可靠性试验验证车架总成是否满足设计要求。Taking the light truck as the studying object, the torsion stiffness, the stiffness under different situations, modes were ana- lyzed. Based on the performance and structure requirements of frame, the light-weight design was done. At last, the bench test and 42 000 km reliability road test were used to validate whether the performance of the frame met design requirements.
