如果人们把发动机描述为汽车的“心脏”,那么作为汽车重要组成部分的车架就可以称为汽车的“骨骼”了。车架是汽车所有总成零件“生存”的载体,受力复杂。通过行走系和车身的力都作用于车架上,车架结构的好坏及载荷分配是否合理是汽车设计成功与否的关键因素。车架结构设计是否 If people describe the engine as the “heart” of a car, a frame that is an integral part of the car can be called the “skeleton” of a car. The frame is a vehicle for all the components of a car to “survive” and is subjected to complicated forces. It is the key factor to the success of the car design whether the frame structure is good or not and the load distribution is reasonable through the force of the walking system and the body. Frame structure design is not
