引言对整体车身来说,正常试验首先是以试验车身的刚度为主。一般说来,强度的问题只有对局部构造才是重要的:如果一个低碳钢车身的结构有足够的刚度,它也就有足够的强度。弯曲刚度和扭转刚度必须同时考虑。驱动系统在车身上的装置方法需要有一定的刚性,并且装置点要有精确的位置,这是非常重要的,因此车身壳体是按车轮位置连接到试验台架上。这些部位不但对车身结构其余部 Introduction The overall body, the normal test is based primarily on the rigidity of the test body. In general, the problem of strength is only important for local structure: if a low-carb steel body has sufficient rigidity, it will have sufficient strength. Bending stiffness and torsional stiffness must be considered simultaneously. It is important that the method of driving the system on the body of the vehicle needs some rigidity and that the point of the device be accurately located so that the body shell is connected to the test bench by wheel position. These parts not only for the rest of the body structure
