| Abstract: | This paper established a finite element model of the BIW of a car. According to the sensitivity analysis about the stiffness of joints, the design variables are decided. And according to the modal analysis, the constraints are confirmed, so that the lightweight design math model about the BIW of the car is established. Based on the lightweight design,an optimal design program of the BIW is put forward. |
