| Abstract: | The function of the frame is to carry the various components connected to the car and to withstand various loads from inside and outside the car. In this paper, by establishing the finite element model of the frame, the corresponding boundary conditions and load conditions under the typical conditions of torsion and bending were set, and the rigidity and strength of the frame were checked. The experimental results show that the frame can meet the design requirements when it encounters various working conditions, and the accuracy was verified. |
