자동차 보강 프레임에 대한 구조 설계 및 해석

To achieve the structural safety of the vehicle, designs in various cases are carried out by using CATIA program. It is promoted the relaxation of stresses by collisions from the front portion, the side part and the rear portion of the vehicle. In this study, we conduct a variety of design of frames for the light weight frame of the vehicle and structural analysis, to protect the driver by adding reinforced frame. In the case of such a collision, there are maximum stresses greater than yield strength of steel and a very large local plastic deformation at the collision part.
