- Abstract:
- The finite element model which takes a SUV as the object is established based on finite element a-nalysis,and this paper simulates the center and angle collision process of the rear bumper. It evaluates the per-formance of the rear bumper collision by analyzing the energy absorption characteristics. According to the laws and regulations, this paper simulates the 100% and 40% overlap of the rear part low-speed collision and ana-lyzes the collision deformation of every part, stress distribution and energy change, In the end,it verifies the rationality of the design. The results provide a basis for the further optimization of the structure and offer a new idea for the vehicle collision,and they are of great reference value for further study of the rear bumper, the ve-hicle collision simulation and real vehicle crash test.
