| Abstract: | During the 45 000 km road durability test of a pick up vehicle, the fracture problem occurs on the reinforcement sheet of the right bracket of rear bumper and the frame mounted rear bumper. The frequency response of the rear bumper is simulated and analyzed by MSC Nastran, and the fracture reason is found and the problem is solved. |
