To solve the problem on rear bumper of a truck which has no functions of blockage and damping and energy absorption,rear bumper is optimized and simulative analysis and validation are carried out with LS- DYNA in accordance with related regulation of GB 11567. 2- 2001 concerning rear bumper. The simulation analysis of deformation velocity and deceleration show that the optimized design of the rear bumper after the performance has been optimized,can weaken the instantaneous impact,and avoid the rear car to impact the truck.
