摘要
Abstract
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 im-pact the truck .关键词
