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 impact the truck.
某货车后保险杠碰撞仿真及结构优化研究
针对某载货汽车后保险杠无堵塞、阻尼和吸能功能的问题,根据GB 11567的相关规定,对后保险杠进行了优化设计,并利用LS- DYNA软件进行了仿真分析和验证。2- 2001关于后保险杠。对变形速度和减速度的仿真分析表明,优化设计后的后保险杠在性能得到优化后,可以减弱瞬时冲击,避免后轿车对载货汽车的冲击。
