摘　　要：提出了自适应后排气囊的概念,进行了气囊布置和袋型设计,搭建了CAE模型,并与物理试验结果对标。在系统仿真和物理碰撞试验中,对比带后排气囊和不带后排气囊时假人伤害值,评估了后排气囊对后排乘员安全性能提升的影响。结果表明后排气囊能有效降低乘员的伤害。The concept of an adaptive rear seat airbag was proposed,and airbag layout and bag shape design were studied.The CAE model was built,and it was compared with physical test results.In the system simulation and physical crash tests,the damage to the dummy in the cases with and without a rear seat airbag was compared,and the effect of the rear seat airbag in improving the safety performance of the rear passengers was evaluated.The results show that the rear seat airbag can effectively reduce damage to passengers.
