摘要
随着汽车安全领域的发展,针对汽车碰撞情况的减伤以及预警措施的研究已经有了很大的进步。但是目前由低速后撞产生的颈部挥鞭伤问题不容忽视。利用Hyperworks对汽车座椅及搭载BioRIDⅡ假人模型进行有限元仿真建模,并利用LS-Dyna进行低速后撞的虚拟仿真实验,得到BioRIDⅡ假人颈部的载荷及加速度数据,并针对影响座椅抗鞭打能力的几个因素利用正交试验进行多目标优化,找到最优的参数设置,使低速后撞情况下汽车座椅的抗鞭打能力有所提升并且达到C-NCAP的评分要求。
With the development of automobile safety,there has been a great progress in reducing injury and early warning measures against car collision.However,it is still a very important research topic because of the whiplash injury caused by low speed back impact.it use Hyperworks on car seats and carrying BioRIDⅡdummy model for finite element simulation modeling,and using ls-dyna to do low speed back impact of the virtual simulation experiment,measured the neck stress situation.In view of the factors influencing the seat whipped resistance using orthogonal experiment method for multi-objective optimization,to find the optimal parameter Settings.Make the car seat whipped resistance improved in the case of low speed back impact and meet the requirements of C-NCAP.
