摘要： 为获得汽车座椅一些关键参数对鞭打试验结果的影响规律,同时进行了计算机仿真与试验,并将仿真结果与鞭打试验结果进行对比,在确认了计算机仿真可行且准确的基础上,进行了多轮的仿真计算。结果表明:靠背刚度越小和靠背转动刚度越大,则鞭打试验得分越高,且靠背刚度比其转动刚度影响更明显;头枕刚度和头枕转动刚度越大,则鞭打试验得分越高,其中,头枕转动刚度的影响更明显;而头枕越高和头后间隙越小,则越有利于鞭打试验得分。

Abstract: In order to obtain the law of the influence of some key parameters of car seat on the results of whiplash test, both computer simulation and test are conducted, and the results of simulation are compared with test data. After the feasibility and accuracy of simulation are verified, a few rounds of simulations are carried out. The results show that the smaller the backrest stiffness and the greater the rotational stiffness of backrest, the higher score the whiplash test will get, with the effect of backrest stiffness is more obvious than that of rotational stiffness. The greater the headrest stiffness and the headrest rotational stiffness, the higher score the whiplash test will get, in which the effect of headrest rotation stiffness is more obvious. The higher the headrest and the smaller the headrest back gap, the higher score the whiplash test will get.

Key words: car seat, headrest, whiplash test, simulation
