摘　　要：根据C-NCAP(2018)版鞭打试验评价规程和评分原则,利用仿真分析法研究了某驾驶座椅鞭打试验中假人的颈部伤害。依照鞭打试验规章建立了座椅鞭打试验的有限元分析模型,并与试验结果进行对标分析,验证仿真模型的有效性。研究结果表明:通过优化头枕杆的位置,减小头后高度,可改善鞭打试验中颈部伤害。According to the C-NCAP(2018)whiplash test assessment rules and rating criteria,the neck injury of the whiplash test was researched with simulation analysis method.Finite element model of the seat was established and verified the diagnostic test result.The research results show that the neck injury can be significantly reduced by optimizing of the head rest frame and vertical distance between the head and head rest.
