儿童座椅对正面碰撞后排儿童假人伤害的影响

Research on the Influence to Rear Child Dummy Injury in Safe Seat in Frontal Crash Test

随着汽车被动安全的发展,对于儿童乘员的保护日益受到重视。C—NCAP 2012版中,要求在正面碰撞试验后排放置P3儿童假人,用于评价儿童约束系统。文章按照要求首先对比了各国法规中儿童假人的伤害评价方法,通过对不同车型试验数据的研究,讨论后排儿童假人伤害情况。并根据不同的因素,尤其是儿童安全座椅形式,对结果的影响进行分析。结果表明,上拉带式座椅保护效果最好;坐姿较直时对胸部伤害较小,但对头部伤害较大。该研究对于儿童假人的被动安全研究具有很强的实际意义。

With the development of vehicle＇s passive safety, the protection of chihtren passenger is increasingly paid more attention. In C-NCAP （2012 version）, P3 chiht dummy is added in 100% frontal impact test to evaluate child restraint system. Firstly, the paper discusses the child dummy injury evaluation method for different countries according to various test condition, the rear child dummy injury situation by different test data is studied. At the same time, it studies the influence to child dummy＇s injury especially for different rear safe seats based on different factors. The results show that the seat for upper tension belt type has good protet^tion effect, the injury to chest is small, but to head is serious. It has great significance for the development of child dummy passive safety.
