摘要：为降低追尾时的挥鞭伤危害，提出一种座椅靠背型面优化方法，论述该方法对头后间隙的影响机制。基于该方法对某款座椅的鞭打性能进行优化，根据CNCAP规程进行试验验证。结果表明：该方法对座椅造型的影响程度较小，优化目标与试验结果吻合较好，假人颈部伤害值降低16.6%，上颈部载荷与下颈部载荷显著降低。

Abstract：To reduce the damage of whiplash injury in low speed rear-end collision， an optimization method of seat back modeling surface is proposed and its influencing mechanism on headback clearance is discussed. Based on the method， the whiplash performance of a certain seat is optimized and verified through experiments according to CNCAP procedure. The results show that the proposed method has less influence on seat modeling， the optimization objective is in good agreement with the experiment results， and the injury value of dummy neck decreases by 16.6%，a significant reduction for both upper neck load and lower neck load.
