摘要：

为了深入了解侧碰远端乘员保护中不同性别乘员在碰撞过程中的响应差异，基于Euro NCAP 2020远端乘员保护试验及评价规程进行了某车型的侧碰滑台试验，并根据侧碰滑台试验中远端乘员的运动及其响应原理，对比分析了男性乘员（WorldSID 50th）和女性乘员（SID IIs 5th）运动姿态，伤害情况及响应时间的差异。结果表明：SID IIs 5th女性乘员下颈部弯矩最大值约为WorldSID 50th男性乘员的2.2倍, 女性乘员的腹部压缩变形量平均比男性乘员小约50%；女性乘员头部3 ms合成加速度和颈部弯矩响应时间均比男性乘员响应时间提前约12 ms。此研究为未来深入开发侧碰远端乘员保护方案提供有效的技术支持。

Abstract:

A side impact sled test of a certain vehicle model was carried out to gain an deeply understanding of the response differences of different occupant genders in the collision process of far side occupant protection based on Euro NCAP 2020 far side occupant protection test and evaluation procedures. Based on the movement and response principle of the occupants, the differences of the injury situation and response time between male (WorldSID 50th) and female (SID IIs 5th) occupants were compared and analyzed. The results show that the maximum bending moment of the lower neck of the SID IIs 5th female occupant is about 2.2 times that of the WorldSID 50th male occupant, and the average abdominal compression deformation of the female occupant is about 50% smaller than that of the male occupant; the 3 ms composite acceleration of the female occupant's head, and the response time of the neck bending moments are about 12 ms earlier than that of male occupants. This research provides effective technical support for the further development of the side impact far side occupant protection scheme in the future.
