摘要
在L车型开发过程中,用ES-2型假人分别进行了FMVSS214和E-NCAP侧面撞柱试验。FMVSS214试验柱壁障从车辆碰撞侧偏前位置斜向侵入,E-NCAP试验柱壁障从碰撞侧垂直侵入。两种柱壁障侵入方式最终造成FMVSS214中假人向碰撞侧倾斜不明显,上半身受力时序依次为身体的上、中、下,且试验中座椅侧翼阻尼作用小,侧面安全气囊腹部位置易发生触底;E-NCAP中假人上半身有明显向碰撞侧倾斜现象,上半身受力时间比较接近,且座椅侧翼起到一定保护作用。试验结果表明,与现在执行的E-NCAP相比,在用ES-2型假人碰撞下,FMVSS214试验中假人胸部伤害相对偏小,腹部伤害相对偏大;在2015版E-NCAP侧面撞柱试验调整方案实施时,约束系统开发需要提高对腹部的保护作用。
With ES-2 dummies, two kinds of rigid pole side impact tests,according to the FMVSS214 and E-NCAP, were completed in the L model development process. The rigid pole will intrude obliquely into the vehicle impact-side from the front end in the FMVSS214 test, and the rigid pole will vertically intrude into the vehicle from the impact-side in the other test. The two kinds of intrusion modes eventually lead to tje following results. For the FMVSS214 test, the dummy doesn＇t show clear inclination towards the impactside.The upper, middle and lower part of the upper-body was successively subjected to the force. The seat contributes with a weak damping effect and the side air bag is easy to bottom out in the abdomen. For the E-NCAP test, the dummy shows clear inclination towards the impact-side. Every part in the upper-body is subjected to the force at almost the same time and the seat plays a protective role. The comparison shows that the dummy has minor chest injury and more severe abdomen injury for the FMVSS214 rigid pole side impact test by using the ES-2 dummies.Therefore the development of restraint systems needs to improve the abdomen protection when the adjustment program of the 2015 E-NCAP rigid pole side impact test is carried out.
