| 摘 要： | 将汽车B柱加速度曲线反映的车体碰撞性能定义为车体"刚度",对车体"刚度"在实车碰撞中对假人伤害的传递过程及台车试验中复现的精度对假人伤害结果的影响进行了研究.通过对"刚度"在正面碰撞试验中对假人运动的影响分析和对骨盆受力情况的分析,指出了试验中假人对车体的相对加速度曲线是一近似正弦波.同时,进行了车体"刚度"曲线在台车试验中的应用研究,指出了在台车试验中应复现的最佳曲线及校核方法.

| Abstract: | In the paper, the vehicle crash performance reflected by the deceleration curve of B pillar is defined as vehicle rigidity, and the transfer process of injury to the dummy by vehicle rigidity during real vehicle crash as well as the effect of accuracy of injury reproduced by the sled test on dummy are investigated. It is pointed out through analysis of effect of rigidity on dummy movement during frontal impact test and pelvic stress analysis that the relative acceleration curve of the dummy relative to the ... |
