Abstract

As one of devices for passive safety, child restraint system remains a positive factor in securing the safety of child occupants in vehicles’ collisions. Generation of deceleration pulses is essential for dynamic tests conducted to assess the safety performance according to many regulations such as UN Regulation No. 44. It deserves research on how to generate the qualified pulses conveniently and with low cost. A new method of convenience using steel pipes or tubes is recommended after all the factors influencing the deceleration being ascertained. Varied combinations of parameters make it possible and easy to optimize the deceleration pulses.

基于仿真和实验验证的儿童约束系统动态试验中小车减速脉冲的产生
儿童约束系统作为被动安全装置之一,在车辆碰撞中仍然是确保儿童乘员安全的积极因素。减速脉冲的产生对于根据联合国第44号法规等许多法规进行的评估安全性能的动态测试至关重要。如何方便、低成本地产生合格的脉冲值得研究。在确定了影响减速度的所有因素后,推荐了一种使用钢管的新方法。不同的参数组合使得优化减速脉冲成为可能并且容易。
