正面碰撞波形对乘员伤害值的影响

基于能量守恒原理,将复杂的实车碰撞波形简化成参数化的两阶等效波形。通过改变两阶等效波形中的特征参数,研究不同碰撞波形对乘员胸部加速度的影响。计算结果表明,通过合理控制碰撞波形和侵入量,可以有效降低乘员胸部加速度。

Effect of Frontal Crash Pulse on Occupant Injury Response

Based on the law of conservation of energy,the actual crash pulse from a real vehicle crash test is simplified into a two-phase equivalent pulse.By varying the characteristic parameters of the equivalent pulse,the effect of various crash pulses on occupant chest acceleration is studied by simulation using MADYMO.The results indicate that significant reduction in occupant chest acceleration can be achieved by controlling crash pulse and intrusion.
