摘要
基于碰撞能量守恒原理,将正面碰撞波形简化成参数化两阶梯形等效波形,借助正交试验设计方法和多目标优化设计平台(modeFRONTIER),研究了这些特征参数对乘员胸部损伤的影响.优化结果表明:运用多目标遗传算法(NSGA-II)优化出合理的正面碰撞波形,提高了乘员胸部的保护效果.
Based on the law of energy conservation,the crash pulse was simplified into a two-phase parametric trapezoid equivalent pulse.The effects of these parameters on occupant chest injury were studied by using the orthogonal experimental design method and modeFRONTIER.The optimization result shows that the reasonable crash pulse can be obtained by multi-objective genetic algorithm NSGAII to improve occupant chest protection.
