【摘要】 为克服弹性恢复系数人为选取对Ishikawa回弹模型再现事故的影响,考虑车辆变形这一重要参数,在Ishikawa回弹模型的基础上,增加能量守恒公式,建立新的碰撞动力学模型并再现一起实际事故,通过pc-crash进行验证表明:所建模型能很好地再现交通事故,且该模型不易受弹性恢复系数选取的影响,对弹性恢复系数的选取有指导意义。更多还原

【Abstract】 To overcome the effect of restitute coefficient selection on Ishikawa restitute model,considering vehicle deformation,energy conservation is added as constraint base on the Ishikawa restitute model. Then a new collision dynamic model is established to reconstruct a real accident. The results validated by PC-CRASH show that the proposed model could reconstruct the accident well and the proposed model is difficult to be effected by restitute coefficient selection. The model is significant to advice the restitute coefficient selection.更多还原
