【摘要】 通过数值模拟方法对某一真实车-自行车碰撞事故案例建立车辆及人员的数值模型,人体损伤仿真结果与法医勘验结果吻合,验证了该模型的可靠性.以该模型为基础,对不同速度及不同撞击位置情况下的车-自行车碰撞虚拟试验进行计算,探讨了不同情况下人体抛距、头部最大加速度及小腿最大受力等信息的规律性.数值模拟技术与法医勘验工作相结合将为交通事故鉴定提供科学的理论依据和数值参考.更多还原

【Abstract】 Numerical simulation of a real car-bike collisions was done by establishing the vehicle and rider model.The bodily injury simulation results coincide with the results of forensic confessions,which validates the reliability of the numerical models.Based on the model,for different impact on different speed and the position of the car-bicycle collision a virtual test was calculated,which explores the law and other information of the human body under different circumstances from the dumping,the greatest acceleration of head and legs maximum force.The numerical simulation technology combined with the forensic work will provide traffic accident identification with scientific theory and numerical information.更多还原
