汽车-自行车事故碰撞过程仿真

Analysis of Vehicle-to-bicyclist Collisions

为了更好的研究汽车与自行车碰撞的交通事故中的行人安全,基于多体系统动力学理论,使用动力学软件ADAMS建立了汽车—自行车碰撞模型。其中的人体模型已经应用PMHS轨迹运动数据进行了验证,并与一次假人碰撞试验进行了对比,结果吻合较好。应用建立的碰撞模型,模拟了不同汽车速度和不同自行车速度下的撞击过程,得到了一些有用的规律。从而为汽车被动安全的深入研究建立了一种快速、实用的工具。

In order to establish a systematic approach to the study on the injuries sustained by bicyclist in accidents, a computer simulation model of vehicle-to-bicyclist collision model was developed based on multi body kinematics and dynamics using Adams software. And the human model which used in this study was validated by PMHS trajectory tests and compared with one dummy collision test. The simulation indicates some useful results. And this vehicle–to-bicyclist model will be used as a useful tool for further sturdy of bicyclist safety.
