摘要
基于一例自行车与乘用车碰撞的交通事故,在MADYMO软件中建立仿真模型,并在此基础上研究碰撞车速、自行车曲柄长度和踏板相位对骑车人股骨损伤的影响.研究发现,车辆碰撞速度越大,骑车人股骨损伤越严重.曲柄长度和相位通过影响骑行人姿态影响股骨的损伤程度,曲柄越长、姿态越伸展,伤情越严重.
Abstract
Based on a traffic accident involving a bicycle and a passenger car,a simulation model is established in MADYMO,then the effects of collision speed,bicycle crank length,and pedal phase on femur injury of the cyclist are studied.It is found that the higher the collision speed of vehicle,the more severe the femur injury.The length and phase of the crank affect the injury to the both side femur by influencing the posture of the rider.The longer the crank and the more extended the posture,the more severe the femur injury.
