为了研究EB骑行者与应急转向操作的SUV侧面碰撞事故中骑行者头部损伤影响,利用MADYMO软件建立SUV与EB/骑行者的事故碰撞模型,验证了模型的有效性,并在此基础上开展计算机仿真实验,对碰撞事故中不同SUV应急转向角、SUV车速、EB车速对骑行者头部损伤的影响展开研究.结果表明:SUV应急转向操作过度会导致SUV产生侧滑;无侧滑工况的SUV,骑行者头部HIC值随SUV应急转向角的扩大而降低;有侧滑工况的SUV,骑行者头部HIC值随SUV应急转向角的扩大而急剧升高;且侧滑工况随SUV车速的提高而变得愈加严重、引发侧滑所对应的SUV应急转向角也随之缩小;骑行者头部HIC值随SUV车速、EB车速的提高而升高;SUV应急转向操作过度会导致骑行者头部HIC值急剧升高,是非常危险的工况.
Research on the Effect of SUV Emergency Steering Operation on the Head Injury of Riders
To study the effects of head injuries on EB riders in a side impact with an emergency steering SUV,a MADYMO-based accident collision model between SUV and EB/rider was established to verify the validity of the model.Based on this,computer simulation experiments were carried out to study the effects of different SUV emergency steering angles,SUV speeds and EB speeds on head injury of riders in the collision accidents.The results show that excessive emergency steering operations of SUV can lead to sideslip of SUV.For SUVs without sideslip,the head injury criterion(HIC)value of the rider's head decreases with the expansion of the SUV emergency steering angle.For SUVs with sideslip conditions,the HIC value of the rider's head increases sharply with the expansion of the SUV emergency steering angle.Additionally,the sideslip condition gets worse with the increase of SUV speed,and the SUV emergency steering angle corresponding to the sideslip is also reduced.The rider's head HIC value increases with the increase of SUV speed and EB speed;The excessive operation of SUV emergency steering can lead to a sharp increase in the HIC value of the rider's head,making it a dangerous working condition.
