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.
