Analysis of Damage Effects of Drivers' Emergency Stance in Frontal Impact of Vehicle

In order to study the influence of driver's emergency posture on the damage during the car 100% frontal collision, MADYMO simulation model of "vehicle cockpit-driver-restraint system" was established according to the actual vehicle crash test data, and the validity was verified. Using the established simulation model, positioning the dummy and adjusting the parameters, a 100% frontal collision with a speed of 64km / h was carried out. Collision simulation was carried out for four kinds of typical emergency posture of the driver in the event of a collision, and then the driver's head, chest acceleration and damage value were compared. The results show that under several typical emergency situations, when the driver is in the retracted position, the head of the driver will make direct contact with the steering wheel, resulting in serious injury; while the chest is restrained by the seat belt with little difference in damage.However, when the driver of the collision maintains the normal sitting posture, the driver has the least damage, and the restraint system can achieve the best protection effect at this time.
