- Abstract
In the vehicle side impact test, the dummy injuries were caused by the door intrusion. But because of the complexity of the door structure and the connection relation between the door and the vehicle body, the acceleration of the different position of the door was greatly diverse in the side impact. In order to make the velocity of different part of vehicle door in side crash sled test correlate to their velocity during vehicle crash test, the side crash sled test was equipped with different stiffness and damping. So, a lumped-mass model of side vehicle impact was built According to the regulation of occupant protection of vehicle side impact (GB20071-2006). And the spring stiffness and damping of different parts of vehicle door corresponding to the dummy abdomen and pelvis was estimated by the recursive least square method based on test data. Through verification the simulation result got a better accordance with experimental data.
