Abstract

Abstract: In order to deeply study the motion behavior of vehicles in the rear-end collision, a vehicle rear end collision accident model is established in the PC-Crash simulation environment. Considering with the relative velocity, offset, speed of the rear-end vehicle and wheel angle, the acceleration, yaw angle and yaw rate of the vehicle are obtained. The research results show that when the bias degree is 20%, the yaw angles of the rear-end vehicle and rear tracked vehicle is the biggest, and is easy to induce the secondary accidents such as rollover and fixtures crash. The larger the relative collision speed of the two vehicles is, the greater the acceleration and the shorter the duration of collision are. The research results can provide theoretical basis and data support for the driver's behavior decision-making, accident reconstruction and vehicle safety design.

Key words: rear-end collision, kinematic parameter, relative collision velocity, the bias angle, yaw angle
