側面衝突を受けた車両の運動解析

（衝突位置の違いによる運動評価）

For more improvement of the collision safety, it is necessary that not only collision safety evaluation and measure at the primary collision, which is the accident between the vehicles at the first collision, but also collision safety evaluation at the secondary collision, which is another accident occurred by subsequence collision. However, collision experiment and safety measure, which is considered to secondary collision, are not sufficiently carried out, since the vehicle motion after the first collision is complicated and difficult to predict, although theoretical analysis has been reported. In this study, in order to evaluate the influence factors for collided vehicle motion after collision, we carried out the collision experiment at the difference of collision position with vehicle model, and compare the experimental results at the each collision position. As the results, the difference of collision position affects vehicle rotation and moving distance.
