Abstract
In order to clarifr the collision phenomenon of the traffic machine in motion, such as automobile and aircraft, it is necessary to examine not only the defonnation and the behavior of composed structural member but also the dynamic characteristic of friction coefficient and restitution coefficient in the collided contact surface. In this study, the restitution coefficient of 3 kinds of materials was measured using Air Gun. The velocity dependence of restitution coefficient was examined by carrying out the collision test at the different speed.
