Abstract
An object of the present invention is to provide a collision performance evaluation test method and apparatus that achieve a part collision test that satisfactorily reproduces the state of an actual automobile body collision, allow the test to be performed in a high-speed region, and increase the economic rationality of the test. A motion control mechanism formed of a translation control mechanism or a rotation control mechanism is provided in at least one of a support jig that supports one end portion of an automobile body part and a support jig that supports the other end portion of the automobile body part. The motion control mechanism includes a fixed member fixed to a motion restriction member in the support jig and a movable member so connected to the fixed member as to be movable and fixed to the one end portion or the other end portion of the automobile body part. A compression member protruding from one of the fixed member and the movable member toward the other is fit into a guide portion formed in the other one of the fixed member and the movable member so as to extend in the movable direction of the movable member and disposed with an energy-absorbing member therein. The motion of the movable member with respect to the fixed member deforms the energy-absorbing member to apply reaction force in the direction opposite the direction of the motion to the movable member.
