The arm provided in this embodiment has an active function.

According to one embodiment, a structure evaluation system includes at least three or more sensors, a position locator, and an evaluator. The three or more sensors are arranged on surfaces different from a surface to which an impact is applied with respect to a structure at different intervals in a first direction of the structure and a second direction orthogonal to the first direction and detects elastic waves generated from the structure. The position locator locates a position of a source in which the elastic waves are generated on the basis of the elastic waves detected by each of the three or more sensors. The evaluator evaluates a deterioration state of the structure on the basis of information based on a position location process of the position locator and information indicating a position where the impact is applied.

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.
