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.

A stone impact simulator is provided. That stone impact simulator includes a projectile propulsion section to propel a projectile toward a test sample and a projectile capture section to capture the projectile after the projectile ricochets off of the test sample. The projectile capture section includes a rebound block, a spent projectile storage compartment and a projectile energy dissipation element between the rebound block and the spent projectile storage compartment.

A test apparatus includes a linear motion generator, an airbag, a plate, a platform, an anthropomorphic test device, and a crushable member. The airbag is spaced from the linear motion generator. The plate is moveable by the linear motion generator toward the airbag, and the platform is fixed relative to the plate. The anthropomorphic test device is adjacent the airbag and includes an end coupled to the platform. The crushable member is disposed between the plate and the platform, and the crushable member is deformable by the plate. During operation of the test apparatus, the linear motion generator moves the plate into the crushable member to slow movement of the anthropomorphic device toward the airbag. The crushable member crushes to simulate the forces on the anthropomorphic test device from a vehicle side impact.

According to one embodiment, a structure evaluation system according to an embodiment includes a plurality of sensors, a position locator, and an evaluator. The plurality of sensors detect elastic waves. The position locator locates positions of elastic wave sources by using the elastic waves among the plurality of elastic waves respectively detected by the plurality of sensors having an amplitude exceeding a threshold value determined according to positions of the sources of the plurality of elastic waves and the positions of the plurality of disposed sensors. The evaluator evaluates a deteriorated state of the structure on the basis of results of the position locating of the elastic wave sources which is performed by the position locator.

A system for evaluating a bond includes a first electrode and a second electrode that are spaced apart from one another. The system also includes a sacrificial material layer positioned proximate to a surface of a bonded structure that includes the bond. The system also includes a power source configured to cause the first and second electrodes to generate an electrical arc that at least partially ablates the sacrificial material layer as part of a non-destructive inspection of the bond.

A test jig for an exterior door handle of a vehicle includes a first rotating shaft rotatably mounted on a vertical frame which is perpendicular to a horizontal frame that is supported on the ground. First plates are attached to both ends of the first rotating shaft to concurrently rotate with the first rotating shaft about a strike object by an elastic restoring force. A second rotating shaft is rotatably connected between the first plates. A second plate is attached to the second rotating shaft to concurrently rotate with the second rotating shaft about the strike object by the elastic restoring force when a handle is mounted.
