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 rib for a crash test dummy includes a metal band, a plurality of layers of damping material disposed on a portion of the metal band, and a cover coupled to the layers.

A mobile fixture configured to move a structure in a manufacturing environment may include a motorized base configured to move on a surface and a support system connected to the motorized base, the support system being configured to support the structure, the support system being configured to position the structure along at least one of an X-axis, a Y-axis, and a Z-axis, the support system being configured to position the structure about the Z-axis, and the support system being configured to provide free rotation of the structure about at least one of the X-axis and the Y-axis.

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.

The present invention relates to a system for determining the position of movable dummy elements in a roofed test site, in particular in a hall. The system comprises a camera configured to record an image of a monitoring area of the roofed test site, a movable dummy element which is movable through the monitoring area, the dummy element comprising a marker element arranged to be visible on the recorded image of the monitoring area, and a position determination unit coupled to the camera and configured to determine the position of the marker element in the monitoring area based on the recorded image.

A sensing device for actuating an airbag system in a motor vehicle comprises an airbag having a stowed condition and an inflated condition, an inflator operationally coupled with the airbag responsive to electrical actuation for inflating the airbag with a gas, an impact detection sensor for generating a signal upon an offset impact event, and a controller for processing the signal generated by the sensor and electrically actuating the inflator upon computing a predetermined impact severity to a forward corner of the motor vehicle. The motor vehicle further comprises a front bumper beam attached proximate a distal end of a front rail and the sensor comprises a flexible electro-resistive sensor mounted to a rear side of an outboard portion of the front bumper beam.

Provided is a hybrid servo actuator for a crash test, and more particularly, a hybrid servo actuator for a crash test in which an operating part including a piston and a rod, a chamber supplying an air pressure to the operating part, and a controller controlling a movement of the operating part are integrally formed, thereby increasing a moving speed in a stroke direction of the operating part more than in a general hydraulic cylinder and pneumatic cylinder. The actuator includes an oil pressure cushion type cushion part provided therein to absorb a shock generated by a shock of an operating part even at the time of a malfunction of the operating part and discharge an oil pressure generated by the shock to the outside and thus is used semi-permanently.

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.
