A collision simulation test apparatus including a table to which a test piece is to be attached, the table being movable in a predetermined direction, a toothed belt for transmitting power to drive the table, a drive module capable of driving the toothed belt, and a control part capable of controlling the drive module. The control part is capable of controlling the drive module to generate an impact to be applied to the test piece, and the impact generated by the drive module is transmitted to the table by the toothed belt.

A Dynamic Motion Element (DME) is disclosed that includes a platform, and a pair of foot movement mechanisms. The foot movement mechanisms each include a drive pulley connected to at least one wheel of the DME, a second pulley and a foot drive belt that has a foot connection structure constructed to detachably connect to the foot of the mannequin. The foot connection structure is constructed to move about each pulley. The first and second foot movement mechanisms are constructed such that when the DME moves in a longitudinal direction relative to the ground, the foot connection structure of the first foot movement mechanism remains in substantially the same longitudinal position relative to the ground while the foot connection structure of the second foot movement mechanism moves in the same longitudinal direction as the DME. When a mannequin is connected to the foot connection structures, the DME produces a more natural looking gait.

The road simulation device includes a frame structure and a transmission structure. The transmission structure includes a first test bench, a second test bench, a third test bench and a fourth test bench. A first sliding plate structure of the first test bench slides in a first direction and a second direction, a second sliding plate structure of the second test bench slides in the first direction, and a third sliding plate structure of the third test bench slides in the second direction. The first sliding plate structure and the first base structure, the second sliding plate structure and the second base structure, the third sliding plate structure and the third base structure, as well as the fourth baffle plate structure and the fourth base structure are connected by spherical hinges. Damages to the frame structure caused by huge acting force generated by rigid connection during testing can be avoided.

A vehicle inspection apparatus includes: an exciter roller (3) configured to apply vibration to a vehicle (6); a control device 5 configured to control the exciter roller (3); and a vibration setting unit (the control device (5)) configured to set a vibration that is input to a wheel (7) of the vehicle (6) when abnormal noise generated in the vehicle (6) is detected. The control device (5) provides a range of vibrations including the vibration set by the vibration setting unit and applies the range of vibrations to the vehicle (6).

The present invention discloses a method of filling simulated muscles for a limb of an automobile crash test dummy, the simulated muscles are molded with foaming in the inner cavity of the mold; the method comprises: obtaining a filling volume of the inner cavity of the mold by using a liquid casting method, preparing an adhesive liquid film layer, preparing a filler and conducting demolding detection on the limb. Wherein step 3 is to inject the mixed filler into the inner cavity of the mold so as to be foamed in the mold to form foamed sponge, and stand until the foamed sponge is foamed to the exhaust port and does not overflow any more.

A soft collision target, in particular for use within the framework of non-destructive collision tests, has an illumination device that comprises at least one illuminant and a covering structure, wherein the covering structure surrounds the illuminant and is configured to absorb forces acting on the illumination device on a collision and/or to conduct them at least partly past the illuminant.

A crash barrier for implementing a collision with a vehicle has a front to be moved toward the vehicle when the collision is implemented. The front side has a predetermined width and a predetermined height. The front side further has a selected surface region that takes up at most a 50% part of a width of the front side. A volume region of the crash barrier behind the surface region has a greater level of rigidity than a surrounding region of the crash barrier. Therefore, in the event of an impact against the vehicle, a greater level of rigidity acts in the selected surface region than in a surrounding region.

A fixture includes a vehicle body and a tube connected to the vehicle body. The tube has an axis, and the fixture includes a piston slideably disposed in the tube along the axis. A seat belt D-ring is mounted to the piston. The tube and the piston each define holes positioned to be aligned with each other when the piston is in multiple positions along the axis in the tube. A pin is engageable with the holes when the holes are aligned.

A three-dimensional printed component of a crash test dummy includes at least one material and the at least one material being printed by three-dimensional printing from a CAD model to form the three-dimensional printed component for different performance requirements for the crash test dummy.

The present disclosure provides systems and methods to test an autonomous vehicle. In particular, the systems and methods of the present disclosure can receive, from one or more test nodes of a preconfigured test track, log data indicating positions of elements of the test track over a period of time. Log data indicating parameters of an autonomous vehicle over the period of time can be received from the autonomous vehicle. The log data indicating the positions of the elements of the test track over the period of time can be compared with the log data indicating the parameters of the autonomous vehicle over the period of time to determine a performance metric of the autonomous vehicle on the test track over the period of time.
