Abstract:
1. A device ( 1 ) for simulating crash scenarios, in particular for simulating the effects of a crash on a test object, comprising a sled ( 2 ), which is adapted to be accelerated in the longitudinal direction and which comprises a lower part ( 3 ) as well as an upper part ( 4 ) supported on the lower part ( 3 ) and used as a carrier for the test object, the lower part ( 3 ) and the upper part ( 4 ) having actuators ( 5 . 1 , 5 . 2 , 6 . 1 , 6 . 2 , 7 ) provided between them, by means of which pitching and yawing movements of the upper part ( 4 ) can be generated, wherein on an impact-side front end ( 8 ) of the sled ( 2 ), the upper part ( 4 ) is propped against the lower part ( 3 ) by means of a coupling rod ( 10 ) which is rotatably coupled on both sides thereof, at least five actuators ( 5 . 1 , 5 . 2 , 6 . 1 , 6 . 2 , 7 ) being provided between the lower part ( 3 ) and the upper part ( 4 ), and the upper part ( 4 ) being supported on the lower part ( 3 ) via the actuators ( 5 . 1 , 5 . 2 , 6 . 1 , 6 . 2 , 7 ) and the coupling rod ( 10 ) such that a rolling movement of the upper part ( 4 ) can additionally be generated by means of the actuators ( 5 . 1 , 5 . 2 , 6 . 1 , 6 . 2 , 7 ), wherein at least at a starting position of the sled the coupling rod extends substantially in a central longitudinal plane of the sled, the coupling rod being a rigid component able to absorb forces generated in the event of a simulated crash in the longitudinal direction of the sled such that the actuators need not absorb forces generated in the longitudinal direction.
