Device for the inverse simulation of accident scenarios

摘要

Device (1) for simulating the effects of an accident on a test object (2) by inverse simulation of an accident scenario, with an acceleratable carriage (3) as a support of the test object (2), and with an actuator (4) in the form of a hydraulic or pneumatic Cylinder for accelerating the carriage (3) in the longitudinal direction of the carriage (3), wherein the device (1) comprises a discharge path on which the carriage (3) expires or is decelerated after simulation, wherein a coupling device (5) is provided, coupling the carriage (3) to the actuator (4) such that during the simulation by the actuator (4) both positive and negative accelerations can be transmitted to the carriage (3), the coupling device (5) being arranged to to solve the coupling between the carriage (3) and actuator (4) after the simulation, so that the carriage (3) on the discharge path detached from the actuator (4) au is slammed or braked, characterized in that the coupling device (5) comprises an engagement element (10) which is connected to the carriage (3) or to the actuator (4), wherein the engagement element (10) in a guide (7) is guided, which is formed so that the engagement member (10) during the simulation with the respective other component in entnehmendem engagement, wherein the engaging engagement due to the guide (7) at a predetermined release position (12) of the carriage (3) dissolved becomes.
