摘要： The invention relates to a method for operating a test device (100) and to a test device (100) for simulating motor vehicle crashes, wherein the test device (100) has a carriage arrangement (110) which is arranged so as to be displaceable along a rail arrangement; a test setup which is arranged on the carriage arrangement (110) and has at least one motor vehicle component to be tested; and an acceleration unit (120) by means of which a force can be transmitted to the carriage arrangement (110) in order to accelerate the carriage arrangement (110). The acceleration unit (120) has a hydraulic drive cylinder (122) with a piston (123) and a piston rod (121) which is connected to the carriage arrangement (110). In order to ensure that a simulation of accident situations can be improved in a way which is easy to implement but nevertheless reproducible, according to the invention, at least one measuring pickup (126, 127) is provided for sensing a pressure (P1, P2) which acts in the piston-side region (128) and/or in the piston-rod-side region (129) of the drive cylinder (122), and further that a control device (150) is provided which is configured to set a quantity of hydraulic fluid which is fed into the piston-side region (128) of the drive cylinder (122), per time unit, as a function of the pressure sensed in the drive cylinder (122), and/or which is fed into the piston-rod-side region (129) of the drive cylinder (122), or discharged therefrom, per time unit, as a function of the pressure sensed in the drive cylinder (122), in such a way that an acceleration force which is transmitted to the carriage arrangement (110) assumes a value which is defined or can be defined in advance.
