  • Patent number: 8453489
    Abstract: The invention relates to a method for conducting crash tests in which an object, in particular a motor vehicle or part of a motor vehicle, is typically mounted on a test slide which is accelerated, the acceleration force being generated by means of a pressurized-gas reservoir and specifically applied to the acceleration object via a piston and a push rod, while for reducing the cycle times, the desired gas pressure in the pressurized-gas reservoir is generated by moving a piston, itself exposed to a hydraulic fluid, so as to apply pressure on the gas. The invention also relates to a correspondingly implemented system.
