FIELD: testing equipment.
SUBSTANCE: invention relates to the testing equipment, in particular to the test benches for the articles testing for vibration and shock impacts. Device comprises foundation, on which the shock pulse generation device is arranged, tray mounted on the rammer with possibility of movement and impacting with the shock pulse generation device. In addition, a device is introduced, consisting of base and cover, on which the tested object is installed, interconnected by fastening elements from the cover upper end side. At that, between each fastening element and the cover upper end at least one resilient element is installed for the cover to the base pressing, which is rigidly connected to the tray by means of fasteners.
EFFECT: technical result consists in provision the possibility of the positive polarity multiple sinusoidal shock pulse (without transition to the shock acceleration negative region) reproduction on the tested object, of the same amplitude and duration during the device one loading (one experiment) with given parameters with the device loadings on the impact test bench.
