STAND FOR TESTS ON HIGH-INTENSITY SHOCK EFFECTS OF DEVICES AND EQUIPMENT Russian patent published in 2017 - IPC G01M7/00 

FIELD: testing equipment.

SUBSTANCE: device consists of the hammer, the hammer suspension, the swiveling frame, the bed plate, the fixing device, the anvil for equipment mounting, the recording sensors. At the same time, the anvil is made in the form of the rectangular replaceable metal panel, rigidly fixed to the stand bed plate by means of the threaded rods, while the replaceable metal panel is made with recesses of rectangular shape and the ribs between the recesses. Moreover, all ribs are the same, and the distance from the metal panel edge to which the shock effect is applied, up to the recesses is at least 2 times larger, than the longitudinal size of the recess, but not less than 2 times smaller, than the distance up to the opposite relative to the shock effect place of the metal panel end. In this case, the natural frequencies of the ribs lateral vibrations do not coincide with the frequencies of the plate longitudinal vibrations before and after the recesses, and the rods axes, providing the fastening of the replaceable metal panel to the bed plate, passing through the recesses and do not coincide with the ribs, besides, the vibration gasket is installed between the replaceable metal panel and the bed plate.

EFFECT: accuracy and stability improvement of the shock effect playback, that is given by the acceleration spectrum.
