FIELD: impact tests of instruments. SUBSTANCE: impact test facility having brake mechanism is provided with case with ferromagnetic filler 15 placed in a spaced relation and between core 11 joined with drive shaft and circular winding 10 mounted in case 9 on output shaft of worm gear 7. Drive shaft carries feedback speed and tested object position sensors whose signals arrive at electronic unit comparing displacement parameters to ensure desired accuracy of reproduction of operating conditions and shaping of desired parameters of facility platform displacement. EFFECT: enlarged functional capabilities, improved accuracy of impact load reproduction. 2 dwg
