FIELD: test equipment.
SUBSTANCE: invention relates to testing equipment and can be used in experimental treatment of products under laboratory conditions. Method involves reproducing impact processes on electrically controlled vibrating tables, characterised by formation of control signal in form of time section pulse transition function, obtained by controlling initial phase and duration; above control essentially strobing said control signal, besides said control signal is performed with adjustment of level of constant component of specified signal.
EFFECT: technical result consists in possibility of playing back vibrating impact controlled within, providing for specified test mode.
