IMPACT VIBRATION TESTING DEVICE Russian patent published in 2020 - IPC G01M7/08 

FIELD: physics.

SUBSTANCE: invention relates to an impact vibration test device which generates repetitive impact actions on a test object. Proposed device comprises platform with surface to accommodate test object and support assembly located below said platform to make reciprocating movement and includes reciprocating structure and pressure changing component. Reciprocating structure is configured to move the platform between the first location and the second location. Pressure changing component is located next to the reciprocating structure and includes a cylinder or an airbag for creating pressure on the platform. Platform has area of contact pressure, and pressure changing component has positive pressure or negative pressure on area of contact pressure in area of contact pressure higher or lower from area of contact pressure.

EFFECT: technical result is possibility to adjust impact force by means of more convenient and simplified actions.
