IMPACT PULSE GENERATOR (VERSIONS) Russian patent published in 2024 - IPC G01M7/08 G01M17/00 

FIELD: testing.

SUBSTANCE: group of inventions relates to impact pulse generators for impact test benches for impact testing. Impact pulse generator comprises a cylindrical housing with a working chamber filled with working fluid, a piston tightly inserted into the cavity of the working chamber housing with possibility of movement along the chamber axis, a cylindrical support, a ring-shaped tray tightly and coaxially fixed on the external cylindrical surface of the support, and a ring-shaped cover which tightly closes the tray from above. Cylindrical housing is hermetically installed on the upper end of the cylindrical support. In the upper part of the cylindrical support there are evenly arranged radial holes connecting the inner cavity of the tray with the cavity of the cylindrical support. In the inner cavity of the cylindrical support there is a device for adjusting the gap between the cavity of the working chamber and the cavity in the tray, which is arranged in the form of a valve. Inside each vertical vessel there is a damper of working fluid velocity.

EFFECT: realization of impact pulses in relatively wide ranges of amplitudes and durations, as well as prevention of rejection of the test object after impact loading.
