METHOD FOR CONTINUOUS RECORDING OF THE POSITION, PROFILE AND VELOCITY OF A STATIONARY SURFACE OF A PLATE SUBJECTED TO SHOCK-WAVE DEFORMATION Russian patent published in 2022 - IPC G01B7/16 G01L5/14 G01P3/42 G01P15/09 G01N33/22 

FIELD: physics.

SUBSTANCE: invention relates to the technology for recording and studying the space-time parameters of single fast processes (fast combustion of substances, explosion, high-speed interaction of materials, propagation of shock waves, etc.). Method for continuous recording of the position, profile and velocity of a stationary surface of a plate subjected to shock-wave deformation, consisting in using a system of waveguide piezoelectric sensors with reactive waveguides made on the basis of a non-Newtonian fluid, installed on the studied surface of the plate along a line perpendicular to the source of shock wave action, with rigidly clamped edges, and the position and velocity of high-speed action at any time of recording is determined by analysing the plastic deformation of the plate from the shock-wave action and a comparative analysis of the calibration graphs with the resulting oscillography patterns of the waveguide piezoelectric sensors.

EFFECT: expanded variety of geometry and shapes when recording the pressure wavefront of explosions and electrical discharges.
