SHOCK ACCELERATION PICKUP Russian patent published in 2001 - IPC

FIELD: instrumentation. SUBSTANCE: device is designed for metering threshold value of chock acceleration. Invention provides measurement of shock accelerations acting onto object in all directions at short-time amplitudes. Pickup has first conical seat with ball secured in housing, lever secured in housing for turning relative to its center, second conical seat with second ball, two permanent magnets with pole pieces. Balls are placed on lever at different sides from center of rotation. One end of lever is arranged between first magnet and its pole piece, and other end, between second magnet and pole piece. Lever is made, at least on its ends, of magnetically soft material. Angle of cone of conical seats is within 60 and 75 deg. EFFECT: provision of measuring shock accelerations acting onto object in any directions. 4 dwg
