DEVICE FOR MEASUREMENT OF INSTANTANEOUS MECHANICAL VIBRATION POWER Russian patent published in 2002 - IPC

FIELD: vibroacoustic diagnostics; measurement of vibration power of various mechanical systems including those containing "weak" units in form of antifriction and sliding bearings provided with hydrodynamic lubrication. SUBSTANCE: device has several measuring channels according to number of preset directions of measurement. Each measuring channel includes vibrational acceleration sensor, preamplifier, integral and multiplier. Connected between output of preamplifier and second input of multiplier is scalar. Outputs of multipliers of all channels are connected to inputs of computer. According to another version, vibration rate sensor is used instead of vibrational acceleration sensor and differentiating member is used instead of integrator. EFFECT: reduction of measuring channels and sensors; enhanced reliability of measurements. 3 cl, 1 dwg
