DEVICE FOR ACTIVE VIBRATION SUPPRESSION Russian patent published in 2016 - IPC G10K11/178 

FIELD: machine building.

SUBSTANCE: device contains sensors of rotation period of mechanism shafts, equal number of the compensation sources and control receivers, installed on foundation, electronic circuit of suppression system, comprising analyser, discrete integrator, synthesizer, generator of exponent functions, period meter. Outputs of the sensors of rotation period of mechanism shafts are connected with inputs of the generator of exponent functions and inputs of the period meter. Outputs of the control receivers are connected with the analyser inputs, and output of the period meter is connected with the second input of the analyser. The output of the generator of exponent functions is connected with the third input of the analyser and first input of the synthesizer. The device has modal synthesizer, at that output of the analyser is connected in series with input of the modal analyser, discrete integrator, modal synthesizer and second input of the synthesizer, its outputs are connected with inputs of the compensating sources.

EFFECT: increased efficiency of vibrations suppression.
