摘要：A device for attenuating the periodic vibrations of a mechanical structureadapted to obtain cancellation of periodic vibrations of rotating machines including atleast one transducer, detecting original vibrations, delivering a detected signal, adetector of the periodicity of these vibrations delivering a synchronizing signal, and acontrol circuit and a transducer generating compensation vibrations which are applied tothe mechanical structure. The control circuit includes a circuit for synchronous filtering ofthe detected signal, controlled by the synchronizing signal and delivering a filtered signalwhose frequency spectrum contains only the instaneous fundamental frequency of thedetected signal. A circuit for regulating the filtered signal delivers an antivibration-control signal applied to a generating transducer in order to minimize the amplitude ofthe detected signal.
