Description
Summary:The absence of literature data on active reduction of the transmission of vibrations and pulsations of pressure through pipeline compensators with liquid is noted. A prototype of active broadband vibration damping system has been studied. The system is intended to determine the transmission of pressure pulsations through pipeline compensators with liquid. We present the results of active system testing with electromagnetic vibrator as a source of compensating force, a piezoceramic emitter as a source of compensating pressure pulsations, and a digital control device. Reducing the forces and pressure pulsations to 18 dB in the frequency band from 10 to 246 Hz has been obtained.
