title: Determination of effective field of application of active methods of vibrations and noise suppression in hydraulic and pneumatic drives
abstract: It is analyzed the causes of noise and vibration in the hydraulic and pneumatic drives. It is determined that the main sources of noise and vibrations in such systems are pneumatic or hydraulic sources of energy, the connecting lines. The motor can be identified as a source of mechanical vibration motor. Frequency spectra arising in hydro pneumatic systems are determined. It is shown that in a large number of cases, the fundamental components of noise and vibrations are low frequency. The known
