Paper Title:
Study of Pressure Pulsations Attenuation in Hydraulic System
  Abstract

A pressure pulsations reactive attenuator for controlling hydraulic system was investigated through theoretical and experimental means. The attenuator consists of many “mass-spring-damp” lumped parameter vibration systems with different natural frequency. Through the fluid-structure coupled vibration, the fluid vibrations are converted into structure vibrations. And on this device, the filter attenuation model was established and the simulation results show that, changing the system flow pulse frequency (from 186 Hz to 225 Hz) near to the resonance frequency (236 Hz) of a certain lumped parameter vibration system, the attenuator has a good effect because of component resonance attenuating hydraulic pulsation energy. To verify the correctness of simulation results, the experiment is tested and the results are homology. It provides a new practical technique for hydraulic system vibration control.
