Review and prospect of research on hydraulic pulsation attenuator

摘要

The pressure pulsation attenuator is able to decrease the fluid fluctuation of the hydraulic pump effectively, so it is widely used in construction machinery. This paper reviews the history and progresses of the research on the pressure pulsation attenuator in China and overseas,summarizes its two types: H-type rigid structure and built-in flexible material, meanwhile,discusses its future research area.
