Method for Reduction of Pressure Ripples using the Parallel Pipeline in Fluid Pipeline

분지를 이용한 유압관로계의 압력맥동 저감 방안

The pressure ripples are inevitabilitily generated by a fluctuation of flow rate caused pump mechanism, which occur noises, vibrations, and affect a control performance in tluid pipeline. The method for reduction of pressure ripples has been normally used a accumulator which is installed near the pump generating the pressure ripples. This paper introduces the parallel pipeline as a method to reduce pressure ripples in tluid pipeline, and confirms the usefulness of it in reducing the pressure ripples as compared with the fluid pipeline with a accumulator using AMESim(Advanced Modeling Environment for Simulations) Software.
