Development of Analyzing Method for Pressure Fluctuations in Oil Hydraulic Pipe Network Including Flexible Hose Element

유압 관로망에서 고압호스의 압력 맥동 감쇠 특성 해석법 개발

An analyzing method for pressure fluctuations in oil hydraulic pipe network was developed in this study. The object pipe network has multi-branch configuration, and the pipelines of it are composed of metal tubes and flexible hoses. Transfer matrix method, in other words impedance method, was used for the analysis. Values of physical parameters describing the characteristics of flexible hose were measured by experiments and reflected to the analysing procedure. The reliability and usefulness of the analyzing method were confirmed by investigating computed results and experimental results got in this study.
