Study on Modeling of Valve-Controlled Asymmetrical Cylinder Hydraulic System

Through considering the soft tube connection between valve and cylinder of valve-controlled asymmetrical cylinder hydraulic system,the system equations are constructed,and the two transfer functions on two directions-rod protruding and rod retracting respectively are derived,The gain and the natural frequency on two directions are also discussed.The SimHydraulics physical net simulation validate the analysis on transfer functions.
