The Application of Bond Graph in Researching Hydraulic Impact of Cylinder Controlled by Valve

The hydraulic impact is one of the common matter in the hydraulic system.It can cause the noise and vibration,damages the hydraulic part,even influences their life.So it disturbs the use of the system seriously.The basic conceptions about bond graph were introduced.Asymmetrical cylinder controlled by symmetrical valve was taken as example,the modeling of bond graphs of various hydraulic components and the method that solves hydraulic impact of the system was discussed,which validates the characteristic of the bond graph using in the analysis of hydraulic system tendency.
