It is essential to study pipelines＇ dynamic characteristic and their simulation method for the optimizing design and performance analysis. A simulated method was introduced to the pipelines＇ dynamic characteristic based on the idea of hydraulic pipelines＇ model of sectional lumped parameter with the dynamic friction and input ＆ output model of bond graph, The hydrodynamic shock test proves that the simulation method is suitable for pipelines＇ dynamic analysis. The model of pipelines and the simulation results can give useful information to improve the design of hydraulic manifold block and other pipeline nets.
