Simulation Study of the Effect of Hydraulic Hose Parameters on Hydraulic Impact

Considering the large deformation of the hose pipe diameter caused by the pressure, this paper revises the hydraulic capacity on the basis of physical model of pipe-wall, establishes the mathematical model of the hose by lumped parameter model of pipe, builds the model of the system composed of the constant pressure oil source and flow valve using Simulink software and simulates the hydraulic impact by changing the pipe diameter and length. The established hose model and simulation results can provide reference for the related research.
