| Summary: | In this paper, based on the servo valve controlled pressure cylinder, a scheme of hydraulic pipeline adjustable parameters water hammer wave test system is proposed. By changing the quality of pressure cylinder piston rod and controlling the opening of servo valve, the overshoot, pressure rise rate and oscillation of water hammer wave can be controlled. On this basis, based on AMESim simulation software, the paper studies the influence of different parameters of pressure cylinder and servo valve on water hammer wave, which provides the basis for the selection of main components. Finally, the experimental research is carried out on the designed system, and the results are consistent with the simulation results. The generated water hammer wave meets the requirements of the test standard, which proves that the hydraulic adjustable parameters water hammer test system developed in this paper is successful and feasible.
