Simulation Study of Dynamic Characteristics of High-Pressure Pulse Water Hammer
Abstract：Introduces the constructional principle of a new coal-seam injection device,high-pressure pulse water hammer,and carries out mechanical analysis.The simulation model of system is built based on Matlab/Simulink.Compared the simulation and experiment results,the feasibility of simulation is verified.The further simulation showes the stiffness of main spring changes from 2 250 kN/m to 1 000 kN/m,the steady pressure and the output peak pressure are increased.
