A Design and Computer Orthogonal Simulation for a Large Discharge Type of Hydraulic High Speed On-Off Valve

In order to achieve more output of large discharge and hydraulic pressure high speed on/off valve, optimize response course of valve loop electricity and displacement of ventileinheit, a new structure was designed. Adapting orthogonal experiment method, mass of core, damped coefficient of core in movement and spring stiffness in resetting of core were made as factors for research each of which contains four elements. By the tool of Matlab/Simulink, we can get sixteen simulation curves form which indicates that the three factors are key factors influenced the dynamic performance of valve. The result of simulation experiment shows when the mass of core "m = 0.08 kg", damped coefficient "c=16 kg/s" and spring stiffness "k = 1200 N/m", the valve can be steady in responsible course of displacement, and the on/off time less than 0.005 s. The flux of output can answer for need of design.
