| Abstract: | Based on state space method of modern control theory, the mathematical model for the two way/two position hydraulic operated directional valve in thread cartridge is established. The influence on the dynamic characteristics of the valve is analyzed with respect to the parameter varieties of the components with the simulation and 4 steps Runge-Kutta method is adopted with C~-~- procedure edited so as to obtain the optimum combination of the valve parameters. The effective means are provided for study of dynamic performance with the same class valves and it significantly improves the dynamic characteristics of valve. |
| Keywords: | Hydraulic operated directional valve State vector Dynamic characteristics Simulation |
