| Abstract: | The force status of the electro-hydraulic master valve was analyzed.Following the idea of studying the working principle after the structural analysis and then building the dynamic mathematical model and conducting the simulation,the paper built the mathematical model of the master valve,and then established a completed electro-hydraulic control system in AMESim according to the model.It also stressed the dynamic characteristics of the master valve as well as the opening order of two spools,and obtained the variation curve of displacement,flow and pressure of the master valve.The study showed that the steady hydrodynamic force was the key factor affecting the dynamic performance of the spool. |
