| Abstract: | As the research object,three-dimensional model of the electric-hydraulic control valve which is used on hydraulic support was established.The method of CFD was used to the simulation of fluid three-dimensional velocity field and pressure field.The fluid velocity vector,pressure and turbulent Kinetic energy distribution graphs were obtained.They reveal the flow field law in the main spool.The simulation result provides the basis for the later optimization design. |
