Numerical Simulation on Hydraulic Poppet Valve

Hydraulic poppet valves is the element components in hydraulic drive system,its performance will affect stability of the system.the mathematical model of poppet valve was established based on the finite element method, and the boundary conditions were described for study area. By the analysis of finite element, the rule of dynamic hydraulic pressure and velocity of flow,as well as the flow function when valve was in working,are obtained.It is the basis for studying the other characteristic parameter of poppet valve.
