Simulation and Analysis of Relief Valve with F-pi Bridge Pilot Circuit Based on AMESim

摘要

Analyzes the working principle of the relief valve with F-π bridge pilot hydraulic resistances network, and uses the HCD database of AMESim to make modeling, and analyses influence of steady-state characteristics under hydraulic resistances parameter, obtained 3 different pressure flow curve, shows that the deviation in the steady-state voltage regulator for positive or zero, F-π bridge relief valve has good dynamic characteristics.
