Abstract: In allusion to the pressure compensation valve of LUDV multiway valve,what a key role it played in the system and established its simulation model in AMESim was described.The model was proved to be accurate by simulation and experimental results.The results show that it would weaken the hydraulic shock by addding a small stiffness spring to the LS chamber of the pressure compensation valve, and by appropriately increasing the diameter of the orifice in the pressure compensation valve would not affect the valve’s response speed either reduced hydraulic shock.
Key words: LUDV;pressure compensator valve;AMESim;simulation
