Dynamic Simulation Research Based on AMESim Load-Sensing Pump

In this paper, based on the analysis of load-sensing principles, load-sensing pump mathematical model is derived, using the software AMESim to establish the physical model is intuitive, and conducts the simulation research, the dynamic operation curve. Research has shown that: load sensing valve spring stiffness, spool, spool diameter opening shape and quality response to dynamic load sensing pump will have a significant impact, which has a certain reference value for designing and using load sensing pump.
