The load-sensing system is established and the energy-saving principle of load-sensing system is introduced.Simulation model is established by using AMESim software.Load pressure changes are researched by simulation to analyze the impact on the output flow of pump when the system is in the state of constant flow and load-sensing valve spool area are researched by simulation to analyze the impact on the dynamic characteristics of the system.Simulation results show that when the system is in the state of constant flow,load pressure changes have no impact on the output flow of pump and load-sensing valve spool area has an important impact on stability of the system.
