摘　　要：介绍了M4系列负载敏感比例多路阀的结构特点和工作原理,并在AMESim软件中建立该阀的相应模型,通过对其动态特性进行仿真可知,在单泵负载敏感比例多路阀液压系统中,当系统提供的流量充足时,多路阀的各负载联流量对负载的变化不敏感;当系统提供的流量不足时,多路阀的小负载联在负载变化时流量变化不大,大负载联在负载变化时流量变化较大。在采用双泵合流供油液压系统中,可在系统流量不足时双泵同时工作,避免因流量不足引起负载联的运动出现滞后及停止。通过仿真分析,深入了解M4系列负载敏感比例多路阀的动态特性,为其在液压系统设计及使用过程提供相关参考依据。所建立的模型为其他类型的负载敏感比例多路阀的模型建立、参数优化及设计开发提供了参考,具有一定的实用价值。The structure characteristics and working principle of M4 series load-sensing proportional multi-way valve are introduced mainly,and the corresponding model of the valve is set up in AMESim software.Through the simulation of its dynamic characteristics,it was known that in the hydraulic system of the single pump load-sensing multiplex valve,when the flow of the system was sufficient,the flow rate of various load joints of multi-way valve were not sensitive to the change of the load.When the flow of the system was insufficient,the flow rate of the small load joint of the multi-way valve varied little when the load changed,but the large load joint of the muliti-way valve varied greatly when the load changed.In the hydraulic system of the double pump load sensitive multiplex valve,double pumps could work simultaneously when the flow of the system was insufficient,avoiding the lag and stop of the movement of the load associated with the insufficient flow.Through the simulation analysis,the dynamic characteristics of the M4 series load-sensing proportional multi-way valve could be understood more deeply,and it could provide the relevant reference for the design and use of the hydraulic system.The AMESim model of M4 series load sensitive proportional multiplex valve has provided a certain reference and practical value for the model establishment,parameter optimization and design and development of other types of load sensitive proportional multiplex valves in the future.
