摘　　要：提出了以G型π桥液阻网络作为先导控制网络的数字式流量阀,分析了基于半桥和π桥液阻网络的数字式流量阀动态特性,应用SIMULINK软件对2种类型的流量阀动态特性进行了仿真。仿真结果说明,在先导控制系统压力产生波动时,基于π桥液阻网络的数字式流量阀的振动幅值只是基于半桥液阻网络的数字式流量阀振动幅值的3%。This paper offered the flow control valve with pilot G-π bridge hydraulic resistances. The dynamic model of the flow control valve with both half bridge and G-π bridge were analyzed. Numerical simulation of two kinds flow valves was studied with SIMULINK software. The response to step input pressure signal showed that the vibration magnitude of the flow valve with G-π bridge pilot circuit was only 3% of the flow valve with half bridge pilot circuit.
