摘　　要：对以G型π桥液阻网络为先导控制回路的溢流阀稳定性进行了理论分析 ,指出G型π桥溢流阀稳定性与先导回路液阻参数、先导阀的受压面积及弹簧刚度有关 .根据劳斯稳定判据 ,建立了G型π桥溢流阀稳定的判定条件 .通过试验研究 ,说明本文的理论分析结果与试验结果有较好的一致性 ,其研究成果为G型π桥溢流阀的动态设计提供了理论根据 .图 3 ,参 7.The stability of relief valve with G-π bridge pilot hydraulic resistances network was analyzed theoretically. It showed that the stability of G-π relief valve is determined by pilot hydraulic resistance parameters, left and right areas of the pilot valve and pilot spring stiffness. In terms of Routh stability criterion, deduced the stable criterion rule of G-π bridge relief valve. The experiment indicated that theoretical value was in good agreement with the experiment result. As a result, theoretical formulas for dynamic design of G-π bridge relief valve was proposed.
