This article considers the real condition, leads out the system's parameters' ( a&. Qm) best matching calculational formula which can make the power consumption least in the condition of the load curse and the proportional valve's no-load flow.
本文从实际出发,以负载曲线和比例阀空载流量为条件,导出以功耗最小为指标的系统参数:A(变量油缸活塞有效面积)与Q m(比例换向阀空载流量)最佳匹配计算公式。
