摘　　要：非对称阀控制非对称缸常见于液压伺服系统中 ,其主要动态性能参数如流量增益、流量 -压力系数对该类系统的动态性能有重要的影响 .当使用非对称阀控制非对称液压缸时 ,阀的开度以及面积梯度的变化直接影响到流量增益和流量 -压力系数 ,为此 ,重点讨论了诸参数间的理论关系 。The unsymmetrical cylinder controlled by unsymmetrical valve is often used in hydraulic servo system.The dynamic performance of this system is deeply influenced by its main dynamic parameters,such as flow gain and flow-pressure coefficient,which are influenced directly by hatch sizes and aera grades of valve and provide the theoretical basis for choosing and designing such system.
