前言液压伺服系统的靜特性就是在稳定状态下,负载流量Q_L、负载压力P_L与滑阀节流窗口通油面积A之间的相互依赖关系。在实际使用中常以流量增益K_q或速度增益K_v、压力增益K_p、流量—压力增益K_c、靜不灵敏区e_f等来表示液压伺服系统的靜特性。本文就3-YZF-Ⅰ型仿形头配套的液压仿形铣床的阀控油缸系统的靜特性进行定性和定量 Preface The static characteristics of the hydraulic servo system is the steady state, the load flow Q_L, the load pressure P_L and the spool throttle window oil area A interdependence between. In practice, often with flow gain K_q or speed gain K_v, pressure gain K_p, flow - pressure gain K_c, static insensitive zone e_f, etc. to represent the static characteristics of the hydraulic servo system. This paper qualitative and quantitative analysis of the static characteristics of the valve-controlled cylinder system of the hydraulic profiling milling machine supporting the 3-YZF-Ⅰ profiling head
