变负载系统的液压节流调速技术

Control of Machine Feed Rates with Flow-Control Valves over a Wide Range of Resistance in Hydraulic Systems

论述了提高变负载节流调速回路速度刚度的方法，不仅揭示了传统调速阀、溢流节流阀和差压式变量泵构成的常用液压回路的共性。

The method is discussed that can be used to design the accurate control of the machine element feed rates against an unsteady resistance.A lot of hydraulic circuits are presented as examples,part of them can be constructed by the conventional compensated flow-control valves,and others are new.
