关于四通阀—不对称缸系统的理论及试验研究是现代液压伺服理论研究的课题之一。本文讨论了对称四通阀与不对称缸的不相容性,提出了解决不相容性的电路—面积补偿方法,给出了供系统数字仿真用的四通阀—不对称缸系统的动态方程。
Theoretical and experimental research on four-way valve-asymmetric cylinder system is one of the topics of modern hydraulic servo theory. In this paper, the incompatibility between symmetrical four-way valve and asymmetric cylinder is discussed, and the circuit-area compensation method to solve the incompatibility is proposed. The dynamic of the four-way valve-asymmetrical cylinder system for digital simulation is given equation.
