液压动力机构由液压控制元件、执行机构和负载组成,对大多数液压控制系统来说,动力机构特性在很大程度上决定着整个系统的性能,是整个液压控制系统的基础,对于四通阀控制对称液压缸的研究,已有成熟的理论方法,但对阀控非对称液压缸不适用;基于负载敏感恒功率变量控制系统对四通阀控非对称液压缸进行数学建模并进行仿真分析。
Hydraulic power unit consists of hydraulic control components, actuators and loads, for most hydraulic control system, the power plant characteristics largely determine the performance of the entire system is the basis for the entire hydraulic control system for four-way valve There are mature theoretical methods to control symmetrical hydraulic cylinder, but it is not suitable for valve-controlled asymmetric hydraulic cylinder. Mathematical modeling and simulation analysis of four-way valve-controlled asymmetric hydraulic cylinder based on load-sensitive constant power variable control system .
