摘要/Abstract

摘要： 针对传统液压阀控系统传动效率低的问题，提出了一种新型液压回路——多级压力源液压切换系统，给出了该新型液压系统的组成、工作原理、多级输出力的定义以及节能机理的实现，并进行了机理建模；以3个压力等级为例，设计了混合控制策略；搭建了多级压力源液压切换系统原理验证实验台。实验结果表明，多级压力源液压切换系统在位移跟随过程中，压力切换时存在位移和速度抖动；与传统液压位置控制系统相比，该液压系统具有显著的节能效果。

Abstract: For conventional valve-controlled servo control system in huge throttling loss, a multi-level pressure hydraulic switching system presented a possible solution to this challenge. Firstly, composition, working principles, definitions of multi-stage output forces and realization of energy-saving mechanism of this new hydraulic system were given, and the mathematical model were established. Secondly, taking a three-level pressure power supply for a displacement control system as example, a hybrid switching control strategy was designed. Finally, an experimental rig was established, and the control and energy saving characteristics of multi-level pressure hydraulic switching system were validated. The results prove that displacement and velocity jitter are existed during pressure switching, it has a significant energy saving effectiveness compared to the conventional hydraulic displacement control systems with the similar useful working energy.

Key words: hydraulic system, switching, displacement control, energy saving
