提高液压传动系统抗干扰能力设计方法的研究

Investigation in design method of improving antidisturbance ability for fluid power transmission system

本文用自动控制理论中的稳定性分析方法,对液压传动系统中因速度转换或负载变化引起的前冲、后座和爬行机理进行了分析和研究,指出普通节流调速系统存在的问题,提出新的抗干忧节流调速系统的设计方法.为液压传动系统的抗干忧设计和应用提供了理论依据。

This paper makes analysis and research on mechanism of stroke foward, backlash and stick-slip resulting from speed transfer or load change in fluid power transmission systems with analysis method of stability in automatic control theory, points out the problems existed in ordinary flow-restricted speed regulating systems, puts foward the design method of new anti-disturbance system, and provides the theoretical basis for anti-disturbance design and application in fluid power transmission systems.
