| 摘 要： | 采用电液比例控制技术设计了一种基于压力流量复合控制的盾构推进液压系统。利用基于CC-Link现场总线的PLC控制实现了盾构推进液压系统速度和压力的协调控制,采用组态王软件开发的盾构推进液压监控系统实现了人机交互。推进液压系统在盾构模拟试验台上进行了实验分析,结果表明：所设计的推进电液控制系统能实时控制推进压力和推进速度,显著减少了速度压力调节的相互干涉,能较好地满足盾构在不同地质情况下推进控制的基本要求。

| Abstract: | A thrust hydraulic system of shield tunnelling machine with pressure and flow compound control was designed using electro--hydraulic proportional control technology. The coordinated control of the pressure and the speed for shield thrust hydraulic system was realized with PLC based on the CC--Link Profibus technique, and the man--machine interaction was also developed for the condition monitor of shield thrust hydraulic system with Kingview software. Experimental analysis of thrust system was also carried out on a simulator test rig. The experimental results show that the thrust pressure and the thrust speed can be controlled in real time, and the interference between pres- sure control and speed control can be reduced obviously, which can meet the tunnelling requirements in different kinds of geologies. |
