双连杆偏心隧道掘进机的恒功率控制研究

Study on Constant Power Control of Tunneling Machine

液压缸驱动的双连杆偏心隧道掘进机较通常的圆形隧道掘进机具有独特的优点。它除了可以完成圆形断面的切削,还可以完成异形断面的切削。本文对其驱动液压缸进行分析,推导出恒流量供油时刀盘转速是脉动的。当泵采用恒功率控制时,可使刀盘转速脉动为零的结论。

A new TBM has particular virtues. This machine could cut particular shapes besides rotundity shape. Based on the analysis of hydraulic cylinder, the conclusion is as followed： The pulsation of cutter rotate speed is exists when the system is controlled by constant flux. The pulsation is nearly to zero when the system is controlled by constant power through variable pump..
