| Abstract: | Aiming at the design requirements of shield tunnelling machine for simulator test rig, hydraulic systems of shield were designed and manufactured by applying electro-hydraulic proportional control technology, which included thrust hydraulic system, screw conveyor hydraulic system and cutting wheel drive hydraulic system. Experimental analyses were also carried out. The experimental results showed that the designed hydraulic systems could meet the tunnelling requirements of shield at all kinds of geological conditions. The front earth pressure value could also be controlled in the range of set value by adjusting the advancing speed, screw conveyor revolving speed and cutting wheel revolving speed, which lead to reduce ground deformation. |
