| Abstract: | In this paper, the model for thrust hydraulic system of shield tunneling machines was established and analyzed by simulated, lying on simply the thrust load of those machines. A scheme of pressure flow hybrid control was presented, simulated by AMEsim. The simulation findings proved that flow changes (waves or surges) caused of control pressure could be reduced and the control performance could be enhanced. Such kind of control scheme is significance to automatically control the shield tunneling machines. |
