Abstract
Shield tunneling machine is a kind of large-scale high-tech construction equipment specialized for the underground tunneling. Traditional shield tunneling machine with the circular-section has problems such as low utilization ratio of cross-section, waste of space and so on. In this paper, we present a new mechanism of the special-shape cross-section shield cutting mechanism, which can reduce the excavation area, reduce the amount of backfill soil, thus improving the efficiency and space utilization. We establish the calculation model of a section of cutting mechanism and analysis the motion requirements of the special section shield cutting mechanism, design the electro-hydraulic proportional control system. We establish the mathematical model of asymmetric hydraulic cylinder controlled by asymmetric proportional directional valve, obtain the transfer function of the electro-hydraulic proportional position control system of the cutting mechanism, and the simulating model of the hydraulic is built based on MATLAB/Simulink. The application of PID in control system can effectively solve the instable problem of system, obtain better system response and provide a theoretical basis for later analysis.
