Research Of The Tunnel Boring Machine Thrust System

TBM (Tunnel Boring Machine) is an advanced construct technology with the development of city densification, traffic, aqueduct, electric control and communication equipment, which integrates machinery, electric, hydraulic, measure and control technology. This technology has become the study focus in engineering field in the world with the rapid development of city constructions. Studying TBM technology has far-reachingmeaningtopromote equipment manufacturing level, to enhance our independence innovation capacity.This paper depicted a survey of that history of Tunnel Boring Machine, and domestic, international current status and it development trend, elucidated the meaning of its development in our nation.This paper is based on the TianShan Mountain TBM Tunnel Boring Machine reconstruction project as the background, Thesis is divided into two parts:First of all paper based on analysis of the tunnel boring machine TBM composition and the tunnel process on construction, According the actual project requirements of Transformation requirements. To program design for TBM Tunnel Boring Machine. The program includes system hardware structure design and selection and Control program preparation. The preparation of the control procedures, this paper introduces the TBM Systems and TBM cutter head drive propulsion system thrust automatic control and torque control of these two areas. Second Analysis system, and to make torque, thrust structure control of the double-loop control system. Third, the paper combines the propulsion system works on the propulsion system for modeling, and using MATLAB language programming and SIMULINK simulation of a combination of methods. For a given step signal, respectively the torque and thrust control of pairs of closed-loop PID,Fuzzy PID control and neural network PID Control Simulation. The simulation results can be better control of the program.
