摘要
针对V形TBM在小曲线转弯掘进过程中存在操作困难、掘进精度低等问题,文中对V形TBM主机结构机理及运动学进行研究.以某抽水蓄能电站排水通道工程为依托,首先通过建立V形TBM转弯调向模型,分析了影响V形TBM最小转弯半径大小的因素;其次,对φ3 530 mm的V形TBM主机进行改进设计,并基于蒙特卡洛法求解了两种推进系统下刀盘的可达工作空间;最后,通过ADAMS软件分析了 TBM在直线掘进工况和小曲线转弯掘进工况下,刀盘与推进油缸之间的位移和速度变化关系.研究结果表明:当TBM直径相同时,6-SPS推进系统刀盘中心点的工作空间小于8-SPS推进系统的;6-SPS推进系统在直线段的掘进效率更高;8-SPS推进系统更适合复杂多变的小曲线转弯工况掘进.
Abstract
In this article,efforts are made to explore the V-shaped TBM main engine's structure mechanism and kinematics due to difficult operation and low driving accuracy in the driving process of small curve turning.Based on the drainage channel project of a pumped storage power station,firstly,the factors affecting the V-shaped TBM's minimum turning radius is analyzed by setting up the V-shaped TBM's turning direction model.Secondly,the design of V-shaped TBM main engine with the diameter ofφ3 530 mm is improved;the cutter head's reachable workspace in two propulsion systems is solved with the help of the Monte Carlo method.Finally,the ADAMS software is used to analyze the displacement-velocity variation relationship between the cutter head and the propulsion cylinder in the straight driving condition and the small curve turning driving condition of TBM.The re-sults show that when the TBM diameters are the same,the workspace at the cutter head center of the 6-SPS propulsion system is smaller than that of the 8-SPS propulsion system.The 6-SPS propulsion system is more efficient in the straight driving section;the 8-SPS propulsion system is more suitable for complex and varied driving conditions with small curve turning.
