简单介绍了TBM刀盘脱困装置的基本结构和工作原理，重点阐述了脱困装置的重要设备---液体黏性离合器的关键参数对TBM刀盘脱困过程的影响，并通过仿真对脱困过程中脱困扭矩与转速的关系、扭矩与液体黏性离合器的油膜厚度、油膜厚度与控制压力的关系进行了分析。结果表明，所选择的TBM刀盘脱困驱动装置能大幅提高刀盘的输出扭矩，通过控制油缸活塞的位移实现对液体黏性离合器油膜厚度的控制，从而控制刀盘输出扭矩的范围，并能有效防止摩擦片直接接触造成摩擦片的破坏。

The basic structure and working principle of Tunnel Boring Machine (TBM)cutter-head breakout driver system were introduced. The influences of the key parameters of the hydro-viscous speed clutch,an important device of TBM cutter-head driver on the breakout process,were expounded. Through simulation,the relationship between the breakout torque and speed,torque and oil film thickness of hydro-viscous speed clutch,oil film thickness and control pressure during the breakout process were analyzed. The re-sults indicate that the TBM breakout driving device can improve the output torque of the cutter-head greatly. The oil film thickness of the hydro-viscous speed clutch can be adjusted by control the displacement of the cylinder. Therefore,the range of output torque of the cutter-head driver system can be regulated accordingly. Additionally,the damage caused by the direct contact of the friction plates of the hydro-viscous speed clutch can be avoided effectively.
