【Abstract】 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 results 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.更多还原
