Abstract Tunnel boring machine (TBM) operational data is mostly analysed with respect to that was recorded during the advance of TBM. Focusing on standstills a gripper TBM, we analyse rock loads were passively in cylinders small roof support shield. These are situated beneath TBM’s shield – extending it against mass non-advance periods. Equipped pressure sensors, they enable unique opportunity ...

Based on the damage evolution equation of bearing steel, a user subroutine was developed to simulate fatigue behavior TBM main under condition low speed and heavy load. In addition, law in time domain space studied. Then, nonlinear spring element introduced interaction between roller raceway, vibration response after studied using transient dynamic method. The research shows that risk raceway i...
