Electromechanical coupling dynamics of TBM main drive system

Tunnel boring machine (TBM) is seriously damaged due to excessive vibration, and its anti-vibration design is the key of the drive system design. At present, the coupling model between the gear load imbalance and the electronic control strategy is difficult to be established. The actual cutterhead vibration and the motor output torque law are unknown, which make the TBM system dynamical model different from the actual situation. The calculation...
