Abstract: A vibration reduction optimization method for host system of a tunnel boring machine to reduce the vibration of the host and prevent fatigue damage at the critical weak position of the TBM host system. Vibration reduction optimization of the TBM host system is achieved by using a damping alloy material to replace the cutterhead system's material and the connecting flange's material and adding a magnetorheological damper at the support system and the propulsion system. This prevents sudden incidents in the TBM host system and ensures that the TBM works safely and reliably.
