“…Cutterhead design parameters and geology conditions such as the cutting depth, cutterhead opening ratio, excavation diameter, cutterhead forms, cutters amount and distribution, soil properties, rocks properties, boulders, and so on will directly affect load torque. In [19][20][21][22], the shield TBM cutterhead's load torque is estimated and calculated. Total load torque of cutterhead includes six parts, which are presented as follows [20]:…”

This paper establishes a general dynamic two-dimensional nonlinear time-varying (TDNLTV) vibration model with multi-drive shaft for shield tunnel boring machine (TBM) cutterhead driving system. Multipleinput and multiple-output (MIMO) state-space vibration model of cutterhead driving system is also presented. TDNLTV vibration model is simulated, and physical parameters' effects on the vibration response are detailed investigated. A preliminary approach is proposed to reduce vibration or nonlinear vibration behaviors. Dynamic TDNLTV vibration model provides a basic foundation of fault detection and diagnosis (FDD) and health monitoring for cutterhead driving system. i-th induction motor rotor viscous damped after equivalent coupling-i J z,i inertia of the i-th coupling between motor-i and reducer-i b z,i viscous damped of the i-th coupling between motor-i and reducer-i J r,ii -th induction motor rotor inertia b r,i i-th induction motor rotor viscous damped J m large gear inertia b m large gear viscous damped r m large gear radius θ p,i angular displacement of i-th active pinion θ i angular displacement of i-th motor rotor θ m large gear angular displacement ω m large gear angular speed J c,

“…A vertical vibration model was then established for the scrap- ing the cutter of the shield TBM, 19 and a nonlinear and linear kinematics model was established for the cutterhead driving system. [20][21][22] A two-dimensional, nonlinear vibration model of cutterhead driving system has been presented, 23 and the system performances of a hydraulic-driven cutterhead driving system was also studied. 24 This paper presents the LTVMA vibration model of cutterhead driving system.…”

In this paper, a general linear time-varying multiple-axis (LTVMA) vibration model of shield tunnel boring machine (TBM) cutterhead driving system is established. The corresponding multiple inputs and multiple outputs (MIMO) state-space model is also presented. The linear vibration model is analysed, and the vibration-torque transfer function matrix and the vibration-torque static gain matrix are obtained. The linear vibration model is simulated, and the physical parameters' effects on the vibration response are investigated. A preliminary approach is proposed to reduce vibration by increasing motor rotor inertia and viscous damped. The LTVMA vibration model provides a solid foundation for fault detection and diagnosis (FDD), as long as the health monitoring of cutterhead driving system.
