In the process of tunneling of tunnel boring machine (TBM), different geological conditions often correspond to different working conditions, and the randomness of geological conditions also causes the order of occurrence of each working condition to be different. Under the conversion of different working conditions, this makes the vibration of different types of cutterheads different. How to choose the appropriate type of cutterhead according to different geological conditions is very important for saving engineering cost and increasing cutterhead life. In view of the above situation, this paper proposes a stability evaluation method during the TBM tunneling process to select the appropriate cutterhead type. Firstly, the corresponding relationship between geology and working conditions is established according to different geological conditions, and the input loads corresponding to geological conditions are obtained. Then, it is substituted into the dynamic model of the cutterhead system, the vibration response boundaries of each degree of freedom are obtained by solving. And the average value of the maximum boundary amplitude of each degree of freedom is taken to represent the extreme vibration of the cutterhead under the corresponding working conditions. Finally, by comparing the fluctuation of the ultimate vibration amplitude of each type of cutterhead in the process of working condition conversion, the results are as follows: when the transition between homogeneous strata and composite strata is normal and there is no large turning and deviation correction, the vibration response of the two-part cutterhead is the smallest, and the two-part cutterhead is the best choice. Otherwise, the five-part cutterhead is the best choice, while the stability of the integrated cutterhead is the worst.

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,
