Failure of cutterhead driving system (CDS) of tunnel boring machine (TBM) often occurs under shock and vibration conditions. To investigate the dynamic characteristics and reduce system vibration further, an electromechanical coupling model of CDS is established which includes the model of direct torque control (DTC) system for three-phase asynchronous motor and purely torsional dynamic model of multistage gear transmission system. The proposed DTC model can provide driving torque just as the practical inverter motor operates so that the influence of motor operating behavior will not be erroneously estimated. Moreover, nonlinear gear meshing factors, such as time-variant mesh stiffness and transmission error, are involved in the dynamic model. Based on the established nonlinear model of CDS, vibration modes can be classified into three types, that is, rigid motion mode, rotational vibration mode, and planet vibration mode. Moreover, dynamic responses under actual driving torque and idealized equivalent torque are compared, which reveals that the ripple of actual driving torque would aggravate vibration of gear transmission system. Influence index of torque ripple is proposed to show that vibration of system increases with torque ripple. This study provides useful guideline for antivibration design and motor control of CDS in TBM.

“…Cho et al 17 studied a gearbox for wind turbine and modeled the actual tooth contact between a pair of gears with spring elements, and the spring constants were determined through the stiffness analysis of gear teeth. Li et al 18 and Zhang et al 19 established a torsional model for the CDS of a shield tunnel boring machine, respectively, where the time-varying of the gear mesh was considered, but the vibration in the other directions were neglected. Wei et al 20 presented a dynamic model of multi-gear drive in TBM, considering the effects of inertia on the driving mechanism and cutterhead and the nonlinear coupling factors between the ring gear and multiple pinions.…”

The dynamic responses of the cutterhead driving system (CDS) of the tunneling boring machine with impact loads are investigated according to its typical structure in this paper. First, finite element model of CDS is proposed based on linear mesh stiffness hypothesis, in which the rotating components are introduced as beam elements with the same mass and stiffness characteristics, and the effects of cutterhead-rock stiffness and carrier stiffness of CDS are also taken into account. Then, the natural characteristics of the CDS and the corresponding energy distribution for the components are investigated using this model. Finally, numerical simulations are carried out to determine the dynamic responses under two different typical impacts, by means of transient trajectories in time-domain and amplitude-frequency spectra in frequency domain, respectively. With the dynamic behaviors analysis, the response frequency of the CDS and the corresponding components with the maximum load is shown at the end. This modeling approach should provide a new idea for the CDS dynamic designing.
