Excessive vibration and vibration damage are serious engineering problems in the TBM boring process. TBM dynamic characteristic analysis is essential to the anti-vibration design of the TBM mainsystem. This paper classifies the TBM thatmostly used in the practical engineering into TBM 1 and TBM 2, and comprehensively analyses the difference of cutter layout strategy, pinion layout strategy, shield support structure, etc between TBM 1 and TBM 2. A dynamic comparative analysis of TBM cutterhead was carried out based on a TBM dynamic model. The analysis results show that the cutterhead horizontal vibration of TBM 1 is around 0.3mm while that of TBM 2 is around 1.4mm.The vibration periodicity of TBM 2 significantly reduces. The influence of shield vertical support on the horizontal and vertical vibration of TBM 2 is analyzed. The results show that settinga vertical support at the bottom of the shield reduces the TBM cutterhead vibration by about 12%.
