Abstract
In TBM tunneling process, the excessive vibration often leads to serious damage in some of TBM main components. Appropriate tunneling parameters such as cutterhead rotation speed, advancing speed, etc have a significant influence on TBM vibration. This study is based on a TBM muti-degree of freedom nonlinear dynamic model. The total force in three direction and torque on cutterhead are calculated according to the real data. The subsequent calculation shows that keeping the rotation speed in the range of 5.88–6.2 rpm can make the cutterhead vibration at a low level. And the effect of different TBM advancing speed is analyzed under this appropriate rotation speed. It shows that there is no significant change in the axial and vertical vibration condition of cutterhead and main frame with the advancing speed changing from 2–3.2 m/h but the horizontal vibration obviously increases. The deviation analysis of TBM motor’s input torque is also carried out. The vibration situation of each pinion is analyzed which determines No 7,8,9 pinions are particularly affected.
