Study on Dynamic Performance of Cutter Head and Cutter System of Rock Tunneling Set-up

Abstract:

Several modals on Tunnel Boring Machine (TBM) in tunneling are introduced, the revolving rock tunneling simulator set-up is designed, the finite element model of cutter parts of the experimental bench is built, and free mode analysis of it is performed, and the model on system of cutter head, cutter and rock is established. It is shown that natural frequency on the cutter parts is higher, the frequency of first step is 4536Hz, and the most modes are deformations of the cutter loop, vibration acceleration of the cutter decreases with fracture tunnel width increasing, in some degree broken rock mechanics is achieved, foundation is provided for improving using life and adaptability of the cutter, and optimizing arrangement of plate cutter on the cutter head, and finally realizing high efficiency and low energy consumption.
