Embodiment Construction
[0028] The specific implementation of the present invention will be described in detail below in combination with the accompanying drawings and technical solutions, and the present invention will be further described.
[0029] Such as figure 1 Shown is a flow chart of a TBM cutterhead vibration limit analysis method. Including the following steps: a), data preprocessing; b), external excitation research of TBM cutterhead; c), determination of allowable stress of cutterhead under different working conditions; d), cutterhead transient dynamics analysis; e), Dynamic Response Analysis of Cutterhead
[0030] TBM cutterhead vibration limit analysis method, the three-dimensional force of the hob under different compressive strength rock conditions is obtained through the hob-cutter rock breaking simulation, and is corrected by the actual measurement data on the construction site, which is used as the external excitation of the model to perform transient Dynamic analysis, and then m...
