Dynamic Analysis of Cutter Head System in Tunnel Boring Machine
To obtain the reasonable layout and structure shapes of the various kinds of cutters in tunnel boring machine (TBM), the kinematic/dynamic of cutter head system was analyzed by using virtual prototype and finite element method (FEM). The velocity and force curves were got from different positions of cutters and the mode vibration of scrapers and cutter hobs were obtained to analyze their structural performances next stage. It is shown that these results can provide references for dynamic optimization design of tunnel boring machine. Therefore, it is necessary to implement kinematic/dynamic analysis and mode analysis before manufacture of production.
