Numerical Modeling of the TBM Disc Cutter’s Kinematic Behavior during its Wear Process and Experimental Verification

Abstract:

In order to determine the disc cutter’s kinematic behavior, a 3-D FEM model is established to simulate the rock cutting process in Abaqus, using a unique connector element and considering the failure effect of the rock. Then, by using this model, a series of numerical simulations during disc cutter’s wearing process have been performed. The results show that the speed zero point is jumping near the deepest rock breaking point, the rotating speed of the disc cutter varies while it is cutting rock and the average rotating speed increases during its wear process. In the end, the laboratory test is presented in detail, and the experiment results are in accordance with the simulation results.
