The Analysis of the Parameters of Rock Cutting by Disc Cutter Based on ANSYS
When TBM tunneling, the disc cutter directly in contact with the rock. The disc cutter is an important component of the TBM, so the numerical simulation study of disc cutter breaking rock process is established. The study contents disc cutter exerted vertical force on the rock. This is instructive for improving the disc cutter layout and improving the rock breaking capacity and tunneling efficiency. According to the rock Drucker-Prager plastic yield criterion lines and rock mechanical properties, finite element model of rock breaking by disc cutter was established by ANSYSWORKBENCH software and process of rock cutting with disc cutter was simulated. The rock elastic-plastic deformation occurred in the disc cutter effect, caused accumulation of rock damage, when the rock breaks completely damaged, get the vertical force exerted on the disc cutter, which is significance for the disc cutter layout and the calculation of force of TBM cutter breaking rock.
