- W4310387621 abstract "In this paper, the influence of kinematic parameters on cutting performance of oscillation disc cutter (ODC) is investigated by discrete element method (DEM). The ODC cutting model is established by DEM and validated by experiments. The results of simulation show that mean cutting force, mean torque and specific energy (SE) increase with eccentric ratio (RE) and velocity ratio (RV). Besides, the contact period between ODC and rock gets longer with RV increasing, resulting in more energy stored in the rock as strain energy rather than for rock breaking. The simulation results suggest that the cutting force is maximum at the crack initiation stage and decreases during crack propagation. Meanwhile, the fracture mode translates from ductile to brittle company with fewer tiny chips with the increase of cutting depth." @default.
