The Simulation of Cutter-Rock Interaction in PFC

Abstract:

TBM is a modern machine used in the underground engineering. This machine excavates tunnel with the cutters arranged on its cutter head. The research of the cutter-rock interaction is an important work in improving the machine's behaviour. A simulation of the interaction is presented in this paper. The effects of the rake angle, blade angle and cutting depth on cutter force and crack number in rock are discussed, which provide a complement to the cutter-rock interaction research.
