Abstract

The pick cutter, which directly contacts and crushes the rock, is the expendable part of a roadheader. The arrangement and angle of attachment of the pick cutter are important factors that determine excavator performance. It is necessary to numerically calculate the contact between the pick cutter and rock. The rock is defined as a set of particles using the discrete element method. The parallel bond model is used to define the bonds between particles. The properties of granite that are measured by the uniaxial compressive test are applied to the numerical rock model. The pick cutter is defined by the polygon elements. The linear cutting simulation is considered to simulate the contact between the pick cutter and rock. The results of the simulation show the rock breaking due to contact with the pick cutter.
