Abstract:

In order to analyse the rock breakage process of double-edge ball tooth hob cutter and get the related curve of intrusive force and invasion depth, the numerical simulation model of double-edge ball tooth hob cutter is accurately established. In the process of interaction between hob cutter and rock mass, the material model is also established, the mechanism of rock fragmentation is carefully researched, the elastic-plastic deformation is seriously studied. Finally, we design an experiment which has a good consistency with the simulation analysis.
