Simulation of Disc Cutter Loads Based on ANSYS/LS-DYNA

Abstract:

In order to solve serious damage of pick on part-face tunnel machine during hard rock cutting, explore the applicability of disc cutter on the machine, the structure of disc cutter was designed, a model of dist cutter was built with Pro/E software, finite element model was established in ANSYS/LS-DYNA, the vertical force and rolling force of a disc cutter were obtained by simulation of cutter cutting. Analysis shows that the disc cutter can cut granite whose hardness is 106.2MPa, so the disc cutter can cut hard rock. The vertical force and rolling force agreed with common prediction formula of disc cutter forces which showed that modeling method is correct and feasible, this paper lays the foundation for the design and development of a cutting head of hard rock roadheader.
