Numerical simulation on the impacting and comminuting of coal based on LS-DYNA

  • Published:
Journal of Coal Science and Engineering (China)

Abstract

Simulated comminution that the coal impact rigid wall using finite element software of explicit formulation based on dynamics model of elastic collision (Hamilton variationnal principle), the critical velocity of the coal impacting comminution was about 10 m/s, and validated the release effect of pressure in the coal impacting comminution, and then extend applied field of the finite element software of explicit formulation LS-DYNA analysing impact comminution of the elastic-plastic material. The simulation result has great guidance and reference value for understanding the impact comminution mechanics of coal and other material and manufacturing comminution equipment.
