DISCRETE ELEMENT METHOD ANALYSIS SIMULATION METHOD FOR PARTICLE MODEL, DISCRETE ELEMENT METHOD ANALYSIS SIMULATION PROGRAM AND DISCRETE ELEMENT METHOD ANALYSIS SIMULATION DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a discrete element method analysis simulation method, a discrete element method analysis simulation program and a discrete element method analysis simulation device, wherein a polygonal particle model introduced with rolling resistance, i.e., rotary motion of polygonal particles is introduced. PSOLUTION: This discrete element method analysis simulation method for analyzing behavior of a large number of analysis target particles includes: a step of imparting a physical property value to a virtual particle; a virtual particle arrangement step of arranging the virtual particles; and a behavior simulation step of simulating the behavior of the analysis target particles. The behavior simulation step includes a step of measuring a particle attitude angle between the analysis target particles and/or the virtual particles. In the behavior simulation step, about the analysis target particles and/or the virtual particles, the behavior of each particle is obtained by solving a motion equation formulated based on the rotary motion.
