Simulation study the movement of materials in loader shovel working process based on EDEM

摘要

By application of the theory and methods of discrete element, a loader loading process three-dimensional simulation model was established, the simulation model established in EDEM software realized the visualization of loader inserting process. By three different particle size materials inserting process simulation, material motion characteristic could be obtained and the laws of motion of different size material were compared. Simulation results show that regardless of the particle size, compaction zone (dense core) were generated. For small particles, during insertion of the material there was a distinct shear slip plane and for coarse particles, slip plane was not obvious. The simulation results were consistent with the results of previous analysis and verified that the discrete element method and the model in the loading process were effective in the study.
