摘要

为从源头数据保证离散单元法(DEM)模拟的精确性,有必要对模拟用的炉料系数进行试验测量。试验测定了DEM模拟用高炉炉料间的静摩擦因数和恢复系数,然后通过验证休止角的方式确定了动摩擦因数,从而建立了高炉DEM模拟所用炉料的相关参数,为高炉DEM精确模拟提供了数据库,奠定了良好的基础。

Abstract

It is necessary to experimentally measure the coefficients used in the discrete element method (DEM) simulation in order to guarantee the accuracy of the simulation from the source. Therefore, static friction coefficients and restitution coefficients between different burden materials used in the DEM simulation are measured by experiments. The rolling friction coefficients between burden materials are determined by validating the repose angle of the burden. Parameters of burden materials used in the DEM simulation are determined, which provides a database for the accurate DEM simulation.
