摘　　要：用岩石作为研究目标,以便携式关节臂测量机与Scanworks V5激光扫描测头配合工作的方式对岩石各表面进行扫描,利用Geomagic Studio软件对扫描获取的点云数据进行后处理得到精度较高、质量较好的三角形面网格形式的岩石几何边界模型。在EDEM中采用有重叠法对岩石几何边界内部区域进行颗粒填充,实现几何形状不规则的岩石颗粒的三维离散元建模。方便后续利用离散元软件EDEM对已建好三维离散元模型进行仿真分析,研究不同的颗粒尺寸、形状及颗粒分布等因素对材料的微观力学性能的具体影响。Articles with rocks as a research objective, the way to portable articulated arm measuring machine and Scanworks V5 laser scanning probe work on rock surface, and then use the Geomagic Studio software for post-processing by scanning point cloud data to obtain a high precision, good quality rock geometric boundary model of the triangular surface mesh form, The overlap method is adopted in the EDEM to grain filling of rock the inner regions of the geometric boundary, so as to realize the geometric shape of irregular rock particles of three dimensional discrete element modeling.Easy to follow using the discrete element software EDEM has been built on the model of discrete element simulation analysis, the research on different factors such as, particle size, shape and size distribution of the micro mechanical properties of materials in a specific effect.
