非均匀颗粒自然堆积过程的计算机仿真

Computer Simulation of Natural Accumulation Process of the Non-equigranular Particles

通过对非均匀颗粒的自然堆积过程进行计算机仿真，获得了散体的分形特性，为散体的物性研究提供了较详细的几何结构信息。拟议了自然堆积过程的计算机仿真实现方法，确定了随机堆积形成的散作的分形维数，仿真结果与己有数据相比较，表明了该方法的可行性。

By computer simulation technique the natural accumulating process of the non-equigranular particles is studied in this paper. The fractal characteristics of bulk material are obtained. So the detailed information for the geometrical structure can be used for further study on the physical properties of bulk material. A computer simulation method of the natural accumulating process is proposed, the fractal dimension of bulk material accu mulated is determined. Comparing the results with the data obtained by means of experimental measurements indicates that the proposed computer simulation method is feasible.
