摘要
为了研究球形颗粒的堆积行为,开发了一个三维仿真系统ParticleSim。该系统建立在离散元法的基础上,包括预处理和运算求解。利用该系统研究了五组颗粒堆积的能量转换过程。
the packing movement behavior of a set of spherical particles is investigated.Three-dimensional system called ParticleSim is modeled to preprocess,simulate the mechanical behavior of a collection of particles in the specific system,in order to obtain a deep insight into the complicated packing process,especially the energy which could not be investigated by physics experiment method.DEM is used in the mechanics model.As a use of the system,the energy conversion of five cases are investigated.
