摘要
离散元素法仿真离散系统需要解决的关键问题有:确定离散系统颗粒的颗粒形状模型,根据颗粒的位置判断是否接触并根据接触模型计算颗粒的接触力。本文主要探讨离散元素法在球磨机研究中的应用,采用离散元素法实现对整个离散系统的任意时刻的运动、受力、能量的求解。
The need to address the key issues of the discrete element method simulation of discrete systems ： to identify discrete system model of particle shape of the particles, the particleg position to determine whether exposure to particle contact force and contact mod- el. In this paper, the application of discrete element method in a ball mill study the movement of the entire discrete system at any time, using the discrete element method, force, energy solving.
