摘要

介绍离散元法的数值计算方程和螺旋滚筒理论装煤率的计算方法,并结合工程实际项目,根据采煤机滚筒叶片的螺旋升角、厚度、煤与叶片的摩擦因数、滚筒转速等相关参数计算出采煤机的理论装煤率。利用Pro/E软件建立了采煤机装煤系统模型并将其导入到通用CAE软件EDEM中,根据煤层赋存条件及采煤机实际工况对装煤系统仿真模型的材料和属性等参数进行设置。通过对滚筒装煤率离散元仿真的结果和理论装煤率进行研究和分析,验证了离散元法对采煤机滚筒装煤效果仿真研究的可行性和分析的准确性,为离散元法在采煤机装煤性能方面的研究提供了重要参考。

Abstract

Introduces the method of calculating equation and theory of spiral drum loading rate numerical discrete element method,and combined with the actual project,according to the shearer drum blade helix angle,thickness,coal and blade friction coefficient,roller speed and other related parameters to calculate the theoretical rate of coal mining machine. The establishment of the coal mining machine model and introduced into the general CAE software using EDEM Pro-e software,set according to the actual conditions of coal seam conditions and coal mining machine system simulation model and parameters such as material properties. The discrete element simulation of the loading rate of loading rate results and theoretical research and analysis,to verify the accuracy and feasibility analysis of the research on Simulation of shearer drum loading effect of discrete element method,provides an important reference for the research on Shearer loading performance of the discrete element method.
