随着研究深度的不断开拓,带式输送机研究逐步得到细化,并且取得了一系列的成果,研究成果的应用对保障矿山安全作业,保障生命财产安全具有重大意义。滚筒作为带式输送机的主要部件,引起了技术人员越来越多的关注。关注滚筒的设计质量,强化滚筒的性能,对推动带式输送机系统的整体安全性和可靠性提供了强有力的支撑。
基于大量的带式输送机滚筒应用的实际案例,在总结了带式输送机滚筒的应用机理和受力特点后,本文进一步做出了三点突破:其一,滚筒结构的优化设计:滚筒的结构及尺寸极大地影响着滚筒的整体质量。结合现场实际应用中的案例,本文提出了新型改向滚筒的设计结构,设计的主体思想是将轴承外置转变为轴承内置。结构的改变带来性能上的极大提高,在满足生产实际的前提下达到了理想的优化效果,对生产实际具有极大的指导意义;其二:寻求最佳参数组合,优化细部尺寸:通过确定未知参数,建立函数及约束条件,运用数学的思想,开发出 MATLAB 编译语言,合理的确定了细部结构参数,其中重要的突破在于确定了传动滚筒中辐板的位置,确定了筒皮厚度及辐板厚度值,达到了优化滚筒结构的目的,为后续带式输送机滚筒的参数细化研究提供了参考; 其三,编写设计程序,提高设计效率:本文围绕滚筒的设计计算,借助 MATLAB 软件开发了简单实用的参数设计程序,为一系列参数,尤其是细部参数的计算给出了参考, 这极大地提高了设计计算的效率。
最后文章借助 分析软件,对优化设计结果进行了有限元分析,
分析结果显示优化设计效果明显,达到了优化结构的目的,进一步验证了细部参数优化以及新型结构设计对生产实际的指导意义。

ABSTRACT
With the depth research of the belt conveyor, more and more achievements have been achieved. Those achievements make great difference in Mine safety operation, which enhance the life and property security. The drum causes great concern as a main part of the whole system. The technicists improved the design quality and perfomance of the drum, improving the realiability of the whole system.
Based on large quantities of the cases of practical application, the paper summarizes the general law and the characteristics of the drum in a whole belt conveyor system. The paper makes breakthrough at three points: First, making optimal design of a new-typed turnabout drum. The author changed the location of the bearing in a turnabout drum from bearing built-in to bearing built-out, which may upgrade the drum’s performance; Second, optimizing the detail parameters. The author gets the detail parameters of some important parts of the driving drum in a mathematical way. With the help of the assembly language, the paper gets the actual value of the radial plate thickness and the drum surface thickness, as also the location of the radial plate in a drum. Third, preparing program functions. The paper develops a program in MATLAB according to the d
