采煤机螺旋滚筒随机载荷的模拟

Simulation of Random Loads on a Shearer's Helical Drum

文章建立了截齿受力和滚筒载荷的数学模型。在此基础上，利用计算机模拟的方法，得到了螺旋滚筒的随机载荷，并对其结果进行了统计分析，所得结论对于采煤机动态特性与动力学行为的研究具有重要意义。

Mathematical models of forces on a pick and loads on a drum are set up in the paper. On the basis, random loads on a helical drum are presented by means of comput- er's simulation, and the statistic analysis of them are performed. The conclusions mean a great deal for researching dynamic performance and dynamics action.
