摘要:为研究螺旋滚筒结构对薄煤层采煤机截割性能的影响，基于MATLAB和VB编制采煤机载荷计算软件，对截割过程中螺旋滚筒载荷、截割阻力矩以及截割功率进行分析，得到A、B两种型号螺旋滚筒的截割阻力矩及截割功率分布规律。通过对具有柔性摇臂壳体、行星架和行星轴的采煤机刚柔耦合模型进行仿真，得到相应结构件的应力水平。研究结果表明：A型螺旋滚筒的截割阻力矩和功率消耗均大于B型螺旋滚筒；采用B型螺旋滚筒与MG400/951-WD型采煤机进行配套后，采煤机关键零件的受力状态能够得到明显改善。对定型后的采煤机在生产过程中进行跟踪，并对所用分析方法的准确性进行验证。研究结果可为螺旋滚筒截割性能的综合评价以及采煤机运动参数的合理匹配提供一定参考。

Abstract:In order to study the influence of spiral drum’s structure on the cutting performance of thin coal seam shearer， a calculation software of shearer load was compiled based on MATLAB and VB ， and the load of spiral drum， cutting resistance moment and cutting power in the cutting process were analyzed. The distributions of cutting resistance moment and cutting power of A and B type spiral drums were obtained. Through the simulations of shearer rigid-flexible coupling model with flexible rocker shell， planetary frame and planetary axis， the stress level of corresponding structural parts was obtained. It was found that the cutting resistance moment and power consumption of type A spiral drum were greater than those of type B spiral drum. The stress state of key parts of MG400/951-WD shearer with type B spiral drum could be significantly improved. The analytical method was verified by the production test of shearer. The research results could provide a reference for the compre-hensive evaluation of the cutting performance of the spiral drum and the selection of motion parameters.
