摘　　要：为研究复杂煤层赋存条件下薄煤层采煤机滚筒的载荷特性,根据煤层赋存条件与采煤机工作状态,提出了截齿工作状态的判定条件,并设计出了不同工况下滚筒载荷仿真方案。以某薄煤层采煤机滚筒为研究对象,仿真得到五种典型工况下滚筒的载荷谱;分析了采煤机截割阻力矩、截割功率随滚筒转速和牵引速度变化的规律。研究结果表明:截割硬质包裹体受到的载荷波动明显高于其他工况;滚筒转速越高,负载转矩相对于牵引速度的变化范围越小,截割功率沿滚筒转速和牵引速度增大方向不断上升。In order to analysis the load characteristics of thin seam shearer drum under complex geological conditions, the determination conditions of tooth working state were proposed, the drum load calculation scheme was designed according to the condition of coal seam and the working state of shearer. A thin seam shearer drum as the object of research, the load spectrums of drum under five typical working conditions were calculated, the law of cutting resistance moment and cutting power with different drum revolution speed and haulage speed was analyzed. The results show that: the load fluctuation from cutting hard inclusions is significantly higher than other four conditions. Variation range of load torque respect to the change of haulage speed diminishes with the increase of drum revolution speed, cutting power along the drum revolution speed and haulage speed increases rising in both directions.
