摘　　要：针对悬臂式掘进机截齿磨损严重、过载停机以及截齿受力不均而被损坏等情况,通过建立截割头和煤岩的3D模型,分析截割头载荷的数学模型,对截割头截齿部分进行受力分析,针对截割头的截齿排列提出合理性方案,使各截齿受到外力差异减小,进而提升掘进机的性能并获取更大的生产价值。In view of the serious wear, overload stop and damage caused by the uneven force of cutting head and coal rock, the 3D models of cutting head and coal rock are established, and the load of cutting head is analyzed. A reasonable scheme is proposed to reduce the difference of external force on the cutting head, and then improve the performance of the roadheader and obtain greater production value.
