摘　　要：以∅4.5 m采煤机超大型截割滚筒为研究对象,在对其结构进行分析后,得出滚筒轮毂由于面积大、厚度小的结构特点而在大采高工作面的截割过程中稳定性较差。文章采用UG建模软件搭建截割滚筒的三维模型,并通过Ansys有限元仿真软件分析其强度及刚度,根据分析结果优化应力集中部位(加强筋)的结构,进而改善应力条件、提升设备性能。将优化后的采煤机截割滚筒部署到山西某矿大采高工作面的截割工作中,并连续监测8个月,结果表明:滚筒结构设计合理,试验期间稳定性良好,不仅加快了企业的生产进度,而且企业经济效益也得到了提升。In this article,the ultra large cutting drum of∅4.5m coal mining machine is taken as the research object;after the structural analysis,it is found that the drum hub has poor stability in the cutting process of high mining height working face due to its large area and small thickness.The 3D model of cutting drum is built by using UG modeling software,and its strength and stiffness is analyzed by using the Ansys finite element simulation software.Based on the analysis results,structure of the stress concentration area(reinforcing ribs)is optimized to improve stress conditions and enhance the equipment performance.The optimized cutting drum of the coal mining machine is deployed to the cutting work of a large mining height working face in Shanxi,and then continuously monitored for 8 months.The results show that the structural design of drum is reasonable,and the stability is good during the test period,which would increase the production progress and economic benefits of enterprises.
