摘要

摘要: 为了提高采煤机螺旋滚筒的截割性能，利用量纲分析法得到了滚筒截割系统的相似准则方程及各参数的相似比；以某型采煤机螺旋滚筒为原型，基于相似理论设计了一种新型大采高采煤机滚筒，并用采煤机滚筒辅助设计软件进行了相似性验证，再将其与缩尺模型进行对比分析。结果表明：相似模型与原型保持着良好的截割性能相似性，其切削面积比原型增加了17%，且基于相似理论的设计方法优于缩尺转换方法，为采煤机螺旋滚筒的快速设计提供了一种新途径。

Abstract: In order to improve the cutting performance of shearer drum, the similarity criterion equation of drum cutting system and the similar ratio of parameters were obtained based on dimensional analysis; Aimed at the prototype of the spiral drum of a shearer, a new type of large mining high shearer drum was designed based on similarity theory. The similarity was validated by the shearer drum aided design software, and the comparative analysis was performed with a scaled model. The results show that the similarity model and the prototype maintain a good similarity in cutting performance, the cutting area is increased by 17% compared to the prototype, and the design method based on similarity theory is better than conversion method based on scale theory, which providing a new approach for the rapid design of the spiral drum of shearer.
