摘　　要：在分析比较几种研究方法的基础上,用相似模拟方法确定影响采煤机螺旋滚筒装煤这一复杂现象的基本物理量,采用量纲分析法导出相似准则,确定模型各参数的相似比例缩尺,用它来指导模型试验,使试验结果便于推广到原型。Based on the analysis of several research methods, use a method of analogy to acquire parameters which affect the loading efficiency of the screw loading machine in horizontal coal bin. The analogy criterions and equations are built thought dimension analysis and the proportion of parameters is also acquired. By this means, the result of model trial can be used to archetype.
