摘　　要：重型板式给料机是矿山、冶金、港口、化工行业的重要设备,但在专业手册中,入料口的剪切阻力以及物料与裙板之间的摩擦阻力计算方面没有统一、系统的理论,有些甚至自相矛盾。本文从建立微分方程开始推导出一系列的阻力计算解析解,该理论对大型重型板式给料机设计具有重要的意义。The heavy-type plate feeder is the important equipment in the mine, metallurgy, port, and chemical indus- tries. In the professional service manuals, there is no unified and systematic theory regarding calculation of shear resistance at feeding inlet and frictional resistance between the materials and skirt board, or even self-contradictory. The paper intro- duces an analytical solution of resistance calculation induced by the differential equation, which provides significance for design of large heavy-type plate feeders.
