Abstract
Usually the calculation of skirt board resistance is not taken seriously, but for the skirtplates with a great length, the calculation of skirt board resistance even may determine the driving power of the belt conveyor. This paper, based on the analysis of the basic principle of the skirt board resistance, divides the cross-section of the material into two parts, rectangle and trapezoid, and introduces Rankine theory to derive the calculation formula of skirt board resistance. It is concluded that the calculating results have great errors due to ignoring trapezoidal cross-section in the bottom part by u-sing the Chinese current (standard) calculating method. According to DIN22101, the computational procedure of skirt board resistance is givea Analysis of the examples and DEM simulation verify the correctness of the calculation method.关键词
