Errors and ways of their elimination in the calculation of belt conveyors
Abstract
One of the currently widely used methods of calculation of belt conveyors consists in a preliminary calculation, the initial position of which is the approximately determined value of power on the drive shaft of the conveyor, and in the final calculation - the method of determining the tension in characteristic points of the contour of the traction body. In this method, the accuracy of the final calculation depends on the accuracy with which the preliminary calculation determines the weight of a linear meter of belt. The practice of calculations shows that in a number of cases the error in preliminary determination of belt weight can reach a significant value, as a result of which the final calculation turns out to be insufficiently accurate.The main errors in the preliminary calculation are as follows: 1) the maximum tension of the belt is determined by a formula that is not valid for all cases encountered in practice; 2) the weight of moving parts of the conveyor is taken tentatively.
