Mathematical Representation of a Conveyor Belt as a Dynamic Load of an Electric Drive.

An isomorphous dual line diagram of the model structure is presented which is a continuation of the abstract model of the drive of a belt conveyor for long distance transport introduced by the author in a previous paper. The dynamic characteristics of the elements of the diagram and their parametric changes are determined. Nonlinear, nonhomogenous parametrical integrodifferential equations are deduced of a belt conveyor conceived as the technological part of an electromechanical drive system of the conveyor. Time is the independent variable and simple space-time dependences are introduced. The mathematical solution of the system equations is indicated. The results can be used for the design of electrical drives of belt conveyors for long distance transport.
