The analysis of belt conveyor models at different number of approximating masses

For the belt conveyor modeling, this study uses the method of systems composed of elements continuously distributed in finite spatial domains. The motion is transmitted from an element to an element, and the dynamic processes are described using equations with partial derivatives (wave equations). The analytical solution of the systems of such equations is a complex and labor-intensive process. It is possible to simplify calculations by splitting the system into the simplest elements and using the piece-wise linear approximation. This method allows an approximate description of the system with distributed parameters by a system of ordinary differential equations. In this case, the line of a belt conveyor is divided into a number of sections, and the law of variation of strain rate along the length is assumed to be linear within the limits of each section. Then, after certain assumptions for simplifying the model, the Lagrangian equations of the second kind are used. The authors compare the belt conveyor models with different numbers of concentrated masses and assess advantages of each models. The engineering problems solvable using these models are listed.
