Mathematical model of operation of stacker belt conveyors of mobile road-building machines with tracing control of belt tension

Abstract

The paper proposes a mathematical model of operation of stacker belt conveyors of mobile road-building machines with tracing control of belt tension. This model allows one to evaluate the operation processes of the conveyor taking into account the variation of the rolling resistance coefficient of the belt on the dumping track, as well as to determine parameters of the tracing tensioning devices with a view to further selecting the appropriate driven equipment. On the example of a stacker conveyor of a mobile power washer, construction features of the proposed mathematical model are shown. Some regularities of the operation of short conveyors, which make it possible to increase efficiency of the designing process, are identified.
