Modeling of various modes of belt conveyor braking

The purpose of the work is to consider the braking modes of the conveyor belt. When the conveyor is stopped or decelerated, compression and stretching waves occur in the belt, the propagation of which leads to slipping of the belt. This entails the wear of the tape and the breakdown of other equipment, which requires expensive repairs. The article presents the results of modelling conveyor braking in the programs SimPowerToolbox and Simulink. The results obtained allow us to compare the free run-out of the conveyor and the forced braking. The main results of the work are the obtained transient processes of the stator and rotor currents, the speed of rotation of the motor during braking of the conveyor, the speed of movement of the conveyor belt, the forces in the belt and the traction factor, the efficiency of the engine. Conclusions: the developed model allows us to investigate the dynamic operating modes of the engine and the mechanical part of the conveyor, to analyze the forces arising in the belt during braking, to evaluate the slip of the belt and the magnitude of the traction coefficient In both cases, the graphs clearly show an increase in the speed of the tail drum caused by a compression wave passing through the freight branch, then we can recommend preliminary braking of the tail drum so that the Euler condition is met. The amount of braking force can be calculated in advance using a proportional relationship between the forces of resistance to the movement of the belt that occur during braking of the tail drum and the amount of friction force between the brake pad (or disc) and the drum. In addition, the results obtained can be used in the development of a belt speed control system depending on the volume of random freight traffic entering the conveyor.

Keywords: starting and braking modes of the conveyor belt, braking torque, forced braking, free run-out, controlled tensioner, traction factor, dynamic forces in the belt, mathematical modelling.
