OPTIMIZATION OF SCRAPPER CONVEYOR RUN MODES CONTROL BASED ON THE ANALYSIS OF IMITATION MODELLING
The article discusses the basic principles of controlling the dynamic characteristics of the scraper conveyor, modeling of various modes of starting the conveyor. The purpose of this research work is to conduct a comparative analysis of modern start - up modes of the scraper conveyor, to determine the safest and most reliable way to control key parameters of the conveyor installation. Based on the technical characteristics of the scraper conveyor type SGZ-800/630 and the parameters of the conveyor in the excavation areas, various modes of the scraper conveyor start - up were simulated in the dynamic simulation environment of complex Simulink systems (MATLAB). As a result of the research, an analysis of the control of the dynamic characteristics of the input signal is shown, a simulation of the initial characteristics of the start - up of the scraper conveyor is carried out, which made it possible to single out the characteristics that have a greater influence on the process of starting the system as a whole. Upon completion of the work, it was revealed that the control of the scraper conveyor using a two - stage start - up is the most effective way, it can significantly reduce the level of fluctuations in the chain tension and increase the reliability of the installation at critical load moments.
