Study on dynamic characteristics of scraper conveyor under various scraper configurations

Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering
This study aims to explore the impact of scraper structure on the stable operation of scraper conveyors. A simulation test is designed to investigate the effect of the scraper's lower inclination angle on the wedge-shaped structure of the scraper. Based on the test results, modifications are made to the scraper's lower inclination angle.

Evolutionary Approach for Tuning of Longwall Scraper Conveyor Model

2017
The modeling of machines and their operation modes is a key approach for optimization of their performance as well as for avoiding unwanted operational states which may lead to the occurrence of faults, and finally, to the breakdown. The developed model of a machine should be always parametrized, i.e. the certain number of parameters should be selected
