Dynamic Performance Analysis of Chain Drive System of Scraper Conveyor
In order to further explore the operating characteristics of the chain drive system of the scraper conveyor,this paper takes the SGZ1000/1050 permanent magnet direct drive scraper conveyor as the research object,and carries out simulation analysis on the dynamic performance of its chain drive system.By analyzing the changes of its contact force,speed,displacement and other indicators,it is determined that there are two risks of stuck chain and broken chain.It is also determined that the output speed control effect of permanent magnet direct drive system is the key index to determine the risk occurrence probability.In this regard,taking the stability of the output speed as the core objective,the control strategy is optimized by combining sliding mode control and fuzzy control.The results show that the output speed of the optimized system has higher stability,which is expected to improve the dynamic performance of the chain drive system of the scraper conveyor.
