Optimization Design of Circular Chain for Coal Mine Scraper Conveyor
Based on an overview of the main structure and working principle of the SGZ880/800 scraper conveyor,a finite element model of the circular link chain was established using UG and Workbench software.Through analysis,it was found that the stress distribution during the operation of the circular chain exhibits significant non-uniformity.Based on the topology optimization results,the outer 4mm volume of the linear segment of the circular chain can be removed.Taking the maximum stress of the circular chain as the optimization objective and two key structural dimensions as the optimization objects,response surface optimization was carried out.The maximum stress was reduced to 375.68MPa,which is 6.09％lower than the original structure,and the mass was also reduced by 10.52％.Applying the new circular chain structure to coal mine practice,technicians believe that the service life can be increased by more than 20％after 8 months of on-site application.
