Topology Optimisation Study on Circular Chain of Scraper Conveyor based on Finite Element Method
The circular chain of scraper conveyor is studied based on finite element method and topology optimisation method.Firstly,the finite element model of the circular chain is established based on ANSYS Workbench software,and it is found that the maximum stress and strain are mainly concentrated in the inner part of the circular arc,and the stress and strain in the outer part of the straight cylinder are smaller.Taking the overall mass of the chain as the optimisation objective,and considering the processing cost of the chain,the optimised solution is to remove 4 mm thickness from the outer part of the straight cylinder,which reduces the mass of the chain by 3.8％.The optimised circular chain structure was applied to the scraper conveyor and was tested in practice for a period of 6 months,achieving the expected results.
