Optimised Design and Practical Research on the Structure of Central Trough of Mining Scraper Conveyor
Using UG and ANSYS Workbench software to establish the finite element model of the middle trough structure of scraper conveyor,the fatigue life of the middle trough was analysed,and it was found that the fatigue life of the root area of the fascia plate was 7,002 years,which was the root cause of the easy occurrence of stress concentration at this location.The fatigue life is optimised in Workbench using the rounded corner of the reinforcement plate and the thickness of the reinforcement plate as the optimisation objects and the fatigue life as the optimisation target.After optimisation,the minimum fatigue life of the central slot is increased to 8 239,which is 17.67％.The optimised structure is applied to SGB420/40 scraper conveyor,and the practical test is carried out for 6 months,and it is found that the overall operation of the structure is stable and achieves the expected effect,which creates a very good safety benefit and economic benefit for the enterprise.
