Abstract:
Thescraperconveyorisavitalcomponentofmaterialtransportationinvariousindustries.Theshiftingbeam,beinganessentialpartofthescraperconveyor,playsasignificantroleinmaintainingthestructuralintegrityandstabilityoftheconveyorsystem.Thispaperaimstoanalyzetheforcedistributionontheshiftingbeamandproposeanoptimizeddesignforimprovedperformance.
1.Introduction
Thescraperconveyoriswidelyusedinindustriessuchasmining,construction,andagricultureforthetransportationofbulkmaterials.Theshiftingbeamisresponsiblefortransferringtheverticalandhorizontalforcesfromthescraperbladestotheconveyorbody.Therefore,analyzingtheforcesactingontheshiftingbeamiscrucialforunderstandingitsstructuralbehaviorandoptimizingitsdesign.
2.ForceAnalysis
2.1.VerticalForces
Theverticalforcesactingontheshiftingbeamprimarilycomefromtheweightoftheconveyedmaterialandthescraperblades.Theanalysisconsiderstheweightdistributionofthematerialalongtheconveyorlengthanddeterminesthecorrespondingverticalforcedistributionontheshiftingbeam.
2.2.HorizontalForces
Thehorizontalforcesarisefromtheresistanceforcesduringmaterialtransportation.Theseforcesaretransferredtotheshiftingbeamthroughthescraperblades.Bystudyingthefrictionbetweenthematerialandtheconveyorbottom,aswellastheinteractionbetweenthebladesandthematerial,thehorizontalforcedistributionontheshiftingbeamcanbedetermined.
3.StressAnalysis
Basedontheforcedistributionontheshiftingbeam,stressanalysistechniquessuchasfiniteelementanalysis(FEA)canbeutilizedtodeterminethestressdistribution.Byevaluatingthestresslevelsatdifferentlocations,potentialareasofconcern,suchasstressconcentrationsandweakpoints,canbeidentified.
