Abstract

Thethermoelasticcouplingstabilityoftheaxiallymovingbeamundertheactionofuniformlydistributedtangentialfollowerforceswasinvestig ted.Thedifferentialequationofmotionforthe axiallymovingbeamundertheactionofuniformlydistributedtangentialfollowerforceswasestablished, andtheeigenequationfortheaxiallymovingbeamwithtwokindsofboundaryconditionssubjectedtofollowerforceswasderivedbyanormalizedpowe seriesmethod.Thefirstthreeordersdimensionlesscomplexfrequenciesofthesystem werecalculated,andtheeffectsofthedimensionless movingspeed,thedimensionlessthermoelasticcouplingfactor,thedimensionlessfollowerforceson thestabilityoftheaxiallymovingbeaminthethermoelasticcouplingcasewereanalyzed.
