Aeroelastic flutter, txhais tau tias " qhov tsis ruaj khov, nws tus kheej zoo siab cov qauv oscillation ntawm qhov tseeb uas lub zog raug rho tawm los ntawm cov dej ntws los ntawm kev txav ntawm cov qauv", yog ubiquitous nyob rau hauv ntau yam engineering fields.
Dab tsi ua rau aeroelastic flutter?
Buffeting yog qhov tsis txaus ntseeg siab, tshwm sim los ntawm huab cua sib cais lossis kev poob siab yoj oscillations ntawm ib yam khoom tawm tsam lwm tus. Nws yog tshwm sim los ntawm ib qho kev cia siab ntawm kev thauj khoom nce. Nws yog random yuam kev vibration. Feem ntau nws cuam tshuam rau tus Tsov tus tw ntawm lub dav hlau qauv vim huab cua ntws qis ntawm lub tis.
flutter Aerospace yog dab tsi?
Flutter tshwm sim thaum cov kev txwv tsis pub muaj kev sib cuam tshuam ntawm cov kua dej mus txog qee qhov tseem ceeb. … Cov xwm txheej uas paub zoo tshaj plaws ntawm flutter yog cuam tshuam nrog flutter nyob rau hauv dav hlau tis, tails, thiab tswj chaw. Flutter yog ib qho xwm txheej hauv davhlau uas tshwm sim dhau ntawm qee qhov kev sib tw ceev-qhov siab.
elevator flutter yog dab tsi?
Aileron tshiab los yog lub elevator uas hnyav dhau heev(vim siv cov khoom siv hnyav dua lossis tsis hu rau kev txhawb nqa) tuaj yeem ua tau yooj yim. Flutter yog qhov nyuaj tshaj plaws los txhawm rau hauv qhov loj lossis hnyav tswj qhov chaw thiab qhov sib npaug ntawm qhov hnyav yuav tsum dhau mus.
qauv aeroelastic yog dab tsi?
Ib tus qauv aeroelastic ntawm lub tis / cav system ntawm kev lag luam lojaircraft tau tsim. Muab rau hauv tus account lub cav inertia quab yuam thiab thrust, zoo li qub aeroelastic deformation ntawm lub tis qauv thiab load distributions nrog rau shear force, dabtsi yog khoov lub sij hawm thiab torque.
