Qhov sib txawv tseem ceeb ntawm damped oscillation thiab yuam oscillation yog tias damped oscillation yog qhov txo qis hauv amplitude ntawm oscillator, whereas yuam oscillation yog oscillation uas tshwm sim thaum lub oscillating system yog tsav los ntawm lub sij hawm quab yuam uas yog sab nraud rau lub oscillation. oscillating system.
Oscillation yog lub zog rov qab thiab tawm mus hauv lub suab tsis tu ncua. Muaj ob hom oscillation loj li damped oscillation thiab yuam oscillation. Damped oscillation yog hais txog oscillation uas degrades nyob rau lub sijhawm tshwj xeeb. Kev quab yuam oscillation, ntawm qhov tod tes, hais txog oscillation uas tshwm sim vim qhov cuam tshuam ntawm lub zog sab nraud.
Damped Oscillation yog dab tsi?
Damped oscillation yog hom oscillation uas tshwm sim los ntawm kev txo qis ntawm qhov amplitude ntawm oscillator. Nyob rau hauv ib qho system uas muaj hom oscillation, lub amplitude ntawm oscillation maj mam txo nrog lub sij hawm. Qhov tseeb, lo lus damping hais txog qhov no txo qis ntawm amplitude. Peb tuaj yeem txhais damped oscillation yooj yim raws li oscillation uas degrades dhau lub sijhawm tshwj xeeb ntawm lub sijhawm. Qee qhov piv txwv ntawm hom oscillation no suav nrog qhov hnyav ntawm lub caij nplooj ntoos hlav, lub viav vias pendulum, thiab RLC circuit.
Daim duab 01: Damped Oscillation
Ntxiv mus, thaum raug lub damped oscillator rau lub damping quab yuam, (yuav tsum yog linearly nyob ntawm qhov nrawm zoo ib yam li cov viscous damping), lub oscillation nyhav muaj cov ntsiab lus exponential decay uas zoo li nyob ntawm tus damping coefficient.. Peb tuaj yeem nthuav qhia lub zog damping raws li hauv qab no:
Qhov twg F yog lub zog damping, c yog qhov sib txawv ntawm qhov sib txawv, thiab v yog qhov nrawm. Yog li ntawd, peb tuaj yeem nthuav qhia cov coefficient damping raws li hauv qab no:
Ntawm no, m yog qhov loj ntawm oscillator. Qhov no txhais tau hais tias lub zog damping yog proportional rau c tab sis inversely proportional rau qhov loj ntawm oscillator.
Dab tsi yog yuam kev oscillation?
Forced oscillation tuaj yeem piav qhia tias yog hom oscillation uas tshwm sim thaum lub oscillating system yog tsav los ntawm lub sij hawm quab yuam uas tshwm sim sab nraud rau oscillating system. Nyob rau hauv sib piv, dawb oscillations tshwm sim thaum lub cev oscillates nrog nws tus kheej zaus. Lub cev uas raug yuam kom oscillation zoo li oscillate nrog zaus ntawm lub sij hawm quab yuam.
Ib qho piv txwv yog thaum tus me nyuam siv nws txhais taw txav lub viav vias lossis thaum lwm tus neeg thawb lub viav vias kom tswj tau qhov txav. Ntxiv mus, resonance tuaj yeem muab tau raws li qhov tshwj xeeb ntawm kev yuam kom oscillation.
Qhov txawv ntawm Damped Oscillation thiab Forced Oscillation yog dab tsi?
Damped oscillation thiab yuam oscillation yog ob hom oscillations. Qhov sib txawv tseem ceeb ntawm damped oscillation thiab yuam oscillation yog damped oscillation yog qhov txo qis hauv amplitude ntawm oscillator, whereas yuam oscillation yog oscillation uas tshwm sim thaum lub oscillating system yog tsav los ntawm lub sij hawm lub zog uas yog sab nraud rau oscillating system.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm damped oscillation thiab yuam oscillation hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Damped Oscillation vs Forced Oscillation
Damped oscillation yog hais txog oscillation uas degrades nyob rau ib lub sij hawm ntawm lub sij hawm thaum yuam oscillation yog hais txog oscillation uas tshwm sim vim qhov tshwm sim ntawm lwm lub sij hawm quab yuam. Qhov sib txawv tseem ceeb ntawm damped oscillation thiab yuam oscillation yog damped oscillation yog qhov txo qis hauv amplitude ntawm oscillator, whereas yuam oscillation yog oscillation uas tshwm sim thaum lub oscillating system yog tsav los ntawm lub sij hawm lub zog uas yog sab nraud rau oscillating system.
