Yuam oscillations

Electromagnetic oscillations qhib, nws muaj peev xwm yuav hais tau kom ib co raws li los ntawm lub caij nyoog. Dawb thiab yuam deeg tau pom lawv ntau daim ntawv thov nyob rau hauv peb lub neej txhua hnub. Electromagnetic oscillations yog siv nyob rau hauv ib tug ntau yam ntawm kev pab kiag li lawm, xws li nyob rau hauv lub loj xov xwm. Kuj tsis paub meej kev currents - nws tseem yog ib qhov hluav taws xob oscillations. Txawm lub teeb phenomena - yog electromagnetic vuag. Wb tham txog lawv nyob rau hauv ntau yam.

Hais txog cov txheej txheem nyob rau hauv deeg los yog lub zog, tshwm sim los ntawm ib tug ib ntus tsiag ntawv repeatability. Tej kev yog ntau. Lub cev xwm ntawm oscillatory dab yuav varied. Tswv yim los ntawm no, yog distinguished electromagnetic, mechanical, thiab lwm yam variations.

Ntawm cov ntau yam hluav taws xob phenomena dawb thiab yuam oscillations ntawm solenoid nyob ib tug tshwj xeeb qhov chaw. Nyob rau hauv electromagnetic oscillations to taub oscillations ntawm magnetic thiab hluav taws xob teb nrog ib tug periodic hloov nyob rau hauv voltage, tam sim no thiab xwb. Nyob rau hauv thiaj li yuav pib thiab ntxiv electromagnetic oscillations siv ib tug oscillating Circuit Court.

Yuam oscillations - cov oscillatory dab, uas yog tshwm sim los ntawm tus ntawm lwm rog rau lub system.

Yuam oscillations muaj nws tus kheej feature - lawv tsis fading cim. Lawv zaus sib npaug zos rau lub zaus ntawm lub periodic lwm cov quab yuam kom no oscillatory system. Txawm li cas los, nws yog tsim nyog los paub qhov txawv ntawm tej oscillatory tsab ntawv tsa suab ntawm nws tus kheej-oscillation. Thaum nws tus kheej-oscillation nyob rau hauv lub system yuav tsum mechanism "muab" nyob rau hauv lub system ntawm tej zog reservoir, nyob rau hauv lub sij hawm nrog lawv deeg, me me feem ntawm lub zog, muaj lawv tus kheej pab oscillations. Yog li, thaum nws tus kheej-oscillations system "pushes" nws tus kheej. Thaum yuam deeg ntawm ib tug system yuav siv sij hawm ib tug laub los ntawm sab nraum rog.

Tus zaus ntawm oscillation sib npaug zos rau lub zaus ntawm lwm quab yuam. Lawv amplitude yog muab tsis yog arbitrary, raws li nyob rau hauv free kev co, thiab yog teem rau nws tus kheej. Tus nqi ntawm cov amplitude nyob ntawm tus piv ntawm cov zaus ntawm cov sab nraud quab yuam, thiab lawv tus kheej.

Yuam oscillations characterizes lub phenomenon ntawm qhov hluav taws xob resonance. Thaum nws hauv amplitude oscillating ntawv tsa suab yog maximized. Lub oscillation amplitude ntawm resonance yuav infinitely loj. Nyob rau hauv qhov tseeb, thaum nws amplitude ntawm yuam oscillations ntawm electromagnetic finite. Nrog ib tug me me kuj nyob rau hauv lub system impedance ntawm resonance yog ib qho tseem ceeb. Qhov no ua rau cov amplitude ntawm vibrational tsab ntawv tsa suab nyob rau hauv lub kawg resonance. Thaum ib tug ntau dua kuj nyob rau hauv lub system ib tug tshaj plaws amplitude ntawm lub resonance point yuav tsawg dua.

Alternating tam sim no - yog tsis muaj lwm yam tshaj li qhov yuam electromagnetic oscillations tshwm sim thaum lub sij hawm kev sib hloov ntawm cov hlau nplaum nyob rau hauv lub thav duab los yog nyob rau hauv lub magnetic teb kev sib hloov ncej raws li ib tug tshwm sim ntawm electromagnetic induction. Lub alternator yog ib qho AC qhov chaw.

Electric teeb, nqus tsev vacuum, tub yees, TV, thiab lwm yam siv nyob rau hauv peb lub tsev, chaw ua hauj lwm nyob rau hauv lub hauv paus ntawm lub zog ntawm electromagnetic vuag. Lawv daim ntawv thov raws li kev ua hauj lwm motors, uas khiav lag luam cov cav tov, thiab lwm yam

Nyob rau hauv cov kev piv txwv, ib tug alternating tam sim no yog siv, nyob rau hauv uas hluav taws xob hwj chim circuits tshwm raws li ib tug tshwm sim ntawm excitation ntawm yuam oscillations.

Peb qhia hais tias cov dawb thiab yuam oscillations txawv los ntawm txhua lwm yam li ntawd ib txhia yog ua tsis lwm influences vim lub zog uas yog cia nyob rau hauv lub Circuit Court, thiab lwm yam tshwm sim los ntawm cov sab nraud cawv rau cov system.
