Stress resonance. Maxaa resonance circuit

Resonance waa mid ka mid ah kuwa ugu badan ee dabiiciga ah, ifafaale jirka. Arrin ku resonance oo laga dheehan karo in hababka farsamoyaqaanka, korontada iyo xataa kaamerada. Aan resonance, ma aanan haysan raadiyaha, telefishanka, music iyo xataa daabka ee garoonka, in aan ku xuso nidaamka wax ku ool ah ogaanshaha loo isticmaalo daawada casriga ah. Mid ka mid ah noocyada ugu xiiso leh iyo faa'iido leh Bannaanka resonance waa danab resonance ah.

Canaasiirta Bannaanka resonant

Resonance yaabaa inay ku dhacaan in loogu yeero RLC-wareeggeedii, oo ka kooban qaybaha soo socda:

• R - resistors. qalabka la xiriira xubno firfircoon Bannaanka korontada ee loo yaqaan, tamarta korontada waxaa beddelay kulaylka. In si kale loo dhigo, waxay ka circuit saaro xoog iyo waxa loogu badalo galay kulaylka.
• L - inductance. Inductance in wareeggeedii korontada - analog of mass ama tiiro in nidaamka farsamo. qayb Tani ma aha mid aad dareemi soo wareegi jiray ilaa aad isku daydo inaad u samayn in isbedel kasta. In farsamo, tusaale ahaan, isbeddelka noocan oo kale ah waa isbedelka ku dhacay xawaare. Bannaanka korontada - isbedel hadda. Haddii ay sabab qaar ka mid ah waxay ku dhacdaa, inductance ku counteracts isbeddel nidaam circuit sida.
• C - Magacani capacitors, kuwaas oo ah qalabka ku kaydiso tamarta korontada, sida guga hayn tamarta si farsamaysan. xoogga Inductance iyo dukaamada tamarta magnetic, halka mas'uul capacitor ee xoogga iyo sidaas kaydiya tamarta korontada.

Fikradda Bannaanka resonant

The waxyaabaha ugu muhiimsan yihiin inductance resonant circuit (L) iyo capacitance (C). resistor waxay leedahay u janjeera in ay Esplanaden of oscillations, sidaa daraadeed waxa uu ka Bannaanka ka saaraysaa awood. In kasta baadhaya geedi socodka ka dhacda Bannaanka resonant, aan ku meel gaar ah iska indha, laakiin waa in la xusuusnaado in, sida ciidankii reer khilaaf in hababka farsamoyaqaanka, iska caabin korontada ee wareeggeedii aan la suulin karin.

resonance ee voltages resonance iyo hadda

Iyadoo ku xiran habka ay u xira waxyaalaha muhiimka ah ee circuit resonance wuxuu noqon karaa serial iyo isku midka ah. Marka xira circuit taxane resonant in ay signal il danab la soo noqnoqoshada ah ku beegneyd inta jeer ee dabiici ah, xaaladaha qaarkood, waxaa soo baxdo jawaab walwalka. resonance ee circuit korontada ku xiran ee isku midka ah waxyaabaha ay Waxyeelo yeedhay hadda resonance.

inta jeer ee dabiiciga ah Bannaanka resonant

Waxaan ka dhigi kara nidaamka lagu baayici karo ee inta jeer ee dabiiciga ah. Si arrintan loo sameeyo, waa in aad marka hore ka qaadaan capacitor ah, sida ku cad sawirka sare bidixda. Marka taas waxa laga sameeyaa, furaha waxaa loo wareejiyey meel ku cad shaxanka isku on xaq u.

Wakhtigan "0", oo dhan tamarta korontada kaydiyaa capacitor ah, oo hadda ku soo wareegi jiray waa loo siman yahay eber (tiradaasi hoos). Ogsoonow in saxanka top of capacitor waxaa si togan ku amray, iyo hooseysa - taban. Ma arki kartaa oscillations of electrons soo wareegi jiray, laakiin aan u cabbirno kartaa ammeter hadda, iyo oscilloscope si loo raad ku tiirsanaanta oo ka mid ah times hadda. Fiiro T in on our jadwalka - wakhtiga ay ku qaadato inay ku dhameeyaan mid oscillation dhalista injineerinka korontada loo yaqaan "muddada libiqsanayn."

The socodka hadda jihada bilow ah (hoos ka eeg Jaantuska). Energy waxaa laga soo wareejiyay condenser si inductor ah. Ugu jaleecada hore u muuqato mid la yaab leh in inductance waxay siisaa tamar, laakiin waxa ay la mid tahay tamarta ogeed ku jira tiro ka dhaqaaqin.

socodka tamarta lagu celiyaa condenser ah, laakiin la soco in polarity ee capacitor ayaa haatan beddelay. In si kale loo dhigo, saxanka hoose hadda dacwad wanaagsan iyo wasladdii sare - kharash negative (tiradaasi hoos).

Nidaamka waxaa haatan si buuxda u la hadlay, iyo tamarta uu bilaabo inuu soo qulquli ka condenser dib inductance ah (hoos ka eeg Jaantuska). Sidaas darteed, tamarta si buuxda u soo laabtay ilaa barta laga bilaabo iyo diyaar u yahay in la bilaabo wareegga mar kale.

inta jeer oscillation The loo dhawaynayaa karaa sida soo socota:

• F = 1 / 2π (LC) ^0,5,

halkaas oo: F - noqnoqoshada, L - inductance, C - capacitance.

Waxaa loo tixgeliyaa in tusaale ahaan this, geedi socodka ka tarjumaysaa nuxurka jirka ah ee resonance danab.

Baarista resonance danab

In wareeggeedii LC dhab ah mar walba waxaa jira iska caabin yar, taas oo hoos u la wareeg kasta kordhin Ilodanimada hadda. Ka dib markii dhowr wareegyo, hadda waxaa uu hoos ugu eber. saamayn Tan waxa loo yaqaan "Esplanaden of signal sinusoidal". Heerka suuska hadda eber ku xiran tahay iska caabin ah ee Bannaanka. Si kastaba ha ahaatee, iska caabin ah aysan waxba ka beddelin inta jeer ee ay oscillations circuit resonance. Haddii iska caabin ah waa weyn oo ku filan, oscillation a sinusoidal ma dhici doonto at dhan in loop ka.

Sida iska cad, marka ay jirto inta jeer a dabiiciga ah ee oscillation resonance kartaa habka excitation. Waxaan sameynaa tan oo ay ku jiraan in sahayda awood silsilad Daisy ee talantaalli ah ee hadda (AC), sida lagu muujiyey bidixda. Ereyga "variable" waxay muujinaysaa in danab ilaha wax soo saarka ee kala duwan la soo noqnoqoshada gaar ah. Haddii inta jeer il awoodeed oo ay ku beegan tahay inta jeer ee dabiiciga ah Bannaanka, resonance danab baxdo.

Terms of dhacdo

Hadda waxaan ka fiirsan shuruudaha dhacdo of resonance danab. Sida ku cad shaxanka ee la soo dhaafay, waxaan si resistor ku soo wareegi jiray ayuu ka noqday. Iyada oo ma resistor in loop ee hadda ka jirta Bannaanka resonant kordhin doontaa qiimaha ugu badan lagu go'aamiyaa ku soo koobin element circuit iyo korontada. Kordhinta iska caabin ah ee resistor ku soo wareegi jiray resonance ee kordhiyaa u janjeera in ay attenuation ee hadda ku soo wareegi jiray, laakiin wax saameyn ah kuma inta jeer ee vibrations resonance. Sida caadiga ah, hab resonance danab ku ma dhici karto haddii impedance ee circuit resonance ka dhergiyaa R = 2 (L / C) ^0,5.

Isticmaalka voltages resonance for gudbinta radio

ifafaale resonance danab waa arrin cajiib ah jirka ma aha oo kaliya. Waxay kaalin muhiim ah in wireless technology isgaarsiinta - radio, telefishanka, taleefoonka gacanta. Laliska loo isticmaalo gudbinta wireless macluumaadka qasab ku jira circuitry in resonate at inta jeer gaar ah aalad kasta waxaa la yiraahdaa inta jeer side. Iyada oo la adeegsanayo antenna gudbinta xiran gudbiye ah, shanqarta hirarka electromagnetic at inta jeer side.

antenna ee Jidka dhamaadka transceiver kale helo signal oo ku soo koriyo circuit aqbaliddoodii loogu talagalay in lagu resonate at inta jeer side. Waa wax iska cad in antenna helo hannaanka ka mid ah calaamadaha ugu firikuwensiyada kala duwan, oo aan ku xuso qaylada asalka. Sababo la xiriira joogitaanka on qalab aqbaliddoodii soco wixii soo noqnoqoshada side Bannaanka resonant ah, aqbalana kaliya doorteen inta jeer ee saxda ah, dabaqii labaad oo dhan aan loo baahnayn.

Ka dib markii lagu ogaan karo Ilodanimada inayan meyxaanahaa (AM) radio, signal a noqnoqoshada hooseeyo quduuska Xaggeeda (LF) waxaa maqalka iyo quudin jiray in ay qalabka dhawaaqa soo saara ah. Tani waa qaab fudud ee radio waa mid aad u xasaasi u ah qaylada iyo faragelinta.

Si loo hagaajiyo tayada macluumaadka helay horumariyo oo si guul leh loo isticmaali kale, siyaabo badan oo horumarsan ee gudbinta radio, kaas oo sidoo kale ku salaysan isticmaalka nidaamka resonant soco.

isbedbeddelka Frequency iyo FM-radio furfuraya badan oo dhibaato la Ilodanimada meyxaanahaa signal gudbinta radio, laakiin at kharashka nidaamka gudbinta kakanaanta weyn. nidaamka FM-radio dhawaaqa elektaroonig mareenka waxaa beddelay isbedel yar oo soo noq side. Piece of qalab ah oo u qabata diinta this waxaa lagu magacaabaa "modulator" waxaa loo isticmaalaa la gudbiye ah.

Iyadoo la raacayo, aqbalana waa in lagu daraa demodulator ah diinta signal u jajabiyaa qaab ah in la soo saari karaa iyada oo uu samaacad ka dib.

Tusaalayaasha kale isticmaali resonance danab a

voltages resonance sida mabda'a aasaasiga ah waxaa sidoo kale lagu daro in circuitry ee filtarrada badan, hubkaas ayaa loo isticmaalaa in injineernimada korontada si loo baabi'iyo ku calaamadaha waxyeello iyo rabin, iyo yeeesha pulsation ee guud ahaan calaamadaha sinusoidal.
