Hadda maxay resonance

Marka waxbarashada asaaska korontada ka mid marxaladda hadda resonance daruuri ka fiirsaday iyo voltages. ifafaale Kuwani waa asalka ah ee wareeggeedii AC iyo wuxuu noqon karaa mid aan loo baahnayn iyaga oo u baahan tixgeliyaan jilitaanka iyo awood xidhiidh ah wareeggeedii oo waxtar leh.

Tusaale ahaan, resonance ku soo wareegi jiray AC waxaa inta badan loo isticmaalaa in radio: soco circuit oscillation ku salaysan danab resonance ah, waxay u saamaxdaa dhowr jeer si ay u xoojin signal raadiyaha awood yar yahay, tan iyo markii ay sabab u tahay isbadal "capacitance-inductance" waa koritaanka qiimaha stress wax ku ool ah.

Ayaa sheegay in circuit oscillation - aasaas u ah fahamka stress (ama) sida hadda resonance iyo. Waa circuit xidhan korontada ka kooban capacitor ah oo ku xiran in isku midka ah (taangiga C) iyo coil ah (L inductance). In iyaga habka of "liso" tamarta ee capacitance duurka oo korontada ah oo duurka ku magnetic waxaa jira inductance is-deminta (sabab u ah joogitaanka R ka qayb resistive) isbedbedelka ah inta jeer cayiman.

In resonant hab circuit iska caabin marinkii qayb hadda firfircoon wakiil R. Waxaa jira resonance kaliya ee hadda iyo danab resonance ah. Tixgeli Tilmaamo ay.

Resonance hadda dhacdaa circuit ee barbar capacitor ku wareegay iyo gariiradda, oo ratings lagu doorto si hadda ee C iyo L waa hadda. Sidaas darteed of «Champions League» qiimaha hadda ku soo wareegi jiray ee uu ka badan yahay silsilad total.

Mabda'a hawlgalka waa sida soo socota: at kor xoog, condenser raasamaal amarka (in danab a sahayda magacaaban). ka dib, waxaa ku filan in ay ka jari isha iyo buuxi circuit si wareeg ah si loo bilaabo nidaamka of dheecaan in gariiradda. maraayay hadda ma dhex abuuraa beer magnetic iyo abuuraa ciidamada is-induction electromotive, hadda oppositely faray. Its qiimaha ugu badan waxaa la gaaray waqtiga dheecaan dhamaystiran oo capacitor ah. Iyadoo la raacayo, taas macnaheedu waa in awoodda oo dhan tamarta ururtay oo duurka ku magnetic waxaa loo bedelay inductance. Si kastaba ha ahaatee, ay sabab u tahay is-induction mooshin gariiradda qayb eedeeyay la joojiyo.

Tan iyo counterflow ka capacitor leh mar dambe la (isagu waa daallan), waxa uu bilaabo inuu dhici buuxin, laakiin polarity a kala duwan. Sidaas darteed, dhammaan gariiradda beerta waa diinta ka qaadaan ka capacitor soona celin geedi socodka. Sababo la xiriira joogitaanka gudaha R qayb resistive qaadataa meel si tartiib tartiib ah engegay isbedbedelka. Sayidka, resonance hadda waxaa la sameeyaa.

stress resonance dhacdaa xiriir taxane ah R resistor, L gariiradda iyo capacitor a C. An ku feature muhiim u tahay xaqiiqda ah in danab korontada waa ka hooseeyaa ee capacitor iyo gariiradda (at element kasta si gooni gooni ah), laakiin hadda siman la hayo. Waxaa intaa dheer, ee danab iyo hadda ku jiraan xaalad. Xaaladda ugu weyn ee ka bixitaanka iyo dayactirka habka this - sinaanta ee reactance yeelista iyo capacitive. Iyadoo la raacayo, impedance la ogaaday in ay si firfircoon.

Si loo go'aamiyo qiimaha ku ool ah oo danab guud gariiradda iyo capacitor waxaa loo isticmaalaa sharciga Ohm ee. Xaaladdan oo kale waa loo siman yahay si wax soo saarka ah ee hadda gariiradda reactance u yeelista (U1 = IX1). Iyadoo la raacayo, ee hadda ee capacitor waa loo laablaabi by capacitance ah (U2 = IX2). Tan iyo in taxane la xiriira xubno ka hadda waa, iyo X1 resonance = danab X2 guud inductance iyo capacitance waa u siman yihiin. Sidaa awgeed, la kordhiyo qaybaha Waxyeelo, waxaadna ku gaari kartaa koror weyn oo U1 danab iyo U2, iyadoo la sii qiimaha joogta ah isha EMF ah. meesha ugu weyn ee codsiga - injineernimada radio a.
