Resonance kushushikana. What resonance redunhu

Resonance imwe rakajairika zvakasikwa, panyama mananara. Chiitiko pamusoro resonance kunogona kuonekwa mune zvokuimba, zvemagetsi uye kunyange chafariz nehurongwa. Pasina resonance, isu tisina redhiyo, terevhizheni, mimhanzi uye kunyange Anoita panguva playground, tisingatauri chinobudirira chirwere gadziriro inoshandiswa mukurapa ano. Chimwe chezvinhu zvinofadza uye anobatsira mhando resonance redunhu chinhu resonance voltage.

Pezvokuvamba resonant redunhu

Resonance zvingaitika mune dzinonzi RLC-mumatunhu kuitika zvinotevera zvinoriumba:

• R - resistors. mano izvi chokuita inonzi vanoshingaira zvinhu zvemagetsi redunhu, zvemagetsi simba iri dzikwanise kupisa. Nemamwe mashoko, ivo kubvisa simba kubva redunhu uye kuichinja kupisa.
• L - inductance. Inductance mu nemagetsi nematunhu - analog nevazhinji kana inertia mune zvokuimba gadziriro. chikamu ichi hachisi chaizvo kuoneka mudunhu kusvikira ukaedza kuzviita shanduko chero. In hurongwa Somuenzaniso, kuchinja kwakadaro kuchinja velocity. The yemagetsi wedunhu - kuchinja ano. Kana kuti zvimwe chikonzero zvaitika, inductance anofumura kwakadaro redunhu utongi shanduko.
• C - nan'anuro capacitors, izvo namano kuti kuchengeta magetsi simba, sezvakanga chitubu vanochengeta zvokuimba simba. Inductance inonyanya uye zvitoro rinobva simba, nepo capacitor mutariri inonyanya uye nokudaro rinochengeta yemagetsi simba.

Pfungwa yacho resonant redunhu

The zvinokosha zviri resonant wedunhu inductance (L) uye capacitance (C). The resistor iine katsika damping pamusoro oscillations, saka anobvisa simba kubva remudunhu. In taongorora kwemasayendisiti kuitika resonant remudunhu, isu chakamboti hanya, asi zvinofanira kuyeukwa kuti, kufanana simba kukweshera mune zvokuimba gadziriro, zvemagetsi kurwisa mumatunhu hazvigoni kubviswa.

The resonance pamusoro resonance voltages uye dzenzvimbo

Zvichienderana nzira unobva zvinokosha zvenyaya resonance redunhu kunogona Serial uye zvakafanana. Apo unobva akatevedzana resonant wedunhu kuti voltage kunobva Mureza ane kakawanda coinciding ane dzinongoitika kakawanda, pasi zvimwe zvinhu, pane kuchimuka kunetseka apindure. The resonance ari zvemagetsi wedunhu kwakabatana munguva zvakafanana nemashoko reactive zvinhu anonzi resonance dzenzvimbo.

The kwomuzvarirwo kakawanda pakati resonant redunhu

Tinogona kuti anyatsoita oscillate panguva dzinongoitika maitikiro. Kuti aite izvi, unofanira kutanga undoraira capacitor, sezvinoratidzwa pamusoro mufananidzo kuruboshwe. Kana izvi zvaitwa, kiyi iri zvaitambidzwa nzvimbo inoratidzwa chete mufananidzo kurudyi.

Panguva "0", zvose zvemagetsi simba anochengeterwa capacitor, uye magetsi mudunhu akaenzana razero (mufananidzo pazasi). Cherechedza kuti pamusoro bwendefa capacitor iri chokwadi mhosva, uye nechepasi - iri kunaka. Hatigoni kuona oscillations pakati maerekitironi mudunhu, asi tinogona kuyera kuitika ammeter, uye pamwe oscilloscope kuti kuronda ari kuvimba zviri kuitika nguva. Cherechedza kuti T iri purogiramu yedu - nguva zvinotora kupedza imwe oscillation rinobereka mune zvemagetsi ouinjiniya inonzi "kuzengurira nguva."

The kuitika Rwako ari Kutenderera divi (ona Figure pazasi). Energy iri kubva kuna condenser kusvikira kune inductor. Pakutanga zvingaita sezvinoshamisa kuti inductance kunopa simba, asi zviri zvakafanana kinetic simba huri zvinofamba vakawanda.

Aibuda simba iri vakadzokera condenser, asi cherechedza kuti polarity yacho capacitor zvino achinja. Nemamwe mashoko, Musana ndiro zvino ane mafungire mutariri uye yokumusoro mundiro - kunaka mutariri (mufananidzo pazasi).

The Hurongwa zvino yakanyorerwa zvakazara, uye simba inotanga ichiyerera ichibva condenser kudzokera inductance (ona Figure pazasi). Somugumisiro, simba iri zvachose shure kwarinovirira pokutangira uye akagadzirira kutanga kutenderera patsva.

The oscillation maitikiro inogona approximated sezvinotevera:

• F = 1 / 2π (LC) ^0,5,

apo: F - kakawanda, L - inductance, C - capacitance.

Ngarira muenzaniso uyu, kwacho kunoratidza musimboti voltage resonance chaiko.

Tsvangurudza voltage resonance

In chaiyo LC nematunhu pane nguva dzose zvishomanana nemishonga iyo zvinoderedza nomumwe kutenderera kuwedzera kuitika amplitude. Mushure zvinogara anoverengeka, magetsi ipfupi kuti razero. Izvi anonzi "damping pamusoro sinusoidal Mureza". Mwero kuora kuitika kune razero kunobva mumweya kutenderera. Zvisinei, kuzvidzivirira haachinji kakawanda pamusoro resonance redunhu oscillations. Kana kurwisa iri yakakura zvakakwana, munhu sinusoidal oscillation hazvizoitiki zvachose muna loop.

Zviri pachena, apo pane zvakasikwa kakawanda oscillation anogona resonance excitation rikurumidze. Tinoita izvi kusanganisira ari the daisy Chain simba nerubatsiro kuti rakatumbuka kuitika (AC), sezvinoratidzwa kuruboshwe. Shoko rokuti "shanduka" rinoratidza kuti kunobva goho voltage kunosiyana-siyana neumwe maitikiro. Kana simba panobva kakawanda rinobatana chaiwo kakawanda mudunhu, voltage resonance unomuka.

Terms of chiitiko

Zvino isu funga mamiriro ezvinhu panowanikwa voltage resonance. Sezvinoratidzwa okupedzisira mufananidzo, takadzokera resistor mudunhu. With hapana resistor iri kuitika loop iri resonant wedunhu kuchawedzera kuti vaifanira ukoshi pakutsvaga redunhu chinhu parameters uye simba zvitengeswa. Kuwedzera kurwisa zviri resistor iri resonance redunhu kunowedzera katsika kuti attenuation zviri kuitika mudunhu, asi asingaiti kukanganisa kakawanda resonance vibrations. Kazhinji, asi voltage resonance muoti hariwanikwi kana impedance pamusoro resonance redunhu zvinogutsa R = 2 (L / C) ^0,5.

Kushandisa resonance voltages kuti nhepfenyuro yedzimudzangara

Voltage resonance Fani muviri kuziva chakajairika kwete chete. It anobatsira inokosha basa Wireless kukurukurirana zvemichina - redhiyo, terevhizheni, cellular nvidia. Zvinotakura anoshandiswa Wireless hutachiwana mashoko hazvo dzine hushande kuti anoshandawo pane imwe kakawanda kuti mudziyo mumwe nomumwe unonzi keriya maitikiro. Kuburikidza achitumira kanyanga chokuita kuti wokutepfenyurisa, izvozvo inongorira remagetsi mafungu panguva mutakuri maitikiro.

The kanyanga pane mumwe mugumo transceiver nzira anogamuchira chiratidzo uye anonunura nayo kugamuchirwa redunhu chakagadzirirwa anoshandawo panguva mutakuri maitikiro. Zviri pachena kuti kanyanga anogamuchira muzvizhinji kuti anonongedzera panguva frequencies dzakasiyana, tisingatauri necheseri ruzha. Nokuda kuvapo ari kugamuchirwa mudziyo kuti zvirire mutakuri kakawanda pakati resonant redunhu, mugamuchiri chete anosarudza zvakarurama kakawanda, inonzwika apo zvose basa.

Mushure Detective ari amplitude modulated (AM) redhiyo, akazvitsaurira pasi Frequency chiratidzo kwazviri (LF) iri yakakura uye zvokudya inzwi zvibereko mudziyo. Ndicho nyore chimiro redhiyo zvikuru nehanya ruzha uye kukanganiswa.

Kuvandudza of vakagamuchira mashoko dzakabudirira uye zvinobudirira vakashandisa vamwe, zvikuru yepamusoro nzira redhiyo yedzimudzangara, rinova kwakavakirwa kushandiswa zvirire resonant gadziriro.

Frequency vachisiyanisa inzwi uye FM-redhiyo anogadziriswa zvinetso zvakawanda pamwe redhiyo achitumira amplitude modulated chiratidzo, asi vachikanganisa kuchikosha kunzwisisa hutachiwana hurongwa. The FM-redhiyo hurongwa rinonzwika mukombiyuta turakiti vari dzikwanise kuchinja vaduku keriya maitikiro. Piece midziyo kuti anoita kutendeuka ichi anonzi "modulator" rinoshandiswa pamwe wokutepfenyurisa.

Saizvozvowo, mugamuchiri inofanira kuwedzerwa kuti demodulator nokuda unoponesa Mureza shure muchimiro chinogona kuburitswa kubudikidza gudzanzwi.

Mimwe mienzaniso kushandisa voltage resonance

Resonance voltages sezvo chinokosha iri vaumbe mune hushande siyana filters, vari zvinowanzoshandiswa zvemagetsi ouinjiniya kubvisa inokuvadza uye vasingadiwi anonongedzera, uye rimire pamusoro pulsation generating sinusoidal anonongedzera.
