Resonance stress. He aha resonance huakai kaapuni

Resonance o kekahi o ka loa, he pono ole ma ke ano maoli, physicalʻike manaʻo. Ke kŰia o ka resonance hiki ke malama i ka ma paʻi, uila, a hiki thermal nenoai. Me ka resonance, i ole i mākou i ka Radio, kīwī, mele, a hiki heleuma ma ka peku,ʻaʻole e hōʻike ka hoʻokō PalekanaEND_LINK nenoai hoʻohana i loko o kēia lāʻau lapaʻau. Kekahi o ka loa a me ka hoihoi 'mau mea kōkua ma ke ano o ka resonance huakai kaapuni a mea he resonance anakahi uila.

Na oihana mua o ka resonant huakai kaapuni

Resonance kānāwai i loko o ka ai-kapaia RLC-i puhi ai, ec ka i kēia eiiiiiaiou:

• R - resistors. Mau manao maalea e pili pū ana i ka ai-kapaia hana oihana mua o ka pou kaapuni, uila ikehu ua hoohuliia i loko o ka wela. Ma na olelo e ae, e wehe i ka mana mai ka huakai kaapuni a hoohuli ia i loko o ka wela.
• L - inductance. Inductance i pou i puhi ai - Analog o ka nuipa a 'oni' i me mechanical nenoai. Kēia ke keʻena mea,ʻaʻole loa kekahi 'i loko o ka huakai kaapuni a oe e ho'āʻo e hana ia i loko o kekahi loli. Ma mechanics, no kekahi laʻana, e like me ka loli o ka loli ma ka māmā holo. Ka uila kaapuni - kaʻikena loli. Inā ka mea, no kekahi kumu i, ka inductance counteracts ka huakai kaapuni a? Eia loli.
• C - inoa no capacitors, i nā mea maalea, e hoahu uila ikehu, e like me ka pūnāwai aua me mechanical ikehu. Inductance noʻonoʻo a me nā hale kūʻaiʻume mākenēki ikehu, oiai noʻonoʻo i ka mea pihana malama, a pela hale kūʻai i ka pila nui ikehu.

I ka manaʻo o ka resonant huakai kaapuni

Ke ki oihana mua i resonant kaapuni inductance (L) a me ka capacitance (C). Ka mea pale mū holapū i ka welelau o ka damping o oscillations, no laila, e lawe aku oe i ka mana, mai ka huakai kaapuni. Ma ka nana i ka keʻano o ka hanaʻana 'ia i loko o ka resonant kaapuni, ua hulina i kāpae'ōlelo, akā, e pono e hoʻomanaʻo ia, e like me ka mana o ke kū'ē ma ÿano nenoai, uila ia'ku ma na wahi i puhi ai hiki ole ke eliminated.

Ke resonance o resonance voltages, a paialewa

Ke kaumaha ma muli o ka ano o ka ai pili aku i ke kī oihana mua o ka resonance huakai kaapuni hiki e pūkaʻina a me ka laua. I ka ai pili aku i ka hopena ua resonant kaapuni ana i ke anakahi uila kahi neaiaea me ke alapine (frequency) coinciding me ke alapine (frequency) maoli, ma lalo o kekahi rula, me he ala i ka stress pane. Ke resonance i loko o ka pou kaapuni pili ma laua me ke kū'ē hehee wale kapa resonance paialewa.

Ka maoli alapine (frequency) o ka resonant huakai kaapuni

Mākou hiki i ka'ōnaehana i oscillate ma ka kūlohelohe alapine (frequency). E hana i kēia, e pono mua e kauoha aku i ka mea pihana, e like me ka hoike ana i loko o ka luna kiʻi ma ka hema. A pau keia ua hana, ka ki ua hoololiia a hiki i ke kulana i hoikeia ma ka ia huahelu ma ka akau.

I manawa "0", a pau na pou ikehu waiho i loko o ka mea pihana, a me ka pono ma ka huakai kaapuni mea like i Aʻohe (huahelu ma lalo nei). E noke i ka luna papa o ka mea pihana ua ikaika i hoopiiia, a me ka lalo - i loko o ka io. Mākou ke ole ike i ka oscillations o electrons i loko o ka huakai kaapuni, akā, ua hiki anaʻikena ammeter, a me ka oscilloscope e kumumea i ke kaukaʻi o kaʻikena manawa. E noke i T ma luna o mākou haʻalele 'ana - i ka manawa e lawe ai i ke hoʻokō' ia i kekahi oscillation kona hanau ana i ka uila 'enekinia, i kapaia o "ka hoʻokūoʻo au."

Ke papa lua i pele i loko o ka clockwise ala (nānā i ke Kii ma lalo nei). Energy ua hoololiia mai ka condenser a hiki i ka inductor. Ma mua kilohi ia e he malihini i ka inductance hoʻolako ikehu, akā, ia mea i 'ano like me ka kinetic ikehu he i loko o ka neʻe maila nuipa a.

Ka pele o ka ikehu ua hoi aku la i ka condenser, akā, e hoailona oukou i ka polarity o ka mea pihana i manawa loli. Ma nā hua'ōlelo, ka lalo papa manawa mai i ka maikaʻiʻoihana, a me ka hoaka o ka papa - io kauoha (huahelu ma lalo nei).

Ka'ōnaehana ua manawa maopopo'ōlelo, a me ka ikehu hoʻomaka e kahe mai ka condenser hoʻi i ka inductance (nānā i ke Kii ma lalo nei). E like me ka hopena, ikehu Ua pau loa hoʻi i kona ho omaka, a mea makaukau e hoʻomaka i ka pōʻaiapuni hou.

Ke oscillation alapine (frequency) hiki ke He kokekau wale nō like penei:

• F = 1 / 2π (LC) ^0,5,

kahi: F - alapine (frequency), L - inductance, C - capacitance.

Noonoo ana ma keia hana, ke kaʻina Hōʻike 'ka physical i loko o ke anakahi uila resonance.

Hoʻokolokolo 'ana anakahi uila resonance

Ma maoli LC wahi i puhi ai he mea mau he hōʻemi iki ia'ku i emi me kēlā me kēia pōʻaiapuni hoʻonui i kaʻikena ikaika hawewe. Ma hope o kekahi mau pōʻaiapuni, ua hoemiia kaʻikena i Aʻohe. Ua kapaʻia kēia hopena "damping o sinusoidal neaiaea". I ka uku o kaʻikena palaho i Aʻohe hilinaʻi nui ma luna o ka ia'ku i loko o ka huakai kaapuni. Naʻe, ka mea e kū'ē'ē mai 'aʻole e hoʻololi i ka alapine (frequency) o ka resonance huakai kaapuni oscillations. Inā ka ia'ku Ua nui lawa,ʻaʻole he sinusoidal oscillation, e hana i nā mea a pau i loko o ka loop.

ʻae nō hoʻi, ma laila mea he alapine (frequency) maoli o ka oscillation hiki resonance excitation kaʻina. Mākou hana i kēia ma ka a me loko o ka daisy kaulahao mana lako o alternatingʻikena (AC), i hoikeia ma ka hema. Kaʻia "ee iaaanu aey" Hōʻike i ke kumu ia auoiaea anakahi uila loli aʻe me ka kekahi alapine (frequency). Inā coincides ka mana kumu alapine (frequency) me ke alapine (frequency) maoli o ka huakai kaapuni, anakahi uila resonance aicieeaao.

Ma muli o ka hanana

Ano, ke noonoo i ka olelo o ka hanana o ke anakahi uila resonance. E like me ka hoike ana ma ka hope huahelu, hoi aku mākou i ka mea pale mū holapū i loko o ka huakai kaapuni. Meʻaʻohe mea pale mū holapū i loko o kaʻikena loop i loko o ka resonant kaapuni, e mahuahua i kekahi i kā mākou waiwai hoʻoholo ma ka huakai kaapuni hehee ai kiko'î a me ka mana lako. Mahuahua ka ia'ku o ka mea pale mū holapū i loko o ka resonance huakai kaapuni maoli i ka welelau o i ka attenuation o ka pono ma ka huakai kaapuni, akā, 'aʻole e pili i ke alapine (frequency) o ke resonance kuekueni. Nō kāu, ke anakahi uila resonance pololei 'aʻole i ana ina ka impedance o ka resonance huakai kaapuni satisfies = 2 (L / C) ^{0,5 R.}

E ho ohana i resonance voltages no ka Radio EYI

Anakahi uila resonance kŰia mea,ʻaʻole wale nō ke hoʻoponopono 'ike kŰia. Ua Radio Heʻano nui kūlana ma ka palapala 'enehana nā pūnaewele - Hoʻi Hou, kīwī, ke kelepona hele telephony. Transmitters hoʻohana no nā pūnaewele EYI o ka 'ike pono no circuitry e resonate ma kekahi mau' alapine (frequency) no kēlā me kēia mea ua kapaia lawe alapine (frequency). Ma keʻano o ka pū i hiki kukuna pili i ka lēkio leo, e kī ana electromagnetic a ka nalu i ka lawe alapine (frequency).

Ke kukuna i ka 'ē aʻe hopena transceiver ala hookipa i ka peahi ana mai, a hoʻopakele ia i ka loaa kaapuni ke hoʻololi e resonate ma ka lawe alapine (frequency). Ka mea, ua maopopo i ke kukuna hookipa mai i ka ai iiiaanoaa o nā lepa ma kekahi nä alapine,ʻaʻole e hōʻike i ke kāʻei kua leo. Aie i ke alo ma ka loaa ana na mea maalea, pila hāpa e ai i ka lawe alapine (frequency) o ka resonant huakai kaapuni, i ka pa alima Nāna e koho wale i ka pololei alapine, kānana mai a pau ole.

Ma hope o kaʻimiʻana i ka ikaika hawewe pē (AM) Radio, he mea laʻa haʻahaʻa alapine (frequency) neaiaea mau mea (LF) ua listen, a hanai aku la ia i ka leo hua noonoo. 'O kēia ka simplest ano o ka Radio ka loa ikepili koʻikoʻi i ka leo a me ka' ākeʻakeʻa.

E hoʻoikaika i ka pono o ka mea i loaa mai 'ike ke kino, a ana' ē aʻe, oi holomua aoao o ka Radio EYI, i ua i ka nānā 'ana ma o ka hoʻohana' ana o ka pila hāpa e resonant nenoai i hoʻohana.

Frequency modulation a me ka FM-Radio Wehewehe i nā mea he nui o na pilikia a me Radio pū i hiki ikaika hawewe pē neaiae, akā, ma ka lilo o ka nui ka manaʻo pohihihi EYI nenoaiu. Ke FM-Radio'ōnaehana kani electronically'āpana e hoohuliia mai i loko o loli liʻiliʻi ma ka lawe alapine (frequency). Apana o ka lako a pan i hanaʻia i kēia huli ana ua kapaʻia he "modulator" ua hoʻohana 'ia me ka lēkio leo.

Alaila, o ka pa alima pono e hou i ka demodulator no ka hoʻololi 'ana i ka hōʻailona hoʻi i loko o ka palapala ana e paʻi hiki ma ka loudspeaker.

Other examples hoʻohana i ke anakahi uila resonance

Resonance voltages like me ka kahua rula ua i hoohui ia ma ka circuitry o mau kānana, e hoʻomano hoʻohana i ka uila 'enekinia, e hoʻopau i ka palapala a me ka hua'ōlelo i makemake no lepa, a smoothing ka pulsation hoʻomakaʻia sinusoidal lepa.
