Indlela yokuqhuba ishishini pendulum - esasidla oscillation

Parameters yeenkqubo oscillatory kukho izinto eziphathekayo ezaziwayo-kakuhle - le awo kunye nexesha. Ngenxa yoko, phantsi intlokoma bayaqonda komthetho ezininzi ngamaxesha ngokuphinda inkqubo yokutshintsha wobungakanani wezandla ixabiso layo kakubi okanye zero. Makhe sicinge ukuba lo mthetho inophawu sinusoidal. Ngoko ke, ukuba umsebenzi F (x) le nkqubo inikwe ngokohlobo F (x) = K * isono (x), kufuneka nje msebenzi jinga, leyo, khumbula, phezulu nasezantsi, phantsi naphezulu ...

Cinga igrafu uthe umsebenzi othile, umgaqo, naliphi na ixabiso kwi esqwini Y zibonakaliswe y1, kwaye zihamba X axis, y2 ufumane ingongoma elandelayo ezixabisa y1. Ngoku, ukuba X-axis, ukusuka v2 kuyo, angacela ukuba ilingana intavali T = (y2 - y1), sifumana v3 point kwaye iya kulingana y1 kunye y2. Imilo ye igrafu phakathi kwezi ngongoma ngqo ngokuphindaphindiweyo kuwo onke amacandelo ezilandelayo Ndikulinganise T. Ngaloo ndlela siye safumana T parameter ukuba inkqubo echazwe yi kwifomula F (x) = K * isono (x), nto leyo eye ipropati emangalisayo leyo etshintsha ngaphakathi ingxabano X T ikhokelele utshintsho umsebenzi F (x) kulo lonke uluhlu lwamaxabiso zayo. Ngenxa yokuba utshintsho kwi X-axis alipheli ekuhambeni kwexesha, ngamanye amazwi, inani lemijikelo T ngamabona ezininzi, ngoko sibe nokungazinzi koqoqosho, ie Ndiyaphinda, ukutshintsha umsebenzi. ixesha Cycle T ibizwa ngokuba ixesha oscillation kwaye ulinganiswa kwimizuzwana. Kodwa wavuma ngaphezulu kwimizobo ukusebenzisa iyunithi yokulinganisa, ekuthiwa amaza oscillation, zibonakaliswe f kwaye computes f = 1 / T, iyunithi ibizwa ngokuba Hertz (Hz). Ukuphinda-phinda 1 Hz - na oscillation enye ngomzuzwana.

Singqongwe lihlabathi 'ephindwe ". Eguquguqukayo - ikhala, umsinga ngumbane oogesi, indlela ukungcangcazela, ukukhanya, namanzi, njengokujikeleza iiplanethi, kwaye ... musa ndizibalela phakathi, ezi intlokoma. Bonke bephela imida eyaneleyo eqhelekileyo zobungakanani yabo, bathi, "uluhlu yokwahluka." Umzekelo, nezihlandlo oscillation ezitsho isandi oluvakalayo umntu - ukususela 16 Hz 20 kHz (1 kHz = 1000 Hz), kunye noluhlu ezitsho yesandi ekudla ngokuba ilele kuluhlu 100 - 4000 Hz. Kuyinto eyaziwayo ukuba bonke abantu kuva lonke uluhlu izandi - ezininzi sele 12-15 kHz lalela. Le ndlela isebenza intlokoma cuke 100, 200 kHz nangaphezulu. Iinkcukacha iindlela kwakhona ukutshintshatshintsha uluhlu enkulu ezitsho - wabelane Hz kunye amashumi kHz. Kodwa ke uninzi uluhlu olubanzi amaza - zezabelo kunye ukuya kumawaka amaninzi kwezigidi Hz. Kule spectrum kwihlabathi amaza okukhanya yomhlaba oluncinane kakhulu, kodwa ukuba yokuba ziqondeka zethu amaziko umbono. Ezahlukeneyo oscillation frequency kwi lwaseNtshona Koloni ziba amaza okukhanya limisa umbala bokukhanya - obomvu purple.

Kodwa emva "omnye isikwere." Amaxesha amaninzi, iluncedo ukusebenzisa iiyunithi iguqulwe kancinane. artifice okunjalo kwenza ukuba kube lula ezininzi iifomyula ze uzenze zibonakale ngaphezulu. Kwaye oku ngenxa yokuba ukuba imisebenzi oscillation sinusoidal kubonisa ithuba ukusebenzisa variables ngeeyunithi zemilinganiselo ye engile - eziqala okanye izidanga. Kodwa kwangaxeshanye, xa kubalwa "aqala" sihlale 2p, leyo, kunye rhoqo afumaneka kwi amabinzana amaninzi zezibalo. Ngoko bagqiba ukuqalisa iyunithi basis of yokulinganisa kwamaza, wayinika igama "oscillation elibujikele rhoqo." Undoqo kule yunithi kukuba frequency kwayo elicetyiweyo inani oscillations ngo-2 imizuzwana * π, ngamanye 6.28 umzuzwana. frequency Zijika ibalwa kwifomula ω = 2 * π * f. Besive amaza elibujikele kubonakaliswa iyunithi layo yomlinganiselo - kwisangqa ngomzuzu.

inkqubo jinga uye zisekhona parameters okuluphawu ubuntu bakhe. Thatha pendulum wethu olungileyo ubudala yaye amisiweyo kancinane, ukunciphisa yona imo inkqubo ukungcangcazela - tick-tock, phawula-tock. Ukwenza oku kanye kwanele ukuba akathi kwaye ... usele yedwa. Oko siza kubona? A pendulum oscillates elide ngokwaneleyo ngaphandle nasiphi na isicelo olongezelelweyo amandla, rhoqo yayo oscillation ayitshintshi, kwaye awo kunciphisa ngcembe, ngenxa yokuba imikhosi zochuku ngamayelenqe kanye. okunzulu xa ekuqaliseni emva enotyhalo yentlangano pendulum, okanye nayiphi na inkqubo lokungcangcazela umiselwa kuphela parameters, wabiza abakhe. Xa sicingela ukuba imikhosi ngexesha elifanayo ukuyeka ayalingana zero, kwaye ilula kakhulu - zonke ezandleni zethu, pendulum enjalo, ubizwa ngokuba zemathematika, uya oscillate ngonaphakade, kwaye ixesha oscillation kungaba ibalwe ukusuka eyaziwayo, leyo sele Classic, ifomula - C = 2 * π * √ l / g.

Ukusuka analysis sinako ukwenza isigqibo esibalulekileyo: nezihlandlo endalo oscillation ye kuqala ixhomekeke kuphela lwangaphakathi parameters kwenkqubo - ubude womsonto ubukhulu yokunyusa womxhuzulane yomhlaba.
