Kaxaynta pendulum - inta jeer ee oscillation

Beegyada uu u ah hababka oscillatory yihiin fikradaha jirka si fiican u yaqaan - the Ilodanimada inayan iyo muddo. Sidaas darteed, hoos vibrations ogayn sharciga badan wareegsan by cel-socodka ah ee la beddelo tirada jirka ku wareegsan qiimaha celceliska ah ama eber. Ina keena aynu ka fikirno in sharcigan uu leeyahay dabeecad sinusoidal. Sidaas daraaddeed, haddii F shaqada (x) ee habka la siiyo by nooca F (x) = K * dembiga (x), waxaan leenahay sida function kaliya ah oscillating, kaas oo, soo xusuuso, kor iyo hoos, kor iyo hoos ...

Tixgeli garaafka fansaarka sheegay of a, in mabda, qiimaha wax ku dhidibka Y muujinaysaa Y1, iyo dhaqaaqin taxey X u, Y2 heli dhibic soo socda la qiimo ah Y1. Haddaba, haddii-dhidibka X, ka v2 barta, raagin bareeg loo siman yahay T = (Y2 - Y1), waxaan ka heli v3 dhibic iyo waxa ay noqon doontaa si siman u Y1 iyo Y2. Qaabka uu garaaf u dhexeeya dhibcood, kuwaas oo si sax ah soo noqnoqda on dhammaan qaybaha xiga simanyihiin T. saasaanu kugu soo helay T dhimaya tahay geeddi-socodka lagu tilmaamay by caanaha a F (x) = K * dembiga (x), taas oo uu leeyahay hantida cajiib ah in ay isbedesho gudahood Xujada X T hogaanka inay isbeddel ku shaqo F (x) u sarreeyey kala duwan oo dhan qiyamkiisa. Maxaa yeelay isbedel ku-dhidibka X waa aan xad lahayn in waqti, si kale loo dhigo, tirada wareegyada T Rowan badan, ka dibna waxaan ku leeyihiin meerto, ie Waxaan ku celinayaa, isbeddel ah ee shaqada. waqti Cycle T la odhan jiray muddo of oscillation iyo waxa lagu qiyaasaa in ilbiriqsi. Laakiin dheeraad ah oo aqbalay in farshaxanka si ay u isticmaalaan qaybta cabiraada, oo la odhan jiray inta jeer oscillation ah, muujinaysaa f iyo computes f = 1 / T, unit ah waxa la yidhaahdaa waa Hertz (Hz). Inta jeer ee 1 Hz - waa mid ka mid oscillation per labaad.

Waxaan ku hareereysan dunida "dhacdhaco". Isbedbedelka - waxaa codadka, koronto ee silig ka, hab gariirka, nuurka, baddu ah, wareeg ee quraxda xidiga ah, iyo ... ha tiriyo mid ah, kuwaas oo gariirka. Dhamaan iyaga ka mid ah waxay leeyihiin xuduudaha caadiga ah oo ku filan oo ka mid ah inta jeer, waxay yiraahdaan "kala duwan oo ka mid ah kala duwanaansho." Tusaale ahaan, inta jeer oscillation ee la maqli karo qof mawjadaha dhawaaqa - 16 Hz 20 Khz (1 Khz = 1000 Hz), iyo duwan ee mawjadaha dhawaaqa colloquially been kala duwan oo 100 ka - 4000 Hz. xaqiiqda A si fiican u yaqaan in dadka oo dhan ma maqlaan tiro badan oo ah codadka - badan oo hore u 12-15 sawaxan dheer Khz. farsamada wuxuu khuseeyaa ku vibrations ultrasonic 100, 200 Khz iyo wixii ka sareeya. hababka Details sidoo kale is beddelid laga yaabaa in tiro balaadhan oo ah mawjadaha - iyo wadaagaan Hz iyo tobanaan Khz. Laakiin inta badan waxay leeyihiin tiro balaadhan oo ah hirarka electromagnetic - ka saamiyada iyo ilaa kumanyaalka kun ee reer malaayiin Hz. In spectrum caalamiga ah ee hirarka iftiinka dalka waa mid aad u yar, laakiin in ay garteen by our xubnaha aragga. inta jeer oscillation kala duwan ee spectrum ee hirarka iftiinka go'aamiyo midabka ah ee iftiinka arki karo - ka cas guduud.

Laakiin back to "mid ka mid ah laba jibbaaran." Inta badan, waa habboon in la isticmaalo a unugyo yar modified. artifice noocan oo kale ah u ogolaanaya in ay fududeeyaan badan oo qaaciidooyinka iyo dhigo kuwo la arki karo. Markaasaa waxaa taas waxaa sabab u ah xaqiiqada ah in hawlaha oscillation sinusoidal soo jeedinaya macquul ah si ay u isticmaalaan doorsoomayaasha in cutub oo cabbirka xaglaha - halbeegga ama darajo. Laakiin waqti isku mid ah, xisaabinta oo ka mid ah "gurguurta" joogto ah 2p, kaas oo, wada jir ah ula soo noqnoqoshada laga helay erayo badan xisaabta. Markaas waxay go'aansadeen inay soo bandhigto unit a modified cabirka inta jeer, oo wuxuu siiyey magaca "noqnoqoshada oscillation xilliile ah." Nuxurka cutubkan waa in ay inta jeer waxaa lagu go'aamiyaa tirada oscillations inta lagu guda jiro 2 seconds π *, i.e. 6,28 sec. inta jeer xilliile xisaabiyaa by caanaha ω = 2 * π * f. Lahaanshaha in inta jeer ee xilliile ninba ay unit of cabbirka - halbeegga per labaad.

nidaamka Oscillating weli beegyada uu qaar ka mid ah in sifaha iyada shakhsiyadda. Qaado our pendulum jir wanaagsan iyo wax yar ka weyn, waxa la yareeyo si ay gobolka ka ah geedi socodka gariirka - sax-tock, sax-tock. Si arrintan loo sameeyo hal mar waa ku filan si ay u riixaan iyo ... keligay baa hadhay. Waxa aynu arki doona? pendulum A oscillates dheer oo ku filan oo aan wax codsi oo dheeraad ah oo ka tirsan ciidanka, soo noqnoqoshada oscillation ay aysan waxba ka beddelin, iyo Ilodanimada inayan si tartiib tartiib ah hoos u, sababtoo ah ciidamada khilaaf ee qalabka dhabta ah. isbedbedelka noocan oo kale ah markii bilaabida ka dib markii cadaadis ka mid ah dhaqdhaqaaqa pendulum ah, ama hab kale oo wax gariirka waxaa ka go'an oo keliya by xuduudaha, loo yaqaan gaar ah. Haddii aynu ka fikirno in ciidamada waqti isku mid ah joojinta waa u siman yihiin in ay eber, oo waa mid aad u fudud - oo dhan in aannu gacmahayaga, pendulum noocan oo kale ah, waxa la yidhaahdaa waa xisaabeed ah, weligiis lagu baayici doonaa, oo muddo oscillation ah loo xisaabin karaa ka loo yaqaano, kaas oo uu horey u noqday classic ah, caanaha - C = 2 * * π l √ / g.

From falanqaynta waxaa suurtagal ah in la sameeyo gabagabo muhiim ah: inta jeer ee dabiiciga ah ee oscillation of pendulum la go'aamiyo kaliya by xuduudaha gudaha nidaamka - dhererka dunta iyo baaxadda xawaaraha ee cuf dhulka ee.
