Oscillations Harmonic nokucubungula vibration isheduli

Ukuze siphendule umbuzo lokho okubizwa ngokuthi ama oscillations harmonic, kufanele kukhunjulwe ukuthi lezi zenzakalo ngokomzimba - omunye okuvame kakhulu nemvelo. Mhlawumbe, kunzima libalule, okuyinto akavumanga Harmonics samanje. Ezindaweni ezivame kakhulu ithiyori ngokomzimba, okuyinto ihlola izinqubo oscillatory kukhona mechanical, electrical kanye electronics, radar kanye sonar, nabanye.

United abantu ngothi lwabo, lezi zindawo ukuze ubunjalo izinqubo oscillatory ngokuvamile okufanayo, futhi ngenxa yalokho, ukuchaza kubo kukhona theory jikelele we-classic. oscillatory parametric icubungula umehluko luye kuJehova kuphela. ukugeleza yabo aphakathi nendawo kanye izici zangaphandle ezingase zithinte ukunyakaza vibrational. Isibonelo elula motion oscillatory, esingase sibhekane nabo ekuphileni kwansuku zonke, yilezi, isibonelo, oscillations iwashi okuthiwa i-pendulum, noma kagesi.

Ekushintshashintsheni ubunjalo nesenzakalo yabo amahhala nobunye. oscillations Mahhala abizwa ngokuthi yokuzithiba, it is wagcizelela ukuthi banayo njengoba umthombo wabo yokuphazamiseka sangaphandle medium, okuyinto ususelwe umzimba wenyama yakhoibrium static. Isibonelo salokhu bob, okuyinto okwesikhashana by intambo, nokuthi sizakulahla ukubuza inqubo vibration.

Okuningi indawo ebalulekile theory ngokomzimba kunikezwa ekutadisheni into eyaziwa ngokuthi kunyakaza harmonic. Ucwaningo ngesimo sabo njengobe isikhathi, lwakha isisekelo theory lapho isifundo kusekelwe izici esikhethekile oscillatory izinqubo - okungukuthi, nesenzakalo yabo ezindaweni ezahlukene - Mechanics, ugesi, amakhemikhali kugucuka nendlela ezisabela ngayo.

Ukuchaza yemvelo ka oscillations harmonic e nemingcele main esetshenziswa ezifana nongqi imvamisa.

Ngokusekelwe ngaphambilini owasungulwa ukugomela yethu ukuthi kukhona uhlobo imodeli jikelele-injongo ukugeleza izinqubo oscillatory, futhi singaphetha ngokunengqondo bafinyelela esiphethweni mayelana nokuba khona kwamakamu amagugu ethile jikelele agcwele la iyehla iyenyuka. Ngenxa yalokho, nemingcele okukhulunywa - inkathi kanye nobuningi nobuntu zonke izinhlobo oscillations, kungakhathalekile umthombo sizukulwane, imvelo nesenzakalo yabo.

Imvamisa kuba value ambalwa kukhombisa isibalo izikhathi ngobude esithile, ngokomzimba umzimba uzibophezele inqubo ekushintsheni esimweni saso static wabuyisela kuye. Ngokwesibonelo, ungakwazi ukubala inani lezikhathi okufanayo bob oscillating emva thina kwaphoqa lize lithi khimilili.

Isikhathi yale nqubo sizobonisa isikhathi lapho Sinker kuphambuka isikhundla sokuqala bese ubuyela emzini womunye oscillation.

Ngokuhlola oscillations harmonic, kufanele kuqondwe ukuthi isikhathi kanye nokuvama injongo exhumene by ifomula jikelele okwagcina inquma igrafu oscillations harmonic. Ukuze ngokwengeziwe ukuqonda ukuthi kuyini, kufanele kuphawulwe ukuthi kukhona nezinye izici parametric - amplitude, isigaba, umjikelezo imvamisa. Ukusebenzisa kwabo ikuvumela ukuthi usebenzise ukuchaza izinqubo oscillatory imisebenzi Trigonometric. Ifomula ezivamile ukwakhiwa igrafu simiswe ngalendlela lelandzelako: s = A isono (ωt + α). Lokhu ifomula obizwa nangokuthi ezothando ka oscillations harmonic ivumela ukwakha futhi ukuhlela inqubo oscillation, okuyinto njengoba injalo elula kuyinto sinusoid ezivamile. Kusibonelo esingaphezulu ifomula, le okuza α futhi ω ukukhombisa kahle ukuthi kuyadingeka ukwenza ukuguqulwa kusuka sinusoid ukubonisa oscillatory inqubo ethize.

Ukuze uthole olunye eziyinkimbinkimbi oscillatory imihlola incazelo ngokwemvelo kuyinkimbinkimbi futhi ingcaca. Lokhu inkinga kungenxa yethonya lezingane izici ezimbili ezibalulekile:

- uhlobo inqubo, okungukuthi, ngalokho-ke uhlola iyehla iyenyuka - mechanical, kagesi, noma ezinye eyindilinga;

- naphakathi ngaphakathi okuyinto yilabo abake futhi iqaliswe imihlola oscillatory - umoya, amanzi noma ngenye indlela.

Lezi zici kakhulu ukuthonya zonke kwemigomo iyiphi inqubo oscillating.
