Oscillation free

geeddi socodka Oscillatory - mid ka mid ah ifafaale ugu badan ee dabiiciga ah. Waxay daraasad ku lug laamaha kala duwan ee aqoonta, gaar ahaan physics. Si aad ka jawaabto su'aasha ah waxa loo yaqaan oscillations free, waxaa in la xuso in this category waa tixraac daraasadda of kala duwan oo dhan ifafaale oscillatory ka dhaca dabeecadda.

Waxaa jira noocyada soo socda, sida uu tilmaamay sababaha soo socda.

dabeecadda Physical kala saaro vibrations farsamo, electromagnetic iyo isku qasan, isku sifooyinka hore u soo sheegnay.

By habka qulquli deeganada dhaadheer vibrations:

- qasbay, in uu yahay, kuwa loo yeedhay, oo sarkhaansan yihiin noocyada kala duwan ee bay'ada rabshooyin dibadda, taas oo ay dhici iman. Isla mar ahaantaana waa inay u hoggaansamaan shuruudaha periodicity ee rabshooyin kuwan;

- oscillations free, loo yaqaan xitaa u gaar ah, kuwaas oo bilaabay gudaha sifooyinka nidaamka iyo taas oo muujin qabanaya attenuation marka tallaabada ciidamada gudaha joogsanayo ama hoos,

- oscillations - sida kuwaas oo lagu gartaa joogitaanka awoodda nidaam (tamarta), bixinta oscillations dhaliyay. Home badan oscillations free kala duwan ka oscillations, ku tiirsanaanta Ilodanimada inayan aan la hadlayey xoog hore ee wadnaha bilaabin, iyo sifooyinka nidaamka jirka;

- dhimaya - waxaa gariirka oo dhab ahaan ka yar hawsha nidaamka oscillating ka dhawrsada dhimaya kasta oo saadaalineysa guryaha daarmayaay'e muuqan;

- isbedbedelka random yihiin kuwa u dhaqmaan on arrimaha geedi socodka oscillatory waa random, ma parametric ee dabiiciga ah.

Gebogebadii astaamahaan, waxaa lagu soo gabagabeeyey karaa in, in isbedbedelka ay ugu foomka guud - this lagu celceliyo si joogto ah la beddelo qaar ka mid ah nidaamka si xushmad leh in ay gobolka hoganaya ay. Meelaha ugu badan ee daliilka u ah hababka oscillatory ee dabiiciga ah waa farsamo ifafaale, kiimikada, la ruxruxo iyo korontada, xiddigaha, iyo kuwa kale electromagnetic. Muuqaalka caadi ah oo dhan, iyada oo aan marka laga reebo, hababka gariirka, waa in ay si toos ah u xiran guurka tamarta - Isbadal ka mid ah qaab tamar kale.

Sida hore u soo sheegnay, bar bilow ka ah baaritaanka nooca geedi socodka oscillatory ah, waa waxbarasho ee noocyada sida oscillations sida free. Ay astaamaha asaasiga ah waa kuwan soo socda:

- the Ilodanimada (A) - qiimaha ugu badan ee kala duwanaansho ah ee nidaamka gobolka hoganaya ay (tilmaame ugu badan loo isticmaalo ee qiimaha celcelis ahaan);

- muddo (T) - muddo waqti go'an inta lagu guda jiro kaas oo ay macquul tahay in ay saxaan dalalka nidaamka celceliyay,

- inta jeer ee dabiiciga ah (f) - tirada gariirka, taas oo ka dhigaysa nidaamka cutubkan ah waqti cayiman. Halbeegga Tan waxaa lagu qiyaasay in Hertz (Hz).

Xiriirka ka argument kuwaas oo ka tarjumaya formula ah in lagu tilmaamay gariirka xorta ah sida ugub ah. Waayo, nidaamka vibrational kala duwan oo xuduudaheedu ee caanaha waxaa ka mid ah isu-gaynta kala duwan, taas oo ku xidhan waxa si gaar ah nidaamka hoos tixgelin.

Tusaale ahaan, in muddada ugu fudud resonant circuit iyo inta jeer ee la xiriira by: f = 1 / T, Xaggeeda, waxaa iska cad in muddada iyo inta jeer waa qiimaha-bedelka.

Haddii aan ka fiirsan oscillations free ka dhaca nidaamka noocan oo kale ah, kaas oo fadhiya jiidasho baxaan, taas oo uu leeyahay a barti gaar ah (k), waa in racfaan sharciga labaad Newton ee. Marka la eego ay caanaha ka muuqato hantida vibrational nidaamka uu noqdo: F = -kx. Tani waxay soo jeedinaysaa in haddii aan iska indha qiyamka ciidamada khilaaf iyo miisaanka qaaday sida qiimaha joogto ah, nidaamka noocan oo kale ah had iyo jeer lagu baayici doonaa isla muddadaas, xitaa marka la amplitudes kala duwan iyo shuruudaha bilowga ah ee ay dhacdo.
