Harmonic oscillations uye vibration muitiro purogiramu

Kuti tipindure mubvunzo chii zvinonzi harmonic oscillations, kunofanira kurangarirwa kuti izvi panyama mananara - mumwe rakajairika zvakasikwa. Zvichida, zvakaoma kutaridzwa kukura, izvo handizvo chipo harmonics. Vakawanda nzvimbo mumuviri pfungwa, izvo rinoongorora oscillatory pezvakaitwa ndivo zvemaziso, magetsi uye zvemagetsi, radar uye Akash, uye vamwe.

United pasina chaakasiya idzi kuitira kuti hunhu oscillatory pezvakaitwa vanowanzova zvakafanana, uye, naizvozvo, kuti kurondedzera navo pane vakawanda dzenhoroondo dzidziso. Parametric oscillatory kurongedza misiyano yakafanira chete wavo svikiro kuyerera uye zvimwewo zvinhu izvo zvingaita vibrational kufamba. Nyore Muenzaniso oscillatory inofamba, tinosangana muupenyu hwezuva nezuva, muri Somuenzaniso, oscillations pakati zvakavamba kuchinja wachi, kana zvemagetsi ano.

Nokufamba ari hunhu panowanikwa dzavo vakasununguka uye yakabatana. Free oscillations dzinonzi kuzvida, zvinonzi akasimbisa kuti vane sezvo dzinorwadza nechitarisiko nenyonganiso pamusoro svikiro, izvo zvinobva muviri kunofambira mberi zvakanyatsoenzana. Muenzaniso uri Bob, izvo yakaturikwa pedyo shinda, uye kuti tichawisira kubvunza vibration kwacho.

More nzvimbo inokosha panyama dzidziso anopiwa kuti kudzidza kutanga inozivikanwa harmonic vibrations. Kudzidza hunhu hwavo sezvo nguva uye anoumba yokungotaura hwaro pamusoro iyo kudzidza kunobva chaiwo zvinobatanidzwa oscillatory pezvakaitwa - kureva yakaitika yavo yakasiyana runyararo - Vanamakanika, magetsi, zvemakemikari transformations uye nezviito.

Kutsanangura wefizikisi ose harmonic oscillations mu huru parameters vaishandisa akadai nguva uye maitikiro.

Pachishandiswa kare akagadzira edu kutaura kuti pane rudzi vakawanda-chinangwa muenzaniso aibuda oscillatory urongwa, uye zvine musoro kusvika pakuguma nezvokuvapo kwezvimwe zvinhu zvose zvakasikwa kuti unhu nokufamba izvi. Somugumisiro, ambotaurwa parameters - nguva uye kakawanda cho ose oscillations, pasinei kunobva vezera, uye zvakatipoteredza kuti chiitiko chavo.

Kakawanda chinhu quantitative ukoshi inotaridza kangani kuti yakati rebei, muviri akaita urongwa kuchinja zvayo kunofambira mberi ehurumende uye vakadzokera kwaari. Somuenzaniso, unogona kuverenga kangani chete Bob oscillating pashure taingozvimanikidza kusvikira anomira.

Nguva iyi icharatidza nguva nguva uyo sinker dzikatsauka yepakutanga chinzvimbo uye anodzokera kumba imwe oscillation.

Nokuongorora harmonic oscillations, zvinofanira kunzwisiswa kuti nguva uye kakawanda chinangwa dzaibatanidzwa mukuru payakavakirwa, izvo pakupedzisira anosarudza kuti girafu pakati harmonic oscillations. Kuti uwane chinangwa kunzwisisa chii, zvinofanira kucherechedzwa kuti pane zvimwe zviratidzo parametric - amplitude, danho, kutenderera maitikiro. Kushandiswa kwavo kunoita kuti kushandisa kurondedzera oscillatory pezvakaitwa trigonometric mabasa. The inonyanya payakavakirwa yokuvakwa girafu riri sezvinotevera: s = A chivi (ωt + α). mutoo uyu anonziwo mukana wokuti vanhu vanga vane harmonic oscillations achibvumira kuvaka uye kuronga oscillation kwacho, izvo ayo nyore chimiro chinhu kwakajairika sinusoid. In muenzaniso pamusoro wevacheche, ivo coefficients α uye ω zvinoratidza chaizvo chii chinodiwa kuita kutendeuka kubva sinusoid kuratidza chaizvo oscillatory rikurumidze.

Kuti uwane kunzwisisa oscillatory mananara sezvingatarisirwa yakaoma uye kwakajeka tsananguro. kuomesa Izvi imhaka pokudzora Pane zvinhu zviviri:

- hunhu acho, kureva kuti chii anoongorora nokufamba - zvemaziso, remagetsi, kana zvimwe cyclic;

- svikiro mukati iyo kunotangira uye rakatangwa oscillatory mananara - mhepo, mvura kana zvimwe.

Zvinhu izvi yekudyidzana dzinochinja parameters zvose chero oscillating kwacho.
