Cyclic maitikiro - chii uye sei?

Munyika yakatipoteredza, pane zviitiko zvakawanda uye pezvakaitwa, zviripo, uye makuru, asingaoneki, kwete nekuti havapo, asi nekuti isu havambokwanisi cherechedzai navo. Vanogara varipo uye ndiwo chete zvisingaoneki uye kuvapo chaizvoizvo zvinhu, pasina izvo upenyu hwedu uye zvakaoma kufungidzira. Mumwe Somuenzaniso, zvinozivikanwa kuti kusiyana-siyana akadai: zvavo nemashoko - yakatsauka kubva zvakanyatsoenzana wehurumende. Eya, muromo Ostankino shongwe waishandiswa zvavo 5 vakasuwa uye zvino chii? Uye anoomesa? Hapana sezvizvi unotanga kuuya shure, vapedzisire zvakanyatsoenzana uye vachaitwa vakatsauka mu negwara, nezvimwewo nokusingaperi, chero bedzi ruchavapo. Ndiudze, vazhinji vakamboona zvikuru zvakakomba nokufamba izvi zvakadai hurongwa akakura? Munhu wose anoziva zvinyamusi, pano, ipapo, pano, ipapo, masikati nousiku, chando uye chirimo, asi zvimwe ... kwete zvikuru. Zvikonzero oscillatory muitiro - ndeimwewo nyaya, asi ayo kuvapo ndiyo - ane vasingasiyani chokufunga zvose.

Yemakomo kumativi ose; zvivakwa, zvakavamba kuchinja wachi, mashizha pamiti, gitare hungiso, pemvura zhinji, makumbo forogo ... Pakati nokufamba kusiyanisa runobva kuti havana kunyatsoteerera repeatability, uye cyclic, uyo kwechinguva nguva T oscillating muviri rinopfuura wenguva yakatarwa yayo anoshandura, uye ipapo kutenderera ari zvakangofanana, kazhinji kutaura, nokusingaperi. Kazhinji, kuchinja izvi achireva sequential Ongororo pakati spatial Coordonatele, sezvo zvinogona kuonekwa oscillations pakati zvakavamba kuchinja, kana chete shongwe.

Kuwanda oscillations por chikwata nguva anonzi kakawanda F = 1 / T. Frequency chipimo chikwata - Hz = 1 / s. Zviri pachena kuti cyclic kakawanda ndiwo parameter mumwechete zita kuzengurira chero mhando. Zvisinei, muna tsika, izvozvo akabvuma pfungwa iyi, vamwe kuwedzera dzinorondedzera zvikurukuru rotational zvakaita nokufamba. It saka zvakaitika unyanzvi kuti rotational kufamba ndiyo hwaro vakawanda michina, maturusi namano. Nokuti mumwe kutenderera oscillation mumwe dzokai, uye ipapo yamunenge kushandisa chisina kutsetseka misha parameters. Nokudaro, rotational kufamba akayera chisina kutsetseka dzakabatana, i.e. mumwe chimurenga akaenzana 2π radians, uye cyclic kakawanda ῳ = 2π / T. Kubva aya munenge iri pachena kukurukurirana Frequency F: ῳ = 2πF. Izvi zvinoita kuti tikwanise kutaura kuti cyclic kakawanda - nhamba oscillations (azere majana) pamusoro 2π seconds.

Zvinoita sokuti, hazvisi pahuma, saka ... Kwete chaizvoizvo. 2π multipliers uye 2πF rakashandiswa zhinji zvemagetsi equations, akarongeka uye yokungotaura wefizikisi zviri zvikamu umo oscillatory pezvakaitwa vari kudzidza kushandisa pfungwa cyclic maitikiro. The yemaitiro of resonance kakawanda Somuenzaniso, ipfupi nezvinhu zviviri. Kana kushandiswa dzemaitirwe chikwata "vol. / Sec" chisina kutsetseka, cyclic maitikiro ῳ dziwande rinobatana kukosha kakawanda F.

Nokufamba, sezvo chaizvoizvo uye chimiro kuvapo nyaya, uye zimukadzimu wayo chaiye - vanotongwa yedu emuviri zvikuru muupenyu hwevanhu. Zivo mitemo vibrations zvinobvira kusika akura zvemagetsi, zvemagetsi engineering, vakawanda mazuva ano michina. Zvinosuruvarisa kuti nokufamba havasi kuuya kunobatsirawo, dzimwe nguva vanouya kusuwa uye kuparadzwa. Unaccounted oscillations kukonzera tsaona zhinji, zvichikonzera kukurumidza kuchembera zviri zvinhu, uye chisina kutsetseka kakawanda pamusoro resonance oscillations pakati mabhiriji, madhamu, muchina zvikamu kunokonzera rokusamhanyira kukundikana kwavo. Kudzidza oscillatory urongwa, kufanotaura maitiro dzinongoitika uye michina zvivako kuitira kudzivirira kuparadza avo kana anongoerekana kuti uchishandisa wehurumende - huru basa vazhinji injiniya zvikumbiro, uye vakaongorora maindasitiri zvivako uye vibration mashandiro - a zvaida chinhu nazvo.
