Waxbarashada vibrations farsamo

na ku nool dunida ee jirka waxaa ka buuxa dhaqdhaqaaqa. Ku dhowaad aan macquul aheyn in la helo ugu yaraan hal jidhka, kaas oo loo karin sida iyagoo ku nastaan. siman Weeraryahanka rectilinear sokow mooshin, mooshinka ee dhabbihii adag, dardargelinta dhaqdhaqaaq iyo kuwo kale, waxaannu u arki karaan gacanta ugu horeysay, ama ku xanuunsado saameynta dhaq noqnoqonaysa oo alaab ah qalab.

Nin ayaa ogaaday qaababka kala iyo sifooyinka of dhaqdhaqaaqa oscillatory, iyo xataa bartay in ay isticmaalaan vibrations farsamo ujeedooyin iyaga u gaar ah. All hababka waqti xilliyo gaar noqnoqda laga yaabaa in lagu soo sheegnay gariirka. vibrations farsamo waa uun qayb ka mid ah ifafaale kala duwan ee dunida, ka dhacaya shiidaa sharciyada isla. On tusaale muuqaal ah dhaqdhaqaaqa noqnoqda farsamo ka dhigi kartaa xeerarka aasaasiga ah iyo si loo ogaado sharciyada u biilaabay geedi socodka oscillatory electromagnetic, korontada iyo kuwa kale.

dabiiciga ah ee ay oscillations wareegsan farsamo waa in beddelidda ee tamarta galay tamarta ogeed. In lagu qeexo tusaale sida diinta tamarta qaadataa meel by vibrations farsamo noqon kartaa, ka fiirsaneysa inay kubada, ganaax on il. In jiifnay ciidanka of cuf waa la dheeli by ciidamada laastikada ah ee guga. Laakiin waxaa lagama maarmaan ah in la keeno nidaamka ka mid ah ciidamada dheelitirka, sidaas keenaysay dhaqdhaqaaqa kooxda ka mid ah, barta ay ka kortay, sida tamarta bilaabi doonaan in ay isbadal galay tamarta ogeed. Iyo in, markeeda, laga bilaabo waqtiga la marayo booska kubad eber bilaabaa inuu la beddelay iman kara. Marxaladani waxay qaadataa meel inta shuruudaha jiritaanka nidaamka ku dhow inay hufan.

Xisaab ahaan loo arkaa isbedbedelka fiican ku dhacda shaqada Culumida ama cosine. Hababka noocaas ahi waxaa la yiraahdaa oscillations harmonic. tusaale ahaan ku haboon ee mooshinka farsamo waa oscillations harmonic of pendulum ee gabi ahaanba vacuum, marka ay jirto saamayn lahayn ciidamada khilaaf. Laakiin waa kiiska gabi ahaanba meella, si loo gaaro taas oo farsamo ahaan waa mid aad u adag.

vibrations farsamo, in kasta oo ay duration, ha dhawaado ama ha joojiyo, iyo nidaamka degan meel ka mid ah hoganaya qaraabo. Tani waxay dhacdaa sabab u ah qashinka tamarta in ay ka gudbaan iska caabin ah hawada, khilaaf iyo arrimo kale, ciday ku keeni doontaa in ka bedelaan xisaabinta ee guurka ka fiican in ay xaaladaha dhabta ah taas oo ay jirto nidaamka su'aal.

Eegan u dhaw in ay baadhitaan qoto dheer iyo falanqayn, waxaan u baahan nahay in xisaab ahaan sharaxo vibrations farsamo. Formula geedi socodka waxa ka mid ah tiro sida Ilodanimada (A), inta jeer oscillation ah (w), wajiga hore (a). function A ee barakaca (X) oo ay kasoo horjeeddo waqti (t) ayaa qaab foom classical

x = Acos (WT + a).

Waxa kale oo xusid mudan qiimaha sifeeyay ku vibrations farsamo, isagoo magac - muddada (T), taas oo ah waxa lagu qeexaa sida xisaab ahaan

T = 2π / w.

vibrations farsamo, marka lagu daro aragti ah ee description non-farsamo oo ka mid ah geedi socodka of libiqsanayn dabiiciga ah, waxaan ku mashquulsan yihiin qaar ka mid ah guryaha in, marka si habboon loo isticmaalo, ku siin karaan lacagta qaar ka mid ah, oo haddii la dayaco, - hogaanka dhibaato weyn.

fiiro gaar ah in la bixiyo, in ay ifafaale ah ee u kaca fiiqan ee Ilodanimada inayan reer oscillations qasbay soo socda marka inta jeer ee saameynta ciidanka wadidda in inta jeer ee ay oscillations ee jirka. Waxaa lagu magacaabaa resonance. Si ballaaran loo isticmaalo qalabka korontada, hababka farsamoyaqaanka, ifafaale resonance waxa badi muujiyey nooca burbur, waa in la tixgeliyaa marka la abuurayo kala duwan ee dhismayaasha farsamo iyo nidaamka.

muujinta A dheeraad ah vibrations farsamo waa gariirka ah. Its muuqaalka yeelan kartaa ma aha oo kaliya raaxo gaar ah, laakiin sidoo kale in ay keenaan si ay u dhacdo ee resonance. Laakiin ka Saameynta xun marka laga reebo, vibrations maxaliga ah leh oo u hooseeya astaamaha wanaagsan guud ahaan saamayn ku yeelan karaan on jidhka bini'aadamka, hagaajinta gobolka functional ah ee nidaamka dhexe ee habdhiska, iyo xitaa loo dardar-ka bogsashada nabrihii , iwm

embodiments dheeraad ah muujinta oscillations farsamo kala saari karaa ultrasound arrin ku dhawaaqa. guryaha waxtar leh farsamo oo ka mid ah hirarka iyo daliilka kale oo ka mid ah oscillations farsamo hubkaas ayaa loo isticmaalaa in beeraha kala duwan ee dhaqdhaqaaqa aadanaha.
