Oscillation damped

izinqubo Oscillatory azungeze umuntu yonke indawo. Lesi simo esiyingqayizivele sibangelwa kungenxa yokuthi, okokuqala, ngokwemvelo, zikhona izindawo eziningi (ephathelene nomzimba namakhemikhali awo, organic, njll), lapho kunyakaza zenzeka, kuhlanganise oscillations damped. Okwesibili, ekubeni ngokoqobo elisizungezile kukhona okunhlobonhlobo oscillating izinhlelo khona kwalo ixhunyaniswe izinqubo oscillatory. Lezi zinqubo asizombelezileko, bona elichaza ukugeleza samanje izintambo, izenzakalo ukukhanya, igagasi esiphelweni, nokuningi. Ekugcineni, umuntu ngokwakhe, noma esikhundleni emzimbeni womuntu, kuyinto uhlelo oscillating, okuphila olunikezwa izinhlobo ezahlukene iyehla iyenyuka - ukushaya kwenhliziyo, ukuphefumula, kwegazi, esitho ukunyakaza.

Ngakho-ke, lebayifundzako wesayensi ezihlukahlukene, kuhlanganise imikhakha eyahlukene. Indlela elula futhi wakuqala zalolu cwaningo zingokulandelayo kunyakaza khulula. Basuke izimpawu ukukhathala amandla vibrational ka-pulse, ngakho ekugcineni wayeka futhi ngoba ekushintshashintsheni ezinjalo zinqunywa nomqondo oscillations damped.

Esikhathini izinhlelo oscillatory elibanzi kwenzeka amandla ukulahleka inqubo (kumasistimu mechanical - ngenxa ukungezwani kagesi - ngenxa yokubakhona ukumelana kagesi). Yingakho oscillations ezinjalo damped ayikwazi labizwa ngokuthi harmonic. Njengoba sazi lokhu isitatimende sokuqala, singakwazi ziveza izibalo etholakala, isibonelo, Mechanics we damped oscillations ifomula wezwakalisa njengoba: F = - RV = -R dx / DT. Kulesi ifomula, r ukumelana Coefficient, value njalo. Ngokusho ifomula, singaphetha ngokuthi ukubaluleka the velocity (V) uhlelo ngokulingana nenani ukumelana. Kodwa khona isibonakaliso "-" kusho ukuthi Vector amandla (F) nesivinini kukhona bemvelo ahlukahlukene.

Ukusebenzisa equation yesibili Newton uMthetho, futhi kucatshangelwa ithonya ukumelana amabutho, ezothando ephawula damped oscillation ukunyakaza nqubo ithatha ifomu elilandelayo: ebukhoneni ibutho ukumelana ine uhlobo: d ^ 2x / dt2 + 2β DT / DT + ω2 x = 0. Kulesi ifomula β - Damping Coefficient, okhombisa izinga kwalesi isigaba sayo yonke le nqubo oscillatory.

Izimo zethu zihluke kakhulu kwesibalo efanayo ingatholakala i wesifunda kagesi, ikhumbula Damping futhi wanezela kuze kufike ohlangothini lwesobunxele yokwehla kwamandla yonkana UR Resistor. Kuphela kuleli cala, ezothando umehluko alubhaliwe ngokokuqala offset (t), kanye lokukhokhisa q capacitor (t); ngomshikisho Coefficient r esikhundleni kagesi ukumelana wesifunda R; 2 lapho β = R / L, lapho K - Ukumelana wesifunda, L - ubude iketanga.

Uma ngesisekelo lezi amafomula ukwakha emagrafu ohambelana, ungabona ukuthi igrafu oscillations damped kuyinto ihluzo ezithi azifane oscillations harmonic, kodwa amplitude oscillations kancane kancane kunciphisa exponentially.

Sikhishwe yokuthi oscillations engenziwa nge izinhlelo ezihlukahlukene oscillatory futhi kwenzeka ezihlukahlukene izindawo, kubalulekile ukuba liyasho ukuthi, onjani uhlelo sicabanga esimweni ngasinye. Kusukela kulesi simo ungaxhomeki kuphela izici olukhethekile izinqubo oscillatory, kodwa kukhona nomphumela ohlukile - ubunjalo oscillations kunqunywa uhlelo uqobo kanye ngezigaba zawo endaweni. Siye, kulesi simo, njengelinye lamazwe lapho izakhiwo kohlelo zihlala zinjalo phakathi nesifundo oscillatory inqubo. Ngokwesibonelo, sicabanga ukuthi inqubo ayishintshi kuyaqina entwasahlobo, amandla adonsela phansi ayisukumele umthwalo, futhi izinhlelo kagesi akukashintshi kuncike ukumelana ijubane noma ukusheshisa lamanani oscillating. izinhlelo ezinjalo oscillatory zibizwa ngokuthi komugqa.
