Kugwedezeka kwa mzere: Zovuta za zinthu zomwe zimachitika m'dongosolo zimakhudzidwa ndi Lamulo la Hooke, ndipo gulu lamphamvu lomwe limapangidwa poyenda limakhala lofanana ndi gawo loyamba la velocity (nthawi yolumikizira).
ganizo
Dongosolo la mzere nthawi zambiri limakhala mtundu wa kugwedezeka kwa dongosolo lenileni. Kenako yankho la dongosololi mothandizidwa ndi X1 ndi X2 ndi Y1 + Y2.
Pamaziko a mfundo zapamwamba, zomwe zimachitika motsutsana zitha kupangidwira kuti zikhale zokhudzana ndi zigawo zingapo, kenako kuyankha kwathunthu kwa dongosololi kungapezekenso. mndandanda wamagulu a Harmonic ndi masinthidwe a haier, ndipo zotsatira za chinthu chilichonse champhamvu panjirayi chitha kusinthidwa mosiyana. Makina okhala ndi magawo osinthika amatha kufotokozedwa ndi kuyankha kwa chitsimikizo kapena yankho la pafupipafupi.
Kuyankha kwa kuwonetsa kumatanthauza kuyankha kwa makinawo kuti mutsimikizire, zomwe zimadziwika kuti ndi zomwe zimayankha m'dongosolo lazomwe zimayenderana ndi zigawo ziwirizi. ndi kusintha kwa zinayi.
kupatula
Kugwedezeka kwa mzere kumatha kugawidwa mu kugwedezeka kwa mzere umodzi-wa-ufulu ndi kugwedezeka kwa ma sing'anga ambiri.
. Kugwedezeka kogwirizana, kugwedezeka kwaulere, kugwedezeka kwa machesi ndi kukakamizidwa.
Gwiritsani ntchito kosavuta kwa gwiritsani ntchito:
Kugwedezeka kwamphamvu: Kugwedezeka komwe kumachitika matalikidwe omwe amakhala mosalekeza ndi kukhalapo kwa mikangano ndi kukana kwa sekondale kapena kugwiritsa ntchito mphamvu zina.
Kukakamizidwa kugwedezeka: kugwedezeka kwa dongosolo mosalekeza.
. Mwa dongosolo limatha kuyimitsidwa ngati njira yolumikizira mitundu yayikulu. kachitidwe Kugwira ntchito mobwerezabwereza pakati pa njira iliyonse ndikutulutsa, matrix opangidwa pafupipafupi. Purliced-Farlict Anfinity mawonekedwe a ufulu wa anthu osiyanasiyana ndi osiyana ndi omwe ali ndi ufulu.
Kugwedezeka kwa mzere umodzi wa ufulu
Kugwedeza kwa mzere momwe dongosolo la dongosolo lingadziwike ndi mgwirizano wosavuta komanso kofunikira kwambiri komwe malingaliro ambiri okhazikika amatha kugwedezeka. .
Varmoric kugwedezeka
Pakuchitapo kanthu kobwezeretsa mphamvu yoyambiranso, chinthucho chimatsitsa njira yake yofanana (mkuyu. 1) .x imayimira kusunthidwa ndikuyimira nthawi. Masamu a masamu a kugwedezeka awa ndi awa:
(1)Komwe kuli mtengo wothawirako x, womwe umatchedwa matalikidwe, ndikuyimira kukula kwa kugwedeza; amatchedwa gawo loyambirira la F = n / 2, kuchuluka kwa Oscillation Nthawi yomwe imatengera oscillate imodzi, ndipo imatchedwa nthawi yanthawiyo.plity a, pafupipafupi f (kapena gawo loyambirira n), gawo loyamba, lomwe limadziwika kuti kugwedezeka kwa zinthu zitatu.
CHITH. 1 yosavuta ya gwiritsani ntchito
Monga zikuwonetsera mkuyu. 2, chosavuta oskoric oscillator chimapangidwa ndi mizere yolumikizidwa ndi mzere wolumikizidwa.
Kodi kuuma kwa masika kumatanthauza kuti (1).
Koma Omega N imangotsimikizika ndi mapangidwe a kachitidwe akhamo m ndi k, popanda k, kudziyimira pawokha pazowonjezera, motero omega n amadziwikanso kuti pafupipafupi zachilengedwe.
CHITH. 2 digiri imodzi yokha ya ufulu
Kwa ostete yosavuta oslamonic, kuchuluka kwa mphamvu yake ya kinetic ndi mphamvu yake imakhazikika, ndiye kuti, mphamvu zonse zamakina zimagwiritsidwa ntchito.
Kugwedezeka kwamphamvu
Kugwedezeka komwe kumachitika chifukwa cha mikangano ndi kukana kwa sekondale kapena kugwedeza kwamitundu ina, ndipo kutsutsana kwapakati sikofanana, komwe kumatha kulembedwa ngati c Zovala zokutira.
(2)Komwe, m = c / 2m amatchedwa gawo lokhazikika, ndi.
(3)Ubale wapakati pa Omega N ndi Pip ikhoza kugawidwa m'njira zitatu izi:
N> (pankhani ya kutaya))
Mataliki ake amatsika ndi nthawi molingana ndi lamulo lomwe likuwonetsedwa mu equation, monga zikuwonekera pamzere wopezeka mu mkuyu. UTHENGA WABWINO, kugwedezeka kumeneku ndi ma apepiodic, koma pafupipafupi kwa nsonga yake ikhoza kufotokozedwa kuti:
Amatchedwa matalikidwe ochepetsa, nthawi ya kugwedezeka. Kuyesa kwa Delta ndi, kugwiritsa ntchito njira yomwe ili pamwambapa imawerengedwa c.
Pakadali pano, yankho la equation (2) lingalembedwe:
Pamodzi ndi kuwongolera koyambirira koyambirira, imatha kugawidwa m'milandu itatu yopanda pake monga ikuwonekera mu mkuyu. 4.
N <(Pankhani yokonza), yankho ku equation (2) likuwonetsedwa mu equation (3).
Kukakamizidwa kugwedezeka
Kugwedezeka kwa dongosolo mosalekeza.vibudition Kusanthula komwe kumapangitsa kuti nthawi ikhale yosangalatsa.Padic nthawi zonse kuyankha kwa dongosolo lililonse mwachidwiko kumafunikira.suntha zochita za harmic curce, njira yosiyanasiyana ya mayendedwe amodzi zitha kulembedwa:
Yankho ndi kuchuluka kwa magawo awiri. Gawo limodzi ndikuyankha kugwedezeka kwamphamvu, komwe kumawola mwachangu ndi nthawi. Kuyankha kwa gawo lina la kugwedezeka kungalembedwe:
CHITH. 3 zopindika zopindika
CHITH. 4 ma curves a zinthu zitatu zoyambirira ndi zovuta
Lembani mu
H / F0 = H (), ndiye kuti kuchuluka kwa kuyankha kwa matalikidwe, kuzindikiritsa matalikidwe aboma, kapena phindu la gawo la State komanso chidwi cha iwo komanso pafupipafupi kuwonetsedwa mkuyu. 5 ndi mkuyu. 6.
Monga tikuwonera kuchokera ku matalikidwe opindika (mkuyu. 5) otchedwa pafupipafupi dongosolo la madongosolo.in Kuthamanga kwachilengedwe, matalikidwe amakwera kwambiri. Izi zimatchedwa resonance. resonance, phindu la dongosololi limakulitsidwa, ndiye kuti, nthawi zonse kugwedezeka kopitilira muyeso. kugwedezeka.
CHITH. 5 matalikidwe pafupipafupi curve
Itha kuwoneka kuchokera ku gawo la magawo a gawo (Chithunzi 6), mosasamala kukula, mu omega zero gawo losiyana = pi / 2, mawonekedwewa amatha kugwiritsidwa ntchito poyeza resonance.
Kuphatikiza pa kukolola kosalekeza, nthawi zina kumatha kukumana ndi mitundu iwiri: imodzi ndi yovuta kwambiri.
Chida champhamvu pakuwunika kugwedezeka kwamphamvu ndi njira yoyankhira. ntchito nthawi zambiri imafotokozedwa ngati:
Komwe 0- ikuyimira mfundo pa T-Axis yomwe imayandikira zero kuchokera kumanzere; 0 kuphatikiza ndiye mfundo yomwe imapita kumanja.

Dongosolo limafanana ndi yankho la H (T) lomwe limapangidwa ndi chitsimikizo cha T = 0, chomwe chimatchedwa kuti chitsimikiziro cha chitsimikizo chisanachitike. Kuyankha kwa Dongosolo la Dongosolo la Dongosolo, titha kupeza yankho la madongosolo a X (T). 7) .Ti yankho la dongosolo ndi:
Kutengera mfundo yodziwika bwino, kuyankha kwathunthu kwa dongosololo kumayenderana ndi x (t) ndi:
Kuphatikizidwa uku kumatchedwa mboni zogwirizana kapena zophatikizika.
Kugwedezeka kwa mzere wambiri kwa madongosolo ambiri
Kugwedezeka kwa dongosolo la mzere ndi n n kofikwa za ufulu.
Chithunzi 8 chikuwonetsa ma stacks awiri osavuta omwe amalumikizidwa ndi masika ophatikizika. Ngakhale kuti ndi madontho awiri, magwiridwe awiri odziyimira pawokha amafunika kudziwa malo ake. Pali magawo awiri achilengedwe m'dongosolo lino:
Fraquency iliyonse imafanana ndi mtundu wa kugwedezeka. The harcillatic oscillators amagwira mawu ofanana ndi omega imodzi, x1 ndi yofanana ndi x2; mkati Kugwedeza kwakukulu kogwirizana ndi Omega Omega awiri, Omega Omega imodzi.in kugwedezeka kwakukulu, kuchuluka kwa misa iliyonse kumapangitsa mtundu wina, womwe umatchedwa mode kwenikweni kapena mtundu wachilengedwe. Kuzungulira kulikonse.
