Mahala oscillation

Oscillatory dithulaganyo - e mong oa liketsahalo atileng ka ho fetisisa linthong tsa tlhaho. thuto ea bona ho akarelletsa le makala a sa tšoaneng a tsebo, haholo-holo ea fisiks. E le ho araba potso ea hore na li bitsoa oscillations free, re lokela ho hlokomela hore sehlopha sena se bolela ho ithuta mefuta e fapaneng oohle oa liketsahalo oscillatory tse etsahalang ka tlhaho.

Ho na le mefuta e latelang, classified latela mabaka ana a latelang.

mofuta Physical khetholla loebehlana phetha molao, motlakase le ho e tsoakiloeng, kopantseng likarolo ho se ho boletsoe.

Ke tsela phalla ka libakeng emit loebehlana:

- qobelloang, ke hore, ba hore ba bitsoa 'me ba fihle ka tlas'a tšusumetso ea mefuta e sa tšoaneng ea libakeng Link meferefere eo ba etsahala. Ka nako e tšoanang e lokela ho dumellana le dipehelo tsa periodicity ea meferefere tsena;

- mahala oscillations, e bitsoang esita le mong, tse qadile ke hare litšobotsi tsa tsamaiso le eo Bontša tlamang attenuation ha bohato ba mabotho a ka hare a kgaotsa kapa decreases;

- oscillations - jwalo tse tšoauoa ka ho ba teng ha tsamaiso bokgoni (eneji, le bokgoni ba), ho fana ka bona maduo oscillations. Home feta oscillations mahala fapana oscillations, e leng molumo itshetlehileng e sa bua ka matla ka lekhetlo la pele ba pulse length ho qapa, 'me litšobotsi tsa tsamaiso ea' meleng;

- paramethara - e ho loebehlana ha tse hlahisoang tlas'a elang hloko mosebetsi oscillating tsamaiso ea paramethara efe kapa efe projecting thepa ponahalo ambient;

- liphetoho ka tšohanyetso ba elang eo sebetsa ka lintlha oscillatory thulaganyou e ke tšohanyetso, ha parametric ka tlhaho.

Ha a akaretsa litšobotsi tse tsena, e ka etsa qeto ea hore, ka liphetoho tsa lona ho fetisisa akaretsang foromo - ena e phetoa ka dikgao tsa kamehla fetola ba bang ba tsamaiso ea mabapi le boemo lona equilibrium. The libakeng tse atileng ka ho fetisisa ea liponahatso tsa dithulaganyo oscillatory tsa tlhaho ke ho phetha molao feela liketsahalo, lik'hemik'hale, tsokoang le motlakase, bolepi ba linaleli, 'me tse ling tsa motlakase. A tsobotsi e tloaelehileng ea tsohle, ntle ho mokgelo, thothometsa mekhoa, e le hore ba ba ka ho toba e amanang le ho phetoho ea eneji, le - oa ho fetola e mong mofuta o matla ka e 'ngoe.

Joalokaha ho se ho boletsoe, ho qala ka ho batlisisa hore sebopeho sa dithulaganyo oscillatory, ke ho ithuta mefuta e kang bolokolohi oscillations. litšobotsi tse tsa bona tsa mantlha tse latelang:

- the molumo (A) - boleng palo e kahodimodimo ea phetoho ea tsamaiso ea ho tloha boemong ba lona equilibrium (ka ho fetisisa e atisa ho sebelisoa pontshi tsa boleng karolelano);

- nako (T) - e itseng nako eo ka eona ho ke ke ho bonolo ho e lokisa ho pheta-pheta tsamaiso e khopo e re;

- tsa tlhaho maqhubu (f) - palo ea loebehlana, e leng se etsang tsamaiso bakeng sa itseng unit trust nako. paramethara ena e lekanngoa ka Hertz (Hz).

Kamano ea entsprechen tsena bonahatsa moralo oo ba tsebahala ka mahala thothometsa ka ketsahalo e. Bakeng sa tsamaiso ea tse fapa-fapaneng vibrational entsprechen ka moralo ona li kenyelelitsoe tlhakantsuke tse fapa-fapaneng, ho itšetlehile ka oona tsamaisong seo ho khetheha ka eona.

Ka mohlala, ka nako e bonolo resonant potoloho le maqhubu a li amana ka ho: o f = 1 / T, therefrom ho hlakile hore nako le maqhubu a ke melao ea boitšoaro e bapileng.

Ha re nahana ka oscillations lokolohile hore etsahala joalo tsamaiso, e tsitsitseng statically hlaha, e leng o na le e itseng elasticity (K), ho na le lokela ho etsa boipiletso ho molao bobeli Newton o. Fanoeng moralo lona hore bonahatsa thepa vibrational ba tsamaiso ena e fetoha: F = -kx. Sena se bontša hore haeba re hlokomoloha melao ea boitšoaro ba mabotho ea khohlano le boima nkiloeng ka boleng kamehla, tsamaiso ea joalo tla lula oscillate le nako e tšoanang, esita le ka amplitudes fapaneng le maemo a ea pele ea ketsahalo e sa bona.
