Oscillation free

Iinkqubo Oscillatory - enye nesenzeko ixhaphakileyo indalo. isifundo owawubhekisela amasebe ezahlukeneyo ulwazi, ingakumbi physics. Ukuze uphendule lo mbuzo oko kuthiwa oscillations ezamahala ke, kufanele kuphawulwe ukuba olu didi reference ekufundeni yonke ezahlukeneyo iziganeko oscillatory ezenzeka kwindalo.

Kukho ezi ndidi zilandelayo, zihlelwe ngokwezi zizathu zilandelayo.

uhlobo Physical bahlule intlokoma mechanical, umoya kunye engumxube, edibanisa iimpawu senditshilo.

Ngendlela kungena bume ayikhuphi intlokoma:

- ngenkani, oko kukuthi, abo babiziweyo uze phantsi kweempembelelo iintlobo ezahlukeneyo iimeko zangaphandle yokuphazamiseka kuzo. Ngelo xesha kufuneka athobele imiqathango periodicity ezi yokuphazamiseka;

- oscillations free, ebizwa nokuba zakho, ezo iqaliswe zangaphakathi iimpawu inkqubo kwaye babonise ziyabophelela eziphango xa isenzo imikhosi lwangaphakathi liyayeka okanye sehlise;

- oscillations - ololo luphawulwa bubukho inkqubo umthamo (amandla angekasetyenziswa), ukunika oscillations amanqaku. Ekhaya ngaphezu oscillations ezamahala sahlukile oscillations, lo ukuxhomekeka awo lo uthetha kwi amandla lokuqala ukubetha kwanokuqalisa, kwaye iimpawu kwenkqubo ngokomzimba;

- parameter - it Iintshukumo ezo eyenziwe phantsi umsebenzi kwenkqubo abazi jinga nawuphi parameter oluvelayo iipropati ukubonakaliswa kuma;

- okunzulu random zezo izinto phezu imiba kwinkqubo oscillatory ezi random, hayi parametric kwindalo.

UPawulos ezi mpawu, kunokwenziwa isigqibo ukuba, yayo ezininzi ifomu jikelele ukuhla - oku iyaphindwa rhoqo ukutshintsha ezinye nkqubo ngokuphathelele kule ngxuba kuvuselele. Le ndawo oluqhelekileyo ekubonakalisweni yeenkqubo oscillatory indalo ezi mechanical nesenzeko, imichiza, yomtshangatshangiso zombane, ngeenkwenkwezi, nezinye kagesi. Eyona oqhelekileyo zonke, ngaphandle kokukhetha, iindlela ukungcangcazela, kukuba ezinxulumene ngqo amandla lenguqu - inguqu omnye uhlobo lwamandla kwenye.

Njengoko sele kukhankanyiwe, indawo yokuqala yokuphanda uhlobo iinkqubo oscillatory, kufundwa kweentlobo ezifana oscillations abakhululekileyo. iimpawu zazo zokuqala zezi zilandelayo:

- le awo (A) - xabiso liphezulu ukutshintshwa kwenkqubo kwimeko yayo lizama (the ezininzi eziqhele ukusetyenziswa olubonisa ixabiso avareji);

- period (T) - ixesha elithile ngexesha apho kunokwenzeka ukulungisa inkqubo uphindaphindo ithi;

- njalo zendalo (f) - inani intlokoma, nto leyo eyenza le nkqubo icandelo elithile. Le eyesibini iparameter ngee elilodwa (Hz).

Ubudlelwane ezi parameters zibonisa indlela oluphawula lokungcangcazela simahla nje senzeko. Kwiinkqubo ezahlukeneyo vibrational iparameters kule formula zibandakanyiwe nendibaniselwano ezahlukeneyo, kuxhomekeke kwinkqubo ethile phantsi ingqalelo.

Ngokomzekelo, kwisithuba yesekethe elula resonant kunye rhoqo zihlobene ngu: f = 1 / T, kulowo kuyabonakala ukuba ixesha namatyeli zizinto amaxabiso nguqu.

Xa siqwalasela oscillations ezamahala ukuba kwenzeka inkqubo enjalo, nto leyo Iqinisekile statically ukuntshula, nto leyo iba okubuyela kwimo ethile (k), apho kufuneka isibheno umthetho wesibini Newton. Ngenxa ifomula yayo ebonisa iimpawu vibrational yale nkqubo iba: F = -kx. Oku kubonisa ukuba xa ngoyaba amaxabiso bezimpi ungquzulwano ubunzima kuthathwe ixabiso rhoqo, inkqubo enjalo kusoloko oscillate kunye xesha, nkqu ngezantya ezahlukeneyo kunye neemeko zokuqala kwazo.
