Pulu ka oscillation

Oscillatory keʻano o ka hanaʻana a puni ke kanaka mai'ō a'ō. O kŰia aie i ka mea e, mua, ma ke ano maoli, ua nui na hana kūpono (physical, Nine Inch, ke aloha, etc.), ma i kuekueni ana, a me ka pulu ka oscillations. Ka lua, ma ka ike maopopo a puni mākou ma laila mea he nuiʻano o ka oscillating nenoai nona ka loa kū i ua ua hoʻopili i ka oscillatory keʻano o ka hanaʻana. Mau keʻano o ka hanaʻana i nā mea a pau a puni mākou, ka mea i emi iho i ke kahe o ka pono i loko o na kaula, malamalamaʻike manaʻo, nalu propagation, a oi. Ma ka hopena, i ke kanaka iā ia iho, a he oiaio, i ke kanaka kino, o he oscillating'ōnaehana, ka mea nona ke ola i hoʻolako 'ia e nāʻano o nā fluctuations - Kal, hanu, koko holo, lālā ana.

No laila, ka mea, e likeʻole sciences, a me ka hoʻonaʻauao 'këia. Ke simplest a mua i loko o kēia ao, ua noa kuekueni. Ka mea, i wehewehe aku ma ka exhaustion o ka ikaika vibrational o ka pana, pela no ka mea, eia ka mea hope pani, a no ka mea, e hooponoponoia ia mea, ma ka manaʻo o ka pulu ka oscillations ia fluctuations.

Ma ka oscillatory nenoai objectively ia lŘlŘ ka ikehu poho kaʻina (i loko o ÿano nenoai - no ka mea, o ke kū'ē i ka uila - ku pono i ke alo o ka uila e kū'ē'ē mai). I mea no ke aha la ka pulu ka oscillations hiki ole ke hoʻolaha like harmonic. Ua haawiia keia loiloi mua hoike, ua hiki ka hoike mathematically loko, no ka laʻana, na mechanics o ka pulu ka oscillations haʻilula hōʻike like: F = - rV = -r dx / dt. Ma keia haʻilula, R ia'ku kaʻi lau waiwai, he ikaika nui. E like me ka haʻilula, ua hiki ke manao nei makou i ka waiwai o ka māmā holo (V) no ka'ōnaehana i like i ka ia'ku waiwai. Akā, i ke alo o ka hoailona "-" 'o ia hoʻi i ka poe maʻi lele (F) a me ka mämä holo i ka like' ano.

Ana helu kaulike lua Newton Law, a me ka lawe i ka mooolelo o ka aoao o ke kŘ Ű koa, ka helu kaulike characterizes pulu ka oscillation ana kaʻina hana i na kēia palapala: ma ke alo o ka ia'ku poe i ka palapala: D ^ 2x / dt2 + 2β dt / dt + ω2 He m = 0. Ma keia haʻilula β - damping kaʻi lau waiwai, i Hōʻike i ka uku o keia pae ana o ka oscillatory kaʻina.

Muli o kona kulana hiki ke loaa like helu kaulike no ka uila kaapuni, e lawe i loko no o ka damping, a hou i kaʻaoʻao hema o ke anakahi uila e like ma ka mea pale mū holapū A Hawaiian. Wale i keia hihia, i ka palena pau helu kaulike uaʻaʻole i kākau ai no ka manawa offset (k), a me ke kauoha aku i ka Q mea pihana (Halau); kū'ē kaʻi lau waiwai R UAIAaIN e ka uila kaapuni e kū'ē'ē mai R; 2 kahi β = R / L, kahi K - kaapuni ia'ku, L - lōʻihi o ke kaula.

Inā ma ka muli o kēia mau nā papakuhikuhi, e kapili i ka like pakuhi, e ke ike i ka pakuhi o ka pulu ka oscillations ka mea i like loa kiʻi harmonic oscillations, akā, i ka ikaika hawewe o na oscillations i nā emi exponentially.

Ua haawiia i ka mea i oscillations hiki ke hana e likeʻole oscillatory nenoai a ana i loko o ka likeʻole ma o ka hana kūpono, e mea pono i ka stipulate ia, i ke ano o ka'ōnaehana mākou noʻonoʻo i loko o kēlā me kēia hihia. Mai keia ano hilinai ole wale ma kūikawā hiʻona o ka oscillatory keʻano o ka hanaʻana, akā, he mea ka e ku pono ana ia - i keʻano o nā oscillations ua nānā 'ia e ka'ōnaehana iho a me kona Mea Maluna wahi. Mākou i, ma keia hihia, noonoo iho la kekahi ma i ka waiwai o ka'ōnaehana noho kŰlń iloko o ke ao oscillatory kaʻina. No ka laʻana, ua kuhi i ke kaʻina hana 'aʻole e hoʻololi i ka elasticity o ka pūnāwai, ka ikaika o ka umekaumaha e hana ma luna o ka haawe ana, a me ka pou nenoai koe i ka ia ke kaumaha ma muli o ka ia'ku o ka māmā a me ka hoʻonui o ka oscillating loina. Oia oscillatory nenoai e haawi ia ia e like me ka laina.
