Ịmụ ihe n'ibu vibrations

Around anyị anụ ahụ Ụwa jupụtara ije. Fọrọ nke nta-agaghị ekwe omume chọta dịkarịa ala otu anụ ahụ, nke nwere ike na-ahuta ka ịbụ na ike. E wezụga evenly-atụ rectilinear ngagharị, ukporo nke a mgbagwoju trajectory, ije osooso na ndị ọzọ, anyị nwere ike na-edebe ihe mbụ aka, ma ọ bụ na-ata ahụhụ mmetụta nke ntighari mmegharị na ihe anụ.

Nwoke ahụ chọpụtara na pụrụ iche atụmatụ na e ji mara oscillatory mmegharị, na ọbụna mụtara iji n'ibu vibrations ka ha onwe ha na nzube. All oge ugboro ugboro oge Filiks nwere ike kwuru vibrations. Mechanical vibrations bụ nanị otu akụkụ nke iche iche phenomena nke ụwa, na-ewere ọnọdụ na ihe fọrọ nke nta otu iwu. On a visual atụ nke n'ibu ugboro ugboro mmegharị nwere ike ime ka ndị bụ isi na iwu na iji chọpụta iwu ahụ sitere akpa, electromechanical na ndị ọzọ na oscillatory Filiks.

Ọdịdị nke n'ibu oge oscillations bụ na akakabarede nke nwere ume kinetic ike. Iji kọwaa ihe atụ nke otú ike akakabarede na-ewe ebe site n'ibu vibrations nwere ike ịbụ, na-atụle na bọl, kwụsịtụrụ na a spring. Na Zuru ike nke ike ndọda na-guzozie eguzozie site na-agbanwe ike nke mmiri. Ma, ọ dị mkpa iji mee ka usoro nke itule ike, si otú akpali ije nke a n'akụkụ nke n'ókè nke ịha, dị ka ndị nwere ike ga-amalite ya mgbanwe n'ime kinetic ike. Na na, n'aka, si oge nke na-agafe na obi ụtọ efu ọnọdụ amalite ike converted n'ime nwere. Usoro a na-ewe ebe ogologo oge dị ka ọnọdụ nke ịdị adị nke usoro nso enweghị ntụpọ.

Mathematically atụle ezigbo fluctuations aa na-enweghị ma ọ bụ cosine ọrụ. Ndị dị otú ahụ Filiks na-akpọ harmonic oscillations. The ezigbo ihe atụ nke n'ibu ngagharị bụ harmonic oscillations nke pendulum na nnọọ agụụ, mgbe e nweghị mmetụta nke esemokwu agha. Ma, ọ bụ nnọọ ihe na-enweghị ntụpọ ikpe, iji nweta nke bụ nyochawa nnọọ ike.

Mechanical vibrations, n'agbanyeghị ha oge, n'oge ọ kwụsị, na usoro enyene a ọnọdụ nke ikwu ịha. Na nke a emee ruru n'efu nke ike imeri ikuku eguzogide, esemokwu na ihe ndị ọzọ, ga-apụghị izere ezere na-eduga onye ukpụhọde nke mgbawa na mgbanwe site na ezigbo kpọmkwem ọnọdụ nke bụ usoro na ajụjụ.

Inexorably nso ka ọmụmụ ihe miri emi na analysis, anyị kwesịrị mathematically akọwa n'ibu vibrations. Formula usoro a na-agụnye quantities dị ka njupụta (A), na oscillation ugboro (w), mbụ frasi (a). A ọrụ nke Ndahie (X) vesos oge (t) nwere n'ụdị a oge gboo ụdị

x = Acos (wt + a).

Ọ bụkwa uru banyere uru ihe e ji mara n'ibu vibrations, inwe aha - na oge (T), nke a na-kọwaa mathematically ka

T = 2π / w.

Mechanical vibrations, na mgbakwunye na nke nọchiri ihu nke na-abụghị n'ibu nkọwa nke Filiks nke ọdịdị oge, anyị nwere mmasị ụfọdụ nke Njirimara na, mgbe eji n'ụzọ kwesịrị ekwesị, nwere ike inye uru ụfọdụ, na ọ bụrụ na ekpe unattended, - edu ndú ka ịrịba nsogbu.

Special ntị ga-akwụ ụgwọ iji onu nke a nkọ ịrị elu na njupụta nke amanye oscillations abịa mgbe ugboro nke mmetụta nke na-akwọ ụgbọala ike ugboro nke oscillations nke ahu. Ọ na-akpọ resonance. Ọtụtụ-eji ngwá electronic, n'ibu usoro, resonance onu na tumadi gosipụtara ebibi uwa, ọ ga-atụle mgbe na-eke a dịgasị iche iche nke n'ibu owuwu na usoro.

A n'ihu ngosipụta nke n'ibu vibrations bụ a vibration. Ọdịdị ya nwere ike ọ bụghị naanị na a na-erughị ala, kamakwa ime ka omume nke resonance. Ma, e wezụga ndị na-ezighị ezi mmetụta, obodo vibrations na ala ike nke mgbaàmà nwere ike mma-emetụta n'ozuzu na ahụ mmadụ, rụọ ọtọ ala nke Central ụjọ usoro, na ọbụna mee ngwangwa ndị na-agwọ ọrịa nke ọnyá , wdg

Ọzọ embodiments ngosipụta nke n'ibu oscillations nwere ike ịmata ihe dị iche ụda onu ultrasound. Bara uru n'ibu Njirimara ndị a mmiri na ebili mmiri na ndị ọzọ na-egosi na n'ibu oscillations na-n'ọtụtụ ebe dị iche iche ubi nke mmadụ ọrụ.
