Kudzidza zvemaziso vibrations

Around isu kwomuviri nyika izere kufamba. Zvinenge zvisingaiti kungowanawo imwe muviri, izvo zvinogona sechinoitika kuva pa zororo. Kunze zvakaenzana mberi rectilinear inofamba, rakaramba munhu kunzwisisa trajectory, kufamba kumhanyisa uye vamwe, tinogona kuchengeta ruoko wokutanga, kana vanotambura matambudziko idzokororo fambisa zvokunyama zvinhu.

Murume akanga akacherechedza nevamwe zvinhu uye maitiro oscillatory kufamba, uye kunyange vakadzidza kushandisa zvemaziso vibrations nokuda kwezvinangwa zvavo. All nguva nenguva nekorasi nguva pezvakaitwa anogona kutaurwa vibrations. Mechanical vibrations ndivo chete chikamu siyana mananara nyika, kuitika anongoda mitemo chete. On a chinooneka muenzaniso zvemaziso yokudzokorora. fambisa anogona kuita dzinokosha mitemo uye kuona mitemo kuti tinobva remagetsi, electromechanical uye zvimwe oscillatory kwendangariro.

Yezvakaita zvemaziso nguva nenguva oscillations ari kutendeuka zvinogona simba kupinda kinetic simba. Kurondedzera muenzaniso sei simba kutendeuka kunoitika nomuviri vibrations zvinogona, kukurukura bhora, yakaturikwa pamusoro chitubu. In azorore simba regiravhiti iri mikwende nokuda kwakavharwa nenyama simba remvura. Asi zvinokosha kuunza hurongwa kubva nepakati simba, saka triggering sangano rimwe divi pfungwa zvakanyatsoenzana, sezvo zvinogona simba ichatanga Kushandurwa yawo kinetic simba. Uye kuti, uyewo, kubva nguva kupfuura bhora razero nzvimbo anotanga kutendeukira kupinda kwaniso. Izvi zvinotora nzvimbo saka chero bedzi zvinhu chokuvapo wegadziriro pedyo kwakakwana.

Mathematically vaiona akanaka nokufamba kuitika pamusoro sine wave kana cosine chaitika. pezvakaitwa yakadaro inonzi harmonic oscillations. The akakodzera muenzaniso zvokuimba inofamba ndiye harmonic oscillations pakati zvakavamba kuchinja mune zvachose Vacuum, kana pasina simba kukweshera mauto. Asi zviri zvachose mhosva nyaya, kuti vabudirire riri pamutemo chakaoma chaizvo.

Mechanical vibrations, kunyange zvavo nguva, pakupedzisira agumisa uye hurongwa ane nzvimbo ine hama zvakanyatsoenzana. Izvi kunoitika nokuda kutambisa simba kukunda mhepo nemishonga, kukweshera uye zvimwe zvinhu, vaizongoguma kutungamirira kugadziridzwa ari Masvomhu ari kuchinja kubva YAKANAKA ezvinhu zvomene umo mune wemuTesitamende mubvunzo.

Zvisingadzoreki pedyo kudzidza zvakadzama uye pachisara tinofanira mathematically kurondedzera zvemaziso vibrations. Mutoo uyu muitiro anosanganisira zvizhinji zvakadai amplitude (A), kuti oscillation kakawanda (w), Paunotanga (a). A kushanda misha (X) maringe nguva (T) ane chimiro dzekare chimiro

x = Acos (wt + a).

Uyewo zviripo kudoma ukoshi zvinoratidza zvemaziso vibrations, ane zita - nguva (T), iro kunotsanangurwa mathematically sezvo

T = 2π / w.

Mechanical vibrations, kuwedzera maonero vasiri zvokuimba rondedzero dzinotsanagura zvakasikwa kuzeza tiri kuziva zvimwe zvivako kuti, kana ikashandiswa zvakanaka, inogona kupa zvimwe zvinobatsira, uye kana akasiya vasina akavatarisa, - mutobvu kuti inokosha dambudziko.

Special kutarisirwa inofanira kubhadharwa kuti Chiitiko munhu unopinza achamuka amplitude iri kumanikidzwa oscillations kuuya apo kakawanda matambudziko kufambisa simba kuti kakawanda pakati oscillations muviri. Inonzi resonance. Zvinowanzoshandiswa zvemagetsi, zvemaziso hurongwa, resonance chiri ainyanya kwakaratidzwa rokuparadza hunhu, inofanira kukurukurwa paaisika dzakasiyana-siyana zvemaziso hurongwa uye hurongwa.

Chimwe kuratidza zvemaziso vibrations chinhu vibration. Chitarisiko Its inogona kwete chete imwe kusanzwa, asiwo kuti panowanikwa resonance. Asi kunze inokanganisa, zvomunharaunda vibrations vane yakaderera kusimba zvingaratidza zvakanaka kufurira kwose pamusoro womunhu, kuvandudza dzichipfekeka mamiriro epfungwa, uye kunyange kuwedzera maronda , etc.

Zvimwe embodiments kuratidza zvemaziso oscillations vanogona kusiyanisa inzwi chaiyo Ultrasound. Kubatsira zvemaziso ehupfumi nemafungu izvi uye zvimwe zvinoratidza zvemaziso oscillations zvinonzi nevakawanda kushandiswa muminda mabasa evanhu akasiyana.
