Cwaningo vibration. Vibration nesilinganiso. Umthelela vibration phezu komuntu

Thina esikoleni sami baziswa isayensi njengoba physics. Iyehla iyenyuka, imvamisa, ukusheshisa - zonke lezi imiqondo ngokuqinisekile ijwayelekile kuwe. Kulesi sihloko sizoxoxa kabanzi sihloko esiqakatheke njengoba vibration. Ngamunye wethu ebhekene nale esenzeka ekuphileni kwansuku zonke.

Kuyini vibration? Incazelo inganikelwa kanje: oscillating ezinyakazayo mechanical ukuthi idluliswe ngqo emzimbeni womuntu. izici zako ezisemqoka eziphathekayo imvamisa futhi amplitude oscillation. Ukumeda vibration amplitude wenziwa amamitha noma amasentimitha, futhi imvamisa - e Hertz.

Indlela ukuhlola vibration ukusheshisa nesivinini?

ijubane futhi ukusheshisa ngokuqhubekayo ukushintshwa ngalesi zonke ukunyakaza oscillating. Ukusheshisa iyona enkulu kunazo zonke e-line isikhungo iyehla iyenyuka, futhi izikhundla kakhulu incane. Njengoba sazi lokhu, nesilinganiso vibration wenziwa phezu ukushesha kanye velocity. ngaleyo ndlela DB umbiko olwenziwa kusukela inkomba vibration (okunemibandela) ukuthi ulingana 5 ∙ Agasti ¹⁰ m / s, kanye ukusheshisa vibration - 3 ∙ Apreli ¹⁰ m / s ^2. Ukushesha kanye Velocity kuvetwa ngokuhlobene zero embundwini decibel angu. Umbono embundwini kulokhu cishe 70 dB. Imvamisa aphansi imvamisa kunyakaza akazidluli 32 Hz, futhi imvamisa high iphelile 32 Hz.

imithombo vibration

It is kabanzi ekwakheni, umkhakha, yasendlini, ezolimo, ezokuthutha, ugesi kanye mechanical, womoya amathuluzi okushisela ukusiza imishini ehlukahlukene kanye nemishini, izimoto, umshini amathuluzi. Vibration kabanzi hhayi kuphela imishini, kodwa futhi imithi ukwelapha imisipha futhi izinzwa izifo (massage vibratory, ukwelashwa vibration).

vibration nomthelela

Vibration - factor elinendawo umsebenzi okusezingeni eliphezulu begazi. Orientation, ukujula uhlobo izinguquko bokuphila izinhlelo ezihlukahlukene zomzimba womuntu zinqunywa ngezithako zawo Spectral, futhi amazinga Izakhiwo zomzimba womuntu. Indima ebalulekile nesisekelo zindlela zokusabela ukudlala analyzers - esikhumbeni, ezibukwayo, motor, vestibular, nabanye.

Kuyadingeka ukuba uqaphele indima enkulu eyadlalwa bezibona subjective vibration izakhiwo kwamakhemikhali emzimbeni womuntu. isenzo sayo emzimbeni umlamuleli ezinjengokungcoliswa umthelela ngokomzimba phezu contact, ukusakaza ezicutshini oscillation impendulo ngokushesha kwezicubu kanye nezinhlaka imiphumela, ukukhuthazwa mechanoreceptors ezibangela ukuphendula subjective futhi neyroretseptornogo.

Namuhla yazuza idatha emitholampilo zokuhlola eside kule nkinga. Vibration Ucwaningo selukhombisile ukuthi kuphakama ngaphansi kwethonya disorder wakhe motor umsebenzi okubangelwa kokubili ukulimala kwemisipha eqondile kahle isimiso sezinzwa esiyinhloko imiphumela zokulawula. I predominance izinguquko ehlasela umzimba ngesikhathi esifanayo zingachazwa ngezinqubo izinguquko ekusebenzeni izakhiwo superspinalnyh, namazwi ezimbalwa bemisipha yenziwe yaba yasendaweni izinguquko - traumatization zabo ngqo. Iningi nozwelo kunyakaza lwendawo zigaba nozwela isimiso sezinzwa esilawula ithoni imithambo neuropathy, AZ neuropathy isimiso sezinzwa okuhlotshaniswa ethintekayo kanye vibration ukuzwela.

ucwaningo Vibration akuniké ilungelo bagomela ngokuthi kwemigomo usithonye ngokuyinhloko kunqunywa orientation kuphazamiseka semithambo. Lapho kunyakaza mechanical imvamisa mkhulu kunezinhliziyo 35 Hz e capillary imihlola spastic ukwenzeka, nasekumeni ngezansi isithombe siyenzeka atony capillary. I esiyingozi kakhulu mayelana nokuthuthuka okungenzeka spasm semithambo iyisifunda imvamisa 35 kuya ku-250 Hz.

Umphumela ongemuhle lapho enza imisebenzi ukusebenza

Vibration Zingaphazamisa ukubulawa ngqo imisebenzi ukusebenza, futhi ngokungaqondile ezithinta ukusebenza komuntu, yawanciphisa. Abanye abalobi ucwaningo vibration, sikubheka njengempahla ukucindezeleka isici eqinile, okuyinto kunomphumela omubi lengqondo ukusebenza. Ngaphezu kwalokho, unesifo umsebenzi engqondo nembulunga ngokomzwelo, futhi kwandisa amathuba ezingozi.

Isivinini vibrational

Litholakala ukuthi isenzo umsindo vibration amandla emzimbeni womuntu. Ngakho-ke, lona wamuva waqala elichaza bohlu obonakaliswe amasentimitha ngesekhondi izinga vibrational noma ulinganiswa decibel angu, kanye umsindo. Evamile ke bokutholwa embundwini mechanical kunyakaza isivinini ingxenye ∙ 5 10 ⁶ cm / umzuzwana. Kuphela ngokusebenzisa ukuxhumana ngqo ukuqhaqhazela umzimba emzimbeni noma ngokusebenzisa nezinye izindikimba eziqinile naye wazizwa (beqonda) kunyakaza lokukhanda. Uma ukuxhumana umthombo wabo, eshicilelwe (Generating) bass umsindo, vibration (imvamisa aphansi), kanye umsindo njengoba ziqondakala abangele ukulimala ebuchosheni.

Jikelele kanye lendawo

Hlukanisa vibration jikelele kanye lendawo kuncike Lokusakaza kunyakaza mechanical izingxenye zomzimba womuntu. Lapho ngaphansi ukushaqeka kuphela ingxenye yendawo umzimba ngqo nabo ebusweni, okuyinto uyazamazama. Ngokuvamile kuba izandla. Lokhu kwenzeka uma usebenzisa amanye amathuluzi isandla noma ubambe izingxenye umshini nezinye izinto ngithuthumela.

vibration Local ngezinye izikhathi adluliselwa izitho zomzimba, ezixhunywe ne amalunga omzimba ngokuqondile wadalula kwezinengi zezitho zakhe. Kodwa amplitude idatha oscillation kwesitho somzimba ngokuvamile aphansi ngoba njengoba ukudluliswa kwezicubu (soft ikakhulukazi) oscillations kuthiwa damped kancane kancane. Kunalokho, vibration jikelele kuthinta wonke umzimba. Lokhu kwenzeka ikakhulu phezu oscillations mechanical, lapho isisebenzi.

womoya isando isifo

Lapho obala komuntu vestibular ezishukumisa bezibona ukuhlolwa kanye nesikhathi eshaywe, futhi yehlise processing speed. Incoordination kubangele ongaphakeme-imvamisa kunyakaza. ngaleyo ndlela Izinguquko buphawuleka kakhulu obaphawuleka amaza ku ezahlukene 4 kuya ku-11 Hz.

Ngu izinguquko sokugembula ziphikelele umzimba womuntu okuholela ukuvezwa kwesikhathi eside vibration. ukuhlaziywa olunzulu inqubo sokugembula kuye kwaholela ngokwahlukana yayo kwifomu ahlukene nosological yesifo emsebenzini - isifo vibration. Uyaqhubeka ukubamba isikhundla aholayo phakathi ezinye izifo emsebenzini. Ukusetshenziswa Its kuphakamisa nezimfuneko zokulawula wemishini ngesandla, kanye lunye okwandisa zomsebenzi, okuholela ekwandeni nesikhathi esiphelele ukuchayeka kunyakaza mechanical emzimbeni. Nge ukwanda ubude kanye ukushuba ukuchayeka vibration kwandisa amathuba asathuthuka lesi sifo. ukubaluleka okuphawulekayo ukuzwela umuntu. Ukukhathala, ukubanda, umsindo, ukudakwa, imisipha ukungezwani, nabanye. Gcizelela imiphumela emibi.

Isiteji isifo vibration

Ukunikeza 4 izigaba kobukhulu isifo:

- primary (I);

- ngokulinganisela uzwakalise (II);

- liphinyiselwe (III);

- generalized (IV, kuyinto evamile).

Umthelela ongemuhle vibration jikelele

Inani ongaphakeme-imvamisa nokudludliza, ikakhulukazi resonant band, kungadala eside ukuhlukumezeka ukuze amathambo futhi intervertebral disk ukufuduka izitho kubekwe phakathi komgodi ongaphakathi kwamathumbu, kanye ubuhlungu, izinguquko esiwohlozayo yomgogodla, kolwelwesi okungamahlalakhona, kanye nabanye.

Ngihlupheke isikhathi eside imiphumela enjalo abesifazane baye banda imvamisa izifo gynecological, preterm zabasebenzi, isisu nokuguqulwa. Low-imvamisa vibration kwabesifazane kubangela kahle kwegazi kwezitho okhalo.

Ukuvevezela Mechanical ezakhiweni

ucwaningo Vibration kubaluleke kakhulu ukuba afeze hhayi kuphela e izakhiwo zezimboni, kodwa futhi emakhaya. Iqiniso ukuthi simele ingozi hhayi nje kuphela abasebenzi kodwa ngoba namanye amaqembu abantu. Ngo izakhiwo zokuhlala, vibration nemiphumela yomuntu ngokusebenzisa izitshalo zezimboni, ezokuthutha, ubunjiniyela kanye imishini kwezobuchwepheshe. Umthelela kakhulu emzimbeni we oscillation umfutho idolobha izitimela: Railways umugqa, ezindaweni komhlaba edalulwa.

Ezivela ukuhamba izitimela e izakhiwo vibration kuyinto ejwayelekile ngakanye. I amplitude oscillation ne ibanga kusuka lwaluvelaphi incipha. Ekhulumela ukusatshalaliswa iyehla iyenyuka phezu izibuya multi-storey izakhiwo, kumele ukuthi esiqongweni kungenzeka, kuncike resonance, njengoba ukuqiniswa kanye buthakathaka vibration. Kulokhu, nezinhlobo zosizo akudingeki ezakhiwe e izimo kwenhlabathi efanayo nomthelela obalulekile amazinga endaweni yokuhlala. Ngezinye izikhathi zinomswakama vibrational sezakhiwo elise imishini yezobuchwepheshe-zobuchwepheshe kakhulu (zommbila), kanye netintfo esishunyekiwe.

izindlela yokuvikela

Vibration ukumelana kubaluleke kakhulu emsebenzini. Edamu amazinga ayo, ehlanzekile, linesisekelo esifanele, - ngesisekelo ukuvimbela izifo vibration. Kucatshangelwe kule ndaba, isimo, ubude isinyathelo. Ngo RF umthetho sanitary ulawula amazinga kunyakaza mechanical, okuyinto kufanele ihambisane emsebenzini.

Ukuvikelwa ngomphefumulo umzimba vibration

Umthelela vibration ku umuntu kufanele okungenani zingancishiswa. Ukuphepha is a uhlelo izici ambalwa kanye qualitative imingcele athonya izakhi ngokucacile, ukuqinisekisa ukungabi khona imiphumela deleterious ka kunyakaza mechanical emzimbeni womuntu. Vibration ukumelana inikezwa yi:

- usebenzisa imishini vibrobezopasnyh;

- ukusetshenziswa ukuvikelwa ngokukhethekile vibration;

- ekuklanyweni kwezakhiwo ukukhiqizwa futhi izinqubo ukuqinisekisa ukuthi ukuhambisana namazinga impilo uma sebangena emsebentini;

- izinyathelo lwenhlangano lobuchwepheshe okuhloswe ngaso - ekuthuthukiseni ukusebenza izimoto ezisetshenziswa, inhlangano ukulungiswa kwabo ngesikhathi esifanele, kanye nokulawula vibration nemingcele;

- ukudalwa imibuso kahle umsebenzi futhi ukuphumula.

PPE isetshenziswa lapho zihlatshwa ngomphefumulo umzimba vibration - lokhu vibration ukuzihlalela izicathulo, amathe, insoles. Indlela ephumelela kunazo zonke amakhambi kungaba kubhekwe nokuqedwa nomuntu ngqo imishini nangokuthuthumela. Lokhu kufezwa ngezinkathi zezikhathi ngokusebenzisa asebenza ezimbonini, elawulwa kude, esikhundleni ezishintshayo imisebenzi.

Esebenzisa ukuvikelwa vibration wendawo

Ukuncishiswa umthelela walo omubi kufinyelelwa:

- ngokunciphisa ngegalelo lako ngqo emthonjeni (nokusetshenziswa izingalo noma antivibration kudivayisi Damping);

- ngokusebenzisa Ukuvikelwa zangaphandle, okungukuthi amadivayisi nokunwebeka-Damping futhi izinto ezibekwe phakathi ezandleni opharetha futhi umthombo kunyakaza mechanical (anti-vibration amagilavu, mitts, pads kanye liner).

Indima ebalulekile eyinkimbinkimbi izinyathelo ezihlose ukunciphisa umthelela ongemuhle vibration emzimbeni womuntu, owanikwa izindlela umsebenzi kanye nokuphumula. Isikhathi Imininingwane yokuxhumana nalo, ngokuvumelana mode ukusebenza kufanele igcine ngesikhathi shift. amakhefu ezimbili Kunconywa ukulapha umzimba, ukuzilibazisa nokunye. d. Isikhathi ngowokuqala kufanele kube amaminithi 20 (lokhu ikhefu kumele inikezwe 2 amahora ngemva kokuqala ushintsho). Isikhathi kwesibili - imizuzu engu-30, kufanele kube amahora angu-2 emva sekhefu lasemini. Sekhefu ngesikhathi esifanayo akufanele kuhlale ngemizuzu engaphansi kuka-40. Isikhathi ukuchayeka ngokuqhubekayo ukuze umzimba alahlwayo oscillation mechanical kufanele abe ngaphezulu imizuzu 10-15.

Ukuze impilo wokwakha kanye nokungenelela bezokwelapha, ekhonza ukuze ukuvimbela izifo vibration, kubandakanya lokhu okulandelayo:

- gidroprotsedury isandla (okugeza ngamanzi ashisayo (37-38 degrees +) noma ukusebenzisa ezomile emoyeni Ukushisa;

- yokuzijwayeza ukukhiqizwa;

- self-massage and vzaimomassazh ehlombe ngebhande izandla;

- Imisebe yama-UV;

- nokusetshenziswa kwamavithamini, kanye neminye imisebenzi tonic uhlamvu (i-oksijini cocktail Igumbi wokukhululeka ngokwengqondo, njll).

Ukubaluleka kanye ukuhlobana lesi sihloko kuqinisekiswa yokuthi ucwaningo yayo esikoleni. Vibration kubhekwa, ikakhulukazi, encwadini yakhe "Physics" (grade 11). Yiqiniso, esikoleni efunda ngendlela ajwayelekile. Uyazicabangela, ikakhulukazi, vibration Zomhlaba. Imvamisa iplanethi yethu ilingana 7,83 Hz. Lokhu ubuningi ubizwa ngokuthi amagagasi Schumann noma Schumann resonance imvamisa. Nokho, abanye bakholelwa ukuthi ushintsho kamuva vibration Zomhlaba. Ngokwesibonelo, Anka Dinke oyisazi-Romanian, sathi ngo-December 2012 ababenakho ukufinyelela 12,6-12,8 Hz. vibration ongumuntu kufanele luhambisane kunyakaza planethi. Labo bayakwazi tune ku frequencies entsha ngeke igcine ngokuzuzisa ngokomoya, njengoba kusikisela Anka Dinke. vibration Human - ngesihloko for esinye isihloko.
