Vibration Frequency vs Vibration tshwm sim

Hauv kev sib tham txhua hnub, peb feem ntau xa mus rau ib qho kev vibration nkaus xwb li "kev vibrations." Piv txwv li, tej zaum koj yuav hais tias koj lub xov tooj vibrates thaum koj tau txais cov ntawv xov xwm, los yog qhov screen kov " vibrates" luv luv thaum koj coj mus rhaub nws, thiab ob zaug thaum koj nias thiab tuav nws. Hauv kev muaj tiag, txawm li cas los xij, txhua qhov kev cuam tshuam no muaj ntau pua lub voj voog hloov pauv tshwm sim hauv ib qho piv txwv.

Nws yog ib qho tseem ceeb kom paub tias kev co yog qhov tseem ceeb ntawm kev rov ua dua thiab hloov pauv raws sijhawm. Nyob rau hauv ib qho eccentric rotating huab hwm coj (ERM) kev co lub cev muaj zog, qhov kev hloov no tshwm sim nyob rau hauv ib tug angular yam li lub loj rotates. Nyob rau hauv sib piv, ib tug linear resonant actuator (LRA) ua hauj lwm nyob rau hauv ib tug linear yam, nrog ib tug loj tsiv rov qab mus rau lub caij nplooj ntoos hlav. Yog li ntawd, cov cuab yeej no muaj kev vibration zaus uas cuam tshuam qhov oscillatory xwm ntawm lawv cov kev hloov pauv.

Txhais cov ntsiab lus

Kev vibration zaus yog ntsuas hauv Hertz (Hz). Rau ibEccentric Rotating Mass (ERM) lub cev muaj zog, lub cev muaj zog ceev hauv revolutions ib feeb (RPM) muab faib los ntawm 60. Rau aLinear Resonant Actuator (LRA), sawv cev rau resonant zaus teev nyob rau hauv daim ntawv teev cov ntaub ntawv.

Nws yog actuators (ERMs thiab LRAs) uas muaj kev vibration zaus, muab tau los ntawm lawv qhov ceev thiab kev tsim kho.

Vibration tshwm sim yog tus naj npawb ntawm lub sij hawm vibration nyhuv yog qhib nyob rau hauv ib tug muab lub sij hawm. Qhov no tuaj yeem qhia tau hais txog cov teebmeem hauv ib ob, ib feeb, ib hnub, thiab lwm yam.

Nws yog cov ntawv thov uas muaj kev vibration tshwm sim, qhov twg cov nyhuv vibration tuaj yeem ua si ntawm lub sijhawm tshwj xeeb.

Yuav ua li cas sib txawv thiab ua tiav qhov tshwj xeeb vibration zaus

Kev sib txawv ntawm qhov vibration zaus yog qhov yooj yim heev.

Cias muab:

Lub vibration zaus yog ncaj qha ntsig txog lub cev muaj zog ceev, uas cuam tshuam los ntawm kev siv hluav taws xob. Txhawm rau kho qhov vibration zaus, qhov siv hluav taws xob tuaj yeem nce lossis txo. Txawm li cas los xij, qhov voltage yog txwv los ntawm qhov pib voltage thiab qhov ntsuas hluav taws xob (lossis siab tshaj qhov ntsuas hluav taws xob rau lub sijhawm luv), uas nyob rau hauv lem txwv qhov kev vibration zaus.

Sib txawv vibration motors nthuav tawm cov yam ntxwv tshwj xeeb raws li lawv cov khoom tso tawm torque thiab eccentric pawg tsim. Tsis tas li ntawd, qhov kev vibration amplitude kuj cuam tshuam los ntawm lub cev muaj zog ceev, uas txhais tau tias koj tsis tuaj yeem kho qhov vibration zaus thiab amplitude ntawm nws tus kheej.

Lub hauv paus ntsiab lus no siv rau ERMs, LRAs muaj qhov kev vibration ruaj khov hu ua lawv Resonant zaus. Yog li ntawd, ncav cuag ib qho kev vibration zaus yog sib npaug ua rau lub cev muaj zog khiav ntawm ib qho kev ceev.
