G yog ib chav tsev feem ntau siv los piav txog qhov amplitude ntawm kev vibration hauvvibration motorsthiab linear resonant actuators.Nws sawv cev rau qhov acceleration vim lub ntiajteb txawj nqus, uas yog kwv yees li 9.8 meters ib ob squared (m/s²).
Thaum peb hais tias kev vibration theem ntawm 1G, nws txhais tau hais tias qhov kev co amplitude yog sib npaug rau qhov acceleration ib yam khoom uas tau ntsib vim lub ntiajteb txawj nqus.Qhov kev sib piv no tso cai rau peb nkag siab qhov kev siv zog ntawm kev vibration thiab nws cov kev cuam tshuam rau lub cev lossis daim ntawv thov tam sim no.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias G tsuas yog ib txoj hauv kev qhia qhov amplitude ntawm kev vibration, nws kuj tuaj yeem ntsuas hauv lwm chav xws li meters ib ob squared (m / s²) lossis millimeters ib ob squared (mm / s²), nyob ntawm cov kev cai tshwj xeeb lossis tus qauv.Txawm li cas los xij, siv G ua ib chav tsev muab cov ntsiab lus qhia meej thiab pab cov neeg siv khoom nkag siab txog qib kev co hauv txoj hauv kev.
Dab tsi yog vim li cas rau kev tsis siv kev txav chaw (mm) lossis quab yuam (N) raws li kev ntsuas ntawm kev vibration amplitude?
Kev vibration motorsfeem ntau tsis siv ib leeg.Lawv feem ntau muab tso rau hauv cov tshuab loj nrog rau cov phiaj xwm loj.Txhawm rau ntsuas kev vibration amplitude, peb mount lub cev muaj zog ntawm lub hom phiaj paub thiab siv lub accelerometer los sau cov ntaub ntawv.Qhov no ua rau peb pom cov duab pom tseeb ntawm tag nrho cov yam ntxwv kev co ntawm lub system, uas peb mam li qhia rau hauv daim duab qhia kev ua tau zoo.
Lub zog quab yuam los ntawm kev co lub cev muaj zog yog txiav txim siab los ntawm qhov sib npaug hauv qab no:
$$F = m \times r \times \omega ^{2}$$
(F) sawv cev rau lub zog, (m) sawv cev rau qhov loj ntawm eccentric loj ntawm lub cev muaj zog (tsis hais txog ntawm tag nrho cov system), (r) sawv cev rau eccentricity ntawm eccentric huab hwm coj, thiab (Ω) sawv cev rau qhov zaus.
Nws yuav tsum raug sau tseg tias tsuas yog lub zog vibration ntawm lub cev muaj zog tsis quav ntsej txog kev cuam tshuam ntawm lub hom phiaj loj.Piv txwv li, ib qho khoom hnyav dua yuav tsum muaj zog ntau dua los tsim tib theem ntawm kev nrawm raws li cov khoom me me thiab sib dua.Yog li yog tias ob lub khoom siv tib lub cev muaj zog, cov khoom hnyav dua yuav vibrate mus rau qhov me me, txawm tias cov motors tsim tib lub zog.
Lwm qhov ntawm lub cev muaj zog yog qhov vibration zaus:
$$ f = \frac{Motor \: Ceev \:(RPM)}{60}$$
Kev hloov pauv los ntawm kev vibration yog cuam tshuam ncaj qha los ntawm qhov zaus ntawm kev co.Nyob rau hauv lub vibrating ntaus ntawv, quab yuam ua cyclically ntawm lub system.Rau txhua lub zog siv zog, muaj qhov sib npaug thiab sib npaug zog uas nws thiaj li tso tseg.Thaum qhov zaus ntawm kev vibration yog siab dua, lub sij hawm ntawm qhov tshwm sim ntawm kev tawm tsam rog txo.
Yog li ntawd, lub kaw lus muaj tsawg lub sij hawm yuav tsum tau tsiv tawm ua ntej tawm tsam rog tshem tawm nws tawm.Tsis tas li ntawd, ib qho khoom hnyav dua yuav muaj qhov hloov me me dua li cov khoom sib zog thaum raug rau tib lub zog.Qhov no zoo ib yam li cov txiaj ntsig tau hais ua ntej txog kev quab yuam.Ib yam khoom hnyav dua yuav tsum muaj zog ntau dua kom ua tiav qhov kev hloov pauv zoo ib yam li cov khoom sib zog.
