Cov yam ntxwv ntawm cov av nplaum ntuj tsim: Cov lej nce rau LCD / LED laser txiav.

Hauv kev tsim khoom LCD/LED, kev txiav laser yog ib qho txheej txheem tseem ceeb rau kev ua cov khoom sib xyaw ua ke, thiab granite, nrog nws cov khoom siv ntuj tsim tshwj xeeb, coj cov txiaj ntsig zoo rau cov txheej txheem no.

Kev tswj hwm kev co zoo heev ua kom txiav tau qhov tseeb
Thaum lub sijhawm txiav laser, kev ua haujlwm ntawm cov khoom siv tsim kev co. Txawm tias qhov kev co me me tuaj yeem ua rau muaj teeb meem xws li kev hloov pauv txoj haujlwm thiab cov npoo txiav ntxhib, cuam tshuam loj heev rau qhov zoo ntawm cov khoom. Granite muaj kev ua haujlwm damping zoo heev. Nws cov qauv pob zeb hauv av tuab sab hauv thiab kev sib cuam tshuam ntawm cov khoom me me ua rau nws nqus tau sai thiab txo qhov kev co zoo li lub tshuab nqus dej zoo. Kev tshawb fawb qhia tau hais tias cov coefficient damping sab hauv ntawm granite yog 15 npaug ntau dua li cov hlau, uas txhais tau tias thaum lub sijhawm txiav laser, nws tuaj yeem ua kom qhov kev co ntawm qib qis heev. Piv txwv li, thaum txiav cov voj voog zoo ntawm cov ntxaij vab tshaus LCD, lub hauv paus granite tuaj yeem tswj qhov kev co ntawm cov khoom siv sai sai, ua rau lub teeb laser raug tso rau qhov chaw meej thiab tswj qhov tseeb ntawm qhov txiav ntawm qib micrometer. Qhov no zoo zam qhov tsis zoo xws li luv luv lossis qhib voj voog los ntawm kev co, txhim kho qhov txiaj ntsig ntawm cov khoom.
Ua kom cov txheej txheem txiav ruaj khov thiab txuas ntxiv lub neej ua haujlwm ntawm cov khoom siv
Kev co ntau zaus tsis yog tsuas yog cuam tshuam rau qhov tseeb ntawm kev txiav xwb, tab sis kuj ua rau cov khoom siv hnav sai dua, txo lub neej ua haujlwm ntawm cov khoom siv thiab ua rau cov nqi txij nkawm nce ntxiv. Lub zog damping siab ntawm granite tuaj yeem txo qhov amplitude thiab zaus ntawm kev co thaum lub sijhawm ua haujlwm ntawm cov khoom siv, thiab txo qhov cuam tshuam thiab kev sib txhuam ntawm cov khoom. Piv txwv li, LED chip txiav. Rau cov khoom siv txiav laser uas tau siv ntau zaus, qib kev hnav ntawm nws cov khoom tseem ceeb xws li cov hlau qhia thiab cov motors raug txo qis heev nyob rau hauv qhov cuam tshuam ntawm kev co ntawm lub hauv paus granite, lub voj voog txij nkawm tau ntev dua, thiab lub neej ua haujlwm tag nrho ntawm cov khoom siv tau nce ntxiv, txuag tau ntau ntawm cov nqi hloov kho khoom siv thiab kev txij nkawm rau cov lag luam.
Txhim kho qhov ruaj khov ntawm thermal kom ntseeg tau tias qhov txiav zoo ruaj khov
Thaum lub sijhawm txiav laser, muaj cua sov ntau heev. Yog tias qhov ruaj khov ntawm cov khoom siv hauv paus tsis zoo, qhov kev hloov pauv ntawm cua sov yuav tshwm sim, uas ua rau muaj kev cuam tshuam rau qhov tseeb ntawm kev txiav. Tus coefficient ntawm thermal expansion ntawm granite qis heev, tsuas yog ib feem peb ntawm cov hlau zoo tib yam, thiab nws cov thermal conductivity tsuas yog ib feem plaub caug ntawm cov hlau zoo tib yam. Thaum lub sijhawm txiav LCD / LED laser, txawm tias qhov kub hauv zos hloov pauv sai, lub hauv paus granite tuaj yeem tswj tau qhov ruaj khov ntawm qhov ntev, zam kev hloov pauv ntawm laser los ntawm kev hloov pauv thermal, kom ntseeg tau tias cov yam ntxwv xws li qhov tob thiab dav ntawm kev txiav tseem meej txhua lub sijhawm, thiab lav qhov sib xws thiab kev ruaj khov ntawm kev txiav zoo.
Txo qhov kev pheej hmoo ntawm kev cuam tshuam thiab txhim kho kev nyab xeeb ntawm kev tsim khoom
Thaum lub zaus co ntawm cov khoom siv ze rau qhov zaus ntuj ntawm ib puag ncig sab nraud lossis nws cov khoom, resonance yuav raug ua rau. Qhov no tsis yog tsuas yog ua rau puas tsuaj rau qhov tseeb ntawm kev txiav xwb tab sis kuj ua rau muaj kev phom sij rau cov khoom siv thiab cov neeg ua haujlwm. Cov yam ntxwv ntuj tsim ntawm granite tuaj yeem hloov pauv qhov zaus co ntawm cov khoom siv thiab txo qhov tshwm sim ntawm resonance. Ntawm cov kab ntau lawm laser txiav ntawm LED modules, lub hauv paus granite tuaj yeem ua kom cov khoom siv ua haujlwm ruaj khov, txo qhov kaw tsis tau xav txog lossis cov khoom siv tsis ua haujlwm los ntawm resonance, thiab muab kev lav zoo rau kev tsim khoom nyab xeeb.

Cov yam ntxwv ntuj tsim ntawm granite ua lub luag haujlwm tseem ceeb hauv LCD / LED laser txiav los ntawm ntau qhov ntev xws li kev lav phib xaub, lub neej khoom siv, kev ruaj khov thermal thiab kev nyab xeeb ntawm kev tsim khoom, pab cov tuam txhab txhim kho lawv qhov kev sib tw hauv kev tsim khoom siab thiab tsim cov khoom zoo dua.
