Hauv kev lag luam roj teeb lithium, raws li cov khoom siv tseem ceeb, kev ruaj ntseg ntawm lub zog txav ntawm lub tshuab txheej ua lub luag haujlwm txiav txim siab hauv kev tsim cov roj teeb lithium. Nyob rau hauv xyoo tas los no, ntau lub lag luam roj teeb lithium tau pom tias thaum txhim kho lawv cov khoom siv, tom qab hloov cov tsoos cam khwb cia hlau puag nrog granite puag, kev ruaj ntseg ntawm lub platform txav tau ua tiav qhov zoo. Raws li cov kev ntsuam xyuas tiag tiag, qhov kev txhim kho kev ruaj ntseg tau mus txog siab li 200%. Tom ntej no, peb yuav delve rau hauv cov laj thawj qab nws. cov
Qhov sib txawv ntawm cov khoom vaj khoom tsev nteg lub hauv paus rau stability
Thermal stability: Granite muaj qhov zoo heev
Thaum lub sij hawm ua hauj lwm ntawm lub lithium roj teeb txheej tshuab, yam xws li lub cev muaj zog khiav thiab tshav kub generated los ntawm kev sib txhuam yuav ua rau fluctuations ntawm kub nyob ib ncig ntawm cov khoom. Cov coefficient ntawm thermal expansion ntawm cam khwb cia hlau yog kwv yees li 12 × 10⁻⁶ / ℃, thiab nws qhov loj me hloov pauv thaum kub sib txawv. Piv txwv li, thaum kub nce los ntawm 10 ℃, 1-meter ntev cam khwb cia hlau puag yuav elongate los ntawm 120μm. Lub coefficient ntawm thermal expansion ntawm granite yog tsawg heev, tsuas yog (4-8) × 10⁻⁶ / ℃. Nyob rau tib lub sijhawm, qhov elongation ntawm 1-meter-ntev granite puag tsuas yog 40-80μm. Lub thermal deformation me ntsis txhais tau hais tias nyob rau hauv ib puag ncig ntau lawm nrog qhov kub thiab txias hloov, lub hauv paus granite tuaj yeem tswj tau qhov tseeb thawj zaug ntawm lub platform txav thiab xyuas kom muaj kev ruaj ntseg ntawm txheej txheej txheej. cov
Rigidity thiab damping kev ua tau zoo: Granite yog superior
Rigidity txiav txim siab cov khoom muaj peev xwm los tiv thaiv deformation, thaum damping kev ua tau zoo cuam tshuam nrog kev ua haujlwm ntawm kev nqus lub zog. Txawm hais tias cam khwb cia hlau muaj qee yam rigidity, nws muaj cov qauv flaky graphite hauv. Raws li kev ua haujlwm ntev ntawm kev hloov pauv kev ntxhov siab tsim los ntawm cov khoom siv ua haujlwm, nws yog qhov ua rau muaj kev ntxhov siab, ua rau deformation thiab cuam tshuam rau kev ruaj ntseg ntawm lub platform. Nyob rau hauv sib piv, granite yog ib qho nyuaj nyob rau hauv kev ntxhib los mos, muaj ib tug ntom sab hauv qauv thiab zoo heev rigidity. Nws cov qauv ntxhia tshwj xeeb endows nws nrog kev ua tau zoo damping, ua kom nws hloov pauv kev vibration sai rau hauv thermal zog rau dissipation. Cov kev tshawb fawb tau pom tias nyob rau hauv ib puag ncig kev co ntawm 100Hz, granite tuaj yeem txo qhov kev vibration hauv 0.12 vib nas this, thaum cam khwb cia hlau yuav tsum 0.9 vib nas this. Thaum lub lithium roj teeb txheej tshuab ua haujlwm ntawm kev kub ceev, lub hauv paus granite tuaj yeem txo qhov cuam tshuam ntawm kev co ntawm lub taub hau txheej, kom ntseeg tau tias cov xim zoo sib xws thiab cov tuab tuab. cov
Quantitative cov ntaub ntawv txhawb kev txhim kho kev ruaj ntseg
Vibration test: Lub amplitude contrast yog txawv
Cov koom haum tshaj lij tau ua cov kev ntsuam xyuas kev vibration ntawm cov kev taw qhia ntawm lithium roj teeb txheej tshuab nruab nrog cam khwb cia hlau bases thiab granite bases feem. Thaum lub tshuab txheej ua haujlwm ib txwm ua thiab qhov ceev yog teem rau ntawm 100m / min, lub siab-precision vibration sensor yog siv los ntsuas qhov amplitude ntawm qhov tseem ceeb ntawm lub platform. Cov txiaj ntsig tau pom tias qhov amplitude ntawm cam khwb cia hlau puag txav platform yog 20μm hauv X-axis kev taw qhia thiab 18μm hauv Y-axis kev taw qhia. Tom qab hloov nrog lub hauv paus granite, qhov amplitude ntawm X-axis txo mus rau 6μm thiab qhov Y-axis txo mus rau 5μm. Los ntawm cov ntaub ntawv amplitude, nws tuaj yeem pom tau tias lub hauv paus granite tau txo qhov kev vibration amplitude ntawm lub txav platform hauv ob lub ntsiab lus qhia los ntawm kwv yees li 70%, txo qhov cuam tshuam ntawm kev co ntawm cov txheej txheej thiab muab pov thawj muaj zog rau kev txhim kho kev ruaj ntseg. cov
Kev saib xyuas qhov tseeb ntev ntev: Kev loj hlob qeeb qeeb
Thaum lub sijhawm 8-teev txheej txheej ua haujlwm tas mus li, qhov chaw raug ntawm lub platform tau saib xyuas hauv lub sijhawm. Thaum siv lub hauv paus hlau cam khwb cia, qhov chaw yuam kev ntawm lub platform maj mam nce lub sijhawm. Tom qab 8 teev, qhov yuam kev ntawm qhov chaw ntawm XY axes ncav cuag ± 30μm. Qhov kev ua yuam kev ntawm kev txav ntawm lub platform nrog granite puag tom qab 8 teev tsuas yog ± 10μm. Qhov no qhia tau hais tias thaum lub sij hawm ntev kev tsim khoom, lub hauv paus granite tuaj yeem tswj tau qhov tseeb ntawm lub platform, kom tsis txhob muaj qhov sib txawv ntawm txheej txheej los ntawm qhov tseeb drift, thiab ntxiv kom paub meej tias nws qhov kev ruaj ntseg zoo dua. cov
Kev ruaj ntseg ntawm qhov tseeb cov nyhuv pov thawj tau raug txhim kho
Ntawm cov kab ntau lawm ntawm qee yam lithium roj teeb tsim lag luam, cov cam khwb cia hlau puag ntawm qee lub tshuab txheej tau hloov kho rau granite hauv paus. Ua ntej kev txhim kho, qhov tsis xws luag ntawm cov khoom yog siab li 15%, nrog rau qhov tsis xws luag xws li txheej txheej tsis sib xws thiab txheej txheej sib txawv ntawm ntug ntawm daim ntawv electrode. Tom qab kev txhim kho, qhov tsis xws luag ntawm cov khoom poob qis rau 5%. Tom qab kev tsom xam, nws yog qhov tseeb vim tias lub hauv paus granite txhim kho kev ruaj ntseg ntawm lub platform txav uas cov txheej txheem txheej ua ntau dua thiab tswj tau, txo cov khoom tsis zoo los ntawm cov platforms tsis ruaj khov. Qhov no qhia tau hais tias muaj kev cuam tshuam zoo ntawm granite puag ntawm kev tsim khoom zoo hauv lithium roj teeb txheej tshuab. cov
Hauv kev xaus, txawm hais tias nws yog los ntawm kev tshawb fawb theoretical ntawm cov khoom siv, cov ntaub ntawv ntsuas qhov tseeb, lossis cov lus pom zoo ntawm cov kab ntau lawm, nws pom tseeb tias kev txhim kho kev ruaj ntseg ntawm lithium roj teeb txheej tshuab lub suab platform siv granite puag piv rau cam khwb cia hlau puag tuaj yeem ncav cuag 200%. Rau lithium roj teeb raug lag luam uas nrhiav kev ua tau zoo thiab muaj peev xwm, lub hauv paus granite yog undoubtedly ib qho tseem ceeb xaiv los txhim kho kev ua tau zoo ntawm lub tshuab txheej.
