Nyob rau hauv cov txheej txheem ntawm cov roj teeb lithium-ion, txheej txheej txheej, raws li qhov txuas tseem ceeb, cuam tshuam ncaj qha rau kev ua haujlwm thiab kev nyab xeeb ntawm cov roj teeb. Kev ruaj ntseg ntawm lub zog tswj platform ntawm lithium roj teeb txheej tshuab plays lub luag haujlwm txiav txim siab hauv qhov tseeb txheej. Granite thiab cam khwb cia hlau, raws li feem ntau siv platform cov ntaub ntawv, qhov sib txawv ntawm lawv qhov seem stability tau nyiam ntau xim. Tsab ntawv xov xwm no yuav tshawb xyuas qhov kev txhim kho tseem ceeb hauv kev ruaj ntseg ntawm granite piv rau cam khwb cia hlau ntawm lub zog tswj platform ntawm lithium roj teeb txheej tshuab los ntawm cov khoom siv, cov ntaub ntawv sim thiab cov ntaub ntawv siv tau. cov
Cov khoom siv txiav txim siab lub hauv paus ntawm kev ruaj ntseg
Cam khwb cia hlau, raws li ib txwm muaj cov khoom siv, yog ib zaug siv dav hauv kev tswj kev txav chaw vim nws qhov kev ua tau zoo casting zoo thiab tus nqi zoo. Txawm li cas los xij, cov khoom siv hlau cam khwb cia muaj qhov tsis xws luag. Nws cov qauv sab hauv muaj ntau ntawm flake graphite, uas yog sib npaug rau cov kab nrib pleb sab hauv thiab yuav txo tau tag nrho cov rigidity ntawm cov khoom. Lub caij no, cov coefficient ntawm thermal expansion ntawm cam khwb cia hlau yog qhov siab, kwv yees li 10-12 × 10⁻⁶ / ℃. Nyob rau hauv lub tsub zuj zuj ntawm tshav kub generated los ntawm lub sij hawm ntev lub sij hawm ua hauj lwm ntawm lithium roj teeb txheej, nws yog nquag thermal deformation. Tsis tas li ntawd, muaj kev nyuaj siab casting hauv cam khwb cia hlau. Sij hawm dhau mus, qhov kev tso tawm ntawm kev ntxhov siab yuav ua rau tsis muaj kev hloov pauv hauv lub platform loj, cuam tshuam rau qhov tseeb ntawm txheej txheej. cov
Granite yog cov khoom siv ntuj tsim los ntawm cov txheej txheem geological ntau pua lab xyoo. Nws cov qauv siv lead ua sab hauv yog tuab thiab sib xws, thiab nws muaj qhov ruaj khov siab. Lub linear expansion coefficient ntawm granite tsuas yog 0.5-8 × 10⁻⁶ / ℃, uas yog 1/2-1/3 ntawm cov hlau cam khwb cia, thiab nws yog qhov tsis hnov tsw rau qhov kub thiab txias. Lub caij no, granite yog ib qho nyuaj hauv kev ntxhib los mos, nrog lub zog compressive siab li 1,050-14,000 kilograms ib square centimeter. Nws tuaj yeem tiv thaiv kev cuam tshuam sab nraud thiab kev co, muab lub hauv paus ruaj khov thiab ruaj khov rau lub platform tswj kev txav. Yuav luag tsis muaj kev ntxhov siab nyob hauv nws, thiab nws yuav tsis ua rau muaj kev hloov pauv vim muaj kev ntxhov siab tso tawm, ua kom muaj kev ruaj ntseg ntawm lub platform los ntawm cov ntsiab lus ntawm cov khoom. cov
Kev sim cov ntaub ntawv txheeb xyuas qhov sib txawv ntawm kev ua haujlwm
Txhawm rau pom qhov sib txawv ntawm qhov sib txawv ntawm qhov ruaj khov ntawm granite thiab cam khwb cia hlau, pab pawg tshawb fawb tau ua ib qho kev sim tshwj xeeb. Ob lub zog tswj platforms ntawm lithium roj teeb txheej tshuab ntawm tib lub ntsiab lus raug xaiv, ua los ntawm granite thiab cam khwb cia hlau feem, thiab sim nyob rau hauv tib qho kev mob ib puag ncig. Qhov kev sim simulated qhov tseeb ua haujlwm scenario ntawm lithium roj teeb txheej tshuab. Los ntawm kev ua haujlwm tsis tu ncua ntawm cov cuab yeej, qhov hloov pauv loj ntawm lub platform ntawm lub sijhawm sib txawv cov ntsiab lus tau saib xyuas. cov
Cov txiaj ntsig ntawm kev sim qhia tau hais tias tom qab ua haujlwm tas li rau 24 teev, vim qhov kub ntawm cov khoom siv ua haujlwm, qhov kub ntawm cov khoom siv hlau cam khwb cia tau nce los ntawm kwv yees li 15 ℃, uas ua rau qhov nce ntawm 0.03 hli nyob rau hauv qhov ntev kev taw qhia qhov ntev ntawm lub platform. Raws li cov xwm txheej qub, qhov hloov pauv loj ntawm granite platform yuav luag tsis pom zoo, thiab nws qhov hloov pauv loj yog tsawg dua 0.005mm. Tom qab 1000 teev ntawm kev ntsuam xyuas kev laus mus sij hawm ntev, vim qhov kev tso tawm ntawm kev ntxhov siab sab hauv thiab kev sib txuam ntawm thermal deformation, qhov kev ua yuam kev flatness ntawm lub cam khwb cia hlau platform nthuav tawm los ntawm thawj 0.01mm mus rau 0.05mm. Qhov kev ua yuam kev flatness ntawm granite platform yog ib txwm khaws cia nyob rau hauv 0.015mm, thiab qhov zoo ntawm qhov seem stability yog pom tseeb. cov
Cov txiaj ntsig zoo kawg nkaus hauv kev siv tswv yim
Nyob rau hauv qhov tseeb zus tau tej cov lithium roj teeb loj manufacturing enterprise, cam khwb cia hlau motion tswj platforms tau siv ib zaug. Raws li lub sijhawm ua haujlwm ntawm cov khoom siv tau nce, cov txheej txheej raug maj mam poob qis, ua rau cov txheej txheem tsis sib xws, tsis zoo sib xws ntawm cov roj teeb electrode nplooj ntawv, thiab cov khoom siv tsis raug siab li 8%. Yuav kom daws tau qhov teeb meem no, lub tuam txhab tau hloov cov lus tsa suab tswj platforms ntawm qee cov khoom siv nrog cov ntaub ntawv granite. cov
Tom qab hloov pauv, qhov kev ruaj ntseg ntawm cov khoom siv tau zoo dua qub. Thaum lub sij hawm rau lub hlis ntau lawm, lub txheej tshuab siv lub granite platform ib txwm khaws cov txheej thickness yuam kev nyob rau hauv ± 2μm, thiab cov khoom puas tau txo qis rau tsawg dua 3%. Meanwhile, raws li granite platforms tsis xav tau raws li nquag precision calibration thiab txij nkawm raws li cam khwb cia hlau platforms, lawv txuag cov lag luam ib tug tseem ceeb npaum li cas ntawm cov khoom siv tu nqi thiab downtime txhua txhua xyoo, thiab nce ntau lawm efficiency ntau tshaj 15%. cov
Nyob rau hauv xaus, nyob rau hauv daim ntawv thov ntawm lub suab tswj platform ntawm lithium roj teeb txheej tshuab, granite, nrog nws cov khoom zoo heev, ho outperforms cam khwb cia hlau nyob rau hauv cov nqe lus ntawm seem stability. Txawm hais tias los ntawm qhov kev xav ntawm cov khoom siv, cov ntaub ntawv sim, lossis cov txiaj ntsig ntawm daim ntawv thov, granite muab kev lees paub zoo rau kev ua haujlwm siab thiab ruaj khov ntawm lithium roj teeb txheej txheej txheem. Nrog rau kev txhim kho txuas ntxiv ntawm cov khoom lag luam zoo hauv kev lag luam roj teeb lithium, lub zog tswj platforms ua los ntawm granite yog khi los ua qhov kev xaiv tseem ceeb hauv kev lag luam.
