Daim ntawv no qhia txog kev sim kawm txog cov lej hloov thiab kev tshawb nrhiav cov kev tshawb fawb siv rau hnub no txoj kev tshawb fawb los ntawm cov ntawv tshaj tawm cov ntawv xov xwm. Lub hom phiaj ntawm kev tshawb fawb txog kev lag luam yog nrhiav cov ntsiab lus tshiab rau qhov teeb meem hauv qhov system, kom muaj peev xwm ua tau kom muaj peev xwm ntxiv thiab ua kom muaj peev xwm ntau ntxiv hauv kev lag luam tshiab; thiab kom txuag lub sij hawm thiab cov nqi los ntawm qhov kev sib tham ntawm kev sib tham thiab kev tshawb nrhiav. Ua kom muaj kev sib koom tes ntawm kev lag luam luam tawm thiab txhim kho kev lag luam.
Tam sim no, cov kev luam ntawv zoo thiab tsim khoom tsim nyog rau qhov offset presses yuav tsum tau muaj kev tshaj siab thiab muaj kev ntseeg siab. Qhov siab tshaj plaws ntawm cov xauv npoo txheej thaum lub sij hawm luam tawm yog kwv yees li 0.05
Ntsig, los yog qhov sib txawv ntawm txoj hauj lwm ntawm cov xim sib cais duab ntawm cov duab xim, qhov siab tshaj plaws kev yuam kev ntawm ib qho xim sib cais duab los ntawm ntug ntawm lwm xim sib cais duab yog 0,02 hli, uas yog technically tau txais nyob rau hauv ib txwm txwm luam ntawv thiab sib txuas xov xwm tsis. Lub Scope.
Xws li cov kev cai no tsuas yog ua tau los ntawm cov kev tshawb fawb rau hauv kev ua lag luam rau kev ua lag luam, uas pib txhawb kev tsim khoom thiab kev tsim tawm ntawm cov ntawv xovxwm. Lub complexity ntawm tus txheej txheem luam ntawv thiab luam tawm xovxwm yuav tsum tau tshawb fawb ntau heev.
Ntxiv rau qhov kev tshawb nrhiav cov kev tshawb fawb los ntawm cov tshuab luam ntawv uas tsis yog kev tshwj xeeb rau xovxwm engineering, kuj muaj cov kev tshawb fawb tshwjxeeb los ntawm cov tshuab luam ntawv thiab cov tshuab luam ntawv tshuab luam tawm thiab ntau lub chaw tshawb fawb thoob ntiaj teb. Cov lag luam thiab cov koom haum tshawb nrhiav tau koom tes nrog kev tshawb fawb los ntawm kev tshawb fawb, kev tsim khoom thiab kev loj hlob ntxiv.
Feem ntau siv cov cuab yeej thiab cov kev siv rau cov kev tshawb fawb thiab kev tshawb nrhiav theoretical hauv cov kev tshawb fawb, nrog rau kev tsim cov cuab yeej tshiab thiab kev loj hlob ntawm cov kev tshawb fawb ntxiv. Daim ntawv no tau pib tshaj tawm cov kev tshawb nrhiav kev tshawb nrhiav ntawm number case hloov.
Tsim thiab muab xam los ntawm number case hloov cev
1. Txawv mus hloov cov qauv tsim
Cov cwj pwm hloov xees rau cov ntawv luam tawm kev xa tawm ntawm tus number case los ntawm tus cwj mem xiav rau ntawm cov ntawv xov xwm los ua ib lub plhaub nyias ntawm xaj ntawm ib qho thickness ntawm lub phaj printing. Nws yog pom meej tias tus nqi ntawm cov cwj pwm uas tau pauv yog nyob ntawm cov duab uas tau muab luam tawm, thiab tus lej ntawm tus cag tom hauv ntej yuav tsum luam tawm raws li cov duab luam. Vim li no, txoj kev tswj ntawm tus number case feem ntau yog ua los ntawm kev faib tawm. Vim yog txoj cai uas yuav tsum tau ua rau cov thickness ntawm tus number case txheej thiab cov kev tiv thaiv ntawm cov teebmeem diffusion, tus number case hloov system tsim yog ib qho nyuaj thiab nyuaj cov khoom ntawm cov ntawv xovxwm.
Txoj kev loj hlob ntawm txhua hom offset xovxwm nyob ntawm tus qauv tsim ntawm lub cuav hloov tshiab, thiab lub cwj pwm hloov lub cev yuav tsum ua raws li cov hauv qab no:
ib tug, ib co cim zoo nkaus plawg hauv txheej thiab ntev ntawm cov ntawv luam ntawv;
b, cov kev cai tswjfwm ceev, kev teb lus zoo;
c. Kev cais ntawm cov nyias nyias ntawm tus cwj pwm ntawm txhua cov xim sib cais duab me me, uas yog, tsawg rhiab heev rau cov nyom ntawm kev faib (xws li kev hloov hauv qhov kub thiab txias);
d, ntau yam kev tswj qhev rau tus nqi ntawm tus number case thiab cov dej ntub dej;
e, kev pabcuam nyiaj txiag, thiab lwm yam.
Qhov tsis rau kev tsim tus number case rau cov tub ntxhais hluas mas yog cov khoom, txoj kab nruab nrab, kev kho thiab kev txav, thiab cov xov tooj ntawm cov ink rollers. Hauv kev txhim kho cov txheej txheem ntawm txoj kev loj hlob, lub sijhawm thiab tus nqi ntawm cov cwj pwm hloov chaw, feem ntau ntawm cov mechanisms siv nyob rau hauv cov qauv tsim ntawm tus number case hloov yog raws li kev paub thiab cov kev sim. Yog li, los ntawm kev tshawb nrhiav kev siv tus lej number case hloov ntawm tus cwj pwm hloov qhov system, lub hom phiaj yog los tsim nws cov theoretical hauv paus thiab kom tsim qauv mis hloov system feem ntau. Hauv cov hnub qub, qee cov neeg tab tom nrhiav kom tau qhov kev hloov ntawm cov cwj pwm hloov.
2. Kev laij thiab kev simulation
Nyob rau hauv 1960, Mill ua ntej npaj ib txoj kev rau xam tus thickness ntawm tus number case txheej hauv ib qho kev hloov number case. Ib qho kev sib npaug ntawm tus nqi yog tsim los rau tus lej ntawm tus lej ntawm ib qho zauv uas muaj feem thib ob, uas ua rau lub cev sib haum. Nyob rau hauv no system, lub thickness ntawm tus number case txheej tsis paub. Ruder tau npaj ib txoj kev ncaj thiab yooj yim rau txoj kev txiav txim siab ntawm cov inkness txheej rau cov duab ntawm cov kabmob uas tsis hloov hauv cov cwj mem kua hloov.
Nyob rau hauv ob lub tswv yim ntawm Ruder, tsuas yog nruab nrab number case layer thickness tau suav. Nws tsis muaj peev xwm los laij tus inclination ntawm lub thickness ntawm tus number case txheej nyob rau hauv cov kev coj ntawm txoj kab ntawm tus number case roller thiab cov ntawv phaj. Hauv xyoo 1971, qhov teeb meem no yog thawj zaug tau thov los ntawm Rech thiab daws nrog kev pab ntawm lub computer.
Rau qhov kev qhia no raws li txoj kev ua kom lub kaum sab xis, tag nrho cov cwj pwm dauv thiab lub circumference ntawm lub nruas raug faib rau hauv seem ntawm tus loj tib yam. Lub thickness ntawm tus number case txheej ntawm txhua lub xoom npoo tawm yog tsim los ntawm kev tsim ib qho kev ua zauv thiab daws cov kab zauv. Raws li qhov kev siv algorithm, ib qho ntxiv kev muab tswvyim yog tswvcuab, uas yuav siv rau tus lej ntawm ntau thiab ntau tus lej hloov tshuab, yog li ntawd nws yuav tsum tau zoo kwv yees qhov tseeb thickness ntawm tus number case txheej. Hauv txoj kev xam kev nrhiav thiab simulating ze rau qhov xwm txheej li qhov ua tau, nws yog qhov tseem ceeb heev los txiav txim qhov kev ua raws cai, legitimacy thiab number case parameters.
Tshaj tawm los ntawm Patzelt thiab Ruder nyob rau hauv qhov kev tshawb fawb FGD, NKTEAM simulation program qhia txog cov kev tshwm sim tshiab hauv technology. Nws tsuas yog xam cov hauv qab no tsis:
a, qhov geometric tsis muaj cwj pwm hloov qhov system; b. Nruam lossis muab ntu nruab nrab ntawm tus cwj mem; c, number case thauj hauv qhov ncig thiab cov lus taw qhia; d, txhawm rau cov dej ntws thiab cov evaporation; e, kub; f. tom qab faib; g, kua cug quav.
Lub kaw lus INKTEAM number transfer yog qhov system analog. Thaum pib, tus number case hloov ntawm daim ntawv yog khoob, tus number case yog sib cais, tus number case yog pauv thoob hauv lub cwj pwm hloov qhov system, thiab txhua txhua simulation xam qhov kev lag luam recalculates lub tshuab luam ntawv kom txog thaum lub thickness ntawm tus number case txheej nyob rau hauv ib sab ntawm daim ntawv luam tsis hloov, uas yog, txog Achieve ruaj khov mob. Nws tuaj yeem pom los ntawm cov lej ntawm xam tus txheej txheem uas nws tau kuaj los ntawm ob tug lej hloov tshuab hauv cov lus qhia ntev.
Hauv thawj cov ntaub ntawv, txhua daim ntawv ntiv xo thiab cov thooj dej dej nyob hauv kev sib txuas nrog phaj lub tog raj kheej, thiab qhov sib nkag ntawm simulation thiab qhov kev xeem tsis zoo txaus siab. Qhov no tuaj yeem raug vim rau kev sib cuam tshuam ntawm ntau ntawm cov kev xam thiab qhov tseeb ntawm lawv qhov chaw. Tsuas hloov qhov feem pua ntawm cov feem pua ntawm cov xwm txheej uas muaj feem cuam tshuam txog kev muab cais tawm ua rau nyias txawv nyias.
Nyob rau hauv rooj plaub thib ob, tus cwj mem thiab cov kua xiav yog ib txav mus rau cov phom ntawm lub voos kheej kheej los ntawm cov kab ntub, thiab qhov zoo tuaj yeem tsim tau, uas yog, peb muaj cov lej khov khov, thiab qhov khaus thiab khov lub hau dhau los ntawm. Ib tug choj ntawm tus neeg ntxeem rau kev thauj tus number case.
