Qhov kev ntseeg siab ntawm kev ua haujlwm ntawm cov tshuab nyuaj - los ntawm cov txheej txheem txhawb nqa hydraulic mus rau cov cuab yeej lithography siab heev - yog qhov tseem ceeb nyob ntawm nws cov qauv tsim kho (tsis yog tus qauv). Thaum cov hauv paus no tsis ua haujlwm lossis tsis zoo, cov txheej txheem kho thiab hloov pauv tsim nyog yuav tsum ua tib zoo sib npaug ntawm cov qauv, cov khoom siv, thiab cov kev xav tau ntawm daim ntawv thov. Lub tswv yim txij nkawm rau cov khoom tsis yog tus qauv yuav tsum tig ib puag ncig kev ntsuam xyuas hom kev puas tsuaj, kev faib tawm kev ntxhov siab, thiab kev ua tiav ntawm kev ua haujlwm, thaum kev hloov pauv xav tau kev ua raws li kev lees paub sib xws thiab cov txheej txheem calibration dynamic.
I. Kev puas tsuaj thiab cov tswv yim kho kom raug
Kev puas tsuaj rau cov hauv paus kev cai feem ntau yog qhov tawg hauv zos, kev ua tsis tiav ntawm cov ntsiab lus sib txuas, lossis kev cuam tshuam geometric ntau dhau. Ib qho kev ua tsis tiav hauv lub hauv paus txhawb nqa hydraulic, piv txwv li, yog qhov tawg ntawm cov khoom siv khov kho tseem ceeb, uas xav tau txoj hauv kev kho sib txawv heev. Yog tias qhov tawg tshwm sim ntawm qhov chaw sib txuas, feem ntau yog los ntawm kev qaug zog los ntawm kev ntxhov siab cyclic, kev kho yuav tsum tau tshem tawm cov phaj npog, tom qab ntawd kev txhawb nqa nrog cov hlau niam txiv-hlau sib phim, thiab kev vuam groove kom zoo kom rov qab ua kom sib txuas ntawm cov tav tseem ceeb. Qhov no feem ntau ua raws li sleeving los faib thiab sib npaug cov zog thauj khoom.
Hauv thaj chaw ntawm cov khoom siv siab heev, kev kho mob tsom mus rau kev txo qhov kev puas tsuaj me me. Xav txog lub hauv paus ntawm cov cuab yeej siv kho qhov muag uas muaj qhov tawg me me ntawm qhov chaw vim yog kev co ntev. Kev kho yuav siv cov thev naus laus zis laser cladding los tso cov hmoov hlau sib xyaw ua ke raws li cov khoom sib xyaw ntawm cov khoom siv. Cov txheej txheem no tso cai rau kev tswj hwm qhov tuab ntawm cov txheej cladding kom raug, ua tiav kev kho tsis muaj kev ntxhov siab uas zam qhov chaw cuam tshuam los ntawm cua sov thiab kev puas tsuaj ntawm cov khoom siv uas cuam tshuam nrog kev vuam ib txwm muaj. Rau cov khawb ntawm qhov chaw uas tsis muaj kev thauj khoom, cov txheej txheem Abrasive Flow Machining (AFM), siv cov khoom siv abrasive semi-solid, tuaj yeem hloov kho rau cov duab sib txawv, tshem tawm cov qhov tsis zoo ntawm qhov chaw thaum tseem khaws cia cov qauv geometric qub.
II. Kev lees paub thiab Kev Tswj Xyuas Kev Sib Haum rau Kev Hloov Chaw
Kev hloov lub hauv paus tshwj xeeb yuav tsum muaj lub kaw lus 3D lees paub uas suav nrog kev sib xws ntawm geometric, kev sib phim cov khoom siv, thiab kev ua haujlwm zoo. Piv txwv li, hauv qhov project hloov lub hauv paus cuab yeej CNC, tus qauv tshiab tau koom ua ke rau hauv lub tshuab qub Finite Element Analysis (FEA) tus qauv. Los ntawm kev ua kom zoo dua topological, qhov kev faib tawm ntawm cov khoom tshiab tau sib phim zoo rau qhov qub. Qhov tseem ceeb, 0.1 hli elastic compensation txheej yuav raug koom ua ke rau hauv cov nplaim sib cuag kom nqus tau lub zog co ntawm kev ua haujlwm. Ua ntej kev teeb tsa zaum kawg, lub laser tracker ua qhov sib phim qhov chaw, kom ntseeg tau tias kev sib luag ntawm lub hauv paus tshiab thiab lub tshuab cov lus qhia tau tswj hwm hauv 0.02 hli kom tiv thaiv kev txav mus los vim yog kev teeb tsa tsis raug.
Qhov sib xws ntawm cov khoom siv yog qhov tseem ceeb uas tsis tuaj yeem sib tham tau ntawm kev lees paub qhov hloov pauv. Thaum hloov lub platform txhawb nqa tshwj xeeb hauv hiav txwv, cov khoom tshiab yog ua los ntawm cov hlau duplex stainless hlau zoo sib xws. Kev sim tshuaj xeb electrochemical kom paub tseeb tias qhov sib txawv me me ntawm cov khoom tshiab thiab cov khoom qub, xyuas kom meej tias tsis muaj kev xeb galvanic sai dua hauv qhov chaw dej hiav txwv hnyav. Rau cov hauv paus sib xyaw, kev sim sib phim coefficient thermal expansion yog qhov yuav tsum tau ua kom tiv thaiv kev sib cais ntawm cov interfacial los ntawm kev hloov pauv kub.
III. Kev Kho Kom Zoo Dua thiab Kev Hloov Kho Dua Tshiab
Tom qab hloov pauv, kev kho kom zoo tag nrho yog qhov tseem ceeb kom rov qab tau qhov kev ua tau zoo qub ntawm cov khoom siv. Ib qho piv txwv zoo yog kev hloov pauv ntawm lub hauv paus tshuab semiconductor lithography. Tom qab kev teeb tsa, lub laser interferometer ua qhov kev sim dynamic ntawm qhov tseeb ntawm kev txav mus los ntawm lub rooj ua haujlwm. Los ntawm kev kho kom raug ntawm lub hauv paus sab hauv piezoelectric ceramic micro-adjusters, qhov yuam kev rov ua dua qhov chaw tuaj yeem kho tau los ntawm qhov pib 0.5 μm mus rau tsawg dua 0.1 μm. Rau cov hauv paus kev cai txhawb nqa cov khoom thauj tig, kev tshuaj xyuas modal raug ua, feem ntau xav tau kev ntxiv cov qhov damping lossis kev faib tawm pawg kom hloov cov khoom ntawm qhov zaus resonant ntuj ntawm qhov system qhov kev ua haujlwm, yog li tiv thaiv kev co overruns.
Kev hloov kho dua tshiab ntawm lub luag haujlwm yog ib qho kev txuas ntxiv ntawm cov txheej txheem hloov pauv. Thaum txhim kho lub hauv paus ntawm lub rooj zaum kuaj lub cav aerospace, cov qauv tshiab yuav raug koom ua ke nrog lub network wireless strain gauge sensor. Lub network no saib xyuas kev faib tawm ntawm txhua qhov chaw bearing hauv lub sijhawm tiag tiag. Cov ntaub ntawv raug ua tiav los ntawm lub module xam ntug thiab pub ncaj qha rov qab mus rau lub kaw lus tswj hwm, uas tso cai rau kev hloov kho dynamic ntawm cov kev ntsuas kev xeem. Qhov kev hloov kho ntse no tsis yog tsuas yog rov qab kho dua tab sis txhim kho cov khoom siv kev xeem kev ncaj ncees thiab kev ua haujlwm zoo.
IV. Kev Txij Nkawm Ua Ntej thiab Kev Tswj Xyuas Lub Neej
Cov tswv yim kev pabcuam thiab kev hloov pauv rau cov hauv paus tshwj xeeb yuav tsum tau muab tso rau hauv cov qauv kev saib xyuas ua ntej. Rau cov hauv paus uas raug rau cov chaw muaj xeb, kev sim ultrasonic non-destructive (NDT) txhua peb lub hlis yog qhov pom zoo, tsom mus rau cov vuam thiab thaj chaw muaj kev ntxhov siab. Rau cov hauv paus uas txhawb nqa cov tshuab vibrating siab zaus, kev tshuaj xyuas txhua hli ntawm cov khoom siv fastener pre-tension los ntawm txoj kev torque-angle ua kom muaj kev sib txuas zoo. Los ntawm kev tsim cov qauv kev puas tsuaj raws li cov nqi tawg, cov neeg ua haujlwm tuaj yeem kwv yees qhov tseeb ntawm lub hauv paus lub neej siv tau, tso cai rau kev ua kom zoo tshaj plaws ntawm cov voj voog hloov pauv - piv txwv li, txuas ntxiv lub hauv paus hloov pauv gearbox los ntawm tsib xyoos mus rau xya xyoos, txo cov nqi kho tag nrho.
Kev saib xyuas cov chaw tsim khoom tshwj xeeb tau hloov zuj zus los ntawm kev teb tsis siv neeg mus rau kev cuam tshuam ntse. Los ntawm kev sib koom ua ke cov thev naus laus zis tsim khoom siab heev, kev paub ntse, thiab cov peev xwm digital twin, lub ecosystem saib xyuas yav tom ntej rau cov qauv tsis yog tus qauv yuav ua tiav kev kuaj mob tus kheej ntawm kev puas tsuaj, kev txiav txim siab kho tus kheej, thiab kev teem sijhawm hloov pauv zoo tshaj plaws, lav qhov kev ua haujlwm ruaj khov ntawm cov khoom siv nyuaj thoob ntiaj teb.
