Cov hauv paus thiab cov txiaj ntsig ntawm cov hlau 3D tshuab luam ntawv
Cov tswv yim tseem ceeb tom qab hlau 3D luam tawm, tseem hu ua kev tsim khoom ntxiv, yog los tsim peb- qhov seem ntawm cov khoom siv hlau ntawm ib sab. Qee cov qauv hlau 3D nquag muaj xws li cov qauv hlau 3D muaj xws li xaiv laser melting (SLM) thiab hluav taws xob ci melting (EBM). Cov thev naus laus zis siv siab heev - lub zog ci teeb, zoo li lasers lossis hluav taws xob ci, kom yaj thiab tawv thiab tawv tawv hlau ib txheej ib zaug. Qhov no tsim cov khoom nrog cov qauv sib txawv thiab cov qauv.
Hlau 3D Luam Ntawv muaj txiaj ntsig ntau dhau los dhau txoj kev tsim khoom. Ua ntej, nws tuaj yeem pwm cov txheej txheem nyuaj txhua lub sijhawm tsis muaj muab tso ua ke ntau qhov chaw. Qhov kev txiav tawm no nyob ntawm tus naj npawb ntawm cov pob hluav taws xob tsis muaj zog hauv kev sib txuas thaj chaw thiab ua rau cov khoom siv muaj zog dua thiab muaj zog dua txhua yam. Qhov thib ob, kev luam ntawv yog tswj tau cov ntaub ntawv kom raug raws li cov khoom siv tsim qauv, thiab siv cov khoom tsawg dua thiab qhov hnyav thaum cov cuab yeej ua haujlwm. Cov txheej txheem no tseem tuaj yeem nrawm ua cov protypes thiab me me ntawm qhov chaw, uas nrawm cov txheej txheem ntawm kev ua cov khoom lag luam tshiab thiab cov nqi qis dua.
Lub tswv yim yog kom ua cov cuab yeej siv tau zoo dua nyob nrog nrog kev kub heev.
Ua rau microstructure ntawm cov khoom zoo dua
Thaum koj 3D luam tawm hlau, lub siab- Lub zog nqaj loj hlob sai me me thiab solidifies hlau hmoov. Qhov no tshwm sim tau sai dua sai dua li hauv cov txheej txheem tsoosting. Qhov txheej txheem cua txias no tuaj yeem ua rau cov hlau cov nplej loj me me thiab tsim microstructous thiab zoo microstructivure. Cov nplej me me tuaj yeem tso tseg cov khoom siv rho tawm, ua cov khoom muaj zog thiab nyuaj dua, thiab ua cov khoom siv zoo dua tuaj yeem tiv thaiv tsis taus hauv qhov siab- tej kev mob kub. Kev Solm Solidation ceev tseem tuaj yeem tsim qee cov qauv theem tshwj xeeb, suav nrog nanoscale precipitates, uas tuaj yeem nyob ruaj khov ntawm qhov kub thiab ua kom cov khoom muaj zog dua.
Ua kom txias raws qhov uas tsis nkag siab
Ib qho kev ua kom txias txias yog qhov tseem ceeb tshaj plaws rau cov khoom siv hluav taws xob txij li thaum nws txo qis qhov kub ntawm cov khoom siv thiab ua rau nws muaj peev xwm kov tau kub. Hlau 3D luam ntawv ua rau nws yooj yim kom ua cov ntawv nrog kev sib cuam tshuam sab hauv txias raws. Nws muaj peev xwm txhim kho thiab tsim cov kab cua txias no raws li cas cov thermal load no tau tshaj tawm cov khoom siv. Qhov no yuav ua rau cov nyhuv txias kom ntau thiab siv tau. Piv txwv li, 3D luam tawm yog siv los ua kom muaj roj turbine hniav nrog cov teeb tsa sab hauv kab noj hniav. Cov nta tau pab kom loj hlob cua txias cua hla ntawm saum npoo ntawm cov hniav, txo lawv lub neej ua haujlwm, thiab ntev lawv lub neej.
Tus qauv rau kev ua kom zoo tshaj plaws
Topology Optimization yog ib txoj hauv kev los ua qauv qauv siv cov algorithms. Nws tuaj yeem txiav txim siab txoj kev zoo tshaj plaws rau cov khoom xa tuaj rau hauv qhov chaw tsim kom zoo kom lawv sib phim qee yam kev ua tau zoo. Los ntawm kev siv ob qho tib si hlau 3D tshuab luam ntawv thiab kev txhim kho kom zoo dua, koj tuaj yeem ua rau ib qho {{{{{4 5}} zoo} Cov qauv zoo. Cov qauv no tuaj yeem pab cov cuab yeej siv zog muaj zog thaum ua kom qhov hnyav thiab yog qhov zoo ntawm kev tshem tawm thaum tshav kub. Piv txwv li, thaum tsim cov qauv cua sov, cov qauv tshiab ua nrog cov tshuab txhim kho kom zoo dua qub, ua rau cov cua sov sib pauv ntau dua, thiab qis dua cov khoom siv ua haujlwm kub.
Tau 3D tau luam ntawv nrog hlau ua cov khoom hauv cov khoom siv zog ua haujlwm ua ke?
Qhov teeb meem ntawm seb cov khoom siv hluav taws xob ib txwm muaj zog yuav ua haujlwm ua ke
Vim tias kev tsim qauv kev txwv, lub interface tsis kab.
Feem ntau cov txheej txheem tsim khoom lag luam txwv tsis pub muaj cov cuab yeej siv hluav taws xob ib txwm tuaj yeem tsim. Piv txwv li, hauv cov khoom siv roj tawm, cov sib txawv ntawm cov cuab yeej drilling zoo kawg nkaus, tab sis kev ua kom muaj teeb meem ua ke ntawm cov sib txawv ntawm cov sib txawv kom haum. Qhov no yuav ua teeb meem nrog cov kab mob loj lossis dhau ntawm cov khoom siv ua ke, uas yuav cuam tshuam zoo li cas nws, thiab thaum kawg, nws yuav ua rau cov khoom siv tsis txhim khu kev qha thiab tsawg dua.
Cov ntaub ntawv sib txawv ua rau ua tau zoo kom tsis raug cai.
Cov ntaub ntawv siv rau cov khoom siv hluav taws xob sib txawv yuav muaj ntau yam cuam tshuam thermal kev nthuav tawm coefficients, hardness, lub zog, thiab lwm yam zoo. Thaum ua haujlwm nrog kev sib txuas ntawm cov ntaub ntawv sib txawv, cov qauv kev ua yeeb yam feem ntau muaj teeb meem ua teeb meem kom cov ntsiab lus sib txuas yog muaj zog thiab ruaj khov. Hauv cov khoom siv hluav taws xob nuclear lub zog, piv txwv, qee qhov tseem ceeb yuav tsum muaj peev xwm daws teeb meem thiab hluav taws xob. Thaum muaj ntau cov ntaub ntawv tau muab tso ua ke nrog cov kev mob kub, siab siab, thiab hluav taws xob, lawv yuav tsis ua haujlwm ua ke zoo li lawv yuav tsum tau ua. Qhov no tuaj yeem ua cov teeb meem xws li thermal ntxhov siab thiab kev sib txuas tsis ua haujlwm, uas tuaj yeem ua rau cov khoom siv tsawg dua thiab sib xws.
Nws yog qhov nyuaj rau kev hloov kho kev hloov kho.
Raws li lub zog hluav taws xob khaws cov loj hlob, ntau thiab ntau tus neeg siv khoom thov kom cov khoom siv hluav taws xob uas ua tau raws lawv cov kev xav tau tshwj xeeb. Vim hais tias ntawm cov kev txwv ntawm cov nplai ntau lawm, cov txheej txheem kev tsim khoom lag luam yog kim thiab siv sijhawm ntev los ua cov khoom me me thiab cov chaw ua haujlwm me me. Qhov no ua rau nws nyuaj rau cov neeg siv hluav taws xob kom nrawm tau raws li cov kev xav tau ntawm cov neeg siv khoom uas xav tau qee yam. Raws li qhov tshwm sim, qhov chaw ntawm cov khoom sib txawv tsis ua haujlwm zoo ua ke, uas ua rau cov nuj nqis ntawm kev tswj hwm thiab txhim kho cov cuab yeej.
Cov hauv paus thiab cov txiaj ntsig ntawm cov hlau 3D luam rau kev ua cov khoom ua haujlwm zoo dua ua ke
Kev tsim qauv yog kom tau txais qhov zoo tshaj plaws interface
Khoos phib tawj {-} Txoj kev tsim qauv (CAD) yog siv rau hauv cov khoom siv hlau 3D tshuab los ua qhov tseeb nrog qhov tseeb. Cov neeg tsim qauv yuav yog qhov loj me, qauv, thiab cov qauv sib xyaw ua ke nrog cov khoom siv sab hauv, ua kom paub tseeb tias qhov sib txawv ntawm cov muaj kev sib txawv. Piv txwv li, thaum ua gearboxes rau cua tshuab, tshuab luam ntawv hlau tuaj yeem ua rau cov mating ua kom cov kais dej thiab cov khoom siv qis, txhawb kev kis tau zoo, thiab ua cov khoom siv ntau ntxiv.
Nrhiav cov khoom sib xyaw zoo tshaj plaws los txhim kho kev ua kom sib haum
Cov cuab yeej siv tshuab hlau 3D tau luam tawm nrog ntau yam hlau thiab ua qhov chaw nrog cov khoom muaj ntau yam uas muaj kev faib tawm gradient. Nws muaj peev xwm tau txais cov kev ua tau zoo tshaj plaws ntawm cov ntaub ntawv los ntawm kev ua tib zoo xaiv thiab sib xyaw ua kom tau raws li cov kev xav tau ntawm cov cheebtsam thiab cov xwm txheej uas lawv yuav siv. Piv txwv li, thaum ua cov roj turbine tawg, koj tuaj yeem ua haujlwm siab- lub zog alloy cov ntaub ntawv ntawm lub hauv paus ntawm cov hniav los ua kom lawv nyob sib txuas. Txhawm rau ua kom cov hniav tiv thaiv ntau dua tiv taus cua sov thiab xeb, kho lawv cov chaw uas muaj cov sib xyaw uas tuaj yeem tiv taus ntau qhov kub thiab xeb. Cov qauv no ntawm kev txhim kho cov khoom siv tuaj yeem ua cov khoom sib xyaw ua haujlwm tau ua haujlwm zoo dua ua ke thiab ua cov khoom siv tau txhim khu kev qha.
Customization uas yog nrawm thiab yooj yim kom phim cov kev xav tau sib txawv
3D luam ntawv nrog hlau yog zoo rau kev ua cov khoom me me ntawm cov khoom sib txawv. Cov tuam txhab tsim khoom tuaj yeem nrawm ua qhov chaw uas yog cov neeg siv khoom xav tau. Nws txiav cia rau lub sijhawm ntau lawm thiab cov nqi ntau yam tsis tas yuav tsum tau nqis peev rau cov kab thiab cov kab ntau lawm. Qhov no yuav pab cov khoom siv hluav taws xob zoo dua kom txaus siab rau lawv cov neeg siv khoom thiab ua haujlwm zoo dua nrog cov khoom siv ntau yam. Piv txwv li, nyob hauv thaj teb ntawm Hnub ci photovoltaics, cov chaw sib txawv yuav muaj kev teeb tsa sib txawv thiab cov neeg siv khoom yuav muaj sib txawv, thiab cov khoom siv, thiab txoj kev uas photovoltaiic tau ntsia. Siv cov tshuab ntaus hlau 3D tshuab, cov hnub ci ci ntsa iab uas haum rau kev siv tau hauv zos yuav ua tau ceev, ua kom haum rau nruab thiab ntau dua nrog lwm cov tshuab.
