Siv cov cuab yeej ntawm 3D Spark software, pab pawg tau tshuaj xyuas ntau yam uas cuam tshuam rau cov nqi tsim khoom.Ib txhia ntawm lawv yog tshwj xeeb rau qhov chaw, thaum lwm tus yog tshwj xeeb rau cov txheej txheem.Piv txwv li, qhov chaw taw qhia kom txo qis kev txhawb nqa thiab ua kom cov khoom tsim tau zoo tshaj plaws.
Los ntawm kev simulating quab yuam ntawm lub pob khawm, cov cuab yeej no tuaj yeem tshem tawm cov khoom uas tsis tshua muaj txiaj ntsig.Qhov no ua rau 35% poob phaus.Cov khoom siv tsawg kuj txhais tau tias lub sij hawm luam tawm sai dua, txo cov nqi ntxiv.
Ua kom ncaj ncees, qhov lawv tab tom ua yuav tsum tsis yog tshiab rau ib tus neeg koom nrog hauv 3D luam ntawv.Nws ua rau kev txiav txim siab npaj ib feem ntawm txoj kev tsim nyog.Peb tau pom cov khoom pov tseg tshem tawm hauv 3D luam ntawv thiab kev tsim khoom ib txwm muaj.Qhov nthuav tshaj plaws yog siv cov cuab yeej uas pab automate no optimization.Peb tsis paub ntau npaum li cas cov software yuav raug nqi, thiab peb tab tom kwv yees nws tsis yog tsom rau kev ua lag luam 3D luam ntawv hobbyist.Tab sis xav paub dab tsi tuaj yeem ua tau, peb xav tias nrog qee lub hauv caug lubrication thiab ua qauv hauv software muaj, koj tuaj yeem tau txais cov txiaj ntsig zoo sib xws.
Hauv txoj kev xav, txhua lub cuab yeej uas tuaj yeem ua tiav qhov kev txheeb xyuas qhov kawg yuav tsum tuaj yeem txiav txim siab cov khoom yuav raug tshem tawm.Peb tau pom tias automakers siv 3D luam ntawv.
"Los ntawm kev simulating rog ntawm pob khawm, cov cuab yeej no tuaj yeem tshem tawm cov khoom uas tsis muaj kev cuam tshuam loj.Kuv tsis yog engineer, tab sis kuv nyeem qhov no thiab xav Finite Element Analysis.Tom qab ntawd kuv pom koj hauv kab lus kawg.Hais txog nws .Tau kawg automakers twb ua.Peb puas muab piv li cas?Cov qauv no puas muab kev quab yuam thaum muaj xwm txheej ceev nrog rau kev siv ib txwm?
Txhua ntug, hav thiab fillet yuav tsum tau siv lub sij hawm tshuab thiab cov cuab yeej siv.Qee qhov kev hloov cuab yeej ntxiv yuav xav tau, thiab thaum ua haujlwm ntawm qhov sib txawv, cov khoom yuav tsum tau muab tshuab thiab rov txuas ntxiv kom coj mus rau hauv kev taw qhia uas tuaj yeem ua rau ntau lub hnab ris - yog tias lawv tuaj yeem muaj cov cuab yeej tsim nyog nyob ib puag ncig.
Kuv xav tias koj tuaj yeem siv lub tshuab nrog ntau qib ntawm kev ywj pheej los tig rau lub kaum sab xis zoo tshaj plaws… Tab sis tus nqi dab tsi?
3D luam ntawv feem ntau tsis muaj cov kev txwv zoo li no, ua qhov nyuaj ua kom yooj yim raws li qhov yooj yim.
Ntawm qhov tod tes, qhov kom zoo dua ntawm cov tsoos subtractive machining yog tias cov khoom siv zoo li isotropic, nws muaj zog sib npaug ntawm txhua qhov kev taw qhia, thiab tsis muaj cov flats sab hauv, koj tsis tas yuav txhawj xeeb txog kev sib txuas tsis zoo vim qhov phem sintering.Nws kuj tseem tuaj yeem mus dhau ntawm lub tshuab dov (ib kauj ruam pheej yig) kom muab cov qauv nplej zoo.
Txhua txoj kev luam ntawv 3D muaj qhov txwv tsis pub muaj.Txawm ib feem ntawm SLM.Raws li koj tuaj yeem xav, qhov xwm txheej isotropic ntawm SLM tsis muaj teeb meem tiag tiag.Cov tshuab thiab cov txheej txheem siv niaj hnub muab cov txiaj ntsig zoo ib yam.
Txawm li cas los xij, pricing nws tus kheej yog lwm yam tsiaj nyaum.Hauv kev lag luam aerospace, 3D luam ntawv yog ib qho nyuaj rau kev sib tw tiag tiag.
Kuv xav hais tias kev lag luam aerospace yog ib qho ntawm ob peb qhov chaw uas tus nqi ntawm cov hlau 3D luam ntawv tuaj yeem ua ncaj ncees.Tus nqi pib tsim khoom yog ib feem me me ntawm tus nqi ntawm cov khoom siv dav hlau, thiab qhov hnyav yog qhov tseem ceeb heev uas nws yooj yim nrhiav kev siv rau nws.Piv nrog rau cov nqi saum ntuj-siab ntawm kev lees paub zoo rau cov khoom sib xyaw, cov txheej txheem luam ntawv txawj thiab kev tshuaj xyuas qhov tseem ceeb tuaj yeem muab kev txuag nqi tiag tiag thiab ua pa ntawm huab cua ntshiab.
Cov piv txwv pom tseeb tshaj plaws yog txhua yam uas tau luam tawm hauv cov tshuab foob pob hluav taws niaj hnub no.Koj tuaj yeem tshem tawm ntau lub ntsiab lus ntawm qhov tsis txaus ntseeg hauv cov kav dej sib txuas thaum txo cov kab rov qab poob thiab qhov hnyav.Kuv xav tias qee lub cav nozzles yog 3d luam tawm (superdraco tej zaum?).Kuv vaguely nco qab cov xov xwm ntawm ib co hom luam ntawv hlau bracket ntawm Boeing airliners.
Cov khoom lag luam xws li Navy's tshiab jammers thiab lwm yam kev tsim kho tshiab tuaj yeem muaj ntau cov ntawv luam 3D.Qhov kom zoo dua ntawm topology-optimized qhov chaw yog qhov kev tsom xam lub zog yog kev koom ua ke rau hauv cov txheej txheem tsim thiab kev txheeb xyuas qaug zog yog txuas ncaj qha rau nws.
Txawm li cas los xij, nws yuav yog qee lub sijhawm ua ntej yam zoo li DMLS tiag tiag hauv tsheb thiab kev tsim khoom.Qhov hnyav tseem tsawg dua.
Ib daim ntawv thov uas nws ua haujlwm zoo yog nyob rau hauv hydraulic / pneumatic manifolds.Lub peev xwm los ua cov kab nkhaus thiab kab noj hniav rau shrink qhwv yog qhov tseem ceeb heev.Tsis tas li ntawd, rau cov ntawv pov thawj, koj tseem yuav tau ua 100% kev ntsuas kev ntxhov siab, yog li koj tsis tas yuav muaj kev nyab xeeb loj (qhov kev ntxhov siab zoo nkauj heev).
Qhov teeb meem yog tias ntau lub tuam txhab khav theeb txog kev muaj lub tshuab luam ntawv SLM, tab sis tsawg tus paub siv nws li cas.Cov tshuab luam ntawv no tsuas yog siv rau kev ua qauv sai thiab tsis ua haujlwm feem ntau ntawm lub sijhawm.Raws li qhov no tseem suav tias yog thaj chaw tshiab, cov tshuab luam ntawv xav tias yuav txo qis zoo li mis nyuj thiab yuav tsum tau muab pov tseg hauv 5 xyoos.Qhov no txhais tau hais tias txawm tias tus nqi tiag tiag yuav tsawg heev, tau txais tus nqi tsim nyog rau txoj haujlwm tsim khoom yog qhov nyuaj heev.
Tsis tas li ntawd, kev luam ntawv zoo yog nyob ntawm qhov thermal conductivity ntawm cov khoom, lub ntsiab lus tias txhuas nyhav los tsim qhov roughness uas tuaj yeem ua rau muaj kev ntxhov siab rau kev ua haujlwm tsis zoo (tsis yog ib qho manifold xav tau yog tias koj tab tom tsim rau qhov ntawd).Tsis tas li ntawd, thaum TiAlV6 luam tawm tau zoo heev thiab muaj lub zog zoo dua li qib 5, txhuas feem ntau muaj xws li AlSi10Mg, uas tsis yog cov alloy muaj zog tshaj plaws.T6, thaum tsim nyog rau castings ntawm tib cov khoom, tsis haum rau SLM qhov chaw.Scalmaloy zoo dua tab sis nyuaj rau daim ntawv tso cai, ob peb muab nws, koj tuaj yeem siv Ti nrog cov phab ntsa nyias.
Feem ntau cov tuam txhab tseem xav tau ib txhais caj npab thiab txhais ceg, 20 cov qauv, thiab koj thawj tus menyuam los ua cov ntawv luam tawm.Thaum ua haujlwm nws yog qhov tseem ceeb ib yam li cov tshuab ua haujlwm uas tau coj cov nees luav thiab cov nyiaj npib los ua rau xyoo, lawv xav tias cov ntawv luam tawm yog khawv koob thiab cov neeg siv khoom xav tias lawv muaj hnab ris tob.Tsis tas li ntawd, AS9100 cov tuam txhab muaj ntawv pov thawj feem ntau tsis ua haujlwm luv luv thiab txaus siab ua qhov lawv tau ua ntev ntev thiab paub tias lawv tuaj yeem khwv tau nyiaj los ntawm nws thiab tuaj yeem ua tau yam tsis raug liam ntawm lub dav hlau poob..
Yog li yog: kev lag luam aerospace tuaj yeem tau txais txiaj ntsig los ntawm SLM qhov chaw, thiab qee qhov ntawm lawv ua, tab sis idiosyncrasies ntawm kev lag luam thiab cov tuam txhab uas muab kev pabcuam raug daig hauv 70s, uas ua rau tej yam nyuaj me ntsis.Qhov tsuas yog txoj kev loj hlob tiag tiag yog lub cav, qhov chaw luam ntawv roj injectors tau dhau los ua qhov chaw.Rau peb tus kheej, kev tawm tsam rau kev muab khoom nrog ASML yog kev sib ntaus sib tua.
