Ib ceg tseem ceeb ntawm kev tsim khoom ntxiv, hlau 3D luam ntawv ntiav cov qauv digital los tswj cov melting thiab stacking ntawm hlau hmoov txheej los ntawm txheej los tsim cov khoom siv. Ntawm nws cov haujlwm yooj yim yog electron beam melting (EBM) thiab xaiv laser melting (SLM). Nyob rau hauv SLM, siab - lub zog laser beams yog siv los yaj cov hmoov hlau, tso cai rau txheej txheej - los ntawm - txheej txheej ntawm cov txheej txheem nyuaj los ntawm kev tswj xyuas meej ntawm txoj kev laser scanning. Raws li Siemens Energy txoj hauv kev, nws SLM- ua cov roj turbine burner ua ke 13 welded Cheebtsam rau hauv ib chav tsev, ua kom ntev lub neej thiab kev vam khom.
Muaj peb qhov txiaj ntsig tseem ceeb ntawm cov cuab yeej no: ua ntej, nws siv ntau dua 95% ntawm cov khoom siv, uas zoo dua li 60% -70% siv hauv cov txheej txheem casting tsis tu ncua; thib ob, nws tuaj yeem tsim cov duab nyuaj uas nyuaj ua nrog cov txheej txheem ib txwm ua, zoo li cov qauv honeycomb rau cua txias hauv lub tog raj kheej taub hau; thiab thib peb, los ntawm optimizing tus tsim, qhov chaw yuav ua tau 30% -70% sib dua thaum tseem muaj zog. Siv hlau 3D luam ntawv, Siemens Energy txoj kev tshawb fawb tau pom tias qhov hnyav ntawm lub tog raj kheej taub hau poob los ntawm 5095 grams mus rau 1755 grams, yog li ua rau 65% txo qhov ntim thiab 40% nce hauv kev ua kom sov.
Los ntawm txoj kev daws teeb meem ntawm Cov Khoom Siv, Siemens Zog tau tsim cov txheej txheem tsim khoom siv cuaj caum muaj hlau 3D tshuab luam ntawv. Siv SLM thev naus laus zis, cov roj turbine hniav ua tau tsim los txhim kho cov huab cua hauv lawv los ntawm kev ua raws li qhov xwm txheej, uas yuav pab hlawv roj ntau dua thiab txo qhov xav tau cua txias. Qhov tshiab thev naus laus zis nyob hauv cov khoom siv tshiab: kev tsim cov nickel-raws li alloy hmoov haum rau siab- qhov kub thiab txias, uas tuaj yeem ua rau lub neej ua haujlwm ntawm 100,000 teev ntawm 650℃.
Tailored manufacturing ntawm cov hniav flashers tau ua tiav los ntawm 3D hlau luam ntawv thev naus laus zis los daws cov teeb meem ntawm kev tsim cov hniav, uas tso siab rau cov pwm thiab ua rau cov nqi siab. Topological optimization tsim tau txo cov xob laim qhov hnyav los ntawm plaub caug feem pua thiab tripled lub installation efficiency. Cov thev naus laus zis no tuaj yeem txo tus nqi txij nkawm los ntawm 20% thiab txhim kho kev lag luam tag nrho lub neej ntawm lub zog ntawm lub zog- tsim cov khoom siv hauv cov ntsiab lus ntawm lub zog cua sab nraud.
3D hlau luam ntawv tau daws qhov teeb meem nyuaj ntawm machining microchannels uas nyuaj rau ncav cuag nrog cov qauv siv hauv kev hloov pauv ntawm microturbine xyaw. UFor a 50mm microair-cooled turbine ua piv txwv, phab ntsa tuab ntawm cov cua txias channel tsim los ntawm 3D luam ntawv tsuas yog 0.3 hli, yog li txhim kho qhov ua kom txias txias los ntawm 50% thiab tau txais lub zog ntom ntom peb zaug siab dua li cov qauv tsim.
Peb qhov ntev iav qhov peb -fold daim ntawv thov nqi ntawm hlau 3D luam ntawv hauv lub zog sector:
AA Raws li Siemens Energy cov kev coj ua, cov cuab yeej siv tau nce los ntawm 200%, thaum lub voj voog ntau lawm rau cov khoom siv hluav taws xob ua nrog 3D luam ntawv tau raug txiav los ntawm 12 lub lis piam hauv cov qauv siv rau 4 lub lis piam. Kev tsim kho ntawm cov hniav flashers tau txo lub sijhawm xa khoom los ntawm 60 hnub mus rau 7 hnub nkaus xwb hauv cov khoom siv hluav taws xob cua, yog li ua tau raws li qhov kev thov rau cov lus teb ceev hauv khw.
DA ncaj qha txo cov nqi tsim khoom los ntawm kev siv cov ntaub ntawv zoo dua. UUsing gas turbine blades ua piv txwv, cov txheej txheem kev ua haujlwm zoo li qub pov tseg txog 30% ntawm cov ntaub ntawv, thaum 3D luam ntawv ua rau tsuas yog 5% poob ntawm cov ntaub ntawv txhawb nqa. Hauv kev lag luam ntawm cov khoom siv hluav taws xob ua haujlwm thiab kev saib xyuas, 3D luam ntawv thev naus laus zis tau txo cov sij hawm ua haujlwm rau hauv 24 teev thiab txo cov nqi ntawm cov khoom muag los ntawm 40%.
Topology optimization tsim ua rau kom lub tshav kub dissipation cheeb tsam ntawm lub cav lub tog raj kheej taub hau los ntawm 80%, uas ua rau ib tug 66% txo qhov hnyav. IIn the field of microenergy equipment, 3D printing technology tau ua tiav kev tsim cov microchannels ntawm qib 0.1mm, yog li muab lub sijhawm rau kev tsim tshiab ntawm cov khoom tseem ceeb, xws li roj cell bipolar daim hlau.
Txawm hais tias muaj txiaj ntsig zoo tshaj plaws, kev siv hlau 3D luam ntawv hauv lub zog ua haujlwm tseem muaj peb qhov teeb meem loj.
T Qhov kev txwv tsis pub siv cov hmoov hlau tam sim no hauv siab - cov khoom siv siab yog vim lawv lub zog qaug zog yog 15% mus rau 20% qis dua li cov khoom tsim. Tus yuam sij rau kev vam meej yog tsim cov khoom tshiab, zoo li tshwj xeeb titanium alloys ua nrog laser additive manufacturing, uas tuaj yeem ua tiav lub zog ntawm 900 MPa lossis ntau dua.
Cov txheej txheem optimization tseem yuav tsum tau kov yeej qhov sib txawv ntawm qhov sib txawv los ntawm thermal deformation. UBy siv ntau-physics simulation thev naus laus zis, Siemens Zog tswj qhov tseeb qhov tseeb ntawm lub tog raj kheej taub hau kom tsis pub dhau ± 0.05mm, uas yog 50% ntau meej dua li cov qauv kev cai tso cai.
Tsis muaj ntawv pov thawj kev lag luam rau 3D - cov khoom siv hluav taws xob luam tawm. EE Tsim kom muaj ib qho kev qhia dav dav ntawm cov txheej txheem txheej txheem uas suav nrog cov khoom siv, cov txheej txheem, thiab kev sim yog ib feem ntawm txoj hauv kev tam sim no. Rau cov hlau 3D- cov khoom luam tawm, piv txwv li, German VDI 3405 tus qauv tau tsim cov txheej txheem ntawm kev ua haujlwm qaug zog.
