ULTRASONIC ADDITIVE MANUFACTURING
Lub hwj chim ntawm lub suab sib tshooj ntawm cov ntaub ntawv pov thawj rau cov hluav taws xob tawg thiab ntau dua.
Ib qho 3D hlau luam txheej txheem uas siv cov khoom siv rau patented ultrasonic additive (UAM) siv lub suab tsis ua ke tshooj ntawm cov ntawv nyiaj hlau. Cov tshuab no tuaj yeem tsim cov khoom sib txuam nrog cov nta thiab cov cwj pwm tsis tau los ntawm cov qauv kev coj ua.
Fabrisonic 3D-sau cov khaubncaws sab nraud povtseg ntawm 6061 txhuas thiab 0.008 "tuab tantalum ntawv ci los qhia tias cov khoom siv hluav taws xob thiab hluav taws xob tiv thaiv tuaj yeem ua ke rau hauv ib lub vaj huam sib luag monolithic.
Tantalum, tsawg kawg, zas hlau hloov hlau nrog lub siab melting taw tes, muaj lub siab tiv thaiv corrosion, thiab nws cov high atomic number (Z) ua rau nws siv hluav taws xob shielding.
Satellites tau ntev siv cov txheej txheej ntawm txhuas, titanium, thiab tantalum los tsim ib tus qauv hauv qib Z. Qhov sib txawv ntawm cov hlau 'Z qhov tseem ceeb ua rau muaj kev lim zoo nrog lub dav spectrum of radiation, tiv thaiv rhiab hauv hluav taws xob thiab txo cov suab paj nruag hauv kev teeb liab. Xws li, kev xeem tau-Z-shielding tseem yuav ua dua thiab thinner dua cov khoom siv shielding.
Txij li UAM tau yooj yim ua ke cov teeb meem sib txawv, Fabrisonic tau 3D luam yam khoom siv nrog ntau yam khoom Z-tooj hauv ib qho kev tivthaiv. Qhov no txwv ib feem suav thiab tshem tawm txoj haujlwm kev ua haujlwm.
Mark Norfolk, tus thawj tswj hwm ntawm Fabrisonic, hais tias UAM txhuam cov oxides ntawm cov hlau uas yuav tsum tau koom ua ke, uas cia lawv ua kom muaj zog, txheeb nyiaj hlau. Nrog rau qhov sib ntxiv ntawm me ntsis siab thiab thaum tshav kub, UAM tuaj yeem ua ib lub strip 1 "dav los ntawm qhov yuav luag txhua qhov ntev, thaum nce mus txog 300pm Panels li loj li 6ft x 6ft tuaj yeem sib sau los ntawm cov kab ntawv no.
Vim tias qhov txheej txheem tshwm sim ntawm qhov kub thiab txias (200 ° F ncov rau aluminium), nws muaj peev xwm mus embedded electronics mus rau hauv siab tuab hlau metallic panels, xws li cov kab mob gage, thermo-couples, lossis fiber-optic cables.
Tej khoom siv hlau, xws li cov tooj liab, txhuas, thiab titanium laminate, tuaj yeem ua rau txoj cai UAM.
Hlau 3D printing technologies muaj cov lus cog tseg ntawm kev tsim cov khoom nrog cov txheej txheem ntawm cov txheej txheem tsis tau nrog cov qauv kev tsim khoom, nrog rau qhov chaw siv ntau hom hlau uas muaj hauv tib qho thiab hauv cov qauv duab.
"Peb tab tom ua tej yam uas ua rau muaj kev ruaj khov thiab muaj kev tiv thaiv zoo nkauj, feem ntau ob nti," Norfolk piav qhia. Tus nqi thiab cov nyhav nyhav los ntawm kev sib xyaw ua ke ntawm ib qho.
Norfolk piav tias, "ASTM muaj ib qho kev qhia tshwj xeeb rau kev tsim khoom ntxiv (AM) uas lees paub ntau txoj kev, nrog rau daim ntawv phom sij. Peb siv cov txheej txheem ntawm lub xeev los tsim cov txheej txheej ntawm cov txheej txheem - qee qhov feem pua ntawm cov ntawv khoob ntawm cov ntawv khawm - xws li 0.005 "rau 0.010" tuab. "Norfolk ntxiv tias cov hlau foils tsawg dua cov hmoov thiab muaj los ntawm ntau qhov chaw .
Lub tuam txhab kuj 3D luam tawm high-performance, sib pauv kub heaters los ntawm combining txhuas thiab tooj liab hauv designs uas yuav nyuaj ua nrog tsoos raug. "Peb tuaj yeem luam cov looj tsau txias rau hauv tus qauv ntawm lub satellite kom cov kab xev tuaj yeem ua hluav taws xob kub heev," Norfolk hais tias.
