Kumanani ndi magawo osindikizidwa a 3D omwe atsala pang'ono kupita ku Mars |Hyundai Machinery Workshop

Zigawo zisanu za chida chofunikiracho zimapangidwa ndi kusungunuka kwa ma elekitironi, komwe kumatha kutumiza matabwa a mabokosi opanda pake ndi makoma owonda.Koma kusindikiza kwa 3D ndi sitepe yoyamba yokha.
Chida chogwiritsidwa ntchito pojambula ndi PIXL, chipangizo cha X-ray cha petrochemical chomwe chimatha kusanthula miyala ya Mars.Gwero la chithunzichi ndi pamwambapa: NASA / JPL-Caltech
Pa February 18, pamene "Perseverance" rover inatera pa Mars, idzanyamula pafupifupi magawo khumi azitsulo osindikizidwa a 3D.Zigawo zisanu mwa izi zipezeka mu zida zofunika kwambiri pa ntchito ya rover: X-ray Petrochemical Planetary Instrument kapena PIXL.PIXL, yoyikidwa kumapeto kwa cantilever ya rover, idzasanthula zitsanzo za miyala ndi nthaka pamwamba pa Red Planet kuti zithandize kuwunika momwe moyo ungathere kumeneko.
Magawo osindikizidwa a PIXL a 3D amaphatikiza chivundikiro chakutsogolo ndi chakumbuyo chakumbuyo, chimango chokwera, tebulo la X-ray ndi chithandizo chatebulo.Poyang'ana koyamba, zimawoneka ngati zing'onozing'ono, zina zokhala ndi mipanda yopyapyala ndi mabokosi, zikhoza kukhala zopangidwa ndi zitsulo zopangidwa ndi pepala.Komabe, zikuwoneka kuti zofunikira kwambiri za chida ichi (ndi rover yonse) zimagwirizana ndi kuchuluka kwa masitepe opangira pambuyo popanga zowonjezera (AM).
Pamene mainjiniya a NASA's Jet Propulsion Laboratory (JPL) adapanga PIXL, sanakonzekere kupanga zida zoyenera kusindikiza kwa 3D.M'malo mwake, amatsatira "bajeti" yokhazikika pomwe amayang'ana kwambiri magwiridwe antchito ndikupanga zida zomwe zitha kukwaniritsa ntchitoyi.Kulemera kopatsidwa kwa PIXL ndi mapaundi a 16 okha;kupitilira bajeti iyi kupangitsa chipangizocho kapena zoyeserera zina "kulumpha" kuchokera pa rover.
Ngakhale kuti mbalizo zimawoneka zosavuta, kuchepetsa kulemera kumeneku kuyenera kuganiziridwa popanga.X-ray workbench, chimango chothandizira ndi chimango choyikira zonse zimatenga chotchinga chopanda kanthu kuti asatengere zolemetsa kapena zida zina, ndipo khoma la chipolopolocho ndi lopyapyala ndipo mawonekedwewo amatsekereza chidacho.
Magawo asanu osindikizidwa a PIXL a 3D amawoneka ngati mabakiti osavuta ndi zida zanyumba, koma bajeti yokhazikika imafuna kuti magawowa azikhala ndi makoma owonda kwambiri komanso mabokosi opanda pake, omwe amachotsa njira yopangira yomwe imagwiritsidwa ntchito popanga.Gwero la zithunzi: Carpenter Additives
Pofuna kupanga zinyumba zopepuka komanso zolimba, NASA idatembenukira kwa Carpenter Additive, yemwe amapereka ufa wachitsulo ndi ntchito zosindikizira za 3D.Popeza pali malo ochepa osinthira kapena kusintha mapangidwe a ziwalo zopepukazi, Carpenter Additive anasankha electron beam melting (EBM) ngati njira yabwino kwambiri yopangira.Njira yosindikizira yachitsulo ya 3D iyi imatha kupanga matabwa a mabokosi opanda kanthu, makoma owonda ndi zina zomwe zimafunikira ndi kapangidwe ka NASA.Komabe, kusindikiza kwa 3D ndi gawo loyamba lokha popanga.
Kusungunuka kwa mtengo wa elektroni ndi njira yosungunula ufa yomwe imagwiritsa ntchito mtengo wa elekitironi ngati gwero lamphamvu kuti musankhe zitsulo zachitsulo pamodzi.Makina onsewa amatenthedwa, kusindikiza kukuchitika pa kutentha kokwezeka kumeneku, mbali zake zimatenthedwa ndi kutentha pamene zigawozo zimasindikizidwa, ndipo ufa wozungulira ndi theka-sintered.
Poyerekeza ndi njira zofananira zachitsulo chowongolera laser (DMLS), EBM imatha kupanga zomaliza zowoneka bwino komanso zokulirapo, koma zabwino zake ndikuti zimachepetsa kufunikira kwa zida zothandizira ndikupewa kufunikira kwa njira zopangira laser.Thermal stresss zomwe zingakhale zovuta.Zigawo za PIXL zimatuluka munjira ya EBM, ndizokulirapo pang'ono, zimakhala zowoneka bwino, ndipo zimatchera makeke a ufa mu geometry yopanda kanthu.
Electron beam melting (EBM) imatha kupereka mitundu yovuta ya magawo a PIXL, koma kuti amalize, njira zingapo zosinthira pambuyo pake ziyenera kuchitika.Gwero la zithunzi: Carpenter Additives
Monga tafotokozera pamwambapa, kuti mukwaniritse kukula komaliza, kutsirizitsa pamwamba ndi kulemera kwa zigawo za PIXL, ndondomeko yotsatila pambuyo pake iyenera kuchitidwa.Njira zonse zamakina ndi zamankhwala zimagwiritsidwa ntchito pochotsa ufa wotsalira ndikusalaza pamwamba.Kuyendera pakati pa sitepe iliyonse kumatsimikizira ubwino wa ndondomeko yonse.Zolemba zomaliza ndi 22 magalamu apamwamba kuposa bajeti yonse, yomwe idakali mkati mwazovomerezeka.
Kuti mumve zambiri za momwe zigawozi zimapangidwira (kuphatikiza kukula komwe kumakhudzidwa ndi kusindikiza kwa 3D, mapangidwe azinthu zosakhalitsa komanso zokhazikika, komanso tsatanetsatane wochotsa ufa), chonde onani phunziro ili ndikuwonera nkhani yaposachedwa ya The Cool. Magawo Onetsani Kuti mumvetsetse chifukwa chake, pakusindikiza kwa 3D, iyi ndi nkhani yachilendo yopanga.
Mu carbon fiber reinforced plastics (CFRP), njira yochotsera zinthu ikuphwanyidwa osati kumeta ubweya.Izi zimapangitsa kuti ikhale yosiyana ndi mapulogalamu ena opangira.
Pogwiritsa ntchito geometry yapadera yodula mphero ndikuwonjezera zokutira zolimba pamalo osalala, Toolmex Corp. yapanga mphero yomwe ili yoyenera kudulira aluminiyamu mwachangu.Chidachi chimatchedwa "Mako" ndipo ndi gawo lazida zamakampani a SharC.
