Cov Neeg Tawm Tsam Hauv New York Txhim Kho Kev Lag Luam Hauv Dej Hiav Txwv Submarines 3D Luam Ntawv Ua Npuas Ncauj

Cov ntaub ntawv kev tshawb fawb pab pawg ntawm New York University Tanden Engineering Institute tau tsim 3D luam tawm cov txheej txheem ua npuas dej rau kev siv hauv kev kho tsheb, dav hlau, kev lag luam tub rog thiab nkoj hiav txwv.

Cov ua npuas dej ua ke muaj qhov sib xyaw ntawm cov khoob khoob khawm me me los yog iav spheres thiab ib qho epoxy lossis cov khoom siv yas yas. Cov khoom siv no nrov heev hauv kev tsim kev lag luam, vim nws muaj zog thiab lub teeb yuag, thiab tag nrho buoyancy. (Nkag siab, peb tus yam ntxwv no ua rau nws muaj txiaj ntsig tshwj xeeb hauv kev tsim khoom qab nkoj.)

Pab pawg tau hais tias lub peev xwm ntawm 3D-luam ntawv ua npuas ncauj los txhim kho cov compression thiab lub zog ntawm ntau qhov chaw nyuaj thiab thiaj li txhim kho qhov tam sim no siv txhaj tshuaj-ua npuas ua npuas.

Pawg neeg tshawb nrhiav tsim cov kab ntawv luam tawm uas muaj cov microspheres muaj qhov sib xyaw ntawm high-ntom polyethylene (HDPE) thiab cov khoom siv yoov rov ua dua tshiab (ib qho ntawm cov khoom ntawm cov roj sib txuas). Cov npuas dej ua ke no tuaj yeem luam tawm ntawm cov tshuab luam tawm 3D thiab rov ua dua tshiab.

Nikhil Gupta, tus kws tshaj lij ntawm kev siv tshuab thiab kev tsim kho aerospace ntawm qhov haujlwm, hais tias: "Peb lub hom phiaj yog kev tsim kho vajtse uas tuaj yeem siv rau hauv kev lag luam luam ntawv yam tsis hloov lub tshuab luam ntawv. , kub thiab luam tawm.Qhov nrhiav qhov tsim kom zoo tshaj plaws ntawm cov luam ntawv yog tus yuam sij rau kev ua cov ntawv luam ntawv tau zoo.

Lub hauv paus tseem ceeb hauv kev txhim kho cov ntxaij lim dej yog nrhiav qhov loj me rau cov hollow microspheres kom lawv tuaj yeem yooj yim dhau ntawm lub tshuab luam ntawv no tsis muaj qhov txhaws. Thaum kawg, microspheres ntau ntawm txoj kab uas hla ntawm 0.04 hli txog 0.07 hli thiab yooj yim dhau los ntawm tus qauv 1.7 hli tshuab luam ntawv nozzle.

Nws tau tshaj tawm tias 3D luam tawm ua npuas dej yog sib piv rau kev txhaj tshuaj pwm ua haujlwm ntawm qhov ua kom zoo li lub zog thiab qhov ntom ntom. Cov pab pawg tam sim no tseem tabtom yuav ua li cas txhawm rau txhawm rau txhim kho kev tsav nkoj hauv qab nkoj uas tuaj yeem ua haujlwm ntawm qhov tob.
