Cornell University Txhawb Kev Tsim Tsa Tshiab 3D Tshuab Luam Ntawv

Raws li tsab ntawv tshaj tawm ntawm lub vev xaib materialsstoday lub Kaum Ib Hlis 16, 2020, tsis ntev los no, ib pawg kws tshawb fawb tau coj los ntawm Assistant Professor Atieh Moridi ntawm Seebury Lub Tsev Kawm Ntawv ntawm Mechanical thiab Aerospace Engineering ntawm Cornell University tau qhia txog hom 3D tshiab hauv Cov Ntawv Siv Khoom Siv. Txoj kev ntawm kev ua kom ntxig cov khoom siv hlau.

Lub tshuab txau txias feem ntau siv tam sim no 3D luam ntawv hlau feem ntau txau cov hmoov hlau mus rau cov txheej txheem hauv cov tub ntxhais ua haujlwm ntawm qhov ceev ntawm 10 meters ib ob, thiab tom qab ntawd ua rau cov hlau txhawm rau txhaws cov hlau sib xyaw ua ke. Qhov kub ua kom sov siab yuav dhau lub sijhawm melting ntawm cov hlau, uas yuav ua rau qhov loj me ntawm tus qauv hloov pauv ntawm qhov pib tsim.

Atieh Moridi pawg kws tshawb fawb tau ua ob txoj kev txhim kho rau 3D luam ntawv thev naus laus zis: ib qho yog nce dav hlau dav hlau ntawm titanium alloy hais nrog lub taub ntawm 45-106 microns los ntawm 10 meters ib ob mus rau 600 metres ib ob, uas tau mus txog tus qauv supersonic. Cov. ; Qhov thib ob yog tswj cov cua kub kub ntawm cov hlau ntawm 900 ° C (deb qis dua qhov taw tes melting ntawm titanium hlau, 1626 ° C). Los ntawm cov kev txhim kho no, lub zog ntawm cov ntxeem tau cov qauv tsim cov lag luam los ntawm cov pawg tau nce li 42%.

Atieh Moridi ntseeg hais tias hom tshiab 3D luam ntawv tshuab no muaj peev xwm thov kev lag luam zoo hauv kev tsim kho, tsheb thauj mus los, lub zog thiab lwm yam kev lag luam.
