Thaum sawv ntxov ntawm lub Ib Hlis 13, 2021, thawj lub ntiaj teb thawj lub tshuab hluav taws xob kub ceev superconducting maglev engineering prototype thiab kab sim siv cov thev naus laus zis qub ntawm Southwest Jiaotong University tau raug tshaj tawm hauv Chengdu, Sichuan xeev, Suav. Nws yog qhov kev tawg tshiab los ntawm kos hauv kev tshawb fawb ntawm qhov project maglev kub ceev superconducting hauv Suav teb thiab peb lub tebchaws muaj cov xwm txheej rau kev sim engineering thiab kev ua qauv qhia.
Cov Ntaub Ntawv Thawj Zaug Hauv Ntiaj Teb; Tsim Ib Qho Qauv Ua Ntej
Qhov kev ua haujlwm ntawm txoj kab kuaj tshuab magnetic levitation kub siab yog thawj zaug hauv ntiaj teb. Nws yog tus sawv cev ntawm Tuam Tshoj txoj kev tsim khoom ntse thiab tsim ib qho piv txwv hauv kev ua haujlwm ntawm kev ua haujlwm kub siab.
Lub tshuab hluav taws xob maglev superconducting kub siab muaj qhov zoo ntawm kev ruaj khov tsis muaj qhov chaw, qauv yooj yim, txuag hluav taws xob, tsis muaj tshuaj lom neeg thiab suab nrov, kev nyab xeeb thiab kev nplij siab, thiab tus nqi ua haujlwm qis. Nws yog ib hom kev thauj mus los ntawm tsheb ciav hlau tshiab zoo tagnrho, haum rau ntau yam kev ceev, tshwj xeeb tshaj yog haum rau kev ua haujlwm ntawm cov kab ceev ceev thiab ultra-high-speed; Cov thev naus laus zis no yog lub tshuab hluav taws xob maglev superconducting kub siab nrog tus kheej-nres, tus kheej-kev coj tus kheej, thiab tus kheej-kev ruaj khov. Nws yog ib txoj kev thauj mus los ntawm tsheb ciav hlau tshiab uas tab tom ntsib kev txhim kho yav tom ntej thiab kev siv dav dav. Cov thev naus laus zis no yog thawj zaug uas tau tsim hauv ib puag ncig huab cua, thiab qhov kev cia siab ntawm kev ua haujlwm ceev yog ntau dua 600 km / h, uas xav tias yuav tsim cov ntaub ntawv tshiab rau kev khiav tsheb hauv av hauv ib puag ncig huab cua.
Cov kauj ruam tom ntej yog kev sib txuas cov thev naus laus zis ntawm cov kav dej nqus tsev yav tom ntej los tsim kom muaj kev thauj mus los uas ua tiav cov qhov sib txawv ntawm kev thauj mus los hauv av thiab kev thauj mus los hauv huab cua, uas yuav tso lub hauv paus rau kev tawg mus sij hawm ntev hauv kev ceev tshaj 1000 km / teev, yog li tsim kom muaj tus qauv tshiab ntawm kev thauj mus los hauv av. Kev hloov pauv yav tom ntej thiab kev cuam tshuam hauv kev txhim kho kev thauj mus los ntawm tsheb ciav hlau.

Kev Siv Tshuab Sib Nqus Levitation
Tam sim no, muaj peb lub thev naus laus zis "super magnetic levitation" hauv ntiaj teb.
Kev siv tshuab electromagnetic levitation hauv lub teb chaws Yelemees:
Lub hauv paus ntsiab lus electromagnetic yog siv los ua kom pom qhov levitation ntawm lub tsheb ciav hlau thiab txoj kev. Tam sim no, lub tsheb ciav hlau Shanghai maglev, lub tsheb ciav hlau maglev uas tab tom tsim hauv Changsha thiab Beijing yog txhua tus nyob hauv lub tsheb ciav hlau no.
Nyiv lub tshuab hluav taws xob sib nqus superconducting kub qis:
Siv cov khoom siv superconducting ntawm qee cov ntaub ntawv ntawm qhov kub qis (txias rau -269 ° C nrog cov kua helium) los ua kom lub tsheb ciav hlau lev, xws li Shinkansen maglev kab hauv Nyiv Pooj.
Tuam Tshoj txoj kev siv tshuab sib nqus superconducting kub siab:
Lub hauv paus ntsiab lus zoo ib yam li qhov kub qis superconductivity, tab sis nws qhov kub ua haujlwm yog -196 ° C.
Hauv cov kev sim ua ntej, qhov kev sib nqus levitation no hauv peb lub tebchaws tsis tuaj yeem raug ncua xwb tab sis kuj raug ncua.

Cov txiaj ntsig ntawm High Temperature Superconducting Maglev Tsheb ciav hlau
Kev txuag hluav taws xob:Kev nce thiab kev taw qhia tsis tas yuav tsum muaj kev tswj hwm lossis lub zog ntawm lub tsheb, thiab lub kaw lus yooj yim heev. Kev ncua thiab kev taw qhia tsuas yog yuav tsum tau txias nrog cov kua nitrogen pheej yig (77 K), thiab 78% ntawm huab cua yog nitrogen.
Kev tiv thaiv ib puag ncig:Qhov kub siab superconducting magnetic levitation tuaj yeem levitation statically, kiag li tsis muaj suab nrov; txoj kab hlau nplaum tas mus li tsim lub teb magnetic static, thiab lub teb magnetic nyob rau hauv qhov chaw uas cov neeg caij tsheb kov yog xoom, thiab tsis muaj electromagnetic pa phem.
Kev kub ceev:Qhov siab ntawm lub zog levitation (10 ~ 30 hli) tuaj yeem tsim raws li qhov xav tau, thiab nws tuaj yeem siv los khiav ntawm qhov tsis hloov pauv mus rau qhov qis, nruab nrab, siab ceev thiab ceev heev. Piv nrog rau lwm cov thev naus laus zis sib nqus levitation, nws tsim nyog dua rau kev thauj mus los ntawm cov kav dej nqus tsev (ntau dua 1000 km / teev).
Kev Nyab Xeeb:Lub zog levitation nce ntxiv exponentially nrog rau qhov txo qis ntawm qhov siab levitation, thiab kev nyab xeeb ntawm kev ua haujlwm tuaj yeem ua kom ntseeg tau tias tsis muaj kev tswj hwm hauv kev taw qhia ntsug. Lub kaw lus tswj tus kheej kuj tseem tuaj yeem ua kom muaj kev nyab xeeb hauv kev taw qhia kab rov tav.
Kev nplij siab:Lub zog tshwj xeeb "pinning force" ntawm lub superconductor kub siab ua rau lub cev tsheb ruaj khov rau saum thiab nqis, uas yog qhov ruaj khov uas nyuaj rau txhua lub tsheb ua tiav. Qhov uas cov neeg caij tsheb ntsib thaum caij yog "qhov kev xav tsis muaj kev xav".
Tus nqi khiav lag luam qis:Piv nrog rau lub tsheb German uas siv hluav taws xob tas mus li thiab lub tsheb Nyiv Pooj uas siv hluav taws xob tsawg uas siv cov kua helium, nws muaj qhov zoo ntawm qhov hnyav sib dua, cov qauv yooj yim, thiab cov nqi tsim khoom thiab kev ua haujlwm tsawg.
Kev Siv Tshuaj Nitrogen Ua Kua
Vim yog cov yam ntxwv ntawm cov superconductors, cov superconductor yuav tsum tau muab tso rau hauv ib puag ncig kua nitrogen ntawm -196 ℃ thaum lub sijhawm ua haujlwm.
Kev siv hluav taws xob sib nqus kub siab yog ib txoj kev siv tshuab uas siv cov yam ntxwv ntawm cov khoom siv hluav taws xob kub siab los ua kom ruaj khov yam tsis muaj kev tswj hwm.
Lub Tsheb Thauj Khoom Ua Kua Nitrogen
Lub tsheb thauj khoom ua kua nitrogen yog cov khoom tsim thiab tsim los ntawm Sichuan Haishengjie Cryogenic Technology Co., Ltd. rau qhov project maglev kub siab superconducting high-speed. Nws yog lub hauv paus ntawm maglev technology-Dewar ntxiv kua nitrogen.

Kev tsim qauv txawb, kev ua haujlwm ua kua nitrogen rov ua dua tuaj yeem ua tiav ncaj qha ntawm lub tsheb ciav hlau.
Lub tshuab ua kua nitrogen semi-automatic tuaj yeem muab 6 lub dewars nrog kua nitrogen tib lub sijhawm.
Lub kaw lus tswj hwm ywj pheej rau txoj kev, txhua qhov chaw ntim khoom tuaj yeem tswj tau ib tus zuj zus.
Kev tiv thaiv siab qis, tiv thaiv sab hauv ntawm Dewar thaum lub sijhawm rov ua dua tshiab.
Kev tiv thaiv hluav taws xob 24V.
Lub Tank Muab Khoom Siv Uas Muaj Siab Rau Nws Tus Kheej
Nws yog lub tank uas muaj lub siab tswj tus kheej uas tsim tshwj xeeb thiab tsim los rau kev khaws cia cov kua nitrogen. Nws yeej ib txwm ua raws li cov qauv tsim kev nyab xeeb, zoo heev rau kev tsim khoom thiab khaws cia cov kua nitrogen ntev.
