Laser Poob Siab: Kev Tawm Tsam ntawm Cov Nto Muaj zog ntawm kev txhawb nqa kev siv tshuab los ntawm kev kuaj cov chaw nyob
Laser Shock Beening Technology Teas, cov txheej txheem tshiab lub npe hu ua "cov khoom saum npoo ntxiv dag zog", yog ntsiag to rov kho cov toj roob hauv pes. Los ntawm thawj lub ntsej muag hloov ntawm microstructure ntawm txhuas alloy hauv Asmeskas Kev Lag Luam Kev Lag Luam ntawm Boeing 777 Hniav kev ua; Los ntawm lub hnub yug ntawm thawj zaug mem tes ntau lawm kab hauv Suav teb ntau dua ntawm kev ua kom tiav ntawm cov anti {{4 4}} npuas} Kev tiv thaiv "ntawm cov hlau nto.
Thaum lub nanosecond Laser Beam tsoo nrog cov hlau, cov vaporization ntawm lub zog nqus dej yog zoo li lub zog hluav taws xob tsis txaus ntseeg ntawm cov khoom siv sib xyaw ua ke hauv cov khoom siv. Kev xaiv ntawm Constrain txheej yog zoo li tailoring - Cov xim dub tab sis nyuaj rau tshem tawm, thiab qhov yooj yim ntawm txhuas ntawv ci ua thawj zaug xaiv. Nyob rau hauv thaj teb ntawm cov lej kev sim ua kom meej meej, cov kev txhim kho ntawm cov qauv hloov kho tau zoo dua los ntawm "kev sim siab thiab ua yuam kev" kom "muaj kev ua txhaum".
Qhov no tsis yog kev hloov pauv ntawm kev tsim thev naus laus zis, tab sis kuj tshaj tawm ntawm kev tsim khoom lag luam rau "twv qhov txwv": Lub zog uas "lub siab tau txais kev cuam tshuam li cas? Yuav ua li cas thiaj tuaj yeem ua tus kab hluav taws xob Nuclear Weld withstand kaum ntawm lub siab? Cov kev cog pa roj ntsha tau pom qhov sib npaug ntawm kev nruj thiab kev tsis txaus siab? Laser Shock chaening yog siv lub zog ntawm photons los sau cov lus teb rau cov teeb meem nyuaj no.
Laser Shock Caum Deening Technology, tseem hu ua Laser Tua Caum, yog qhov tshiab, ua tau zoo thiab txhim kho cov thev naus laus zis sai sai. Piv nrog tsoos mechanical tua peening technology, nws tuaj yeem ua cov txheej txheem sib xyaw ua ke ntawm cov txheej txheem sib xyaw ua ke, thiab muaj peev xwm daws qhov nyuaj {{2} kov qhov chaw. Tam sim no, cov thev naus laus zis no tau siv hauv kev nkees- tiv taus cov dav hlau cav, thiab lub zog nuclear, thiab lub zog nuclear cog lus. Nrog rau kev poob qis ntxiv nyob rau hauv tus nqi ntawm laser khoom, laser shourope technology thev naus laus zis yuav siv ntau dua.
Laser Shock Beening Technology Technology yog siv dav hauv kev tsim khoom.
Xyoo 1972, Tebchaws Asmeskas siv siab- lub zog aliet {}}} Lub zog alloys rau kev tshawb fawb laser poob rau laser shoppe kev tshawb fawb. Nyob rau xyoo 1980s, cov teb chaws xws li cov cheeb tsam xws li Tebchaws Europe, Nyij Pooj, thiab cov neeg Ixayees tau nqa tawm ntawm laser poob siab Teening Technology.
Xyoo 1995, lub ntiaj teb thawj thawj Laser Shocker Technology tuam txhab tau tsim hauv Tebchaws Asmeskas. Xyoo 1997, General Motors tau siv laser poob siab siv thev naus laus zis, txhim kho lawv txoj kev ua siab loj rau cov khoom puas txawv teb chaws. Xyoo 2001, Asmeskas Laser Laser Poob Siab Ua Lag Luam Ua Lag Luam Laser Shock Chase ntawm ntau dua 800 lub cav ntawm yob- royce. Hauv xyoo 2004, lub tuam txhab koom tes nrog Asmeskas cov kev ntsuas huab cua ua haujlwm ntawm lub cav titanium tov rau ntawm f /} {13, thiab nws qaug zog tau ob npaug. Nyob rau tib lub xyoo, Tebchaws Asmeskas tau tshaj tawm txoj kev ua haujlwm Laser Laser Laser Laser Lasing. Nyob rau hauv lub xeev ua tiav cov cuab yeej siv txawb Lasing. Xyoo 2002, Toshiba Corporation ntawm Nyiv Siv cov txheej txheem me me xws li nuclear reactor siab cov hlab ntsha thiab cov pob txha sib luag los txhim kho lub neej qaug zog ntawm qhov chaw.
Cov kws tshawb fawb txawv teb chaws kuj tseem tau siv Laser Shock ua thev naus laus zis thiab cov khoom siv tsis zoo, ua rau muaj kev cuam tshuam tsis zoo, ua kom muaj zog ntawm cov calcium - cov khoom siv hlau nplaum.
Kev tshawb fawb hauv tsev ntawm Laser Poob Siab Technology tau pib hauv xyoo 1990, feem ntau yog kev sib tham ntawm kev sim ntawm aluminium alloys thiab cov hlau. Txij li xyoo 1992, Nanjing University of Aeronautics thiab Astronautics tau koom tes nrog Tuam Txhab Nyiaj Txiag ntawm Laser Sead DeAtening ntawm Aviation cheeb tsam. Xyoo 1995, thawj Laser Poob Zog Ntxiv rau cov khoom siv rau kev sim ua tiav ntawm lub tsev kawm qib siab ntawm kev tshawb fawb thiab thev naus laus zis ntawm Suav. Hauv xyoo 2008, lub zog cua Aperitionering University, ua ke nrog Xi'an Optoelectronic Technology Co., Ltd. Hauv xyoo 2011, kuv lub teb chaws thawj txheej ntawm kev sib xyaw ua ke Laser Laser Lub Tsev Ua Haujlwm ntawm Lub Tuam Txhab Shenyang lub koom haum, thiab xa mus rau Shenyang Liming Cool, Ltd. Rau kev siv.
Mechanism thiab cuam tshuam txog kev cuam tshuam ntawm laser shoppe dej hiav txwv
When a laser beam with a power density greater than 10⁹W/cm² and a pulse width of nanoseconds irradiates the metal surface, the energy absorption layer absorbs the laser energy and undergoes explosive vaporization and evaporation, generating a high-temperature (>10⁷K) and high-pressure (>1GPA) Plasma txheej. Laser Shock Chaening siv rau nthwv dej poob siab tshaj tawm rau hauv cov khoom siv los ntawm kev cuam tshuam los ntawm qhov siab {2} kub txheej ntawm lub hom phiaj.
Cov ntaub ntawv txwv cov khoom tam sim no siv suav nrog K9 kho lub khob iav, organic iav thiab dej ntws txheej. Cov iav cov khoom tau txwv tsis pub muaj cov nyhuv zoo, tab sis muaj kev hloov kho tsis zoo thiab yuav tawg, tsuas yog haum rau kev kho kev poob siab. Feem ntau, dej ntws txheej yog siv raws li cov txheej txheem constrained hauv laser kev ua haujlwm laser thiab kev siv khoom lag luam. Nws muaj qhov zoo ntawm kev siv zog muaj zog, kev them nqi qis, kev lag luam yooj yim, thiab tsis xav tau kev hloov. Tsuas yog qee tus me ntawm cov txheej txheem kev txuag nyiaj laser uas tsis siv hluav taws xob, feem ntau lawv yuav tsum muaj lub zog nqus cov khaubncaws sab nraud povtseg. Feem ntau siv Zog nqus cov khaubncaws ua haujlwm yog cov khoom siv nrog cov xim tsis muaj cua sov xws li cov xim dub, txhuas ntawv ci thiab cov kab xev dub. Cov xim dub muaj kev siv zoo thiab tuaj yeem siv rau laser poob siab, tab sis nws tsis yooj yim kom tshem tawm tom qab cov kab xev dub thiab lwm yam yog siv hluav taws xob nqus txheej.
Muaj ntau ntau yam uas cuam tshuam rau cov nyhuv laser poob, thiab lwm yam khoom siv laser, lub zog ua haujlwm ntev dua Txawm li cas los xij, yog tias lub laser pulse dav loj heev, nws yooj yim heev rau ua rau cov khoom hlawv saum npoo av tau cuam tshuam. Tsuas yog xaiv cov txheej txheem tseem ceeb txheej txheej, lub zog nqus txheej thiab Laser Shock tsis raws li cov khoom muaj peev xwm ua tau zoo dua qub tau ua tiav.
Kev sim ua laser laser ntawm cov kev sim ua kom tiav rau cov kev siv ua kom tau zoo rau cov ntawv thov ua haujlwm tseem ceeb Cov kws tshawb fawb hauv tsev thiab txawv teb chaws tau ua ntau txoj kev tshawb fawb ntawm kev ua qauv thiab ua kom zoo ntawm laser shockten. Tam sim no, kev lag luam tau ua tiav zoo nyob rau hauv kev tsom xam cov kev ua kom zoo li Lasing Lebening Lebulation Simulation kev simulation los ntawm intrinsic lim.
Thaum qhov siab -} siab plasma cuam tshuam cov khoom sib txawv, thiab cov lus teb hloov siab heev, uas yog qhov muaj teeb meem ceev ceev. Yog hais tias qhov implicit finite theem algorithm tau siv los daws cov teeb meem no, nws tsis yog yuav tsum tau ntau qhov kev xam thiab kev cia khoom, tab sis kuj muaj teeb meem hauv kev xam sib cav. Nws yog ib qho tsim nyog los siv cov qauv kev tshawb fawb zoo meej rau kev daws teeb meem yoj yoj tsim los ntawm ntshav cuam tshuam. Tshwj xeeb yog siv cov tshuaj ntsuam xyuas thiab kev tshawb xyuas cov txheej txheem kev soj ntsuam zoo ntawm cov khoom ua haujlwm ntawm lub caij poob siab yog ua kom muaj kev cuam tshuam zoo li kev ua kom raug.
Thaum cov tib -}}}}} Txoj kev khiav ceev ntau dua nyob rau hauv ib qho chaw loj, thiab nws siv sijhawm ntau los tau txais cov kev ntxhov siab uas seem ntawm cov hnoos qeev. Ib qho ntxiv, vim muaj ntau yam cuam tshuam ntawm worometry ntawm cov kev ntxhov siab tam sim no nrog cov kev ntxhov siab uas siv cov kev ntxhov siab ntawm cov supercharposition.
Txhawm rau kom muaj kev daws tau ob qho teeb meem no, qee cov kws tshawb nrhiav tau tsim cov lej zauv uas tau tsim rau simulate kev ntxhov siab ntawm laser kev ua kom tawv. Cov qauv no kwv yees tias kev sib zog ntawm kev sib xyaw los ntawm laser kev poob siab nyob rau saum npoo ntawm cov khoom yog insensitive rau cov khoom sib xyaw. Kev simulation cov txheej txheem tsuas yog tsom rau cov quav yas ua los ntawm laser poob siab. Txojlus lim ntawm loj- thaj tsam mult}}} tus taw qhia laser yog siv los tau txais cov kev ntxhov siab zaum kawg thiab kev deformation yas.
Nyob rau hauv xyoo tsis ntev los no, muaj kev cuam tshuam cov kws tshawb fawb hauv tsev thiab txawv teb chaws tau siv cov qauv no rau kev muaj kev ntxhov siab ntawm Laser Sead muaj zog ntxiv ntawm cov sib txawv nyuaj. Kev suav ua haujlwm ntawm qhov qauv sib xyaw no yog txhim kho cov qauv qub nrog cov qauv ib txwm muaj peev xwm ua ntej cov kev ntxhov siab ntawm kev poob siab.
