Thaum ib feem hlau tawm ntawm cov xovxwm, cov txheej txheem tsim khoom nyob deb dhau lawm. Rau cov kws tshaj lij thiab cov neeg tswj xyuas kev tswj xyuas zoo, lub sijhawm tam sim tom qab stamping yog qhov tseem ceeb. Thaum lub sijhawm no, kev ntxhov siab sab hauv- feem ntau tsim los ntawm kev ua haujlwm txias, khoov, lossis tho- tuaj yeem ua rau "kev tawm tsam qeeb" tsis ua haujlwm xws li warping, dimensional shifts, lossis stress corrosion cracking. Yog tias koj cov khoom ua tsis tiav thaum lub sijhawm sib dhos tom ntej lossis tom qab lawv ncav cuag tus neeg siv kawg, koj tsis saib qhov yuam kev stamping; koj tab tom saib qhov teeb meem metallurgical stability.
Qhov cuam tshuam zais ntawm kev ntxhov siab
Txhua lub sij hawm ib daim ntawv hlau yog tsim, crystalline qauv ntawm cov khoom raug thawb mus rau nws elastic txwv. Txawm hais tias qhov seem yuav tshwm sim zoo meej thaum tawm hauv qhov tuag, nws tau zoo "loaded" nrog lub zog sab hauv. Yog tias lub zog no tsis tau tswj hwm, nws tuaj yeem ua rau qhov chaw maj mam nkag mus rau hauv cov duab tsis raug raws sijhawm. Qhov no tshwj xeeb tshaj yog nyob rau hauv siab -lub zog alloys siv nyob rau hauv cov khoom siv tsheb. Yog tias koj pom koj cov khoom ua tsis tau "go/no-go" ntsuas ntsuas lub lis piam tom qab kev tsim khoom, koj tuaj yeem cuam tshuam nrog cov kev ntxhov siab seem.
Tswj kev ruaj ntseg nrog kev ntxhov siab -Nyob rau hauv kev ntxhov siab
Rau qhov chaw uas yuav tsum tau muaj qhov ntev ntev, qhov kev daws teeb meem zoo tshaj plaws yog kev tswj xyuas qhov kub thiab txias lub voj voog hu ua kev ntxhov siab -relief annealing. Los ntawm cua sov cov khoom mus rau qhov kub thiab txias hauv qab nws qhov kev hloov pauv thiab tuav nws nyob ntawd, koj tso cai rau cov hlau nplaum kom rov kho nws tus kheej, ua rau cov kev ntxhov siab tsis zoo yam tsis hloov cov khoom hardness lossis lub zog. Cov txheej txheem no yog qhov txawv ntawm qhov "zoo" thiab "precision-engineered" tivthaiv uas yuav tuav nws cov duab rau lub neej ntawm cov khoom. Yog tias koj cov neeg siv khoom nyob hauv aerospace lossis siab - cov kev lag luam muaj tseeb, muab kev ntxhov siab- nyem raws li ib feem ntawm koj cov saw muaj nuj nqis yog qhov kev sib tw loj.
Predicting Failure Los ntawm Simulation
Tsis txhob tos rau koj qhov chaw kom warp kom paub tias koj cov txheej txheem tsis raug. Niaj hnub nimno CAE (Computer-Aided Engineering) software tuaj yeem kwv yees qhov twg cov kev ntxhov siab nyob hauv yuav sib sau ua ke raws li koj qhov geometry tuag. Ua ntej koj txiav ib daim hlau, simulate cov txheej txheem tsim los txheeb xyuas "cov chaw kub" qhov twg cov txheej txheem nruj yog siab tshaj. Los ntawm kev hloov kho koj cov kab ke los yog qhia txog theem "restrike" hauv qhov tuag, koj tuaj yeem rov faib cov kev ntxhov siab no ua ntej lawv dhau los ua teeb meem. Qhov kev ua haujlwm zoo tshaj plaws no qhia tau hais tias ib theem ntawm kev ua haujlwm tob uas cov khw muag khoom yooj yim tsis tuaj yeem sib xws.
Kev ntsuam xyuas kev ncaj ncees
Yog tias koj xav tias koj cov txheej txheem tam sim no tab tom tsim qhov tsis ruaj khov, ua qhov "time-lapse" qhov ntsuas qhov ntsuas. Ntsuas koj cov khoom tam sim tom qab kev tsim khoom, thiab tom qab ntawd dua tom qab 24, 72, thiab 168 teev. Yog tias qhov loj me me txav mus los, koj muaj qhov tseeb, qhov muaj peev xwm ntxiv rau cov txheej txheem ruaj khov-txhua yam lossis thermal- rau koj qhov kev ua haujlwm. Muab cov ntaub ntawv no rau koj cov neeg siv khoom qhia tias koj tau nqis peev ntau rau hauv lub sijhawm ntev - kev ua tau zoo ntawm lawv cov khoom, es tsis yog tsuas yog ntaus ib qho ntawm cov khoom.
Tso koj lub khw ua tus muab kev daws teeb meem
Thaum sib tw ntawm cov haujlwm nyuaj, hloov koj qhov kev muag khoom. Tsis yog tsuas yog qhia koj lub peev xwm stamping, teeb tsa koj cov kev pabcuam raws li "Tag nrho Cov Qauv Tswj Xyuas." Piav tias koj cov txheej txheem suav nrog physics ntawm hlau deformation, kev tswj cov kev ntxhov siab uas seem, thiab kev ruaj ntseg ntawm qhov ntev - lub sij hawm seem stability.
Cov neeg yuav khoom thoob ntiaj teb niaj hnub tshawb nrhiav cov neeg muag khoom uas nkag siab "yuav ua li cas" thiab "vim li cas" ntawm kev ua tsis tiav, tsis yog "dab tsi." Los ntawm kev tso koj lub khw los ua ib tus khub uas daws cov teeb meem ntawm cov txheej txheem ua ntej lawv tshwm sim, koj nce koj cov xwm txheej los ntawm tus neeg muag khoom thib ob mus rau kev sib koom ua lag luam. Yog tias koj xav kom muaj kev ruaj ntseg siab dua - cov ntawv cog lus, nres muag cov hlau stamped thiab pib muag qhov lav tias koj cov khoom yuav tsis poob, warp, los yog tawg -txawm tias nyob rau hauv cov kev xav tau kev pab cuam tshaj plaws.
