Simulation ntawm Kub Forging
Tshaj tawm los ntawmAdmin
Kub Forging yog txheej txheem tsim uas yog siv los tsim ntau yam hlau,suav nrog automotive thiab aerospace Cheebtsam.Nws tau nyob ib puag ncig txij li xyoo pua nees nkaum.Txawm li cas los xij, muaj ntau yam uas yuav tsum tau coj mus rau hauv tus account thaum tsim cov txheej txheem kub forging.Cov no suav nrog cov khoom siv forgeability, kub faib thiab cov nyhuv ntawm cov ntawv sau.Ntxiv mus, lub microstructure ntawm forged ib feem yuav tsum raug xam kom raug.Kub forging muaj qhov kub thiab txiasuas ua rau muaj kev hloov pauv tseem ceeb ntawm thaj tsam ntawm qhov chaw ua haujlwm.Ntxiv rau qhov no, txheej txheem forging kuj tuaj yeem ua rau tsim cov oxidized nto.Cov txheej txheem forging feem ntau yog siv los tsim cov khoom nrog 3D geometries complex.Yog li ntawd, qhov tseeb ntawm tus qauv yog qhov tseem ceeb rau kev ua tiav simulation.Feem ntau, peb hom qauv qauv yog siv los simulate tus txheej txheem: FE (Fuzzy EM) cov tswv yim, rov qab taug qab, thiab lub caij kawg.Kub forging yog txheej txheem tsim khoom tseem ceeb rau kev nyab xeeb-tseem ceeb.Qhov no yog vim nws enables forging ntawm hlau qhov chaw nrog siab khiav hauj lwm loads.Txij li thaum qhov kub thiab txias yog qhov siab, nws tuaj yeem pab tsim cov hlau uas yog malleable thiab resistant rau deformation.Muaj ob lub ntsiab ntawm forging: qhib tuag forging thiab tshuab khw forging.Cov nyiaj pub rau forging zoo tuaj yeem nyob ntawm kaum ntawm millimeters mus rau ob peb millimeters.Vim li no, kev tsis sib haum xeeb ntawm kev tuag tuaj yeem ua rau muaj teeb meem loj.Nyob ntawm cov khoom siv forged, ntau hom kev tuag yuav xav tau.Tsis tas li ntawd, kub forging yuav xav tau cov kauj ruam ua haujlwm ntxiv, xws li kev kho cua sov lossis kev ua tiav.Txawm hais tias nws qhov tseem ceeb, kub forging tsis yog qhov tseeb raws li qhov txias forging.Qhov no yog vim qhov thermal expansion ntawm cov khoom thaum lub sij hawm forging txheej txheem tuaj yeem cuam tshuam qhov tseeb ntawm cov khoom tiav.Tsis tas li ntawd, kev siv cov khoom siv hluav taws xob tsis sib xws tuaj yeem ua rau muaj kev hloov pauv loj hauv microstructure ntawm forged feem.Yog li, nws tseem ceeb heev kom paub tseeb tias cov hlau forged muaj qhov yuav tsum tau muaj zog thiab toughness.Txhawm rau simulate txheej txheem forging,Peb txoj kev tsim qauv yooj yim yuav tsum tau siv.Ua ntej, cov txheej txheem finite tuaj yeem siv los simulate cov txheej txheem tsim.Qhov thib ob, txoj kev FE tuaj yeem siv los txiav txim siab qhov kub thiab txias hauv qhov forged.Thaum kawg, cov txheej txheem rov qab tracing qauv tuaj yeem siv los tsim cov txheej txheem kub forging.Txhawm rau xam qhov tseeb qhov kub thiab txias,cov txheej txheem forging yuav tsum tau ua raws li kev tswj hwm.Qhov no yog vim nws yog ib qho tseem ceeb los xav txog cov ntawv sau thiab smoothing ntawm cov npoo ntse.Tsis tas li ntawd, kev siv cov khoom siv tuag tshwj xeeb uas tuaj yeem tiv taus qhov kub thiab txias kuj tau pom zoo.Lwm qhov teeb meem yuav tsum tau xav txog yog qhov kev xaiv ntawm lub tshuab tsim.Xaiv lub tshuab kom raug muaj kev cuam tshuam loj rau qhov kub thiab txias ntawm qhov forged.Thaum kawg, nws yog ib qho tseem ceeb uas yuav tau xav txog kev khaws cia thiab sijhawm thauj mus los.Txhawm rau txiav txim siab qhov tsim nyog forging kub, qhov siab tshaj plaws muaj zog tsim yog siv.Thaum lub sij hawm tus txheej txheem, lub forging tuag yog raug rau siab mechanical thiab tshuaj loads.Nrog rau cov loads no, cov tuag yuav tsum tiv taus ntau yam thermal thiab tshuaj hloov pauv.Ntxiv mus, muaj qhov tseem ceeb residual stresses.
