Cov khoom siv hluav taws xob sib txuas thiab cov qauv sib xyaw ua ke yog ob txoj hauv kev uas siv los ntsuas hauv cov txheej txheem ntawm cov khoom siv cua sov thiab kev ntsuas kev ua haujlwm. Ob leeg ua lub luag haujlwm tseem ceeb hauv kev ntsuam xyuas cov khoom siv hluav taws xob ntawm cov khoom siv, tab sis lawv sib txawv hauv daim ntawv, lub hom phiaj, thiab kev sawv cev ntawm cov txiaj ntsig kev xeem. Hauv qab no yog cov lus piav qhia ntxaws ntxaws ntawm cov khoom siv hluav taws xob sib txuas thiab cov qauv sib xyaw, nrog rau kev txheeb xyuas qhov sib txawv ntawm lawv.
Rauv-Attached Specimens
Cov khoom siv hluav taws xob sib txuas yog xa mus rau cov qauv ywj pheej uas muab tso rau hauv qhov cub kho cua sov nrog rau cov khoom siv los kuaj, ua raws li cov txheej txheem kev kho cua sov. Cov qauv no feem ntau yog npaj raws li cov duab thiab qhov loj ntawm cov khoom yuav tsum tau kuaj, nrog cov khoom zoo sib xws thiab cov txheej txheem ua haujlwm. Lub hom phiaj tseem ceeb ntawm cov khoom siv hluav taws xob txuas yog simulate cov xwm txheej uas cov khoom tau ntsib thaum lub sijhawm tsim khoom tiag tiag thiab ntsuas cov khoom siv kho tshuab, xws li hardness, tensile lub zog, thiab lub zog tawm los, raws li cov txheej txheem kho cua sov tshwj xeeb.
Qhov kom zoo dua ntawm cov khoom siv hluav taws xob sib txuas yog nyob rau hauv lawv lub peev xwm los cuam tshuam cov khoom ua tau zoo raws li cov khoom siv tiag tiag, vim lawv tau txais cov txheej txheem kev kho cua sov tib yam li cov khoom raug kuaj. Tsis tas li ntawd, txij li cov khoom siv hluav taws xob txuas nrog cov khoom siv hluav taws xob tsis muaj kev ywj pheej, lawv tuaj yeem zam qhov tsis raug uas yuav tshwm sim thaum kuaj vim qhov hloov pauv ntawm cov khoom geometry lossis loj.
Integral Specimens
Integral specimens txawv ntawm qhov cub-txuas cov qauv uas lawv txuas ncaj qha rau cov khoom raug kuaj. Cov qauv no feem ntau yog machined ncaj qha los ntawm qhov khoob los yog forging ntawm cov khoom. Integral specimens tsis xav tau kev npaj cais vim lawv yog ib feem ntawm cov khoom nws tus kheej thiab tuaj yeem ua tiav kev tsim khoom thiab kev kho cua sov ua ke nrog cov khoom siv. Yog li ntawd, cov khoom siv kho tshuab tau cuam tshuam los ntawm cov qauv sib xyaw ua ke zoo sib xws nrog cov khoom siv nws tus kheej, tshwj xeeb tshaj yog nyob rau hauv cov ntsiab lus ntawm tag nrho kev ncaj ncees thiab sib xws ntawm cov khoom.
Ib qho txiaj ntsig tseem ceeb ntawm cov qauv ib txwm yog lawv lub peev xwm los cuam tshuam qhov kev ua tau zoo ntawm cov khoom, tshwj xeeb tshaj yog nyob rau hauv complex-shaped lossis loj workpieces. Txij li cov qauv ib txwm txuas ncaj qha rau cov khoom siv, lawv tuaj yeem ua kom pom qhov ua tau zoo ntawm qhov chaw tshwj xeeb lossis qhov chaw ntawm cov khoom. Txawm li cas los xij, cov qauv sib xyaw kuj tseem muaj qee qhov tsis zoo, xws li qhov tsis raug ntawm qhov kev xeem tau tshwm sim vim yog deformation los yog kev ntxhov siab thaum lub sij hawm sim, vim lawv tseem txuas nrog cov khoom siv.
Cov khoom siv hluav taws xob sib txuas thiab cov khoom siv sib txuas ua haujlwm sib txawv hauv kev kho cua sov thiab kev ntsuas kev ua haujlwm ntawm cov khoom. Cov khoom siv hluav taws xob sib txuas, tau npaj los ntawm nws tus kheej, simulate cov khoom ua tau zoo nyob rau hauv kev kho cua sov, whereas ib qho piv txwv, los ntawm kev sib txuas ncaj qha rau cov khoom, zoo dua qhov kev ua tau zoo ntawm cov khoom. Hauv kev siv tswv yim, kev xaiv ntawm ob hom qauv no yuav tsum yog raws li cov kev xav tau tshwj xeeb, cov yam ntxwv ntawm cov khoom siv, thiab cov txheej txheem yuav tsum tau ua. Cov khoom siv hluav taws xob sib txuas yog tsim nyog rau kev siv cov txheej txheem kho cua sov thiab simulating cov khoom ua tau zoo, thaum cov qauv ib txwm tsim nyog rau kev ntsuam xyuas tag nrho cov kev ua tau zoo ntawm cov khoom siv lossis cov khoom loj. Los ntawm kev ua tib zoo xaiv thiab siv ob hom qauv no, nws muaj peev xwm los ntsuas cov khoom siv kho tshuab ntawm cov khoom thiab xyuas kom zoo thiab kev ntseeg siab ntawm cov khoom.
