Casting ntawm cov khoom hlau muaj cov txheej txheem ntawm kev tsim cov txheej txheem uas yuav tsum tau ua kom raug thiab tswj tau. Tsis yog ua cov txheej txheem tsim los ntawm kev sib tsoo-thiab-kev sim mus kom ze, simulations tuaj yeem khiav ua ntej casting yog ua tiav hauv qhov chaw tsim khoom. Cov kev simulation no tso cai rau ua qauv, txheeb xyuas, thiab siv tau tag nrho cov txheej txheem casting nrog rau kev kwv yees ntawm qhov tsis xws luag hauv cov khoom cam khwb cia. Txoj kev tshawb no yog ua raws li kev tsim cov khoom siv kho mob uas siv cov pwm tsim qauv, thiab kuj siv simulation. Lub Computer-Aided Design (CAD) qauv ntawm cov casting yog tsim nyob rau hauv SOLIDWORKS thiab simulated siv MAGMASoft. Cov txiaj ntsig tau txais yog qhov kub thiab txias hauv pwm tom qab pouring, solidification sequence, thiab casting defects xws li porosity thiab hotspots. Kev sib raug zoo ntawm kev sim thiab simulation cov txiaj ntsig tau lees paub cov qauv kev noj qab haus huv txaus los ua kom zoo dua cov pwm los ntawm kev simulations. Lub optimized pwm tsim kiag li tshem tawm cov hotspot thiab txo porosity uas yog nyob rau hauv lub machining pub ntawm cov khoom kawg. Txawm li cas los xij, cov txiaj ntsig casting raug txo los ntawm 6% los ntawm kev ntxiv ib qho ua tib zoo xaiv riser hauv kev tsim pwm zoo. Nws tuaj yeem txiav txim siab tias kev simulations yog qhov tsim nyog hauv kev tsim cov txheej txheem casting, kwv yees qhov tsis xws luag, thiab hloov kho cov qauv tsim siv cov txheej txheem kev ua kom zoo tshaj plaws muaj nyob rau hauv cov txheej txheem casting simulation software siab heev.
