Kev ua tiav geometric zoo meej hauv cov hlau tsis tshua muaj txheej txheem ncaj qha, tshwj xeeb tshaj yog thaum ua haujlwm nrog cov khoom siv niaj hnub, siab - zog alloys. Ib qho ntawm cov teeb meem nyuaj tshaj plaws rau cov kws tsim khoom tsim khoom yog "caij nplooj ntoos hlav-rov qab"- txoj kev nyiam ntawm cov khoom siv hlau kom rov qab tau nws cov duab qub tom qab lub siab tsim tawm. Qhov elastic rebound no tuaj yeem ua rau muaj kev puas tsuaj rau qhov ntev ntev, ua rau cov khoom sib dhos thiab cov khoom tsis lees paub. Yog tias koj tawm tsam kom khaws koj cov ntaub ntawv nyuaj hauv qhov tshwj xeeb, nws yog lub sijhawm txav dhau qhov yooj yim geometry thiab saib cov physics ntawm cov khoom deformation.
Lub Mechanism ntawm Elastic Recovery
Caij nplooj ntoos hlav-rov qab yog qhov tseem ceeb ntawm kev faib tawm ntawm kev ntxhov siab sab hauv. Thaum lub sij hawm txoj kev mob stroke, cov txheej fibers ntawm cov hlau yog stretched nyob rau hauv nro, thaum lub puab fibers yog compressed. Thaum cov punch thim rov qab, cov kev tsis sib haum xeeb no ib txwm nrhiav kev sib npaug, ua rau qhov hloov pauv. Tus yuam sij rau txo qhov no yog los tswj qhov kev ntxhov siab profilethaumtxoj kev tsim. Es tsis txhob tsuas yog nce qhov tob, xav txog cov tswv yim zoo lihauv qablos yognyiaj npibthaum kawg ntawm kev mob stroke. Los ntawm kev tawm dag zog, lub zog hauv cheeb tsam ntawm lub vojvoog, koj tuaj yeem "teeb" cov hlau, zoo xauv rau hauv cov duab uas xav tau thiab txo qis lub zog khaws cia uas ua rau rov zoo.
Redesigning Radii kom txo qis Rebound
Lub vojvoog khoov yog qhov hloov pauv muaj zog tshaj plaws hauv koj txoj kev tswj hwm. Lub vojvoog nruj dua ua rau cov yas deformation ntau dua li elastic deformation, uas ua rau txo lub caij nplooj ntoos hlav - rov qab muaj peev xwm. Txawm li cas los xij, qhov no yuav tsum sib npaug tiv thaiv cov khoom siv ductility; Yog hais tias lub vojvoog ntse dhau, koj yuav ua rau micro- tawg los yog thinning ntau dhau. Thaum lub sij hawm prototyping theem, siv simulation software los ntsuas qhov "threshold" vojvoog rau koj cov alloy tshwj xeeb. Qee zaum, qhov txo qis ntawm 0.5mm hauv koj lub vojvoog khoov tuaj yeem yog qhov sib txawv ntawm ib feem uas rov qab los ntawm kev ua siab ntev thiab ib qho uas tuav nws cov duab zoo kawg nkaus.
Ua raws li cov tswv yim them nqi zog
Thaum phau ntawv hloov kho rau qhov tuag poob, nws yuav yog lub sijhawm los xav txogtshaj - dabtsi yog khoov. Txoj hauv kev no xav tias qee qhov nyiaj ntawm lub caij nplooj ntoos hlav-rov qab yog qhov kev zam, yog li qhov tuag yog txhob txwm tsim nrog "dhau-paj" geometry. Ib feem yog tsim me ntsis dhau los ntawm nws lub kaum ntse ntse kom thaum nws rov qab los, nws tsaws raws nraim ntawm tus qauv tsim. Txawm hais tias qhov no yuav tsum muaj ntau qhov kev tuag geometry thiab ntsuas qhov tseeb thaum lub sijhawm sim, nws feem ntau yog txoj hauv kev ntseeg siab tshaj plaws kom ua tiav qhov kev ruaj ntseg nyob rau hauv siab - ntim khiav. Tsim "daim ntawv qhia kev them nyiaj" no yog qhov siab tshaj - tus nqi txuj ci- ib qho uas koj tuaj yeem hais txog qhov muaj peev xwm ua haujlwm thaum muab koj cov kev pabcuam rau cov neeg siv khoom uas xav tau qhov tseeb heev.
Lub luag haujlwm ntawm cov khoom sib xws
Yog tias koj pom cov txiaj ntsig tsis zoo uas ib pawg ntawm cov khoom ua tau raws li qhov ua siab ntev thiab qhov ua tsis tiav tom ntej, qhov teeb meem yuav tsis yog koj qhov tuag -nws yog cov khoom siv. Kev hloov pauv hauv cov tshuaj muaj pes tsawg leeg, cov qauv nplej, lossis cov kev taw qhia dov ntawm cov hlau tuaj yeem hloov kho nws lub zog tawm los thiab, yog li ntawd, nws lub caij nplooj ntoos hlav- rov qab yam ntxwv. Yog tias koj tseem tsis tau, xyuas kom meej tias koj cov txheej txheem yuav khoom suav nrog kev txheeb xyuas cov khoom sivr-tus nqi (plastic strain ratio)thiabn-tus nqi (strain hardening exponent). Los ntawm standardizing koj cov khoom siv raw khoom, koj tshem tawm "wildcard" uas feem ntau ua rau cov txiaj ntsig tsis sib haum.
Tsim Koj tus kheej ua tus kws tshaj lij Precision
Kev hais txog caij nplooj ntoos hlav- rov qab yog hais txog ntau tshaj li kho qhov tsis zoo; nws yog hais txog kev ua kom pom kev nkag siab zoo ntawm mechanical engineering. Thaum koj koom nrog cov neeg siv khoom uas ntxhov siab los ntawm qhov tsis txaus ntseeg, tsis txhob cog lus tias "kev sim ntau ntxiv." Taug kev lawv los ntawm koj cov txheej txheem: yuav ua li cas koj xam cov kev ntxhov siab sab hauv, koj kho koj lub radii li cas, thiab seb koj them nyiaj li cas rau cov khoom sib txawv. Qhov no theem ntawm kev transparency yog incredibly tsawg nyob rau hauv daim ntawv cog lus tsim chaw. Nws hloov pauv kev sib tham los ntawm tus nqi -ib - ib feem ntawm kev sib tham mus rau kev sib koom ua ke los ntawm kev txawj ntse. Los ntawm kev ua pov thawj tias koj tuaj yeem paub qhov "tsis paub txog" ntawm kev tsim hlau, koj tso koj lub tuam txhab ua tus mus- rau tus kws tshaj lij rau cov haujlwm nyuaj tshaj plaws thiab muaj txiaj ntsig hauv kev lag luam.
