Lub kaus mom snowmobile tau nthuav tawm ntawm lub caij ntuj no Olympics yog tsim los ntawm pab pawg Dongguan Institute of Technology. Nws tsis yog tsuas yog kev nyab xeeb, thiab sib dua, tab sis kuj kho.
Snowmobiles yog ib qho ntawm cov xwm txheej ceev tshaj plaws thiab lom zem tshaj plaws hauv lub caij ntuj no Olympics. Qhov tshwm sim yog feem ntau nyob rau hauv milliseconds, yog li cov hardware yuav tsum nruj heev. Cov pab pawg tshawb fawb thiab kev txhim kho cov kaus mom snowmobile coj los ntawm Li Nan, tus kws tshaj lij ntawm Tsev Kawm Ntawv Kev Kawm (Normal College) ntawm Dongguan University of Technology, tau koom nrog kev tshawb fawb thiab kev tsim cov kaus mom snowmobile, uas tau siv rau hauv kev cob qhia ntawm lub teb chaws pab neeg lub caij ntuj no Olympics. Pab neeg no siv 3D thim rov qab qauv thiab lattice qauv 3D luam ntawv thev naus laus zis thiab sau cov ntaub ntawv ncaws pob los kho cov kaus mom snowmobile ib-rau-ib kom tau raws li qhov xav tau tiag tiag ntawm txhua tus neeg ncaws pob. Qhov no ua tib zoo "ntse" kaus mom hlau muaj cov yam ntxwv ntawm tus kheej, txo qhov hnyav, kev nyab xeeb, thiab lwm yam.
Kev xaiv cov khoom siv thiab cov qauv
Raws li qhov yuav tsum tau muaj, lub kaus mom hlau yuav tsum muaj tag nrho cov khoom siv thiab cov khoom siv los ua Tuam Tshoj tus kheej.
Hauv kev siv cov ntaub ntawv, txheej txheej ntawm tus kheej tsim lub kaus mom snowmobile no yog ua los ntawm Tuam Tshoj Aerospace T800 carbon fiber cov khoom siv nrog lub zog siab thiab kev ua haujlwm zoo tiv thaiv kev sib tsoo. T800 carbon fiber yog ib yam tshiab ntawm high-strength, high-modulus fiber ntau nrog cov ntsiab lus ntawm ntau tshaj 95 feem pua. Vim tias cov khoom tau raug carbonized thiab graphitized, nws muaj qhov zoo ntawm qhov ntom ntom thiab siab zog. Raws li cov ntaub ntawv tseem ceeb, qhov ceev ntawm cov khoom siv fiber ntau yog qis dua li ntawm aluminium, tab sis lub zog yog ntau dua li cov hlau.
Sab hauv cov khoom tsis txheej ntawm lub kaus mom hlau txais yuav 3D luam ntawv lattice qauv. Lub microstructure ntawm cov khoom ua si lub luag haujlwm loj hauv nws lub peev xwm los nqus kev poob siab. Nws tau tshaj tawm tias pab pawg tshawb fawb tau dhau los ntawm kaum tawm txhiab qhov kev suav los ntawm kev xaiv cov lattice mus rau qhov sib piv ntawm lub kaus mom hlau thiab cov khoom siv, thiab thaum kawg txiav txim siab qhov zoo tshaj plaws lattice qauv thiab Khoom siv. Siv 3D luam ntawv (SLS thev naus laus zis) thiab TPU cov ntaub ntawv hmoov, cov txheej txheem lattice ntawm lub kaus mom hlau tsis muaj txheej txheem yog tsim thiab tsim, uas zoo tshaj rau cov khoom siv EPS ua npuas ncauj, thiab nws cov kev cuam tshuam kev cuam tshuam tau txhim kho li ntawm 40 feem pua, uas tuaj yeem tiv taus. lub kaus mom hlau thaum nws ntsib kev sib tsoo. ntau yam cuam tshuam quab yuam thiab zoo dua tiv thaiv tus neeg ncaws pob lub taub hau.
Nws tau nkag siab tias lub kaus mom hlau ua los ntawm carbon fiber thiab TPU lattice qauv hnyav tsuas yog li 1.1 kg, uas yog 500 grams tsawg dua li cov kaus mom hlau siv los ntawm pab pawg hauv tebchaws ua ntej, txo qhov hnyav ntawm cov neeg ncaws pob. Tam sim no, lub kaus mom snowmobile no tau dhau GB thiab ECE daim ntawv pov thawj ua tau raws li qhov yuav tsum tau muaj ntawm FIS kev sib tw kaus mom hlau, thiab tau xa mus rau pab pawg neeg daus hauv tebchaws.
3D luam ntawv lattice buffer qauv siv TPU
Cov qauv lattice feem ntau yog hais txog qhov chaw truss uas muaj cov pas nrig, daim hlau, thiab lwm yam micro-cov ntsiab lus uas tau rov ua dua raws li qee txoj cai. Nws muaj cov yam ntxwv ntawm cov tuab tsawg, thaj av loj tshwj xeeb, thiab cov kws kho hauv cov khoom siv zoo ib yam. Sandwich qauv nrog nws raws li cov khoom tseem ceeb ua rau cov yas loj heev deformation vim lub zog tsis ruaj khov ntawm cov qauv nyob rau hauv kev cuam tshuam load thiab hloov nws mus rau hauv lub zog hluav taws xob, uas tuaj yeem nqus tau feem ntau ntawm lub zog cuam tshuam, yog li nws muaj qhov tsis zoo ntawm lub zog nqus thiab cuam tshuam. tsis kam. , thiaj li ua si ib qho kev tiv thaiv.
3D luam ntawv muaj qhov zoo dua qub hauv kev tsim cov kab lattice, uas tuaj yeem ua tiav yuav luag txhua qhov tsis muaj tseeb, qhov tsis muaj feem, tsis muaj duab, qhov loj me, qhov pore faib, thiab kev sib txuas. Raws li qhov no, 3D luam ntawv lattice qauv tuaj yeem ua cov cuab yeej tiv thaiv kev ua kis las, uas coj lub zog tshiab rau kev hloov pauv thiab hloov kho cov kaus mom hlau, armor, thiab lwm yam khoom siv tiv thaiv.
Tsis tas li ntawd, cov khoom siv ntawm kev tsim khoom txiav txim siab cov khoom thiab kev siv ntawm cov lattice. TPU muaj peev xwm ua tau zoo heev, cuam tshuam tsis kam, thiab kev ua haujlwm poob siab, thiab tuav lub cev zoo xws li elasticity thiab yooj txawm nyob ntawm -35 degree . Nws yog dav siv hauv kev kho mob thiab kev noj qab haus huv, khoom siv hluav taws xob, kev lag luam, kev ua kis las, thiab lwm yam. Tib lub sijhawm, TPU tseem yog cov khoom siv elastomer tseem ceeb rau 3D luam ntawv.
Raws li cov ntsiab lus saum toj no, pab pawg snowmobile kaus mom hlau tau xaiv TPU ua cov khoom siv lattice.
"Science thiab Technology Winter Olympics" yog ib qho tseem ceeb ntawm Beijing Winter Olympics. Raws li kev taw qhia ntawm lub tswvyim ntawm "Science thiab Technology Olympics", suav tsis txheeb cov neeg ua haujlwm tshawb fawb thiab thev naus laus zis tau pib "Olympic Science thiab Technology Long-distance Run". Ib theem rau kev cia siab rau tus kheej thiab kev cia siab rau tus kheej ntawm kab rov tav tshuab. Raws li cov thev naus laus zis tshiab uas tau tsim kho sai hauv xyoo tas los no, 3D luam ntawv kuj tau ua lub luag haujlwm tseem ceeb hauv kev npaj rau lub caij ntuj no Olympics.
