Ib tus neeg siv khoom taug kev nrog lub stamped -thiab-welded steel roj teeb- pob bracket. Nws yog tsim los ntawm tsib qhov sib cais uas yuav tsum tau welded ua ke. Lub pob twb hnyav, ntau yam yog kev txom nyem, thiab txhua kilogram ntxiv nqi zog. Cov lus nug yooj yim: peb puas tuaj yeem khaws lub zog thiab txiav qhov hnyav tib lub sijhawm? Cov lus teb yog yog. Los ntawm kev sib txuas topology optimization nrogAluminium Alloy 3D luam ntawv, engineers muaj peev xwm redesign lub bracket kom cov khoom nyob twj ywm nyob rau hauv tsuas yog qhov chaw uas nws xav tau, ntau qhov chaw ua ib tug, thiab qhov kawg tivthaiv yog ho sib zog.
Vim Li Cas Nyhav Tseem Ceeb Ntau Hauv EV Roj Teeb Pob
Lub roj teeb pob feem ntau yog ib qho hnyav tshaj plaws hauv lub tsheb fais fab, feem ntau suav txog 20-25% ntawm tag nrho qhov hnyav. Cov huab hwm coj ntxiv tsub kom dov tsis kam, xav tau ntau lub zog thaum lub sij hawm acceleration, thiab txo cov kev ua tau zoo ntawm regenerative braking. Raws li txoj cai kev lag luam ntxhib ntawm tus ntiv tes xoo, txhua 100 kg ntawm qhov hnyav tau khaws cia tuaj yeem ntxiv ib ncig ntawm 15-17 km ntawm qhov tiag - ntiaj teb ntau yam, lossis kwv yees li 5-6% kev txhim kho rau 10% txo cov tsheb hnyav.
Brackets thiab cov qauv kev txhawb nqa yog lub hom phiaj zoo heev rau kev sib sib zog nqus. Muaj ntau ntawm lawv nyob rau hauv ib tug raug pob, lawv yog structurally ywj siab, thiab lawv tsis tas yuav nqa tag nrho cov poob loads ntawm lub ntsiab enclosure. Txo lawv cov huab hwm coj thiaj li muab cov txiaj ntsig ntsuas tau yam tsis muaj kev cuam tshuam cov qauv kev nyab xeeb thawj.
Aluminium Alloy 3D Printing yog dab tsi, hauv Lus Askiv?
Hauv cov ntsiab lus yooj yim, Aluminium Alloy 3D Printing tsim ib feem los ntawm kev nthuav tawm cov txheej nyias ntawm cov hmoov txhuas thiab yaj lawv nrog lub laser, ib txheej ib zaug, kom txog rau thaum tag nrho cov geometry tiav. Cov txheej txheem tseem hu ua laser hmoov - txaj fusion. Vim tias cov khoom siv ntxiv tsuas yog qhov tsim nyog yuav tsum tau ua, txoj hauv kev hauv lattices, cov duab organic thiab sib sau ua ke tuaj yeem ua tau.
Vim li cas AlSi10Mg yog qhov kev xaiv ntau tshaj plaws
AlSi10Mg 3D Printed Parts dominate automotive applications. Cov alloy muaj qhov sib npaug zoo ntawm lub zog, castability -zoo li luam tawm, thiab qhov ntom ntom ntom (kwv yees li 2.67 g / cm³). Tom qab kev kho cua sov kom zoo nws muab lub zog tensile nyob rau hauv 300-350 MPa ntau yam nrog usable ductility, ua rau nws haum rau structural brackets.
Aluminium vs. steel vs. cam khwb cia txhuas
Ceev: AlSi10Mg ≈ 2.67 g/cm³|Hlau ≈ 7.8 g / cm³|Cam khwb cia txhuas zoo ib yam li AlSi10Mg
Lub zog tshwj xeeb: 3D- luam tawm AlSi10Mg yog kev sib tw nrog ntau cov hlau ntawm qhov hnyav-rau- qhov hnyav
Tsim kev ywj pheej: deb tshaj qhov casting lossis stamping, tso cai rau topology- optimized shapes uas ib txwm siv tsis tau
5 Txoj Kev 3D Printing Ua Rau Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob
Topology optimization
Software tshem tawm cov khoom los ntawm qhov tsawg- thaj tsam kev ntxhov siab thiab tso nws tsuas yog qhov chaw thauj khoom mus ncig. Nyob rau hauv cov ntaub ntawv luam tawm no ib leeg tau txiav bracket loj los ntawm 30-50% thaum ua kom muaj kev ntxhov siab nyob rau hauv kev txwv.
Lattice thiab hollow structures
Internal lattices los yog hollow seem hloov cov khoom seem. Ib feem ua kom nruj qhov xav tau tab sis tso cov khoom tsis tsim nyog. Qhov no yog tsis yooj yim sua nrog pa stamping.
Kev sib sau ua ke
Tsib daim ntawv stamped uas ib zaug yuav tsum tau vuam lossis bolting tuaj yeem dhau los ua ib qho kev luam tawm. Cov pob qij txha tsawg txhais tau tias tsawg dua los ntawm cov fasteners, weld hlaws thiab overlapping flanges.
Cov phab ntsa nyias nyias tsis poob qhov tawv
Vim tias cov khoom faib tau ua kom zoo dua qub, phab ntsa tuab tuaj yeem txo qis hauv - chaw thau khoom thaum cov ntu tseem ceeb tseem muaj zog. Zuag qhia tag nrho cov tawv nqaij yog khaws cia los yog txawm txhim kho.
Tsawg fasteners, tsawg sib dhos
Tshem tawm bolts, txiv ntseej thiab vuam tshem tawm ob qho tib si lawv qhov hnyav thiab cov haujlwm thib ob uas xav tau los txhim kho lawv. Kev sib dhos zaum kawg yog sib dua thiab yooj yim dua.
Cov tsib levers no ua haujlwm ua ke. Thaum ua ntawv thov rau Lightweight EV Battery Pack Brackets, cov nyhuv ua ke tsis tu ncua muab 20-40% qhov hnyav txo piv nrog cov qauv tsim los yog welded.
Qhov Kev Tshawb Fawb Hais tias: Tus lej tiag tiag ntawm Kev Txuag Nyhav
Tshaj tawm cov kev tshawb fawb thiab cov xwm txheej hauv kev lag luam tsis tu ncua qhia ob - lej nyiaj txuag. Ib tug phooj ywg- tshuaj xyuas topology-optimized roj teeb bracket ua tiav 49% loj txo thaum ntsib lub zog thiab kev nyab xeeb-factor hom phiaj. Lwm lub tsheb aluminium chassis tivthaiv ua los ntawm loj- hom ntawv hlau luam ntawv xa ntau dua 30% qhov hnyav txo ua ke nrog qhov nce ntxiv ntawm qhov torsional nruj. Suav kev lag luam piv txwv ntawm AlSi10Mg roj teeb txhawb kev tshaj tawm 25% qhov hnyav txiav thiab sib txuam ntau qhov nce ntawm ob peb mais.
Puas yog 3D luam ntawv txhuas muaj zog txaus?
Tau-thaum tus qauv tsim tau raug lees paub. Raws li - ua AlSi10Mg tuaj yeem ncav cuag 400-460 MPa tensile zog; Thaum tshav kub kub- cov khoom siv kho mob pauv qee lub zog rau kev txhim kho ductility thiab seem - kev ntxhov siab. Kev qaug zog, kev co thiab kev sib tsoo yuav tsum tau tshawb xyuas los ntawm kev simulation thiab kev sim lub cev, raws nraim li nrog rau lwm yam khoom siv. Thaum cov kev xeem no dhau lawm,Aluminium Alloy 3D luam ntawvua tau raws li automotive durability kev cia siab.
Case Study: Yuav Ua Li Cas Sunhingstones Txo Qhov Nyhav Bracket
Ib tus neeg muag khoom nyob sab Europe EV xav tau tsev neeg lub roj teeb - pob khoom txhawb nqa. Tus tsim thawj siv cov khoom siv hlau stamped uas tau welded rau hauv sub- sib dhos. Qhov hnyav yog siab, lub sij hawm sib dhos yog ntev, thiab cov qauv kev hloov pauv yuav tsum tau siv cov cuab yeej tshiab.
Sunhingstones redesigned lub brackets siv topology optimization thiab luam lawv nyob rau hauv AlSi10Mg. Ntau daim tau muab sib sau ua ke rau hauv ib qho khoom, cov lattices sab hauv tau qhia nyob rau hauv tsis yog - thaj chaw tseem ceeb, thiab tag nrho cov geometry tau ua kom zoo rau kev luam tawm.
