Yuav ua li cas tshem tawm cov qauv kev txhawb nqa sab hauv hauv kev tshaj tawm - ua tiav?

Ib, Txhim kho cov qauv kev txhawb nqa: mus los ntawm "kev tshem tawm passive" mus rau "kev tiv thaiv nquag"
1. Txoj kev ntse los npaj kev txhawb nqa
Daim phiaj lossis kab qauv tsim muaj nyob rau hauv cov txheej txheem kev txhawb nqa ib txwm muaj, txawm hais tias lawv tuaj yeem tso cov hmoov seem thiab ua phem rau saum npoo. Cov qauv tsim niaj hnub pab ua kom zoo tshaj plaws layouts nrog software algorithms, xws li:
Kev them nyiaj yug kab pheeb ces kaum: A 45℃kab pheeb ces kaum kev txhawb nqa yog siv los txuas cov khoom thiab luam ntawv platform hauv cov kev tsim kho nyuaj xws li cov kav dej. Qhov no txo ​​qis tus naj npawb ntawm cov ntsiab lus tiv tauj thiab ua rau kev tshaj tawm - ua haujlwm yooj yim dua.
Fracture point design: Ntxiv cov xuab moos lossis cov hniav -zoo li tus yam ntxwv ntawm kev sib txuas ntawm cov kev txhawb nqa thiab cov ntu los tsim "kev tswj tau tawg" los ntawm ua ntej- teeb tsa cov ntsiab lus tsis muaj zog. Qhov no nres qhov kev nyuaj siab ntawm qhov chaw uas tuaj yeem tshwm sim nrog kev txiav tsis tu ncua.
Kev them nyiaj yug rau regionalization: Siv software los ua kom thaj tsam ntawm qhov kev txhawb nqa loj dua thiab tsom mus rau thaj chaw tseem ceeb tsawg (xws li dav hlau es tsis txhob ntawm qhov chaw), uas ua rau muaj kev cuam tshuam ntawm qhov chaw ua haujlwm tsawg dua.
2. Lub tswv yim rau kev sib txawv ntawm cov khoom
Lub tshuab hluav taws xob tshem tawm hluav taws xob tawm tswv yim los ntawm Arizona State University ua tiav "tsis yog- tshem tawm kev puas tsuaj" los ntawm kev xaiv corroding cov ntaub ntawv txhawb nqa (xws li carbon steel) thaum khaws lub cev tseem ceeb ntawm cov khoom (xws li stainless hlau). Lub tshuab no yuav tsum ua kom tiav cov txheej txheem tom ntej:
Qhov sib txawv ntawm electrochemical muaj peev xwm ntawm cov khoom txhawb nqa thiab cov khoom siv yuav tsum muaj ntau dua 0.2V. Cov tshuaj electrolyte yuav tsum muaj kev xaiv siab (piv txwv li, qhov corrosion ntawm carbon steel hauv nitric acid + oxygen system yuav tsum yog ntau tshaj 100 npaug ntawm cov hlau tsis muaj steel). Lub sijhawm tshuaj tiv thaiv yuav tsum tau tswj kom tsis txhob muaj corrosion ntau dhau.
2, Txoj kev qub ntawm kev tshem tawm cov khoom yog nrhiav qhov sib npaug ntawm cov khoom siv kho tshuab thiab kev kho tshuaj.
1. Tshuab rau kev tshem tawm cov khoom siv tshuab
Cov cuab yeej tes xws li pliers, txiab, thiab cov ntaub ntawv ua haujlwm zoo ntawm kev tsim kho yooj yim, tab sis lawv tuaj yeem khawb qhov chaw ntawm qhov chaw. Piv txwv li, thaum tshem tawm cov kev txhawb nqa ntawm ib lub dav hlau cav hniav, 0.5mm tuab cov khoom seem yuav tsum tau polished los ntawm tes, uas tuaj yeem siv li plaub teev txhua daim.
Band pom thiab xaim txiav: Hluav taws xob xaim xaim txiav (EDM) tuaj yeem cais cov khoom nrog qhov raug siab heev, tab sis nws raug nqi ntau heev. Qhov kev txiav ceev ntawm cov saw saw tau nce mus txog 30%, tab sis lub dav hlau hauv qab yuav tsum tau rov ua dua los kho nws.
Kev kho mob siv sandblasting: Siv siab -siab aluminium oxide sand particles los tsoo saum npoo tuaj yeem tshem tawm ob qho tib si cov khoom seem thiab oxide txheej tib lub sijhawm, tab sis nws kuj tseem tuaj yeem zais qhov tsis raug xws li microcracks.
2. Technology rau tshuaj corrosion
Cov kua qaub, zoo li kev sib xyaw ntawm hydrofluoric acid thiab nitric acid, tuaj yeem ua rau titanium alloy txhawb nqa. Txawm li cas los xij, qhov kub (tsawg dua 40 degrees Celsius) thiab lub sijhawm (tsawg dua 15 feeb) yuav tsum tau ua tib zoo tswj, lossis cov khoom yuav dhau los ua rougher ntawm qhov chaw.
Kev daws nrog lub hauv paus: Sodium hydroxide tov yog qhov zoo rau txhuas-raws li kev txhawb nqa, tab sis nws yuav tsum tau ua kom tsis zoo tom qab ntawd kom tsis txhob muaj hydrogen embrittlement.
Electrochemical polishing: Cov txheej txheem no tshem tawm cov khoom seem los ntawm anodic dissolution thiab ua rau saum npoo smoother (Ra tus nqi tuaj yeem txo qis dua 0.2 μm), tab sis cov khoom siv kim heev.
3, Fusion: Kev daws teeb meem siv neeg hlau thiab AI
1. Cov neeg hlau los pab lub kaw lus
Solukon hauv lub teb chaws Yelemees ua SFM-AT800 system, uas siv cov thev naus laus zis hauv qab no los ua kom tshem tawm:
Tswj kev sib txuas ntawm ntau yam -axis txuas: 6-axis neeg hlau tau txiav lub taub hau, lub kaum sab xis grinders, thiab lwm yam khoom siv uas cia nws ua haujlwm nrog cov txheej txheem sab hauv nyuaj.
Hloov lub zog tawm tswv yim: tiag - lub sij hawm saib xyuas ntawm txiav quab yuam (<5N) and automatic adjustment of feed speed to avoid damage to the part;
Module rau cov hmoov rov ua dua: Kev sib xyaw tsis zoo lub tshuab nqus tsev nqus tsev vacuum uas rov ua dua 98% ntawm cov khoom nws khaws, uas txo cov pov tseg.
2. AI- tau tsav cov txheej txheem txhim kho
Lub Rivelin Robotics NetShape system hauv UK siv tshuab kev kawm algorithms:
Kev kwv yees tsis raug: Siv cov ntaub ntawv dhau los los tsim cov qauv kev faib khoom seem kom koj tuaj yeem npaj txoj hauv kev zoo tshaj plaws los tshem tawm qhov tsis xws luag ua ntej;
Kev hloov kho cov cuab yeej: Hloov cov kev txiav (ceev, pub tus nqi) cia li nyob ntawm qhov hardness ntawm cov khoom (piv txwv li, Inconel 718 vs. aluminium alloy);
Zoo kaw- voj tswj: 3D scanning tuaj yeem qhia koj tias qhov chaw ntxhib npaum li cas hauv lub sijhawm, thiab koj tuaj yeem hloov lub sijhawm polishing ntawm kev mus.
4, Cov thev naus laus zis tshiab: los ntawm "tshem tawm" mus rau "tsis txhawb nqa" ntau lawm
1. Tsim rau topology optimization
Siv software zoo li Altair OptiStruct tuaj yeem pab ua kom cov qauv muaj zog dua thaum txo cov nyiaj them yug uas lawv xav tau. Topology optimization, piv txwv li, txiav qhov kev txhawb nqa ntim ntawm ib qho kev muab satellite bracket los ntawm 60% thiab lub sijhawm nws siv los ua nws los ntawm ib qho - peb ntawm nws qhov loj me.
2. Tshuab rau kev txhawb nqa kua hlau
ExOne nyob rau hauv Tebchaws Meskas tuaj nrog lub tshuab ua kua tin uas ua rau thaj tsam uas tau luam tawm nrog kua hlau. Tom qab luam ntawv, nws yog rhuab mus rau 232℃kom yaj lub tin thiab cia nws ntws tawm, uas yog hu ua "residue free tshem tawm." Txoj kev no tau siv los ua titanium alloy lub dav hlau qhov chaw, thiab nws tau ua kom yooj yim kaum zaug tshem tawm kev txhawb nqa.
3. Kev luam ntawv nrog kev pab ntawm ib qho chaw sib nqus
Lub tshuab hlau nplaum hlau tsim los ntawm MIT siv qhov chaw sib nqus sab nraud los tswj qhov uas tsis yog - cov hmoov hlau hlau sib nqus tau nthuav tawm, tsim cov qauv kev txhawb nqa ib ntus hauv thaj chaw uas raug ncua. Tom qab luam ntawv, siv qhov rov qab magnetic teb los pab cov hmoov tuaj yeem. Qhov no ua haujlwm zoo nrog cov ntaub ntawv uas teb rau cov hlau nplaum, suav nrog cobalt chromium alloys.
5, Teeb meem thiab kev coj ua zoo tshaj plaws hauv kev lag luam
1. Kev soj ntsuam ntawm ib qho xwm txheej
Hauv kev lag luam aerospace, GE Aviation tau txiav lub sijhawm nws siv los ua LEAP lub cav roj nozzles los ntawm 72 teev mus rau 8 teev los ntawm kev siv lub tshuab ua haujlwm. Qhov no tau nce txhua xyoo muaj peev xwm los ntawm 15 npaug.
Stryker siv cov txheej txheem tshem tawm electrochemical los kho cov khob acetabular, uas txo qis qhov seem ntawm kev txhawb nqa los ntawm 3% mus rau 0.05%. Qhov no ua tau raws li FDA cov qauv nruj rau cov hlau ion tso tawm.
2. Cov teeb meem loj
Tus nqi sib npaug: Cov nyiaj rov qab los ntawm kev nqis peev rau cov cuab yeej siv hluav taws xob tuaj yeem siv sijhawm txog 5 xyoos, thiab cov lag luam me thiab nruab nrab - cov lag luam me tseem ua haujlwm ntau ntawm tes.
Cov kev txwv ntawm cov khoom siv: Electrochemical thev naus laus zis tsuas yog siv tau nrog qee cov khoom sib xyaw ua ke, thiab nws yuav tsum tau hloov pauv ntau dua;
Kev tswj xyuas qhov tseeb: Txawm tias nws tsis tuaj yeem txhawb nqa cov txheej txheem sab hauv nyuaj xws li cov cua txias, tseem xav tau kev cuam tshuam lub cev.
