Yuav ua li cas los ntsuas qhov txias txias ntawm hlau 3D luam ntawv pwm?

Ib, Lub ntsiab tseem ceeb ntawm kev ntsuas kev ua haujlwm txias
1. Kev ntsuas qhov ntsuas kub ua haujlwm
Kev ntsuas thermal conductivity yog ib txoj hauv kev tseem ceeb kom paub tias cov khoom thauj tau zoo npaum li cas. ASTM E1461 laser flash txoj kev tuaj yeem ntsuas qhov thermal diffusivity ntawm pwm cov ntaub ntawv ntawm -100 thiab 500 degrees Celsius. Ib pab neeg tshawb fawb tau sim 3D luam tawm H13 pwm hlau thiab pom tias nws cov thermal conductivity yog 28.5W / (m · K), uas yog 12% ntau dua li cov txheej txheem forging. Qhov no yog vim 3D luam ntawv tsim ib tug tshwj xeeb zoo grain qauv.

Lub hom phiaj tseem ceeb ntawm kev tsom xam thermal kuj yog kom paub seb cov pwm hloov pauv tau zoo npaum li cas. Ua kom kub gradient huab maps, koj tuaj yeem muab cov thermocouples ntawm cov ntsiab lus tseem ceeb ntawm cov pwm thiab siv cov thev naus laus zis thev naus laus zis los ua ke. Ib qho kev sim ua los ntawm ib lub tuam txhab uas ua rau lub tsheb qhov chaw qhia tau hais tias qhov kub ntawm lawv cov 3D luam ntawv aluminium alloy tuag-casting pwm core nyob rau hauv ± 3℃tom qab ua 1000 pwm ua ke. Qhov no yog 60% qis dua li cov pwm qub.

2. Kev ntsuam xyuas cov dej dynamics
Kev ntsuam xyuas tus cwj pwm poob siab yog ib txoj hauv kev zoo kom pom tias qhov tsim ntawm cov dej txias hauv Circuit Court yog qhov tsim nyog. Micronics PT100 flow calibration device tuaj yeem txheeb xyuas qhov poob siab hauv txoj kev dej thaum tus nqi ntws ntawm 0.1 txog 100L / min. Cov ntaub ntawv kawm ntawm lub tshuab ntim khoom siv hluav taws xob tau pom tias 3D- luam tawm kauv dej txias channel poob tsuas yog 0.8kPa ntawm tus nqi ntws ntawm 20L / min, uas yog 45% tsawg dua li cov tsoos drilling dej channel. Qhov no qhia tau hais tias nws cov channel tsim muaj ntau dua nyob rau hauv txoj kab nrog cov ntsiab lus dej dynamics.

Ib tug multi-channel flow sensor network yog siv los ua qhov kev ntsuam xyuas ntws sib xws. Ib pab neeg tshawb fawb tau teeb tsa 12 qhov chaw saib xyuas hauv qhov nyuaj 3D- luam tawm kab noj hniav pwm. Lawv tau pom tias qhov sib txawv ntawm txhua qhov channel tau khaws cia nyob rau hauv ± 2% kom paub tseeb tias qhov nruab nrab cua txias tau kis tusyees. Cov txheej txheem kuaj no yog qhov zoo heev rau siab -cov pwm precision siv hauv kev lag luam aerospace. Piv txwv li, ib qho kev txhawb nqa satellite pwm uas ua kom zoo dua cov qauv dej kom txo tau cov khoom lag luam warpage deformation ntawm 0.3mm txog 0.05mm.

2, Ib qho system rau kev sim ntawm cov nplai sib txawv
1. Kev ntsuas ntawm qhov ntsuas qhov ntsuas me me
Kev tshawb nrhiav metallographic tuaj yeem qhia tau ib qho - ntawm -ib - zoo microstructural zog ntawm 3D luam ntawv. Nrog rau Olympus BX53M metallographic microscope, koj tuaj yeem pom cov nplej zoo uas tau ua los ntawm cov txheej txheem laser hmoov txaj melting (LPBF). Cov nplej no muaj ntau dua 50% me dua li cov uas ua nrog cov txheej txheem casting. Qhov microstructure no ua rau cov khoom zoo dua ntawm kev cuam tshuam nrog thermal qaug zog. Tom qab 10 ^ 6 lub voj voog thermal, ib qho kev sim ua kom pom tias 3D luam tawm pwm tseem muaj cov kab lis kev cai ua tiav, thaum cov pwm tsoos muaj qhov sib txawv.

Micromeritics AutoPore V mercury intrusion porosimeter yog siv los nrhiav cov porosity. Nws tuaj yeem pom qhov twg cov pores nyob hauv pwm. Kev kuaj pwm kev kho mob pom tau hais tias los ntawm kev hloov cov chaw luam ntawv, qhov porosity tuaj yeem txo qis los ntawm 0.5% mus rau 0.08%, thiab qhov pore loj yog feem ntau ntawm 1 thiab 5 μm. Cov qauv tuab no txwv tsis pub cov cua txias nruab nrab los ntawm kev xau thiab ua rau cov pwm muaj zog.

2. Kev sim ntawm qhov loj
Thermal imaging dynamic monitoring yog ib txoj hauv kev yooj yim kom pom tias cov pwm txias npaum li cas. Lub koob yees duab FLIR T865 thermal imaging lub koob yees duab tuaj yeem qhia koj seb qhov kub ntawm pwm qhov chaw txawv li cas hauv lub sijhawm. Nws muaj kev daws teeb meem ntawm 640 × 480 thiab tuaj yeem pom qhov kub ntawm -40℃txog 1500 degree. Thaum kuaj ib lub tsheb cav lub tog raj kheej lub taub hau pwm, cov kws tshawb fawb piv cov duab thermal imaging ntawm 3D luam ntawv thiab cov pwm tsoos. Lawv pom tias qhov ntsuas kub ntawm cov qauv sib txawv ntawm 3D luam ntawv pwm tsuas yog 1.2 degree, uas yog 75% qis dua li cov pwm ib txwm muaj. Qhov no qhia tau hais tias cov dej txias conformal Circuit Court tsim ua qhov sib txawv loj hauv thermal tshuav nyiaj li cas.

MTS 370.10 qaug zog kuaj tshuab yog siv rau kev sim lub neej qaug zog. Nws simulates yuav ua li cas pwm qhov kev ua tau zoo yuav hloov tom qab 1 lab kub thiab txias cycles nrog ib tug load ntawm ± 25kN . 3D luam pwm steel khaws 90% ntawm nws thawj hardness tom qab 500,000 cycles, thaum tsoos pwm poob 30% ntawm lawv hardness nyob rau hauv tib yam kev mob. Qhov no yog vim 3D luam ntawv thev naus laus zis tau tshem tawm ntawm kev ntxhov siab sab hauv.

3, Kev siv cov txheej txheem xeem dhau los
1. Kev siv tshuab ntawm cov ntxaib digital
Ib tus qauv ntxaib digital ntawm cov txheej txheem pwm txias tuaj yeem ua los ntawm kev sib txuas Moldflow pwm flow tsom software nrog kev kawm tshuab. Ib pab pawg kawm tau tsim cov qauv AI uas tuaj yeem kwv yees qhov kub, ceev, thiab kev sib faib siab nyob rau hauv ib cheeb tsam los ntawm kev cob qhia ntawm 36,000 cov ntaub ntawv ntawm cov ntaub ntawv parameterized fin. Tus qauv cov txiaj ntsig tau zoo sib xws nrog cov ntaub ntawv xeem tiag tiag, nrog rau 95% qhov tseeb. Qhov no yog 40% zoo dua li cov txheej txheem empirical thiab txo lub sijhawm nws siv los ua pwm.

2. Ib lub network ntawm me me sensors
Tso lub micro kub thiab siab sensor array nyob rau hauv lub pwm yuav cia koj saib xyuas cov txheej txheem txias nyob rau hauv lub sij hawm. Ib txoj kev tshawb fawb tshwj xeeb tau siv 24 MEMS sensors hauv 3D- luam tawm cov khoom siv hluav taws xob me me los ntsuas qhov ntsuas kub hauv cheeb tsam ntawm 0.1 degree, muab cov ntaub ntawv meej txhawb rau kev tswj kav dej. Cov txheej txheem no yog qhov zoo rau kev ua siab -cov pwm precision hauv kev lag luam aerospace. Piv txwv li, lub foob pob hluav taws lub cav nozzle pwm uas tswj qhov kub thiab txias ntawm qhov kub ntxhov siab nyob rau hauv ± 5℃los ntawm lub sensor network.

4. Cov qauv thiab cov qauv rau kev sim hauv kev lag luam
TS EN ISO 23499-2017 "Kev Ntsuam Xyuas Cov Qauv Zoo rau Hlau 3D Luam Ntawv," tau luam tawm los ntawm International Organization for Standardization (ISO). Nws teev tus qauv rau kev ntsuas kev ua haujlwm txias. Kev ntsuam xyuas thermal conductivity yuav tsum ua raws li tus qauv ASTM E1461, kev ntsuas kev poob siab yuav tsum ua raws li ISO 527-2 specification, thiab lub neej qaug zog yuav tsum ua raws li ISO 1217 tus qauv. Hauv Suav teb, cov qauv zoo li GB / T 39251-2020 "Txoj Kev Ua Cuam Tshuam rau Cov Khoom Siv Hluav Taws Xob hauv Cov Khoom Siv Ntxiv" muab kev lag luam tag nrho cov txheej txheem kev qhia tshwj xeeb.
