Los ntawm Hluav Taws mus rau Dav Hlau: Uncovering qhov kev xav ntawm thermal thev naus laus zis hauv kev tsim cov tshuab aeroengines
inhibition txheej txheem
Cov khoom zoo heev ntawm ib leeg siv lead ua superalloy feem ntau yog vim kev tshem tawm ntawm cov ciam teb ntawm ib leeg siv lead ua, thiab recrystallization yuav txo tau qhov kub thiab txias tsis kam ntawm tus thawj tib siv lead ua alloy. Tom qab ib leeg siv lead ua hniav casting, nws yog ib qho tsim nyog yuav tsum tau ua cov roj zaj duab xis qhov kev ua, tenon hniav sib tsoo, ntug phaj sab milling, hniav tip casting txheej txheem qhov vuam, kev kho cua sov, sib dhos thiab lwm yam kev ua haujlwm tom qab. Nyob rau hauv cov txheej txheem ntawm lub cav ua haujlwm, cov hniav yog raug rau cov cua kub thiab txias cuam tshuam thiab kub kub, loj load thiab nruj kev co thaum lub sij hawm high-ceev kev sib hloov, thiab recrystallization yog ua tau. Muaj ob peb lub turbine hniav tsis ua haujlwm. Yog li ntawd, nyob rau hauv xyoo tas los no, kev tshawb fawb hauv tsev thiab txawv teb chaws tau txais kev kho cua sov ua ntej, carburizing, txheej thiab tshem tawm cov deformation txheej thiab lwm yam kev cuam tshuam rau inhibit recrystallization thiab ntxiv ciam teb ntxiv dag zog rau cov recrystallization kho ua hauj lwm.
3D tshuab luam ntawv
3D luam ntawv, tseem hu ua additive manufacturing, integrates CAD, CAM, hmoov metallurgy, laser ua thiab lwm yam technologies. Siv 3D luam ntawv thev naus laus zis, peb tuaj yeem tig qhov kev xav ntawm "lub hlwb" mus rau hauv peb qhov chaw, thiab luam cov duab ntawm ib feem ntawm lub computer mus rau hauv "tiag tiag". 3D luam ntawv thev naus laus zis tau ua "kev hloov pauv" hloov pauv hauv kev tsim tshuab thiab ua cov tswv yim. Monash University hauv Australia tau ua tiav lub ntiaj teb thawj 3D tshuab luam ntawv dav hlau. Nyob rau tib lub sijhawm, nws tseem ua haujlwm nrog Boeing, Airbus Group thiab Safran Group los muab 3D luam ntawv cav qauv rau Boeing thiab lwm tus rau kev sim davhlau. Nrog 3D tshuab luam ntawv, lub sijhawm tsim khoom ntawm lub cav qhov chaw tuaj yeem raug txo los ntawm peb lub hlis mus rau rau hnub.
Hauv Suav teb, 3D luam ntawv thev naus laus zis tau siv los kho thiab rov qab siv cov hniav ntaj coj qhov chaw ntawm turbofan cav high-pressure compressor rotor hniav. 3D tshuab luam ntawv tau siv los tsim cov khoom tsis muaj kabmob thiab qhov chaw zoo li qub ntawm lub cav, tab sis cov khoom siv ntawm cov khoom tau raug tshuaj xyuas, tib lub sijhawm, kev siv 3D tshuab luam ntawv los tsim cov cav rotor, cov kabmob , thiab lwm yam, kuj tau ua cov kev tshawb fawb dav dav.
Hniav sab ntug (pem hauv ntej thiab nram qab ntug) ua tshuab
Lub machining zoo ntawm inlet thiab tso tawm ntug ntawm aero engine hniav yog ib qho ntawm cov yam tseem ceeb cuam tshuam rau aerodynamic kev ua tau zoo ntawm aero engine. Lub inlet thiab tso tawm ntug kuj yog qhov tsis xws luag ntawm cov hniav thiab qhov tsis xws luag rhiab cheeb tsam ntawm titanium alloy. Feem ntau ntawm lub cav tsis ua haujlwm yog tshwm sim los ntawm kev ua haujlwm tsis zoo ntawm lub qhov nkag thiab tso tawm ntawm cov hniav. Vim tias qhov nkag thiab tso tawm ntawm cov hniav yog qhov thinnest ntawm cov hniav thiab ntug ntawm cov hniav, nws cov rigidity tsis zoo thiab cov txheej txheem deformation loj, thiab qhov nkag thiab tawm ntug ntawm cov hniav ua tiav feem ntau tshwm square thiab taw tes. Nyob rau hauv lub loj zus tau tej cov cav tov, cov teeb meem thev naus laus zis tseem ceeb ntawm kev ua haujlwm siab thiab kev ua haujlwm zoo ntawm cov hniav thiab cov pa tawm ntawm ntug kev ua tsis tau tiav.
Adaptive processing technology
Adaptive machining thev naus laus zis tau muab faib ua peb hom, uas yog, kev hloov kho kev npaj ntawm cov cuab yeej txoj haujlwm trajectory, kev hloov pauv ntawm kev tswj cov lej thiab kev hloov kho machining ua ke nrog kev tshawb pom digital [3]. Nyob rau hauv Suav teb, adaptive machining technology tau ua tiav nyob rau hauv precision forging / dov hniav machining, puas hniav kho thiab linear sib txhuam vuam monolithic hniav disc machining. Txawm hais tias adaptive machining thev naus laus zis tau ua tiav thiab kev txhim kho hauv txoj kev xav thiab kev coj ua, kev siv engineering ntawm kev siv tshuab ua haujlwm hloov pauv tseem yog cov cuab yeej tshawb fawb kub hauv aero engine manufacturing.
Anti- qaug zog manufacturing technology
Cov khoom siv qaug zog thiab qhov chaw machining defects tau dhau los ua qhov tseem ceeb ntawm aero engine qhov chaw tsis ua haujlwm, thiab qhov tsis ua haujlwm tau dhau los ua ib qho kev loj hlob, yog li "kev tsim khoom los tiv thaiv kev qaug zog" tau dhau los ua cov cuab yeej kub hauv aero engine manufacturing. Anti-fatigue manufacturing technology hais txog cov txheej txheem tsim khoom uas txhim kho lub neej qaug zog ntawm qhov chaw los ntawm kev hloov lub koom haum thiab kev ntxhov siab ntawm cov khoom siv hauv cov txheej txheem tsim khoom yam tsis hloov cov khoom siv thiab ntu loj. Lub neej qaug zog feem ntau cuam tshuam los ntawm kev kho cua sov, ib puag ncig corrosion, nto zoo, kev nyuaj siab concentration, kev nyuaj siab nto thiab lwm yam. Txoj hauv kev tseem ceeb ntawm kev tsim khoom los tiv thaiv kev qaug zog yog txo qis kev ntxhov siab thiab txhim kho lub zog ntawm qhov chaw. Txo kev ntxhov siab concentration yog los xyuas kom meej qhov kev ncaj ncees ntawm machined nto, thiab txoj kev zoo tshaj plaws los txhim kho lub zog saum npoo ntawm qhov chaw yog tua peening. Nyob rau hauv tus txheej txheem ntawm aircraft cav los tiv thaiv qaug zog manufacturing, ntau yam tshiab txhaj tshuaj peening xov xwm tau tsim nyob rau hauv cov tsoos txhaj tshuaj peening txheej txheem, thiab cov tshiab technologies ntawm laser txhaj tshuaj peening, ultrasonic txhaj tshuaj peening thiab kub siab dej txhaj peening tau lug siv. .
Noog ntaus tiv thaiv technology
Kev tshwm sim tsis tu ncua ntawm cov noog tawm tsam tau dhau los ua qhov teeb meem uas tsis tuaj yeem zam hauv kev txhim kho cov tshuab aero, thiab kev tshawb fawb dav tau ua nyob hauv tsev thiab txawv teb chaws. Thaum Lub Xya Hli 2015, Tebchaws Meskas FAA tau tshaj tawm tsab ntawv ceeb toom "Bird strike Requirements for transport aircraft", uas tsis tsuas yog muab cov kev cai tshwj xeeb thiab cov kev cai rau yav tom ntej kev tiv thaiv noog thiab cov khoom txawv teb chaws kev raug mob ntawm cov tshuab dav hlau, tab sis kuj tau taw qhia lwm qhov tshiab. kev tshawb fawb kev taw qhia rau kev txhim kho cov khoom siv cav tshiab thiab cov qauv tsim qauv tshiab.
