Kev Tshawb Fawb Txog Cov Khoom Siv thiab Engineering: Tsim thiab tsim khoom ntawm Inconel 939 turbine blades
Peb cov neeg siv khoom koom tes yog cov chaw tsim khoom ntawm pej xeem helicopters thiab cov dav hlau ua lag luam. Qhov kev thov rau lub cav qhov chaw yog siab heev, thiab nws yuav tsum tau durability. Raws li qhov yuav tsum tau muaj ntawm peb lub teb chaws, peb kuj hais txog qhov yuav tsum tau ua kom tau txais kev txuag hluav taws xob thiab kev txo qis emission.Ua kom tau raws li cov kev xav tau ntawm peb cov neeg siv khoom, tom qab kev sib tham los ntawm lub tuam tsev technical, peb txiav txim siab siv cov khoom siv inconel 939 rau kev tsim khoom, vim hais tias lub inconel 939 turbine hniav tuaj yeem tswj cov khoom zoo thiab muaj zog corrosion kuj ntawm qhov kub thiab txias, kom ntseeg tau tias kev siv tau zoo.
1.Design theem
Kev tsom xam cov neeg siv khoom xav tau: Peb pab pawg kws tshaj lij tau ua cov kev sib tham ntxaws ntxaws thiab txuas nrog cov neeg siv khoom hauv ntau yam, thiab nkag siab txog cov kev xav tau tshwj xeeb ntawm cov neeg siv khoom siv, suav nrog cov ntaub ntawv tseem ceeb xws li kev ntsuas kub thiab kev ua haujlwm siab, thiab lub neej expectancy.
Kev tsim qauv ua ntej: Raws li cov neeg siv khoom xav tau cov ntaub ntawv, peb pab pawg tau siv lub khoos phis tawj-pab tsim tsim (CAD) software los tsim cov qauv peb sab ntawm lub tshuab turbine, thiab siv cov cuab yeej siv tshuab ua kua dej (CFD) los xyuas qhov sib xws ntawm cov hniav. puab thiab optimize nws kom ntseeg tau qhov zoo tshaj plaws aerodynamic kev ua tau zoo.
Kev xaiv cov khoom siv: Tom qab txiav txim siab tus qauv tsim thiab kev lees paub nrog tus neeg siv khoom, Inconel 939 tau raug xaiv los ua peb cov khoom tseem ceeb los xyuas kom meej qhov zoo ntawm cov cua sov thiab lub zog ntawm cov khoom no.
2.Production txheej txheem
Tsim nyog rau precision casting: Vim qhov tshwj xeeb ntawm cov khoom siv inconel939 thiab cov yam ntxwv ua haujlwm nyuaj, peb xaiv cov cuab yeej siv tshuab los tsim cov turbine nyuaj no tom qab kev sib tham. Hauv kev tsim cov txheej txheem, peb yuav tsum tau tsim cov khoom siv ua yeeb yaj kiab siab thiab cov plhaub ceramic, nrog rau cov kua hlau txuas ntxiv thiab lwm cov kauj ruam.
Directional solidification: Txhawm rau kom ua tau raws li cov neeg siv khoom xav tau thiab txhim kho qhov sib xws ntawm cov kev coj noj coj ua ntawm cov khoom siv, peb siv cov txheej txheem kev taw qhia, uas tsis yog tsuas yog ua kom zoo dua qub ntawm lub koom haum sab hauv ntawm lub turbine hniav, txhim kho tag nrho cov khoom siv dag zog, thiab tseem tuaj yeem ua kom ntseeg tau tias cov neeg siv khoom zoo ib puag ncig thiab txuag hluav taws xob. Lub tswv yim ntawm kev txhim kho qhov zoo thiab kev ua haujlwm zoo.
Kev kho cua sov: Tom qab ua tiav cov txheej txheem casting, tag nrho peb cov khoom tiav tau dhau los ua cov txheej txheem kev kho cua sov, suav nrog kev kho kev daws teeb meem thiab kev laus hardening, uas ntxiv dag zog rau hardness thiab toughness ntawm cov khoom no.
3. Kev tshuaj xyuas thiab kev sim
Kev kuaj tsis muaj kev puas tsuaj: Peb xaiv los siv X-rays los kuaj xyuas sab hauv thiab sab nraud ntawm txhua yam khoom tiav rau qhov tsis xws luag lossis tawg uas tsis pom qhov muag liab qab.
Cov khoom siv tshuab kuaj cov khoom tiav: Vim muaj cov khoom tiav ntau, peb siv cov qauv tshuaj ntsuam xyuas los ua ib feem ntawm cov qauv rau kev kuaj tensile, kuaj qaug zog thiab lwm yam kev ntsuas kev ua tau zoo los xyuas kom meej tias cov khoom tuaj yeem ua tau raws li cov neeg siv khoom xav tau thiab zoo. cov qauv hauv txhua yam.
Kev simulation ib puag ncig: Peb tshem tawm cov khoom tiav peb tsim ua qauv, muab tso rau hauv qhov chaw simulated tiag tiag ua haujlwm, thiab simulate siv sijhawm ntev thiab kev ua haujlwm los xyuas qhov kev ruaj ntseg ntev thiab kev ntseeg siab ntawm cov khoom tiav.
4.Qhov tshwm sim qhia
Tom qab ob peb lub hlis ntawm kev tsim khoom thiab kev sib txuas lus rau cov neeg siv khoom, peb pab pawg kws tshaj lij thiab cov chaw tsim khoom tau ua tiav ib pawg ntawm cov khoom siv zoo inconel 939 turbine thiab ua tiav xa lawv mus rau cov neeg siv khoom. cov kev ntsuas tau tsim thaum xub thawj, tab sis kuj tau ntsib lawv lub tswv yim ntawm kev tiv thaiv ib puag ncig. Lawv dhau qhov kev cia siab hauv kev siv thiab ua tiav cov txiaj ntsig zoo.Cov neeg siv khoom tawm tswv yim kuj tau hais tias lawv tseem yuav koom tes nrog peb nyob rau ob peb xyoos tom ntej no, vam tias peb yuav txuas ntxiv ua cov khoom zoo, muab kev pabcuam rau lawv cov cav tshiab, thiab nqa. lawv cov nqi txuag tseem ceeb thiab cov txiaj ntsig ib puag ncig.
