Koj paub ntau npaum li cas txog kev tsim kho tshuab?
Kev tsim kho tshuab yog ib ceg ntawm engineering uas siv ntau lub hauv paus ntsiab lus thiab cov tswv yim los tsim, txheeb xyuas thiab ua kom zoo dua cov tshuab thiab cov khoom siv.Kev tsim kho tshuab suav nrog kev nkag siab txog lub hom phiaj ntawm cov khoom siv lossis cov txheej txheem, xaiv cov khoom tsim nyog, suav nrog ntau yam, xws li kev ntxhov siab thiab cov kab mob thiab kev quab yuam, thiab ua kom ntseeg tau thiab ua haujlwm tau zoo.
Mechanical tsim muaj xws li tshuab tsim, qauv tsim, tsim mechanism thiab tsim khoom.Cov khoom tsim muaj kev txhawj xeeb nrog kev tsim cov khoom siv lub cev xws li cov khoom siv, cov khoom siv thiab lwm yam khoom siv.Lub tshuab tsim, ntawm qhov tod tes, tsom rau kev tsim cov tshuab xws li cav, turbines thiab cov cuab yeej tsim khoom.Mechanism tsim muaj kev txhawj xeeb nrog kev tsim cov txheej txheem uas hloov cov khoom nkag mus rau qhov xav tau.Kev tsim qauv yog cov kauj ruam kawg.Nws suav nrog kev tsom xam thiab tsim cov qauv xws li txuas hniav, cov tsev, thiab cov thav ntawv rau lawv lub zog, ruaj khov, kev nyab xeeb, thiab kav ntev.
Cov txheej txheem tsim tshwj xeeb zoo li cas?
Cov txheej txheem tsim qauv feem ntau suav nrog ntau cov kauj ruam, xws li kev txheeb xyuas qhov teeb meem kev tshawb fawb thiab kev tsom xam, kev tsim lub tswv yim thiab cov ncauj lus kom ntxaws tsim thiab prototyping, nrog rau kev sim thiab kev nthuav dav.Nyob rau hauv cov theem no engineers siv ntau cov tswv yim thiab cov cuab yeej xws li computer-aided design (CAD) software, finite element analysis (FEA) thiab simulation los xyuas thiab txhim kho tus tsim.
Yam dab tsi uas cov neeg tsim qauv yuav tsum xav txog?
Kev tsim kho tshuab feem ntau suav nrog cov khoom xws li kev tsim khoom, ergonomics, kev ua haujlwm tau zoo thiab kev ruaj ntseg.Cov kws tsim qauv sim tsim cov qauv uas tsis yog tsuas yog siv tau thiab ua tau zoo txawm li cas los xij, lawv kuj yuav tsum xav txog cov neeg siv khoom xav tau, kev cuam tshuam ib puag ncig thiab kev txwv nyiaj txiag.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaj chaw ntawm kev tsim kho tshuab ib qho kev nthuav dav thiab txuas ntxiv mus nrog cov ntaub ntawv tshiab, thev naus laus zis thiab cov txheej txheem tsim los tas li.Yog li, cov neeg tsim khoom siv tshuab yuav tsum txuas ntxiv kho lawv cov kev txawj ntse thiab kev paub kom nyob twj ywm hauv qhov ua ntej ntawm kev txhim kho thev naus laus zis.
Cov hauv qab no yog cov ntsiab lus kev paub txog kev tsim kho tshuab sau thiab teeb tsa los ntawm Anebon pab pawg engineering los qhia rau cov npoj yaig.
1. Qhov ua rau tsis ua hauj lwm hauv cov khoom siv tshuab yog: kev puas tsuaj dav dav lossis ntau dhau qhov seem deformation nto puas tsuaj rauprecision tig Cheebtsam(corrosion hnav, txhuam kev qaug zog thiab hnav) Ua tsis tiav vim muaj kev cuam tshuam ntawm kev ua haujlwm ib txwm muaj.
2. Cov khoom tsim tsim yuav tsum muaj peev xwm ua tau raws li: cov kev cai kom tsis txhob ua tsis tau raws li lub sijhawm teev tseg (lub zog lossis kev nruj, lub sijhawm) thiab cov kev xav tau ntawm cov txheej txheem, kev lag luam, cov kev xav tau zoo, thiab cov kev xav tau rau kev ntseeg tau.
