Qhov sib txawv tseem ceeb ntawm PFMEA thiab DFMEA yog tias PFMEA pab txhawm rau txheeb xyuas qhov ua tsis tau zoo ntawm cov txheej txheem kev lag luam tshwj xeeb thaum DFMEA pab txhawm rau txheeb xyuas qhov ua tsis tiav ntawm tus qauv tsim khoom.
Tus txheej txheem ntawm FMEA (Failure Mode Effects Analysis) pab txheeb xyuas cov peev txheej tsis ua haujlwm ntawm cov txheej txheem ntawm kev tswj xyuas kev ua haujlwm thiab kev tsim qauv ntawm cov khoom tsim kho theem nyob rau hauv ib qho system thiab faib cov kev ua tsis tiav raws li qhov yuav tshwm sim thiab qhov hnyav ntawm qhov ua tsis tiav. Hom kev ua tsis tiav yog hais txog tej yam tsis xws luag lossis ua yuam kev hauv kev tsim, txheej txheem, lossis ib yam khoom, uas cuam tshuam rau tus neeg siv khoom. "Kev tsom xam qhov cuam tshuam" yog hais txog kev kawm txog qhov tshwm sim ntawm qhov ua tsis tiav.
PFMEA yog dab tsi?
PFMEA sawv cev rau Cov Txheej Txheem Tsis Ua Haujlwm Hom Kev Tshawb Fawb. Cov txheej txheem no tuaj yeem txheeb xyuas cov kev ua tsis tiav hauv cov txheej txheem ntawm qib ua haujlwm. Feem ntau, ib pab neeg muaj kev paub dhau los ua PFMEA. Cov txheej txheem yooj yim yog sau cov ntaub ntawv txaus rau qhov ua rau tsis ua haujlwm hom los kho lossis txo qhov cuam tshuam ntawm hom tsis ua haujlwm.
Tsis tas li ntawd, PFMEA yog cov cuab yeej tsim qauv siv los ntawm txhua lub koom haum. Nws pab hauv kev tsim cov kev cuam tshuam ntawm cov qauv kev ua tsis tiav thiab saib xyuas qhov tseem ceeb ntawm cov haujlwm tsim nyog los daws qhov kev pheej hmoo. PFMEA tau sau tseg thiab nthuav tawm ua ntej tshaj tawm cov txheej txheem tshiab los txo cov kev phom sij. Ntxiv mus, nws tseem tuaj yeem siv qhov no rau cov txheej txheem prevailing thiaj li ua tiav kev txhim kho txuas ntxiv ntawm qhov system.
DFMEA yog dab tsi?
DFMEA sawv cev rau Kev Tsim Kho Tsis Ua Haujlwm Kev Tshawb Fawb. Cov txheej txheem no pab txhawm rau txheeb xyuas qhov ua tsis tiav hauv cov khoom tsim khoom ntawm theem kev txhim kho. Feem ntau ntawm cov xwm txheej, engineers siv qhov no ua tus txheej txheem los tshawb nrhiav qhov ua tau ntawm kev tsim tsis ua haujlwm hauv qhov xwm txheej tiag tiag lossis siv.
Tus thawj cuab yeej engineers rau DFMEA yog DFMEA matrix. Cov matrix no nthuav tawm cov qauv rau kev sau thiab sau cov ntaub ntawv ntsig txog nrog rau cov kev qhia tshwj xeeb, hnub teeb meem, hnub hloov kho, thiab cov tswv cuab hauv pab pawg. Feem ntau, DFMEA yog pab pawg ua haujlwm ntawm cov kws tshaj lij thiab tej zaum yog pab pawg sib koom ua haujlwm. Ntxiv mus, DFMEA tsis cia siab rau cov txheej txheem tswj kom kov yeej kev tsim tsis tau
Qhov Zoo sib xws ntawm PFMEA thiab DFMEA yog dab tsi?
- PFMEA thiab DFMEA yog ob hom kev cuam tshuam tsis ua haujlwm.
- Cov kauj ruam hauv DFMEA thiab PFMEA zoo ib yam, tab sis lawv muaj ob daim ntawv thov sib txawv.
- Ob DFMEA thiab PFMEA qhia txog qhov ua tsis tiav, qhov hnyav ntawm qhov txaus ntshai, kev tswj hwm uas twb muaj lawm, cov lus pom zoo thiab kev txhim kho tom qab tau pom zoo ua.
- Lub hom phiaj ntawm ob qho tib si yog kom txo lossis tsis txhob muaj kev cuam tshuam loj ntawm cov khoom thiab kev tsim khoom.
- Cov txheej txheem no tuaj yeem txo tus nqi ntawm kev tsim lossis kev ua haujlwm ib yam nkaus.
- Tsis tas li ntawd, qee qhov kev ua tsis tiav yuav tsis raug txo qis ntawm DFMEA. Cov kev ua tsis tiav no tuaj yeem xa mus rau PFMEA rau kev tswj hwm qhov tsim nyog rau kev txhim kho cov khoom lag luam.
Qhov txawv ntawm PFMEA thiab DFMEA yog dab tsi?
Qhov sib txawv tseem ceeb ntawm PFMEA thiab DFMEA yog tias PFMEA koom nrog cov txheej txheem thaum DFMEA suav nrog cov khoom tsim. Lub hom phiaj tseem ceeb ntawm DFMEA yog txhawm rau nthuav tawm qhov ua tsis tiav ntawm cov khoom tsim qauv thaum lub hom phiaj tseem ceeb ntawm PFMEA yog txhawm rau nthuav tawm cov txheej txheem ua tsis tiav. Kev tshuaj xyuas yooj yim ntawm DFMEA yog ua los ntawm kev siv cov khoom schematic, thaum PFMEA yog ua los ntawm cov txheej txheem khiav dej num. Lwm qhov sib txawv ntawm PFMEA thiab DFMEA yog tias PFMEA tshwm sim ntawm theem ua haujlwm thaum DFMEA tshwm sim ntawm theem kev txhim kho.
Summary- PFMEA vs DFMEA
Qhov sib txawv tseem ceeb ntawm PFMEA thiab DFMEA yog tias PFMEA pab txhawm rau txheeb xyuas qhov ua tsis tiav ntawm cov txheej txheem tshwj xeeb ntawm qib kev ua haujlwm thaum DFMEA pab txheeb xyuas qhov ua tsis tiav ntawm cov khoom tsim ntawm kev tsim thiab kev loj hlob. Ntxiv mus, cov txheej txheem no yuav txo qis cov nqi tsim khoom thiab nrog rau kev ua tsis tiav hauv cov khoom xa tawm.
