MTBF yog ib qho kev ntsuas rau qhov ua tsis tiav hauv cov txheej txheem kho tauRau kev ua tsis tiav uas yuav tsum tau hloov pauv, feem ntau tib neeg siv lo lus MTTF (lub sijhawm ua tsis tiav). Piv txwv li, xav txog lub cav tsheb. Thaum xam lub sij hawm nruab nrab ntawm unscheduled engine tu, koj yuav siv MTBF-lub sij hawm nruab nrab ntawm tsis ua hauj lwm.
MTBF siv rau dab tsi?
Lub sijhawm nruab nrab ntawm kev ua tsis tiav (MTBF) yog lub sijhawm nruab nrab ntawm qhov kev puas tsuajMTBF yog ib qho tseem ceeb ntawm kev ntsuas ntsuas ntsuas kev ua tau zoo, kev nyab xeeb, thiab cov khoom tsim, tshwj xeeb tshaj yog rau qhov tseem ceeb lossis txoj haujlwm nyuaj. cov khoom muaj nqis, xws li cov tshuab hluav taws xob lossis cov dav hlau. Nws kuj yog siv los txiav txim qhov kev ntseeg tau ntawm ib qho cuab tam.
MTBF ntawm 1000 teev qhia peb li cas?
MTBF= Ntau lub sijhawm ua haujlwm ÷ Tus naj npawb ntawm kev ua tsis tiav Lub twj tso kua mis ua haujlwm rau 100 teev txhua lub sijhawm ntawm ib xyoos, tag nrho 1,000. Cov twj tso kua mis ua tsis tau 16 zaug hauv tag nrho xyoo ntawd. Qhov no txhais tau hais tias lub sijhawm nruab nrab ntawm kev ua tsis tiav rau cov twj no yog 62.5 teev.
MTBF yog dab tsi yog tias tsis ua haujlwm?
MTBF. Peb suav MTBF los ntawm kev faib tag nrho lub sijhawm ua haujlwm los ntawm tus lej ntawm kev ua tsis tiav thaum lub sijhawm teev tseg. Yog li ntawd, nws yog inverse ntawm qhov tsis ua hauj lwm tus nqi. MTBF=lub sijhawm ua haujlwm / tsis muaj. ntawm kev ua tsis tiav.
MTBF puas yog qhov ntsuas kev ntseeg tau zoo?
MTBF yog ib qho kev ntsuas ntawm qhov kev ntseeg siab; qhov siab dua MTBF, qhov siab dua qhov kev ntseeg siab ntawm cov khoom. Qhov kev sib raug zoo no tau piav qhia hauv kab zauv: Kev ntseeg siab=e-(lub sijhawm / MTBF). Muaj ob peb qhov kev hloov pauv ntawm MTBF koj tuaj yeem ntsib.
