Kev pom zoo ntawm Kev Xaiv Ib Hlis Kev Caws Qib
Nyob hauv tus txheej txheem ntawm kev txiav txim siab ntawm kev sib cais rau ib qho kev thov, muaj ntau cov ntaub ntawv tseem ceeb uas tsim nyog los txhais kom meej qhov kev xav ua ntawm cais. Qee yam tseem ceeb dua lwm tus, tab sis txhua yam yuav tsum raug xav kom xaiv los tsim cov khoom tsim nyog.
Qee yam tseem ceeb uas yuav tsum tau muab xam yog:
Qhov hnyav, Qhov Coob, Lub Zej Zog Ntawm Cov Khoom Yuav Raug Rho Tawm - Qhov nyhav ntawm qhov chaw yuav muaj kev ncaj nraim rau hom thiab qhov loj ntawm qhov kev sib cais. Qhov loj me los yog cov duab ntawm cov cuab yeej tuaj yeem cuam tshuam kev cais tawm vim qhov no yuav qhia tau hais tias hom txuas thiab qhov chaw seem rau kev cais tawm. Qhov chaw tseem ceeb ntawm qhov chaw tseem ceeb kuj yog qhov tseem ceeb vim kev cais ntawm ntau hom kev them nyiaj yug yuav tsum muaj qhov sib txawv ntawm cov ntsiab lus ntawm cov cuab yeej vim muaj qhov nyhav. Cov chaw nyob ntawm cov neeg cais tawm ntawm lub plawv-ntawm lub ntiajteb txawj nqus - ntawm lub hauv paus ntawm cov khoom siv rau hauv lub dav hlau ntawm CG, piv txwv - yuav cuam tshuam cov qauv tsim ntawm cais.
Cov Kev Ntsib Teeb Meem Yuav tsum raug cais tawm - Qhov no yog qhov tseem ceeb rau qhov txhais ntawm qhov teeb meem yuav tsum tau hais los ntawm kev xaiv cais kev xaiv. Yuav kom xaiv qhov kev xaiv lossis kev tsim ntawm kev sib tw / kev sib cais, cov lus qhia no yuav tsum raug txhais raws li qhov zoo tau. Feem ntau, sinusoidal thiab / lossis random vibration spectra yuav muab txhais rau daim ntawv thov. Hauv ntau cov khoom ntawm cov khoom siv tub rog, cov kev sib tw ntawm kev sib tw ua tau dhau los ua ib qho chaw thiab thawj cov tub rog rau qhov kev xeem ntawm hom khoom no (xws li MIL-STD-810) tau hnyav ntau rau kev sib tw random, raws li qhov tseeb daim ntawv thov. Lwm cov khoom siv khoom, xws li hauv cov thawv xa khoom, yuav tsum tau muaj kev ntsuas ntau ntawm sinusoidal kev kuaj.
Feem ntau cov kev sib tw poob siab yuav tsum tau los ntawm ntau hom khoom siv. Cov kev ntsuam xyuas no txhais tau hais tias simulate cov ua hauj lwm zoo li no (piv txwv li, kev tsaws tsaws tsaws hauv av) lossis kev tuav (xws li, tshem tawm los yog poob) cov xwm txheej uas ua rau muaj kev cuam tshuam rau cov khoom siv.
Kev Nyuaj Tshaj Muaj Txij Nkawm Txij Nkawm Txij Nkawm - Txuas ntxiv rau qhov nyhav thiab kev xaav dynamic uas cov cais tawm yuav tsum ua li cas, nws muaj qee qhov xwm ceev uas yuav cuam tshuam rau kev xaiv ntawm cais. Ib qho piv txwv ntawm kev thauj khoom yog qhov thauj ntawm ib lub nkoj hauv kev siab ceev. Qhov dejnum no yuav tsum tau ua los ntawm kev sib cais thiab tuaj yeem ua tau, yog tias txaus txaus, yuav tsum ua kom muaj kev sib txawv ntawm kev sib cais. Cov loads yog feem ntau superposed rau dynamic loads.
Kev Tso Cai Pom Zoo - Qhov no yog lwm daim ntawv qhia. Yuav kom pom zoo cais tawm ib qho khoom siv, qhov lus teb ntawm qhov teeb meem yuav tsum paub. Cov chaw tsim khoom siv lossis tus neeg siv khoom siv yuav tsum muaj qee qhov kev paub ntawm lub pob txha ntawm chav tsev. Qhov no fragility, hais txog qhov kev cai tswj xyuas dynamic loadings yuav cia xaiv ntawm ib qho tsim nyog cais. Qhov no tej zaum yuav raug hais txog qhov sib npaug ntawm kev vam qaum dhau zaus los yog qhov siab tshaj plaws kev tsav tsheb uas cov khoom yuav ua rau tsis muaj kev ua yuam kev los yog tawg. Yog tias lub chaw tsim khoom siv lossis tus nruab khi uas muaj kev cuam tshuam nrog kev sib tw / kev poob siab, qhov kev tso cai no yuav muab teev tau tias qhov pom tau tias qhov ntuj tso thiab qhov siab tshaj plaws ntawm kev pom zoo pub thaum lub sijhawm xeem.
Cov lus cog tseg ntawm cov lus teb yuav tsum muaj nrog qhov kev tso cai siab tshaj plaws ntawm cov cuab yeej raug rho tawm. Qhov no yog qhov tseem ceeb rau kev xaiv tus neeg cais tawm vim nws yuav txhais tau qee cov kev tawm suab ntawm cov khoom siv limiting uas yuav tsum tau muab tso rau hauv qhov kev tsim tawm cais. Nws yog ib qho uas ua rau muaj kev tsis txaus siab ntawm qhov chaw "sway space" thiab cov lus taw kev uas tsim nyog rau kev cais tawm los ua qhov kev xav tau. Yuav kom cais tawm mus rau ib qho kev kawm tiav, nws yuav tsum tau tso cai kom meej meej tias cov lus tsa suab. Cov teeb meem hauv cheeb tsam no feem ntau tshwm sim thaum cov cais tawm tsis xav tau ntxov ntxov thaum tsim cov khoom los yog qhov chaw nyob ntawm cov cuab yeej.
