Kev Txiav Txim Siab Hauv Kev Xaiv Lub Voos Rho Tawm
Hauv cov txheej txheem los txiav txim siab txog kev rho tawm kev tseev kom muaj lub suab cais rau ib daim ntawv thov tshwj xeeb, muaj ntau cov xov xwm tseem ceeb ntawm cov ntaub ntawv uas tsim nyog los txhais cov haujlwm xav tau ntawm cov cais tawm. Qee cov khoom tseem ceeb dua li lwm tus, tab sis txhua tus yuav tsum txiav txim siab txhawm rau txhawm rau xaiv lossis tsim cov khoom tsim nyog.
Qee qhov kev ua yuav tau txiav txim siab yog:
Qhov hnyav, Qhov Loj, Qhov Nruab Nrab-Ntawm Kev Siv Khoom Siv yuav tsum nyob twj ywm - Qhov nyhav ntawm chav yuav muaj cov kabmob ncaj qha rau ntawm hom thiab qhov loj ntawm cais tawm. Qhov loj lossis cov qauv ntawm cov khoom siv kuj tseem tuaj yeem cuam tshuam rau tus tsim kev tsim tawm txij li qhov no yuav tso cai hom kev txuas thiab qhov chaw muaj rau tus neeg rho tawm. Qhov chaw nruab nrab ntawm qhov chaw sib tsoo tseem tseem ceeb raws li cov neeg sib cais ntawm cov sib txawv thauj khoom sib txawv yuav tsim nyog ntawm cov ntsiab lus sib txawv ntawm cov khoom siv vim yog kev xa khoom hnyav. Cov chaw ntawm cov neeg nyob sib cais piv rau qhov nruab nrab-ntawm-kev sib tsoo - ntawm lub hauv paus ntawm cov cuab yeej piv rau hauv lub dav hlau ntawm CG, piv txwv - kuj tseem tuaj yeem cuam tshuam tus qauv tsim ntawm cais.
Hom Kev Ntsuam Xyuas Kom Tsis Txaus Ntshai Yuav Raug Cais - Qhov no yog qhov yooj yim rau cov ntsiab lus ntawm qhov teeb meem yuav tsum tau hais los ntawm tus txheej txheem xaiv neeg nyob ib puag ncig. Txhawm rau kom xaiv cov neeg kawm ntawv xaiv lossis tsim qauv kev tsim lub suab / poob siab, cov ntaub ntawv no yuav tsum tau txhais zoo li tsim nyog. Feem ntau, sinusoidal thiab / lossis kev co ntawm lub ntsej muag kev co lub ntsej muag yuav raug sau tseg rau daim ntawv thov. Hauv ntau qhov kev teeb tsa ntawm cov tub rog cov khoom siv hluav taws xob, kev ntsuam xyuas kev co tshee tau dhau los ua qhov tsis sib xws thiab thawj qhov kev ua tub rog tshwj xeeb rau kev sim cov khoom siv no (xws li MIL-STD-810) tau tso rau qhov kev qhia hnyav rau kev co, ua kom haum rau cov ntawv thov tiag tiag. Lwm cov khoom siv sib ntxiv, xws li hauv cov thawv xa khoom, yuav xav tau cov nqi ntawm qhov ntshav siab ntawm sinusoidal kev kuaj ntsuas.
Kev ntsuam xyuas Poob siab feem ntau xav tau los ntawm ntau yam khoom siv. Cov kev sim no txhais tau tias simulate cov kev ua haujlwm (piv txwv, cov tsaws tsaws ntawm dav hlau) lossis tuav (piv txwv li, lub rooj ntev zaum lossis poob) uas ua rau muaj kev cuam tshuam kev thauj khoom ntawm cov khoom siv.
Static Loadings Lwm qhov uas tsis yog qhov hnyav txhawb nqa - Ntxiv rau qhov hnyav thiab cov khoom siv thauj khoom uas cov neeg sib cais yuav tsum xav, muaj qee cov khoom zoo li qub uas tuaj yeem cuam tshuam qhov xaiv ntawm cov cais tawm. Ib qho piv txwv ntawm cov kev thauj khoom no yog lub luag haujlwm uas tsim los ntawm ib lub dav hlau nyob hauv qhov chaw siab nrawm. Qhov no maneuver chaw thau khoom yuav tsum tau ua haujlwm los ntawm kev cais tawm thiab tuaj yeem, yog tias hnyav txaus, xav tau ib qho nce ntxiv hauv qhov loj me ntxiv. Cov kev ntim no yog feem ntau superposed ntawm lub zog load.
Cia Lub Txheej Txheem Teb Tsim - Qhov no yog lwm cov ntsiab lus yooj yim. Txhawm rau kom tsim nyog cais cais ib qho ntawm cov cuab yeej siv, sab lus teb ntawm qhov teeb meem yuav tsum paub. Cov cuab yeej tsim tawm lossis tus neeg siv khoom yuav tsum muaj qee qhov kev paub txog kev puas tsuaj ntawm chav ntsuas. Qhov tsis txaus ntseeg no, cuam tshuam nrog lub teev tshwj xeeb loadings yuav cia xaiv tus tsim nyog cais tawm. Qhov no yuav qhia tau raws li qhov kev co qib piv rau lub zaus lossis lub siab thauj khoom siab tshaj plaws uas cov khoom siv tuaj yeem thev dhau yam tsis ua haujlwm lossis tawg. Yog tias cov cuab yeej tsim khoom siv los yog lub chaw tsim khoom muaj kev paub txog kev co / poob siab, qhov kev tso cai no yuav tau muab sau cia raws li qhov tso cai ib txwm muaj thiab qhov siab tshaj plaws uas tau tso cai thaum lub sijhawm kuaj.
Cov kev qhia tshwj xeeb ntawm cov lus pom zoo tso cai ntawm cov lus teb yuav tsum suav nrog qhov ua tau zoo siab tshaj plaws ntawm cov cuab yeej sib cais. Qhov no yog ib qho tseem ceeb rau kev xaiv ntawm tus cais tawm vim tias nws yuav txhais qee qhov kev hloov suab sib txawv uas yuav tsum tau siv rau hauv tus qauv tsim tawm. Nws yog qhov ncaj ncees kom muaj qhov tsis sib xws ntawm qhov tso cai "chaw txav mus los" thiab cov lus tsa suab tsim nyog rau tus neeg cais tawm los ua qhov haujlwm xav tau. Txhawm rau cais tawm mus rau qee qhov kev kawm, nws yog qhov yuav tsum muaj qhov tseeb ntawm kev txav chaw. Cov teeb meem hauv cheeb tsam no feem ntau tshwm sim thaum kev sib cais tsis tau txiav txim siab thaum ntxov hauv kev txheej txheem ntawm kev tsim cov khoom siv lossis cov txheej txheem qhov chaw ntawm cov cuab yeej.
