Cov kev taw qhia tawm yog ib qho tseem ceeb ntawm ntau yam khoom siv tshuab siv tshuab, muab kev txav mus los ntawm txoj kab ncaj nraim.Txhawm rau kom ntseeg tau tias qhov kev ua tau zoo tshaj plaws ntawm cov ntawv qhia linear, nws yog ib qho tsim nyog yuav tsum tau ua kom raug xam nws cov peev txheej nqa, tseem hu ua load. Niaj hnub no PYG muab koj cov lus qhia ib kauj ruam los ntawm kauj ruam los xam cov peev txheej ntawm cov kab ntawv qhia los pab koj xaiv cov lus qhia tsim nyog tshaj plaws.
Kauj Ruam 1: Nkag siab hom Load
Ua ntej dhia mus rau hauv kev suav, nws yog ib qho tseem ceeb kom nkag siab txog ntau hom kev thauj khoom uas cov kab ntawv qhia yuav ntsib. Cov no tuaj yeem suav nrog cov khoom zoo li qub (lub zog tsis tu ncua), dynamic loads (lub zog sib txawv), shock loads (sudden force), thiab txawm tias lub sijhawm thauj khoom (torque). Kev paub txog cov hom kev thauj khoom tshwj xeeb cuam tshuam nrog koj daim ntawv thov yuav pab tau rau hauv kev suav kom raug.
Kauj Ruam 2: Sau cov ntaub ntawv tsim nyog
Tom ntej no, sau cov ntaub ntawv tseem ceeb uas xav tau rau kev xam kom raug. Cov ntaub ntawv no feem ntau suav nrog qhov hnyav ntawm qhov thauj khoom (lossis thauj khoom), lub zog siv, qhov kev ncua deb ntawm kev txhawb nqa, thiab lwm yam uas cuam tshuam rau lub peev xwm nqa, xws li acceleration lossis deceleration rog.
Kauj Ruam 3: Txiav txim siab qhov Dynamic Load Rating Factor
Qhov ntsuas dynamic load (C) yog qhov tseem ceeb hauv kev suav cov peev txheej ntawm lub loadlinear qhia. Cov neeg tsim khoom feem ntau muab tus nqi tsim nyog (f) uas sib haum rau cov kev teeb tsa tshwj xeeb ntawm cov kab ntawv qhia kab. Qhov ntsuas dynamic load (C0) yog txiav txim siab los ntawm kev muab cov dynamic load ntsuas (C) los ntawm qhov ua tau (f).
Kauj Ruam 4: Xam cov load thov
Txhawm rau xam cov khoom siv, ntxiv qhov hnyav ntawm lub nra (nrog rau lwm qhov ntxiv quab yuam) rau qhov ntsuas qhov hnyav (C0). Kev suav suav nrog acceleration thiab deceleration rog (yog tias muaj).
Kauj Ruam 5: Tshawb xyuas suav cov peev txheej load
Thaum cov ntaub ntawv thov raug txiav txim siab, nws yuav tsum muab piv rau cov chaw tsim khoom lub peev xwm load. Xyuas kom tseeb tias qhov suav load peev xwm tsis tshaj qhov chaw tsim khoom lub siab tshaj plaws tso cai load.
Kev xam cov load ntawm linear phau ntawv qhia yog ib qho yooj yim nam ntawm tsim mechanical system.Nrog rau hnub no PYG qhia, koj tuaj yeem txheeb xyuas qhov kev thauj khoom muaj peev xwm ntawm koj cov kab ntawv qhia kom tau raws li koj daim ntawv thov tshwj xeeb. Nco ntsoov xav txog qhov sib txawv ntawm cov loads, sau cov ntaub ntawv tsim nyog, txiav txim siab qhov sib txawv ntawm qhov load, xam cov khoom siv, thiab muaj peev xwm raws li qhov tshwj xeeb muab los ntawm cov chaw tsim khoom. Los ntawm ua tiav cov kauj ruam saum toj no, koj tuaj yeem ua kom zoo dua qhov kev ua tau zoo thiab lub neej ntawm cov ntawv qhia linear, uas thaum kawg ua rau kev ua haujlwm zoo ntawm cov tshuab tshuab. Yog tias koj muaj lwm yam kev txhawj xeeb, thovtiv tauj peb, peb cov neeg siv khoom platform yuav teb koj raws sijhawm.
