Teb Lub Peb Hlis 15, 2018. muaj qhov piv ntawm qhov yuam kev amplitude rau qhov zoo li qub deflection. Qhov ntau no feem ntau hu ua a magnification factor . Nws txhais tau hais tias lub amplitude ntawm yuam kev vibration tsab ntawv tsa suab nrog hwm magnification ntawm qhov zoo li qub deflection raws li kev ua haujlwm ntawm qhov sib piv.
Dhau li ntawm no, koj yuav nrhiav tau qhov magnification factor li cas?
Yog xam magnification , siv cov hauv qab no qauv : magnification = qhov siab ntawm daim duab ÷ los ntawm qhov siab ntawm qhov khoom. Txuas koj cov ntaub ntawv rau hauv qauv thiab daws. Yog tias koj cov lus teb ntau dua 1, qhov ntawd txhais tau tias daim duab yog loj . Yog tias koj cov lus teb nyob nruab nrab ntawm 0 thiab 1, daim duab me dua qhov khoom.
yuam kev vibration yog dab tsi? quab yuam kev vibration yog ib hom kev vibration koj a quab yuam rov qab siv rau lub tshuab tshuab. quab yuam kev vibration yog thaum alternating quab yuam ormotion yog siv rau lub tshuab tshuab, piv txwv li thaum lub tshuab ntxhua khaub ncaws co vim qhov tsis sib xws.
Ib yam li ntawd ib tug yuav nug, dab tsi yog lub xeev kev vibration?
khov kho - xeev kev vibration ['sted·ē ¦stātvī'brā·sh?n] (mechanics) Kev vibration nyob rau hauv uas lub tshaj tawm ntawm txhua particle nyob rau hauv lub system yog ib tug nruam lub sij hawm kom muaj nuj nqis.
Dab tsi yog dynamic magnifier?
1.0 Kev Taw Qhia. Dynamic magnification factor yog txhais raws li qhov ratio ntawm cov dynamic deflection ntawm txhua lub sij hawm mus rau qhov zoo li qub deflection uas yuav tau tshwm sim los ntawm staticapplication ntawm sab nraud load, uas yog siv nyob rau hauv specifications theload-time variation [1-3].

Lub tuam txhab muaj peev xwm ua kom tau raws li cov neeg siv khoom xav tau raws sijhawm yog hu ua Kev Ua Haujlwm Zoo, thaum ua haujlwm tau zoo yog lub tuam txhab muaj peev xwm xa khoom raws li tus neeg siv khoom xav tau nrog tsawg kawg ntawm cov khoom siv raw, kev ua haujlwm thiab tus nqi
Dab tsi yog qhov zoo tshaj plaws hauv kev tswj hwm kev lag luam?
Lus Txhais: Cov Tswv Yim Zoo Tshaj Plaws yog cov tswv yim ntawm cov tuam txhab tsim los txheeb xyuas lub tuam txhab txoj kev xaiv nrog rau cov kev taw qhia nws ua kom tiav nws cov hom phiaj. Yooj yim, nws cuam tshuam txog kev txiav txim siab xaiv cov phiaj xwm mus sij hawm ntev los ntawm cov txheej txheem muaj
Lub hauv paus ntsiab lus ntawm kev siv siab tshaj plaws thiab zoo tshaj plaws yog dab tsi?
Ib qho cuab yeej yuav tsum raug ntsuas raws li nws qhov siab tshaj plaws thiab siv tau zoo tshaj plaws. Lub ntsiab lus ntawm kev siv siab tshaj plaws thiab zoo tshaj plaws yog raws li hauv qab no: Tsim nyog, tsim nyog thiab raug cai siv cov av tsis muaj lossis kev txhim kho vaj tse, uas yog lub cev ua tau, kev txhawb nqa tsim nyog, muaj peev xwm ua tau nyiaj txiag, thiab qhov ntawd ua rau muaj txiaj ntsig siab tshaj plaws
Yuav ua li cas koj txiav txim siab qhov siab tshaj plaws thiab zoo tshaj plaws ntawm kev siv cov cuab yeej?
Cov cuab yeej yuav tsum raug ntsuas raws li nws qhov siab tshaj plaws thiab siv tau zoo tshaj plaws.
