Raws li peb txhua tus paub,hlau hollow seemyog ib yam khoom siv rau kev tsim kho vaj tse uas siv ntau rau cov qauv hlau. Koj puas paub tias muaj pes tsawg daim ntu ntawm cov qauv hlau siab? Cia peb saib hnub no.
1, Axially ntxhov siab tswv cuab
Lub zog axial feem ntau yog hais txog lub zog axial lossis axial siab ntawm cov tswv cuab, uas yog qhov yooj yim tshaj plaws ntawm cov tswv cuab.
2. Cov tswv cuab Flexural
Cov khoom siv khoov feem ntau raug rau lub zog khoov thiab lub zog hla, feem ntau yog cov ntoo khaub lig. Cov duab seem dav dav ntawm cov khoom no yog I-puab. Kuj tseem muaj cov duab groove, trapezoid thiab Z-puab thaum lub zog me. Thaum lub zog loj, cov duab thawv tuaj yeem siv tau. Nws yuav tsum nco ntsoov tias thaum xam lub zog ntawm cov khoom no, tsis yog tsuas yog lub zog khoov xwb, tab sis kuj tseem yuav tsum xam lub zog shear thiab kev ruaj khov.
3, Cov tswv cuab uas muaj qhov tsis sib xws
Feem ntau cov khoom uas muaj kev ntxhov siab eccentric tsis yog tsuas yog raug kev txom nyem los ntawm lub zog axial xwb, tab sis kuj raug kev txom nyem los ntawm lub zog khoov thiab lub zog shear transverse. Cov khoom uas muaj kev ntxhov siab eccentric feem ntau muaj ob hom seem zoo li tus ntoo khaub lig thiab tus duab I. Thaum lub nra hnyav ntau, cov khoom uas zoo li tubular thiab lub thawv kuj siv tau. Cov khoom uas muaj kev ntxhov siab eccentric muaj ntau daim ntawv seem, thiab kev suav yog qhov nyuaj dua li ob lub khoom thawj zaug, uas yog, los xam lub zog, tab sis kuj los xyuas qhov ruaj khov.
Cov khoom tseem ceeb ntawm cov qauv hlau siab yog cov ntoo khaub lig thiab cov kem. Nws yog qhov tseeb tias cov duab ntawm cov ntoo khaub lig thiab cov kem kuj sib txawv heev, thiab muaj ntau hom. Txawm hais tias cov duab ntawm cov seem sib txawv heev, lawv zoo sib xws hauv cov ntsiab cai tsim. Cov duab ntawm cov ntoo khaub lig tsuas yog I-puab thiab lub thawv xwb. Cov duab ntawm cov kem tuaj yeem muab faib ua ob pawg, ib qho yog seem khov, uas yog I-puab thiab duab hla. Qhov thib ob yog seem khoob, uas yog tubular thiab lub thawv.
Los ntawm qhov pom ntawm kev tsim khoom, qee zaum, cov tswv cuab ua los ntawm ib lub qauv hlau tsis tuaj yeem ua tau raws li qhov yuav tsum tau tsim. Yog li ntawd, nws yog qhov tsim nyog los txais yuav lwm daim ntawv, uas yog, daim ntawv sib xyaw ua ke. Rau cov khoom sib xyaw ua ke, nws tsuas yog txwv rau cov khoom sib xyaw ua ke raws li kev tsim kho tam sim no. Cov khoom sib xyaw ua ke feem ntau tuaj yeem muab faib ua ob pawg, ib qho yog cov khoom ua los ntawm cov hlau seem, thiab lwm qhov yog cov khoom sib xyaw ua ke ua los ntawm cov hlau seem thiab phaj hlau lossis ua tiav los ntawm phaj hlau. Hauv cov qauv vuam, cov khoom sib xyaw ua ke ua los ntawm cov hlau phaj muaj kev ywj pheej zoo. Rau cov neeg tsim qauv, nws yooj yim heev los xaiv cov khoom sib xyaw ua ke no, txawm tias nws yog qhov ntev sab nraud lossis daim ntawv seem ntawm cov khoom. Kev siv ntau yam thev naus laus zis vuam tsis siv neeg hauv xyoo tas los no kuj tau tsim cov xwm txheej zoo rau ntau yam khoom uas txais yuav daim ntawv ntawm cov khoom sib xyaw ua ke.
