Dab tsi ua rau lub tshuab ziab khaub ncaws ntawm lub tshuab ntawv ua yuam kev?
1. Cov khoom siv thiab cov teeb meem kev siv tshuab: Tsis yog- cov menyuam sib dhos- qhov no yog qhov laj thawj tseem ceeb ntawm cov qauv; Yog hais tias ib los yog ntau dua rollers tsis sib npaug, lub tshuab ziab khaub ncaws yuav tsis tu ncua mus rau ib sab. Kev taw qhia qhov tsis ua haujlwm-kev ua haujlwm tsis zoo lossis ua tsis raug hauv pneumatic lossis hydraulic correctors, sensors, lossis huab cua xau hauv kab tuaj yeem ua rau kev taw qhia tsis ua haujlwm lossis ua haujlwm tsis raug. Cov teeb meem tensioning rau cov menyuam- txwv tsis pub txav los yog huab cua tsis sib xws ntawm qhov kawg ntawm cov tensioning cov menyuam ua rau tsis sib npaug ntawm cov ntaub, ua rau nws mus rau sab uas muaj zog dua. Cov khoom sib kis los yog hnav- cov ntaub so ntswg lossis cov ntawv tawg ntawm cov ntawv qhia chais lossis cov khoom kho tuaj yeem tsim qhov tsis sib xws; Lub tshuab nqus tsev vacuum anomalies (xws li cua xau) tuaj yeem ua rau qhov chaw nqus dej tsis txaus, rub cov ntaub tawm -khiav.
2.Cov teeb meem kev ua haujlwm thiab kev ua haujlwm: kev nro tsis zoo- nro ntau dhau ua rau ncab thiab deformation, thaum tsis txaus nro tsis muaj kev sib txhuam txaus; qhov tsis sib xws thaum lub sijhawm teeb tsa tuaj yeem ua rau taug qab qhov yuam kev thaum lub sijhawm ua haujlwm. Lub kaum sab xis qhwv tsis txaus- yog "wrap angle" (arc of contact) ntawm lub tshuab ziab khaub ncaws nyob ib ncig ntawm daim ntawv qhia yob me me dhau, kev sib txhuam yuav tsis txaus, cuam tshuam qhov kev ua tau zoo ntawm cov cuab yeej sib dhos. Kev qhia yob tsis raug cai- qhov sib nrug ntawm qhov sib txawv ntawm cov yob thiab cov yob uas nyob ib sab uas deviates los ntawm cov qauv khoom siv tuaj yeem ua rau muaj peev xwm kho tau. Kev noj tsis ruaj tsis khov lossis ceev- tsis sib xws- tshuab xa tawm ntawm cov ntaub so ntswg los yog qhov tsis sib xws ntawm kev pub ceev thiab lub tshuab ziab khaub ncaws ceev tuaj yeem ua rau tsis sib xws ntawm cov ntawv tshuab tshuab ziab khaub ncaws, ua rau muaj teeb meem nrhiav.
3.Qhov teeb meem tshwm sim rau lub tshuab ziab khaub ncaws nws tus kheej: Cov khoom tsis zoo -qee cov ntaub muaj zog tensile tsis zoo, ua rau muaj kev ncab ntau dhau los yog deformation thaum lub sijhawm ua haujlwm uas dhau ntawm cov cuab yeej hloov kho; Tsis tas li ntawd, kev tsim cov ntaub tsis sib xws (qhov twg ib sab hnyav dua li lwm qhov) tuaj yeem ua rau cov ntaub tuaj yeem txav mus rau sab hnyav dua thaum ua haujlwm. Seam teeb meem- seam tsis ncaj los yog muaj qhov tsis xws luag ncaj qha ua rau cov ntaub sib txawv ntawm nws txoj kev xav khiav. Kev sib raug zoo ntawm cov khoom tshiab thiab qub - tsis txaus txaus- nyob rau hauv nruab nrab ntawm cov ntaub tshiab thiab cov chais uas twb muaj lawm tuaj yeem ua rau muaj teeb meem taug qab. Nws raug nquahu kom kuaj xyuas lub seam thawj zaug: siv qhov taw qhia siv los xyuas seb lub seam tseem nyob ntawm nws qhov dav thaum lub sijhawm ua haujlwm; Yog hais tias ib qho kawg ntawm seam coj mus rau lwm qhov, nws qhia tau hais tias cov khoom siv misalignment. Yog hais tias lub seam zoo nkaus li zoo sib xws tab sis kev taug qab cov teeb meem tshwm sim, tshawb xyuas txhua qhov kev ua tau zoo li no. Cov teeb meem taug qab feem ntau yog sib cuam tshuam; Piv txwv li, tsis yog{10}} cov menyuam sib npaug tuaj yeem ua rau hnav, thiab qhov tshwm sim tuaj yeem ua rau cov ntaub ntawv taug qab ua haujlwm tsis zoo. Tsim kom muaj kev soj ntsuam zoo raws tu qauv uas npog cov khoom siv, cov txheej txheem, thiab cov ntaub nws tus kheej ua kom paub tseeb ntau qhov tseeb ntawm cov hauv paus hauv paus, yog li ua kom ruaj khov ntau lawm.
