1. Lub luag haujlwm tseem ceeb ntawm txoj kev tsheb ciav hlau yog dab tsi?
Railway rails yog lub hauv paus ntsiab lus ntawm kev tsheb ciav hlau kev tsheb ciav hlau, ncaj qha bearing lub ntsug siab thiab lateral impact force los ntawm lub tsheb ciav hlau log. Lawv coj cov tsheb ciav hlau raws li kev taw qhia ruaj khov thiab hloov cov khoom thauj mus rau cov neeg pw tsaug zog thiab ballast. Rails yuav tsum muaj lub zog siab, hnav tsis kam, thiab qaug zog ua haujlwm kom ntseeg tau ntev - lub sijhawm ua haujlwm ruaj khov. Cov ntaub ntawv kev tsheb ciav hlau muaj xws li siab - carbon steel lossis hlau alloy, nrog cov ntoo hla -sectional shapes optimized los faib kev ntxhov siab.
2. Dab tsi yog hom kev tsheb ciav hlau sib tsoo?
Suav railways feem ntau siv50kg / m, 60kg / m, thiab75kg / mrails, nrog 60kg / m rails yog feem ntau siv. Thoob ntiaj teb, cov qauv sib xws suav nrogUAS 54, UAS 60(European standard), thiabAREMA(American txuj). Ntau hom kev tsheb ciav hlau tsim nyog rau kev sib txawv qag loads; Piv txwv li, hnyav - txoj kev tsheb ciav hlau yuav tsum siab dua - lub zog 75kg / m rails.
3. Yuav ua li cas rau yav tom ntej txoj kev loj hlob ntawm txoj kev tsheb ciav hlau?
Siab dua - cov ntaub ntawv muaj zog:eg, bainitic steel.
Kev soj ntsuam ntse: Embedded sensors rau lub sijhawm tiag tiag - kuaj mob.
Eco-tsim: Cov khoom siv rov ua dua tshiab thiab qis - cov suab nrov nrov.
4. Txoj kev tsheb ciav hlau raug cais li cas?
Kev puas tsuaj saum npoo: Sib tw, sib tw.
Sab hauv flaws: Cracks, voids.
Geometric deformation: Khoov, twisting.
18. Cov tsheb ciav hlau ntev npaum li cas?
Dedicated ntev - tsheb thauj mus losyog siv, nrog spacers ntawm txheej los tiv thaiv deformation. Kev txwv ceev thiab nres nres yog tswj hwm.
