Dab tsi yog cov qauv rau rail elastic pads?
Rail elastic ncooCov qauv tsom rau cov khoom siv zoo (cov roj hmab nkauj xwb / cov khoom siv polymer), kev ua haujlwm (load, deflection, qaug zog, laus), qhov ntev, thiab cov tsos, tswj hwm los ntawm cov kev tshwj xeeb xws li Is Nrias teb IRS -T-55 lossis SNCF / DB cov qauv, kom ntseeg tau tias lawv daws cov kev ntxhov siab ntau zaus, kev vibration, thiab ib puag ncig kev nyab xeeb rau kev taug qab, nrog kev hloov pauv rau hnyav / kub sib tw hauv nroog rail.

Lub luag haujlwm ntawm txoj kev tsheb ciav hlau yog dab tsi?
Lub railway ncoo lub luag haujlwm tseem ceeb yog nqus cov kev poob siab thiab kev vibrations los ntawm cov tsheb ciav hlau hla, tiv thaiv cov qauv khiav (sleepers thiab ballast) los ntawm hnav, qaug zog, thiab kev puas tsuaj thaum txo suab nrov thiab txhim kho cov neeg caij tsheb los ntawm kev cuam tshuam cushioning thiab faib cov log loads thoob plaws cheeb tsam. Cov ntaub qhwv elastic no, muab tso rau nruab nrab ntawm txoj kev tsheb ciav hlau thiab cov neeg pw tsaug zog, txhim khu kev ruaj ntseg, muab hluav taws xob rwb thaiv tsev, thiab txuas ntxiv lub neej ntawm tag nrho cov tsheb ciav hlau.
Ntev npaum li cas yog ib txoj hlua elastic pad?
Rail elastic pad thickness sib txawv los ntawm daim ntawv thov, feem ntau yog li ntawm 4.5 hli mus rau 20 hli lossis ntau dua, nrog cov tuab tuab xws li 6 hli, 7 hli, 8-12 hli rau kev kub ceev, thiab 12-20 hli rau cov khoom thauj hnyav, muab cushioning, vibration dampening, thiab hnav kev tiv thaiv ntawm kev tsheb nqaj hlau thiab kev pw tsaug zog.
- Load & Vibration: Thicker pads muab kev thauj khoom zoo dua thiab kev co kev nqus (co tswj) rau cov tsheb hnyav.
- Hom Kev Taug Kev: Cov neeg pw tsaug zog feem ntau siv cov ncoo tuab (xws li 4.5mm) rau elasticity.
- Khoom siv: Cov khoom sib txawv (rubber, EVA, yas) thiab cov qauv tsim (xws li, qaum- ntxiv dag zog) muaj qhov sib txawv ntawm cov qauv tuab.
