Rail ncoo, los yog railway roj hmab ncoo, yog ib yam khoom muaj los txo cov kev co kis tau los ntawm cov ntsia hlau mus rau lub sleeper los yog subgrade.
Dab tsi yog qhov nyuaj ntawm lub tsheb ciav hlau?
Rail ncoo txhav txawv dav, los ntawm cov ntaub mos mos < 80 kN / mm rau cov tawv tawv> 150 kN / mm, ntsuas raws li kev tiv thaiv rau deformation, tab sis nws yog nonlinear, hloov nrog load (amplitude) thiab zaus, nrog rau cov ntaub ntawv xws li EPDM, TPE, thiab EVA muaj ntau yam sib txawv (xws li, 5 kPE ~ 1mm / 8mm) thiab siab -frequency stiffness feem ntau txawv ntawm qhov kev ntsuam xyuas zoo li qub.

Yuav ua li cas pad stiffness cuam tshuam lub durability ntawm txoj kab khiav?
Rail pad stiffness ho cuam tshuam taug qab durability:softer padsfeem ntau txo qis zog, txo qis kev ntxhov siab ntawm cov khoom, tiv thaiv ballast breakage, thiab ncua lub neej qaug zog, thaumtawv tawvtuaj yeem ua rau muaj kev vibration, txhais tau hais tias kev ntxhov siab ntawm cov fasteners (xws li clips), thiab cov yas yas, muaj peev xwm ua rau lub neej luv luv tab sis txwv kev tsheb ciav hlau. Qhov zoo tshaj plaws nruj sib npaug load faib, kev co damping, thiab tivthaiv kev nyuaj siab, nrog optimized pads (feem ntau softer nrog zoo damping) txo degradation, txhim kho kev khiav hauj lwm zoo, thiab txo cov kev xav tau ntawm kev tu.
Cov teebmeem ntawm Soft Rail Pads (Lower Stiffness)
- Txo Kev Nyuaj Siab & Hnav: Tshaj tawm cov khoom thauj zoo dua, txo qis kev sib cuag kev ntxhov siab ntawm ballast thiab pw tsaug zog, tiv thaiv kev tawg thiab deformation mus tas li.
- Dampens Vibrations: Absorbs cuam tshuam, txo siab - zaus vibrations thiab accelerations nyob rau hauv cov qauv khiav.
- Txhim kho lub neej qaug zog: txo qis kev ntxhov siab ntawm cov fasteners, txuas ntxiv lub neej qaug zog ntawm cov khoom xws li clips.
- Txo cov Rail Corrugation: softer nyob rau hauv - pw tsaug zog pads (USPs) muaj txiaj ntsig ntawm kev txo cov tsheb ciav hlau corrugation, ib qho teeb meem loj hnav, tshwj xeeb tshaj yog nyob rau hauv nkhaus.
- Muaj peev xwm Drawback: tuaj yeem ua rau muaj kev hloov tsheb ntau ntxiv thiab muaj suab nrov dua yog tias damping tsis txaus.
Cov teebmeem ntawm Stiff Rail Pads (Higher Stiffness)
- Txwv Rail Movement: Tightly khub txoj kev tsheb ciav hlau mus rau tus neeg pw tsaug zog, txwv kev tsheb ciav hlau kev co tab sis ua rau tsaug zog ntxiv.
- Ua kom muaj kev ntxhov siab ntxiv: Intensifies txhais tau tias kev ntxhov siab thiab cov yas hauv cov clips, ua rau lawv lub neej qaug zog.
- Yuav Ua Rau Tsis Txaus Siab: Cov ntaub qhwv tawv tawv tuaj yeem xa cov suab nrov dua yog tias tsis ua ke nrog lwm cov khoom damping.
- Zoo dua rau Cov Teeb Meem Tshwj Xeeb: Hauv qee qhov qauv tsim (xws li ob -theem systems), lub ncoo sab sauv khov kho pab tswj lub suab nrov.
Raws li ib tug kws tshaj lij rail fastener chaw tsim tshuaj paus, GNEE RAIL tuaj yeem tsim ntau hom roj hmab rail pads nrog cov ntaub ntawv sib txawv, xws li roj hmab ntuj, EVA, HDPE thiab lwm yam. Nyob rau hauv railway fastening system, roj hmab rail pads feem ntau ntsia nruab nrab ntawm txoj kev tsheb ciav hlau thiab cov pob zeb railway sleepers.
