Rail pads yog ib qho tseem ceeb ntawm txoj kev tsheb ciav hlau uas ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm cov tsheb ciav hlau. Rail ncoo yog ib txheej resilient uas zaum ntawm txoj kev tsheb ciav hlau thiab txoj hlua khi, ua cov khoom siv cushioning uas absorbs lub zog dynamic tsim los ntawm cov tsheb ciav hlau. Lub luag haujlwm tseem ceeb ntawm rail pads yog los txo cov kev cuam tshuam thiab kev vibration los ntawm cov tsheb ciav hlau hla, yog li tiv thaiv kev puas tsuaj rau cov tsheb ciav hlau thiab cov khoom nyob ib puag ncig.
Dab tsi yog qhov lees txais compressive deformation txwv rau kev tsheb ciav hlau pads?
Rail ncoo pom zoo deformation txwv tsom rau compression teeb (qhov siab mus tas li), feem ntau nyob rau hauv 30% rau cov roj hmab pads tom qab tshav kub, thiab nruj (yuav ua li cas quab yuam ntau npaum li cas deflection) uas txawv ntawm daim ntawv thov (piv txwv li, 80-150 kN / mm rau nruab nrab nruj). Cov kev txwv kom ntseeg tau tias lub ncoo khaws nws cov elastic cushioning, tiv thaiv kev khiav ntau dhau los yog muaj kev ntxhov siab ntxiv, nrog rau cov qauv uas yuav tsum tau muaj kev ntsuam xyuas mus tas li (xws li $\\le $ 25-30% tom qab laus) thiab load-deflection.
Factors Influencing Limits:
- Khoom siv: Roj Hmab, HDPE, lossis cov ntaub ntawv sib xyaw muaj qhov sib txawv ntawm kev ua haujlwm.
- Hom kab khiav: Siab-ceev, hnyav thauj, lossis cov kab metro yuav tsum muaj qhov sib txawv nruj / damping.
- Environmental Factors: Kub thiab kev laus (kev qaug zog) cuam tshuam rau txhav thiab teeb.
Ntau yam ntawm -kev ua tau zoo elastic rail pads tau tsim los rau cov kev xav tau nruj thiab ntau qhov chaw thov- los ntawm cov tsheb ciav hlau los ntawm cov qauv ntsuas kev tsheb ciav hlau mus rau cov kab tsheb hnyav, qhov no tshwj xeeb tshaj yog tsim rau E- hom tsheb ciav hlau fastening systems thiab SKL- hom kev tsheb ciav hlau fastening system nrog cov khoom siv ntawm HDPE/EVA/R.

Raws li ib tug kws rail fastener chaw tsim tshuaj paus,GNEE RAILtuaj 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.
