Dab tsi yog cov haujlwm ntawm rail rubber pads?
Rail roj hmab padsua ntau yam haujlwm tseem ceeb hauv txoj kev tsheb ciav hlau, cuam tshuam ncaj qha rau kev ua haujlwm, kev ruaj ntseg, thiab kev nyab xeeb ntawm kev khiav haujlwm.
Lub ncoo lub luag haujlwm tseem ceeb yog kev tswj xyuas lub zog vibration thiab cuam tshuam kev nqus. Thaum lub log tsheb ciav hlau hla dhau ntawm txoj hlua, lawv tsim cov kev cuam tshuam tsis tu ncua thiab kev vibrations. Siv cov khoom viscoelastic ntawm cov ntaub ntawv polymer, cov ntaub qhwv no hloov lub zog ntawm lub zog rau hauv cov cua sov kom maj mam dissipation. Lub zog hloov dua siab tshiab no txo qis qhov kev vibration siv rau cov neeg pw tsaug zog thiab lub txaj ballast, tsis yog tsuas yog tiv thaiv cov neeg pw tsaug zog los ntawm kev qaug zog, tab sis kuj tseem muaj txiaj ntsig zoo rau kev nthuav tawm ntawm cov qauv suab nrov mus rau ib puag ncig ib puag ncig, yog li txhim kho kev nplij siab ntawm txoj kab.

Thib ob, cov ntaub qhwv ntsej muag ua lub luag haujlwm tseem ceeb hauv kev xa khoom thauj thiab kev ua kom zoo rau kev ntxhov siab. Lub log -rail contact point ua rau muaj kev ntxhov siab heev. Los ntawm nws tus kheej elastic deformation, lub ncoo disperses no concentrated load tshaj ib tug loj sleeper bearing cheeb tsam. Qhov no zoo heev txo cov kev sib cuag compressive kev nyuaj siab ntawm qhov chaw pw tsaug zog, tiv thaiv pob zeb los ntawm kev tawg lossis tawg, thaum tseem pab tswj kom ntev - lub sij hawm ruaj khov ntawm kev taug qab geometry thiab txo cov kev xav tau kev saib xyuas niaj hnub.
Hauv cov kab hluav taws xob hluav taws xob, cov ntaub qhwv lub rwb thaiv tsev thiab kev tiv thaiv hluav taws xob yog qhov tseem ceeb heev. Cov khoom nws tus kheej muaj siab ntim resistivity, tsim ib tug txhim khu kev qha rwb thaiv tsev barrier ntawm lub tsheb ciav hlau thiab pw tsaug zog. Qhov no ua kom muaj kev sib kis tau zoo ntawm cov kab hluav taws xob hluav taws xob, tsim lub hauv paus rau kev ua haujlwm ntawm lub tsheb ciav hlau tswj cov tshuab (xws li cov teeb liab thiab thaiv cov tshuab) thiab ncaj qha ntsig txog kev nyab xeeb ntawm kev ua haujlwm.
Tsis tas li ntawd, cov pads muab cov haujlwm pabcuam ntawm ib puag ncig sealing thiab kev them nyiaj hloov kho. Nruab nruab nrab ntawm lub hauv paus kev tsheb nqaj hlau thiab cov neeg pw tsaug zog, lawv tuaj yeem, rau qee qhov, thaiv kev nkag mus ntawm cov dej nag, plua plav, thiab lwm yam txawv teb chaws, ua rau qeeb ntawm cov ntaub ntawv pw tsaug zog. Tib lub sijhawm, cov ntaub qhwv lub elasticity tso cai rau kev ncua ntev ntev thiab kev cog lus ntawm txoj kev tsheb ciav hlau vim qhov kub thiab txias hloov, buffering qhov tshwm sim thermal stresses thiab tiv thaiv ntau dhau deformation los yog tiam ntawm cov txheej txheem ntxiv hauv lub zog.
Nyob rau hauv cov ntsiab lus, roj hmab rail pads yog indispensable "elastic pob qij txha" nyob rau hauv txoj kev khiav. Los ntawm lawv cov kev ua haujlwm zoo txhua yam thiab hluav taws xob, lawv ua kom qhov du, ruaj khov, thiab kev nyab xeeb ntawm txoj kev nyob rau hauv ntev - lub sij hawm dynamic loads.GNEE RAILmuab tag nrho cov khoom siv roj hmab rail pad. Peb tuaj yeem pom zoo kom sib piv cov kev daws teeb meem raws li cov kab tsim tshwj xeeb, kev ua haujlwm, thiab kev xav tau ib puag ncig, nrog rau cov kev pabcuam kev sib tham tsis tu ncua.
