Rail padsyog cov elastic polyurethane mats uas yog cuam tshuam ntawm steel rails thiab railway sleepers los tiv thaiv lub sleeper saum ntawm hnav thiab cuam tshuam.
Yuav ua li cas lub tsheb ciav hlau elastic ncoo txo kev co thiab suab nrov?
Rail elastic pads txo kev vibration thiab suab nrov los ntawm kev ua raws li kev vibration dampers: lawv cov ntaub ntawv elastomeric (xws li roj hmab lossis polyurethane) nqus lub zog kinetic los ntawm lub log -rail kev sib cuam tshuam, hloov nws mus rau hauv tshav kub, thaum tseem kis tau cov loads, tiv thaiv hlau- ntawm -hlau kev sib cuag, thiab decoupling vibrations ua rau lub neej ntev dua, kev caij tsheb kauj vab.
Lawv ua haujlwm li cas:
- Energy Absorption & Damping: Cov khoom siv elastic (cov roj hmab, polyurethane) muaj cov khoom ua haujlwm siab, lub ntsiab lus nws absorbs lub zog vibrational generated los ntawm lub log, hloov mus rau hauv tshav kub, uas dissipates harmlessly es tsis txhob hloov mus rau lub khiav.
- Kev sib cais ntawm kev vibration: Los ntawm kev tso lub ncoo ntawm txoj kev tsheb ciav hlau thiab cov neeg pw tsaug zog (lossis baseplate), lawv tsim qhov tsis muaj, tiv thaiv kev vibrations los ntawm kev txav mus rau hauv ballast, subgrade, thiab ib puag ncig ib puag ncig, txo cov qauv- ua suab nrov.
- Load Distribution: Pads kis tau cov concentrated load los ntawm txoj kev tsheb ciav hlau hla ib cheeb tsam loj ntawm cov neeg pw tsaug zog, txo kev ntxhov siab, tiv thaiv kev hnav, thiab tiv thaiv ob qho tib si rail fasteners thiab sleepers los ntawm kev puas tsuaj.
- Txo cov hlau sib cuag: Lawv ua raws li lub hauv ncoo, nres ncaj qha, tsis muaj suab nrov hlau- rau- hlau sib cuag ntawm cov khoom, uas txo qis siab - zaus suab nrov thiab hnav.
- Resilience & Longevity: High- cov ntaub qhwv zoo tuav lawv cov khoom elastic nyob rau hauv tas li compression thiab sib txawv kub, ua kom ntseeg tau zoo ib yam thiab txuas lub neej ntawm cov qauv khiav.
Yuav ua li cas lub suab nrov txo cov nyhuv ntawm rail pads ntsuas?
Rail ncoo suab nrov txo yog ntsuas los ntawm kev ntsuam xyuasTrack Decay Rate (TDR)(kev vibration damping hauv dB/m) siv cov cuab yeej tshwj xeeb ntawm kev sim lem, tom qab ntawd siv cov qauv los txhais TDR thiab pad zog (qhov tawv nqaij, qhov tsis zoo) rau hauv kev kwv yeesradiated suab nrov txo(dB) nyob rau hauv tiag -lub ntiaj teb no tej yam kev mob, txiav txim siab lub tsheb ciav hlau ceev thiab kub. Cov txheej txheem tseem ceeb suav nrog kev sib piv cov qib vibration ua ntej / tom qab kev teeb tsa los yog sivKev ntsuas suab nrovnyob rau hauv anechoic teeb tsa kom pom lub hwj chim acoustic, tag nrho cov validated los ntawm software thiab tiag - teb kev xeem.
Cov txheej txheem ntsuas tseem ceeb
- Track Decay Rate (TDR) Kev Ntsuas:
Txoj kev: Accelerometers ntsuas rail vibration teb rau lub impulse los yog dynamic load (zoo li lub tsheb ciav hlau dhau).
Metric: TDR ntsuas qhov nrawm nrawm nrawm npaum li cas hauv ib lub 'meter' (dB / m) nyob rau hauv cov kab ntau zaus, raws li tau hais los ntawm cov qauv zoo li EN 15461:2008+A1: 2010.
Daim ntawv thov: TDR siab dua txhais tau hais tias ua kom zoo dua qub thiab suab nrov tsawg.
- Kev ntsuas suab nrov:
Txoj kev: Siv ob lub microphones los ntsuas lub suab nrov dhau ntawm qhov chaw kaw qhov chaw (rail) kom pom tag nrho lub zog acoustic, suppressing suab nrov tom qab.
- Comparative Field Tests:
Txoj kev: Ntsuas tag nrho cov suab nrov (feem ntau A- hnyav dB) ntawm ib qhov chaw nrog cov ntaub ntawv txheem, tom qab ntawd nruab cov tsheb ciav hlau tshiab thiab ntsuas kom pom qhov sib txawv (xws li, 2-3 dB txo).
Vim li cas railway pads tsim nyog nyob rau hauv railway systems?
Rail pads yog qhov tseem ceeb rau kev faib cov tsheb ciav hlau thauj khoom, kev cuam tshuam rau kev sib tsoo, txo cov suab nrov thiab kev co, tiv thaiv cov neeg pw tsaug zog los ntawm kev hnav, thiab muab hluav taws xob rwb thaiv tsev, txhua yam uas ua rau lub neej ntev, txhim kho cov neeg caij tsheb, thiab ua kom lub cev muaj zog ntawm kev ua haujlwm zoo los ntawm kev ua lub luag haujlwm tseem ceeb ntawm cov hlau rail thiab cov pob zeb pw.
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.
