A rail ncooyog muab tso rau hauv nruab nrab ntawm lub tsheb ciav hlau thiab baseplate los yog sleeper. Rail ncoo yog qhia rau txoj kev tsheb ciav hlau fastening system vim nws cov resilience los yog viscoelasticity uas yuav siv tau nyob rau hauv kev cuam tshuam ntawm qaug zog tawg ntawm pw tsaug zog. Lub dynamic kev nyuab siab los ntawm lub log los yog kev tsheb nqaj hlau cuam tshuam los ntawm ob qho tib si tsis tu ncua thiab tsis xwm yeem txav yog attenuated.
Lub vibration damping kev ua tau zoo ntawm kev tsheb ciav hlau li cas?
Rail pads muab kev co zoo heev los ntawm kev siv cov ntaub ntawv xws li roj hmab thiab polyurethane kom nqus tau lub zog, hloov nws mus rau hauv tshav kub, txo kev hnav, txhim kho kev nplij siab, thiab txo qis suab nrov, nrog kev ua tau zoo los ntawm cov yam ntxwv tshwj xeeb nruj / damping thiab cuam tshuam los ntawm qhov kub thiab txias, ua softer pads feem ntau zoo dua rau hauv av -yug vibration tab sis yuav tsum tau ceev faj tuning.
Cov yam ntxwv tseem ceeb ntawm kev ua haujlwm
- Stiffness & Damping: Kev ua tau zoo yog nyob ntawm qhov nruj (shear modulus) thiab damping (tsis zoo), ob qho tib si sib txawv nrog kub, load, thiab zaus.
- Softer Pads: Feem ntau txo hauv av- ua rau muaj kev vibrations (txog 10dB hauv qee thaj tsam) thiab kev tsheb ciav hlau corrugation tab sis tuaj yeem ua rau muaj kev sib haum xeeb ntau dhau yog tias muag muag heev.

- Stiffer Pads: Ua tau zoo dua ntawm kev txo cov kev tsheb ciav hlau hauv qee qhov ntau zaus tab sis kis tau ntau dua.
- Kub: cuam tshuam rau ob qho tib si txhav thiab damping; cov ntaub ntawv zoo li cork- cov khoom siv roj hmab ua haujlwm txawv dua li cov roj hmab ntshiab.
Txoj kev tsheb ciav hlau ua haujlwm li cas?
- Energy Absorption: Cov ntaub ntawv hloov kinetic zog (vibrations) rau hauv tshav kub, dissipating nws.
- Elasticity: Muab qhov tseem ceeb elasticity, tso cai rau nruab nrab deformation nyob rau hauv load, uas txo qhov cuam tshuam.
- Load Distribution: Txhim kho kev thauj mus los thiab kev faib tawm thoob plaws lub txaj pw, tiv thaiv lub hauv paus.
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.
