Vim li cas Qee Cov Rail Pads muaj cov pob txha lossis cov grooves?
Nyob rau hauv niaj hnub railway transit systems, nto tsim ntawm lubRail PadNws txawv heev, xws li los ntawm cov qauv tiaj tus mus rau complex profiles featuring cylindrical studs los yog longitudinal grooves. Qhov sib txawv ntawm qhov pom qhov sib txawv ncaj qha cuam tshuam rau cov kev xav tau ntawm kev ua haujlwm tshwj xeeb. Tshwj xeeb tshaj yog rau High-Speed Rail thiab suab nrov- rhiab hauv nroog cov phiaj xwm kev thauj mus los, geometric tsim ntawm qhov chaw zoo nkauj yog qhov tseem ceeb hauv kev txiav txim siab elasticity thiab kev co damping efficiency ntawm lub fastening system. Cov qauv tsim tshwj xeeb no yog qhov tseem ceeb tsim kho kom kov yeej cov kev txwv lub cev ntawm cov roj hmab, ua tiav kev ua haujlwm zoo dua qub thaum tswj cov khoom siv ntev.
Regulating Stiffness Los ntawm "Void Volume"
Cov khoom siv roj hmab muaj lub cev ntawm lub cev ntawm "volumetrically incompressible," txhais tau hais tias thaum lub tiaj tiaj tiaj yog raug rau qhov hnyav ntsug, nws tsis tuaj yeem ntim hauv ntim; nws yuav tsum tau muab tshem tawm tom qab. Yog tias qhov kev nthuav dav no raug txwv los ntawm qhov chaw sib cuag, qhov nruj ntawm lub ncoo nce ntau, ua rau nws poob nws lub peev xwm damping.
GNEE RAIL hais txog qhov no los ntawm kev sib txuas cov studs lossis grooves rau hauv lub ncoo saum npoo, tsim kom muaj "qhov chaw dawb" lossis "Void Volume" ntawm txoj kev tsheb ciav hlau thiab cov neeg pw tsaug zog. Thaum lub tsheb ciav hlau hla, cov roj hmab compressed tuaj yeem txav thiab deform rau hauv cov khoob no. Txoj kev no ntawm kev txo qis qhov tawv nqaij los ntawm kev hloov kho cov duab zoo tso cai rau lub ncoo kom pom qhov tsis tshua muaj zog nruj thiab ua haujlwm zoo heev, txawm tias thaum siv siab -hardness, anti- kev laus cov tebchaw.
Peb tau tsim ntau yam ntawm -kev ua tau zoo elastic rail pads rau nruj raws li qhov yuav tsum tau ua thiab ntau yam kev thov hauv cheeb tsam- los ntawm cov tsheb ciav hlau los ntawm cov qauv ntsuas kev tsheb ciav hlau mus rau cov kab hnyav hnyav, tshwj xeeb tshaj yog rau E- hom tsheb ciav hlau fastening systems thiab SKL hom tsheb ciav hlau fastening systems nrog cov khoom ntawm HDPE / EVA / Roj Hmab, raws li nram no.

Customization rau ntau yam kev xav tau
Los ntawm kev kho txoj kab uas hla, qhov siab, thiab qhov ceev ntawm cov studs lossis qhov tob ntawm cov grooves, peb tuaj yeem tswj cov ntaub qhwv lub "Dynamic{0}}rau-Static Stiffness Ratio." Piv txwv li, hauv High-Speed Rail tej yaam num, qis- nruj Studded Rail Pads feem ntau yuav tsum tau nqus siab- zaus vibrations thiab tiv thaiv lub ballast. Hloov pauv, nyob rau hauv hnyav- txoj kev tsheb ciav hlau, ib qho kev tsim grooved nrog me ntsis nruj dua yuav raug nyiam los tswj kev ntsuas kev ruaj ntseg. Qhov kev yooj yim geometric no tso cai rau Grooved Rubber Pad kom sib npaug ntawm cov khoom thauj -cov kabmob muaj peev xwm nrog kev sib cais ntawm kev co, cuam tshuam kev sib kis ntawm kev vibration nthwv dej mus rau cov subgrade thiab ib puag ncig cov qauv.
Mould Development thiab Manufacturing ntawm GNEE RAIL
Ua cov ntaub ntawv textured no yuav tsum muaj cov qauv siab tshwj xeeb hauv pwm precision thiab vulcanization txheej txheem. Kev ua tsis tiav vulcanization lossis qhov sib txawv ntawm qhov sib txawv hauv cov studs tuaj yeem ua rau qhov tsis sib xws thiab tsis ua haujlwm ntxov. GNEE RAIL muaj ib qho kev lag luam- ua cov pwm pwm qhov chaw muaj peev xwm thim rov qab- engineering complex geometric pwm raws li cov qauv UIC lossis AREMA. Peb siv Finite Element Analysis (FEA) kom siv tau qhov kev faib tawm ntawm kev ntxhov siab ntawm cov qauv stud, kom ntseeg tau tias txhua qhov High Resilient Pad tuav nws cov ntaub ntawv kev ncaj ncees tom qab ntau lab lub voj voog thauj khoom, muab kev txhawb nqa ruaj khov thiab ruaj khov rau txoj kev khiav.
Kev tsim cov Studded Rail Pad xav tau cov cuab yeej molding siab heev los xyuas kom meej tias txhua qhov stud yog tsim los tsim kom muaj kev sib txig sib luag. GNEE RAIL txaus siab rau nws tus kheej ntawm nws cov khoom siv dav dav ntawm cov pwm pwm tsim rau ntau yam qauv thoob ntiaj teb (xws li cov qauv tsim tshwj xeeb siv hauv Fabkis lossis Nyij Pooj rail systems). Txawm hais tias koj qhov project yuav tsum muaj qhov tshwj xeeb dynamic-rau- qhov sib piv qhov tawv nqaij zoo li qub los yog tus qauv zawj tshwj xeeb rau kev tso dej thiab damping, GNEE RAIL tuaj yeem tsim kho thiab tsim cov kev daws teeb meem.Tiv tauj pebtxhawm rau txhim kho koj txoj kev tswj kev vibration nrog peb cov ntaub ntawv qib siab studded.
