Yuav ua li cas rail pads tiv thaiv steel lem los ntawm kev cuam tshuam?
Hlau railstshwm indestructible. Txawm li cas los xij, hauv microscopic mechanical analysis, high-frequency shock waves generated at the moment of wheel-rail contact is the first culprits makes rail breaking because of metal fatigue. Raws li ib leeg elastic damping tivthaiv nyob rau hauv lub khiav system, lubrail ncoomuaj lub luag haujlwm tseem ceeb: txhawm rau hloov qhov kev cuam tshuam tsis zoo no rau hauv kev tswj hwm elastic deformation, yog li tiv thaiv cov qauv kev tsheb nqaj hlau.
Ua ntej, lub dissipation ntawm kev cuam tshuam lub zog cia siab rau viscoelastic zog ntawm cov khoom.Thaum lub log hla ntawm kev kub ceev, lub zog kinetic loj heev ua vertically ntawm txoj kev tsheb ciav hlau. Yog tsis muaj cushioning, lub zog no qhia txog sab hauv hauv txoj kev tsheb ciav hlau raws li kev poob siab tsis muaj zog, ua rau kev nthuav tawm ntawm micro- tawg.
Hauv kev tsim cov rail roj hmab ncoo, GNEE RAIL siv lub siab hysteresis poob yam ntxwv ntawm cov roj hmab ntuj. Qhov no tso cai rau lub ncoo hloov ib feem tseem ceeb ntawm txhua yam cuam tshuam lub zog rau hauv tshav kub thaum compression. Peb qhov chaw sib xyaw ua ke tswj xyuas qhov loj me me thiab kev faib tawm ntawm cov pa roj carbon dub ntxiv cov neeg ua haujlwm kom zoo -kho cov damping coefficient, ua kom lub ncoo teb sai sai rau kev cuam tshuam yam tsis ua kom muaj zog rov qab ntau dhau uas tuaj yeem ua rau kev puas tsuaj thib ob.

Qhov thib ob, kev txhim kho qhov kev ntxhov siab ntawm qhov chaw sib cuag yog qhov tseem ceeb rau kev tiv thaiv kev tsheb ciav hlau hauv paus tawg.Hauv kev teeb tsa tiag tiag, pob zeb pw tsaug zog inevitably muaj qhov tsis sib xws me me. Yog tias tsis muaj qhov hloov pauv tau ntawm lub tsheb ciav hlau elastic ncoo, taw tes sib cuag tshwm sim ntawm lub hauv paus kev tsheb nqaj hlau, ua rau muaj kev ntxhov siab hauv zos uas tshaj cov hlau tawm los txwv.
GNEE RAIL ntiav cov neeg ua haujlwm siab -cov txheej txheem txhaj tshuaj thiab compression molding los tswj cov thickness kam rau ua ntawm qib micron. Qhov zoo tshaj qhov chaw tiaj tus no ua kom lub ncoo ua kom nruj rau hauv qab txoj kev tsheb ciav hlau, diffusing cov ntsiab lus tseem ceeb ntawm cov khoom thauj mus rau hauv thaj chaw faib khoom, txo qis kev ntxhov siab ntawm txoj kev tsheb ciav hlau.
Tsis tas li ntawd, cov kab sib txawv muaj qhov sib txawv rau qhov cuam tshuam, xav tau cov ntaub qhwv nrog cov khoom zoo li qub - rau - qhov sib txawv nruj nruj.GNEE RAIL lub chaw kuaj mob yog nruab nrog Dynamic Mechanical Analysis (DMA) cov cuab yeej muaj peev xwm simulating loading zaus ntawm ntau lub tsheb ciav hlau ceev. Txawm hais tias rau siab - cov kab ceev uas xav tau siab elasticity lossis hnyav - cov kab tsheb thauj mus los xav tau lub zog siab, peb tuaj yeem ua kom zoo dua qhov kev vibration damping tsis tau los ntawm kev kho cov formulation hardness ntawm txoj kev tsheb ciav hlau.
Thaum kawg, lub durability ntawm qhov kev tiv thaiv no nyob ntawm kev qaug zog.Ib txoj kev tsheb ciav hlau tsim nyog yuav tsum rov qab mus rau nws qhov qub qub tom qab ntau lab lub voj voog compression. GNEE RAIL's Hoobkas cov qauv xav kom cov khoom kom dhau 3-million-cycle fatigue test uas tsis muaj cracking lossis deformation mus tas li. Qhov kev tswj xyuas zoo no ua kom ntseeg tau tias lub ncoo ua haujlwm ua "mos tsaws" platform rau txoj kev tsheb ciav hlau thoob plaws nws lub neej tag nrho, ua kom muaj txiaj ntsig zoo rau kev pab cuam lub neej ntawm tag nrho cov kab ke.
GNEE RAILyog nruab nrog rail ncoo cov kab ntau lawm rau 130sets ntawm cov cav tov, rau tag nrho cov txheej txheem ntawm kev txhaj tshuaj, refining roj hmab, sulfuration, molding thiab tshuaj xyuas, thiab lwm yam. Peb muaj cov engineers feem ntau rau rail ncoo txoj kev loj hlob, tsim, ntau lawm thiab tshuaj xyuas, nrog txhua xyoo muaj peev xwm ncav cuag 2000, 000 daim.
