Dab tsi yog txoj haujlwm ntawm txoj kev tsheb ciav hlau sib koom ua ke?
Ib txoj kev tsheb ciav hlau sib koom ua ke (lossis ntses phaj) txuas ob lub tsheb ciav hlau kawg, ua haujlwm tseem ceeb los tswj kev sib tw, ruaj khov, thiab txuas ntxiv hauv kev tsheb ciav hlau. Nws ua kom muaj kev ncaj ncees ntawm cov qauv, tswj cov thermal expansion / kev sib cog lus, thiab txhawb nqa lub log thaum ua kom muaj kev sib tw, kev nyab xeeb, txo qhov cuam tshuam ntawm cov tsheb ciav hlau ntawm txoj kev.
Lub luag haujlwm tseem ceeb ntawm Txoj Kev Rail Joint:
- Continuity ntawm tus qauv:Txuas ob txoj kev tsheb ciav hlau los tsim kom muaj kev sib txuas, du nto rau tsheb ciav hlau txav.
- Alignment Maintenance:Tuav txoj kev tsheb ciav hlau xaus rau hauv qhov tseeb kab rov tav thiab ntsug txoj hauj lwm kom tswj tau qhov ntsuas qhov deb.
- Expansion/Contraction Management:Tso cai rau kev nthuav dav thiab cog lus ywj pheej nrog kev hloov pauv kub, tiv thaiv kev taug qab buckling.
- Qhov cuam tshuam:Minimizes qhov cuam tshuam quab yuam ntawm lub log ntawm cov pob qij txha, tiv thaiv kev khiav ntawm kev puas tsuaj thiab txo qhov hnav.
- Hluav taws xob conductivity:Feem ntau siv nyob rau hauv cov teeb liab, qee cov pob qij txha ua kom muaj hluav taws xob txuas ntxiv txhawm rau txheeb xyuas cov tsheb ciav hlau txoj haujlwm.
Puas Yog Rail Joint Bar Failure tshwm sim?
Rail sib koom ua ke tsis ua haujlwm feem ntau tshwm sim los ntawm siab - lub voj voog qaug zog tshwm sim los ntawm huab cua, rov ua haujlwm tsis zoo ntawm lub tsheb ciav hlau lub log, sib xyaw ua ke los ntawm, lossis ua rau, taug qab cov qauv degradation zoo li xoob bolts, hnav rail xaus (batter), thiab tsis zoo ballast txhawb. Cov kev ntxhov siab no feem ntau ua rau cov kab nrib pleb los ntawm qhov nruab nrab ntawm lub qhov ntsia hlau los yog nyob rau ntawm txoj kab tsheb ciav hlau / lub hauv paus kev sib tshuam, ua rau muaj kev cuam tshuam ntau dua los ntawm ib puag ncig thiab thermal contraction.
Yam Tseem Ceeb thiab Mechanics ntawm Failure:
- Siab -Cycle Fatigue:Thawj hom kev ua tsis tiav, uas tau tsav los ntawm kev khoov tas li thiab cuam tshuam kev ntxhov siab, feem ntau qhia los ntawm kev qaug zog ntawm qhov chaw tawg.
- Dynamic Loading thiab cuam tshuam:Thaum cov log hla dhau qhov sib txawv ntawm cov ntsia hlau, qhov txav ntsug ua rau muaj kev cuam tshuam loj heev uas dhau lub zog ntawm cov khoom siv, tshwj xeeb tshaj yog raws li kev sib koom ua ke.
- Kev kho tsis zoo:Loose, hnav, los yog tsis muaj bolts thiab degraded ballast tso cai rau kev sib koom ua ke kom deflect ntxiv, nthuav qhov kev ntxhov siab ntawm cov tuav.
- Rail End Batter:Raws li kev tsheb ciav hlau xaus tsis zoo vim muaj kev cuam tshuam, lawv tsim cov kauj ruam uas ua rau muaj kev cuam tshuam zoo, ua rau kev sib koom ua ke degradation.
- Stress Concentration:Qhov kev ntxhov siab tshaj plaws tshwm sim ntawm qhov nruab nrab, tshwj xeeb tshaj yog nyob rau ntawm lub qhov ntsia hlau, ua rau cov kab nrib pleb uas nthuav tawm sab nraud.
- Thermal thiab Tensile Stress:Tsis tshua muaj kub, uas ua rau cov ntsia hlau sib cog lus thiab rub sib nrug, muab cov pob qij txha nyob rau hauv kev nruj nreem, txhim kho qhov muaj feem ntawm kev tawg.
- Manufacturing Defects/Residual Stresses:Residual stresses los ntawm kev tsim khoom tuaj yeem ua rau tawg pib.
Founded hauv 2008,GNEE RAILyog lub chaw tsim khoom lag luam thoob ntiaj teb thiab cov khoom lag luam ntawm cov khoom siv tsheb ciav hlau, tshwj xeeb hauv kev siab - zoorail ntses daim hlau(cov khoom sib koom ua ke / cov kab sib txuas) nrog lub peev xwm ntau lawm thiab kev pabcuam thoob ntiaj teb.
