Technical Requirements For Rail Track
Lub zog: Rail lem yuav tsum tiv thaiv lub log load thiab kub hloov yam tsis muaj ntau tshaj qhov kev ntxhov siab thiab deformation txwv. Qhov no yuav tsum muaj lub zog txaus, toughness, thiab hnav tsis kam.
Roughness: Locomotives cia siab rau kev sib txhuam ntawm cov log thiab cov tsheb ciav hlau sab saum toj rau traction, yuav tsum muaj qhov ntxhib rail nto. Txawm li cas los xij, rau cov tsheb, kev sib txhuam ntau dhau ua rau muaj kev tiv thaiv, yuav tsum tau ua kom lub tsheb ciav hlau smoother. Sib npaug qhov tsis sib xws, cov ntsia hlau yuav tsum muaj qhov feem ntau du, nrog qee zaus xuab zeb yog tias xav tau rau lub log tsheb zoo dua adhesion.
Elasticity: Rail lem siv lawv cov tawv tawv los tiv thaiv kev khoov hauv qab lub log, tab sis qee qhov elasticity yuav tsum tau txo qis kev cuam tshuam thiab tiv thaiv hnav ntawm dov Tshuag thiab lem.
Tenacity: Muab qhov chaw sib txuas me me ntawm lub log thiab tsheb ciav hlau, thiab lub siab siab, txoj kev tsheb ciav hlau xav tau kom muaj zog txaus los tiv thaiv kev sib tsoo thiab hnav sai. Txawm li cas los xij, yuav tsum muaj qhov sib npaug kom tsis txhob muaj qhov hnyav hnyav uas tuaj yeem ua rau muaj kev puas tsuaj los ntawm kev cuam tshuam, yuav tsum muaj qee qhov tenacity hauv txoj kev tsheb ciav hlau.
