Ntau yam zoo li hauv kev lag luam pib, steel thiab aluminium yog cov khoom tseem ceeb siv hauv covkev tsim kho tsheb ciav hlau lub cev, nrog rau cov tsheb ciav hlau sideboards, lub ru tsev, pem teb panels thiab cant rails, uas txuas rau pem teb ntawm lub tsheb ciav hlau mus rau sidewall.Aluminium muab ntau cov txiaj ntsig rau cov tsheb ciav hlau ceev: nws qhov sib txheeb lub teeb piv rau cov hlau, yooj yim sib dhos vim qhov txo qis, thiab siab corrosion kuj.Txawm hais tias txhuas yog kwv yees li 1/3 qhov hnyav ntawm cov hlau, feem ntau cov khoom siv txhuas siv hauv kev lag luam thauj khoom yog li ib nrab ntawm qhov hnyav ntawm cov khoom siv hlau vim yog lub zog xav tau.
Aluminium alloys siv nyob rau hauv lub teeb yuag high-speed rail carriages (feem ntau yog series 5xxx thiab 6xxx, zoo li hauv kev lag luam pib, tab sis kuj series 7xxx rau siab zog yuav tsum) muaj tsawg ntom piv rau steel (tsis muaj kev cuam tshuam ntawm lub zog), nrog rau zoo heev formability. thiab corrosion kuj.Feem ntau cov alloys rau tsheb ciav hlau yog 5083-H111, 5059, 5383, 6060 thiab tshiab 6082. Piv txwv li, Nyiv lub siab ceev Shinkansen tsheb ciav hlau muaj feem ntau 5083 alloy thiab ib co 7075, uas yog nquag siv nyob rau hauv lub aerospace kev lag luam, thaum lub German. Transrapid siv feem ntau 5005 daim ntawv rau panels thiab 6061, 6063, thiab 6005 rau extrusion.Tsis tas li ntawd, aluminium alloy cables kuj tau nce ntxiv los ua ib qho kev hloov rau cov tsoos tooj liab-core cables hauv kev xa xov thiab kev teeb tsa.
Yog li ntawd, lub ntsiab kom zoo dua ntawm txhuas tshaj hlau yog kev ruaj ntseg qis zog noj nyob rau hauv high-ceev tsheb ciav hlau thiab muaj zog load peev xwm thauj, tshwj xeeb tshaj yog nyob rau hauv freight tsheb ciav hlau.Hauv kev thauj mus los sai thiab kev tsheb ciav hlau hauv nroog, qhov chaw tsheb ciav hlau yuav tsum nres ntau, kev txuag nyiaj tseem ceeb tuaj yeem ua tiav raws li kev siv hluav taws xob tsawg dua rau kev nrawm thiab nres yog tias siv cov txhuas wagons.Cov tsheb ciav hlau sib sib zog nqus, ua ke nrog lwm cov kev ntsuas zoo sib xws tuaj yeem txo qis kev siv zog txog li 60% hauv cov tsheb tshiab.
Qhov kawg-qhov tshwm sim yog tias, rau tiam tshiab ntawm lub regional thiab high-ceev tsheb ciav hlau, txhuas tau ntse hloov steel raws li cov khoom ntawm kev xaiv.Cov tsheb thauj neeg no siv qhov nruab nrab 5 tonnes ntawm txhuas ib lub wagon.Txij li qee cov khoom siv hlau tau koom nrog (xws li lub log thiab cov kabmob), xws li wagons feem ntau yog ib feem peb sib dua piv rau steel wagons.Ua tsaug rau kev txuag hluav taws xob, cov nqi pib ntau dua rau cov tsheb thauj khoom hnyav (piv rau cov hlau) tau rov qab los tom qab kwv yees li ob thiab ib nrab xyoo ntawm kev siv.Saib ua ntej, cov khoom siv carbon fiber ntau yuav ua rau muaj qhov hnyav dua.
