UIC txhais li cas ntawm kev kub ceev tsheb ciav hlau?
Hauv kev tsim kho tsheb ciav hlau, UIC (International Union of Railways) txhais siab -kev tsheb ciav hlau ceev (HSR) raws li kev tsheb ciav hlau uas khiav ceev ntawm 250 km / h lossis siab dua ntawm cov kab uas tau tsim tshiab, thiab nyob ib ncig ntawm 200 km / h ntawm cov kab uas tau hloov kho dua tshiab, muab qhov kev tsim kho vaj tse, dov Tshuag, kev taw qhia, thiab kev saib xyuas kom tau raws li cov qauv kev ua haujlwm siab{3}. Qhov no txhais tau hais tias kev siab - kev tsheb ciav hlau ceev tsis yog txiav txim siab los ntawm kev tsheb ciav hlau ceev ib leeg, tab sis los ntawm tag nrho cov peev txheej, suav nrog cov qauv kev tsheb nqaj hlau, qib kev tsheb nqaj hlau, kev sib tsoo tshuab, vuam zoo, thiab cov duab kos duab.
Hauv cov haujlwm thoob ntiaj teb tsim los ntawm UIC thiab EN cov qauv, cov chaw muag khoom xws li GNEE RAIL tsis yog tsuas yog ua raws li cov hlua hlau tab sis kuj ua tiav cov kev daws teeb meem thiab kev txhawb nqa los xyuas kom meej tias cov kab khiav ua tau raws li siab - cov txheej txheem ua haujlwm ceev.
UIC txuas siab - kev tsheb ciav hlau ceev li cas rau cov qib rail steel thiab cov qauv kev taug qab?
Txawm hais tias UIC keeb kwm tau tsom mus rau kev sib koom tes thiab kev ua haujlwm, kev ua haujlwm siab - cov phiaj xwm kev tsheb ciav hlau niaj hnub ua rawsTS EN 13674-1 rail qauv, uas yog ua raws li UIC profiles. Cov qauv no qhia tsis tau tsuas yog rail geometry tab sis kuj steel qib, mechanical zog, thiab manufacturing zoo. Rau siab - kev pab cuam ceev, rail hlau yuav tsum ua kom pom kev tiv thaiv siab rau hnav, yas deformation, thiab qaug zog tawg, tshwj xeeb tshaj yog nyob rau hauv lub qag nquag loads thiab thermal stress los ntawm ntev welded ntsia.
Cov khoom siv feem ntau siv rau ntawm UIC- cov kab profile rau siab - nrawm thiab hnyav- daim ntawv thov muaj xws li:
| Qib Steel | Kev siv yam | Yam ntxwv |
|---|---|---|
| R260 | General mainline | Balanced zog thiab toughness |
| R350 HT | High -kev nrawm nrawm, hnyav thauj | Siab hardness, txhim kho hnav tsis kam |
| R370CrHT | Cov chaw hnav khaub ncaws hnyav heev | Ua kom qaug zog thiab tiv thaiv kev ntxhov siab |
Hom ntawm UIC Rail
UIC (International Union of Railways) cov qauv kev tsheb ciav hlau feem ntau, feem ntau UIC54 (54E1) thiab UIC60 (60E1), muaj ntau, hnyav- lub luag haujlwm rails paub txog kev ruaj ntseg, nrog UIC60 feem ntau siv rau siab - cov kab nrawm vim nws qhov hnyav dua, thaum lwm qhov kev hloov pauv tau siv tshwj xeeb xws li kev tsheb ciav hlau (eg60A) (eg. UAS 33). Cov lej lej no (xws li 54 lossis 60) qhia lawv qhov hnyav hauv ib 'meter' (piv txwv li, 54 kg / m lossis 60 kg / m), muab qhov loj me rau kev tsim qauv.
Common UIC Rail Hom
- UIC54 (54E1): Cov qauv kev tsheb ciav hlau nrov heev, muab kev hnav zoo thiab ruaj khov rau kev siv tsheb ciav hlau dav dav.
- UIC60 (60E1): hnyav dua UIC54, haum rau siab dua qag loads, hnyav -haul, thiab siab - kab ceev, featuring lub taub hau tuab thiab dav ko taw kom zoo dua load faib.
- UIC50: Tus qauv qub, sib dua, tseem siv tab sis feem ntau hloov los ntawm UIC54 lossis UIC60 rau cov ntawv thov niaj hnub.
