Extruded Aluminium Profile rau Railway Transit

Aluminium yog siv los ua txhua yam ntawm lub tsheb kauj vab mus rau lub nkoj. Cov hlau no ua rau tib neeg taug kev ntawm kev nrawm nrawm, hla dej hiav txwv, ya saum ntuj, thiab txawm tawm hauv ntiaj teb. Kev thauj mus los kuj tseem siv cov txhuas feem ntau, suav txog 27% ntawm tag nrho cov khoom siv. Rolling stock builders tab tom nrhiav lub teeb yuag tsim thiab tailored manufacturing, thov rau structural profiles thiab sab nrauv lossis sab hauv. Aluminium carbody tso cai rau cov tuam txhab txiav tawm ib feem peb ntawm qhov hnyav piv rau cov tsheb steel. Hauv kev thauj mus los sai thiab suburban rail systems uas cov tsheb ciav hlau yuav tsum nres ntau, kev txuag tseem ceeb tuaj yeem ua tiav raws li qhov xav tau tsawg zog rau kev nrawm thiab nres nrog cov tsheb txhuas. Tsis tas li ntawd, cov tsheb aluminium yog yooj yim dua los tsim thiab muaj cov khoom tsawg dua. Lub caij no, txhuas hauv tsheb txhim kho kev nyab xeeb vim nws yog ob qho tib si lub teeb thiab muaj zog. Aluminium tshem tawm cov pob qij txha los ntawm kev tso cai rau hollow extrusion (tsis yog ib qho kev tsim ob-plhaub daim ntawv), uas txhim kho tag nrho rigidity thiab kev nyab xeeb. Vim nws qhov nruab nrab ntawm lub ntiajteb txawj nqus thiab qis qis, aluminium txhim kho txoj kev tuav, nqus lub zog thaum sib tsoo, thiab ua kom luv braking nrug.
Nyob rau hauv qhov kev ncua deb rail systems txhuas yog dav siv nyob rau hauv kev kub ceev tsheb ciav hlau systems, uas tau pib ua tswvcuab en masse nyob rau hauv lub 1980s. Kev kub ceev tsheb ciav hlau tuaj yeem ncav cuag qhov ceev ntawm 360 km / h thiab ntau dua. Tshiab kev kub ceev rail technologies cog lus ceev nyob rau hauv ntau tshaj 600 km / h.

Aluminium alloy yog ib qho ntawm cov ntaub ntawv tseem ceeb siv hauv kev tsim kho lub cev, muaj:
+ Lub cev sab (sab phab ntsa)
+ ru tsev thiab pem teb panels
+ Cant rails, uas txuas hauv pem teb ntawm lub tsheb ciav hlau mus rau sab phab ntsa
Thaum lub sij hawm qhov tsawg kawg nkaus phab ntsa thickness ntawm txhuas extrusion rau lub tsheb lub cev yog ze li ntawm 1.5 hli, qhov max dav yog mus txog 700mm, thiab lub siab tshaj plaws ntev ntawm txhuas extrusion yog mus txog 30mtrs.
