Nrog rau txoj kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis thiab kev nrawm ntawm nroog loj, txuas hniav, ua ib feem tseem ceeb ntawm kev thauj mus los hauv nroog, niaj hnub tsim kho tshiab hauv lawv cov qauv tsim thiab kev tsim kho. Traditional steel txuas hniav yog dav siv vim lawv lub zog siab thiab tus nqi qis. Txawm li cas los xij, dhau sijhawm, cov teeb meem xws li corrosion thiab cov nqi kho mob siab maj mam tshwm sim. Tawm tsam cov keeb kwm yav dhau los no, cov khoom siv high-end aluminium alloy tau dhau los ua kev xaiv hloov pauv hauv kev tsim kho choj nrog lawv cov kev ua tau zoo tshwj xeeb.
Qhov zoo ntawm cov khoom siv aluminium alloy
Qhov zoo ntawm lub teeb yuag tsim
Qhov ntom ntawm aluminium alloy yog li 2.7 g / cm³, uas tsuas yog li 1/3 ntawm cov hlau. Lub teeb yuag no txhais li cas rau kev tsim choj thiab kev tsim kho? Ua ntej ntawm tag nrho cov, lub teeb yuag choj cov qauv tuaj yeem txo cov kev xav tau ntawm cov hauv paus, tso cai rau cov choj loj loj los tsim hauv thaj chaw uas tsis zoo geological. Qhov thib ob, cov qauv teeb pom kev zoo kuj tuaj yeem txo cov nqi tsheb thauj mus los thiab kev teeb tsa, uas yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau thaj chaw deb lossis qhov chaw uas muaj kev txwv tsawg. Tsis tas li ntawd, cov qauv teeb pom kev zoo kuj tuaj yeem pab txhim kho seismic kev ua tau zoo thaum muaj av qeeg vim tias qhov hnyav dua yuav txo qis inertial rog hauv av qeeg.
Qhov tseem ceeb ntawm corrosion kuj
Aluminium alloy cov ntaub ntawv tuaj yeem tsim cov oxide zaj duab xis ntom ntom hauv ib puag ncig ntuj. Cov oxide zaj duab xis no tuaj yeem thaiv qhov nkag ntawm cov dej noo thiab oxygen, yog li tiv thaiv cov khoom los ntawm corrosion. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv kev tsim kho choj, vim cov choj feem ntau raug rau cov ntsiab lus thiab yuav tsum tau tiv thaiv cov ntsiab lus. Piv nrog cov tsoos steel txuas hniav, aluminium alloy txuas hniav tsis tas yuav tsum tau siv tshuaj tiv thaiv corrosion, zoo heev txo cov nqi tu mus sij hawm ntev thiab ua haujlwm.
Qhov zoo tshaj plaws ua ke ntawm plasticity thiab processability
Aluminium alloy cov ntaub ntawv yog ib qho yooj yim rau extrusion thiab tsim, thiab profiles nrog ntau yam complex cross-sections yuav raug tsim, uas muab ntau possibilities rau choj tsim. Cov neeg tsim qauv tuaj yeem tsim cov qauv choj zoo nkauj thiab siv tau raws li qhov xav tau kom ua tau raws li qhov xav tau ntawm ob lub nroog niaj hnub rau toj roob hauv pes thiab kev ua haujlwm. Tsis tas li ntawd, aluminium alloy welding thiab kev sib txuas thev naus laus zis kuj tseem txhim kho tas li, ua rau kev tsim kho ntawm aluminium alloy txuas hniav yooj yim dua thiab sai dua.
Mechanical zog thiab kev sib txuas tshuab ntawm aluminium alloys
Kev txiav txim siab ntawm cov khoom siv kho tshuab Txawm hais tias aluminium alloys muaj qhov qis dua elastic modulus, lawv lub zog tshwj xeeb (qhov piv ntawm lub zog rau qhov ntom ntom) piv rau, lossis txawm tias zoo dua, cov hlau muaj zog. Qhov no txhais tau hais tias cov qauv aluminium alloy tuaj yeem sib dua thaum nqa tib lub nra. Nyob rau tib lub sijhawm, cov yam ntxwv ntawm elastic deformation ntawm aluminium alloys yuav tsum tau muab coj los txiav txim siab thaum lub sijhawm tsim, thiab qhov nruj thiab lub zog ntawm cov qauv yuav tsum tsim kom muaj kev ruaj ntseg thiab ruaj khov ntawm cov qauv.
Innovation thiab Kev Txhim Kho ntawm Kev Sib Txuas Tshuab
Aluminium alloys tuaj yeem txuas nrog ntau txoj hauv kev, suav nrog kev sib txuas bolted, kev sib txuas rivet thiab kev sib txuas welded. Txhawm rau txo qis galvanic corrosion, aluminium rivets lossis bolts feem ntau yog siv hauv cov qauv txhuas alloy. Nyob rau tib lub sij hawm, nrog rau kev txhim kho ntawm vuam tshuab, vuam kev ua tau zoo ntawm aluminium alloys kuj tau zoo heev. MIG welding (melting inert gas welding) thiab TIG welding (tungsten inert gas welding) yog ob txoj kev siv txhuas alloy vuam uas tuaj yeem muab cov pob qij txha zoo welded uas ua tau raws li tus qauv siab ntawm kev tsim choj.
Kev ua haujlwm ruaj khov ntawm aluminium alloy txuas hniav
Tsim cov ntsiab lus rau kev ua haujlwm ruaj khov
Aluminium alloy Cheebtsam yuav raug kev txom nyem los ntawm lateral dabtsi yog khoov thiab torsional instability thaum raug khoov, uas yuav tsum tau tshwj xeeb saib xyuas thaum tsim. Txhawm rau txhim kho kev ruaj ntseg ntawm cov qauv, cov neeg tsim qauv tuaj yeem siv ntau yam kev ntsuas, xws li ntxiv cov kev txhawb nqa kab rov tav, hloov cov ntawv hla ntu, siv cov stiffeners, thiab lwm yam. Cov kev ntsuas no tuaj yeem txhim kho hauv zos thiab tag nrho kev ruaj ntseg ntawm aluminium alloy txuas hniav. thiab xyuas kom muaj kev ruaj ntseg ntawm cov qauv nyob rau hauv ntau yam loads.
Aluminium alloy choj piv txwv
Hangzhou Qingchun Road Middle River Pedestrian Choj
Tus choj no siv aluminium alloy truss qauv lub thawv girder, thiab cov khoom siv tseem ceeb yog 6082-T6 aluminium alloy. Tus choj 36.8-meter-ntev hnyav tsuas yog 11 tons, ua kom pom qhov zoo ntawm cov qauv tsim ntawm aluminium alloy txuas hniav. Tus qauv tsim ntawm tus choj tsis tsuas yog txiav txim siab ua haujlwm xwb, tab sis kuj suav nrog kev sib haum xeeb nrog ib puag ncig ib puag ncig, dhau los ua ib qho chaw zoo nkauj hauv nroog.
Shanghai Xujiahui Pedestrian Choj
Shanghai Xujiahui pedestrian choj tsim los ntawm Tongji University yog ua los ntawm 6061-T6 txhuas alloy, nrog ib tug ncua sij hawm ntawm 23 meters, ib tug dav ntawm 6 meters, ib tug tuag hnyav tsuas yog 150kN, thiab ib tug siab tshaj plaws load loj ntawm 50t. Kev tsim kho sai thiab muab tso rau hauv kev siv tus choj no qhia txog kev ua tau zoo thiab kev ua haujlwm ntawm aluminium alloy txuas hniav hauv cov nroog niaj hnub no.
Beishi Xidan Pedestrian Choj
Aluminium alloy superstructure ntawm Xidan Pedestrian Choj nyob rau hauv Bei City yog tsim los ntawm ib tug txawv teb chaws-nyiaj tuam txhab uas muag, thiab lub ntsiab aluminium alloy profile yog 6082-T6. Tag nrho qhov ntev ntawm lub ntsiab yog 38.1m, qhov dav dav ntawm tus choj lawj yog 8m, thiab tag nrho ntev yog 84m. Tus choj tau tsim nrog cov neeg taug kev kev nplij siab thiab kev nyab xeeb hauv siab. Nyob rau tib lub sijhawm, kev siv cov khoom siv aluminium alloy kuj tseem ua rau tus choj siv lub neej ntev dua thiab txo nqi txij nkawm.
Xaus
Daim ntawv thov ntawm high-end aluminium alloy cov ntaub ntawv nyob rau hauv choj kev tsim kho tsis tsuas yog txhim kho cov txheej txheem kev ua tau zoo thiab durability ntawm choj, tab sis kuj coj ntau possibilities rau choj tsim. Nrog rau kev nce qib ntawm cov ntaub ntawv tshawb fawb thiab kev tsim kho thev naus laus zis, aluminium alloy txuas hniav yuav tsum ua lub luag haujlwm tseem ceeb hauv kev tsim choj yav tom ntej thiab dhau los ua qhov tseem ceeb txuas txuas rau cov nroog niaj hnub.
