Yepamusoro-yekupedzisira aruminiyamu alloy zvinhu: sarudzo yekuchinja yekusuma bhiriji rekuvaka
2024-04-18 09:52:59
Nekukurumidza kusimukira kwesainzi uye tekinoroji uye nekukasira kwekugara kwemaguta, mabhiriji, sechikamu chakakosha chekufambisa kwemadhorobha, anogara achivandudza mukugadzira uye nzira dzekuvaka. Mabhiriji esimbi echinyakare anoshandiswa zvakanyanya nekuda kwesimba rawo rakakwirira uye mutengo wakaderera. Zvisinei, nekufamba kwenguva, matambudziko akadai sekuora uye mari yekuchengetedza zvakanyanya zvishoma nezvishoma. Tichipesana neizvi, yakakwirira-yekupedzisira aruminiyamu alloy zvinhu zvave sarudzo yekuchinja mumunda wekuvaka bhiriji nemabhenefiti avo akasiyana ekuita.
Zvakanakira zvealuminium alloy zvinhu
Zvakanakira lightweight design
Density yealuminium alloy inenge 2.7 g/cm³, inongove inenge 1/3 yesimbi. Ichi chivakwa chakareruka chinorevei pakugadzira bhiriji uye kuvaka? Chekutanga, zvimiro zvemabhiriji zvakareruka zvinogona kuderedza zvinodiwa zvenheyo, zvichibvumira mabhiriji makuru kuvakwa munzvimbo dzine hurombo hwe geological mamiriro. Chechipiri, zvimiro zvakareruka zvinogona zvakare kuderedza mari yekufambisa uye yekuisa, iyo inonyanya kukosha munzvimbo dziri kure kana nzvimbo dzisina mukana. Pamusoro pezvo, zvimiro zvakareruka zvinogonawo kubatsira kuvandudza kuita kwekudengenyeka kwenyika panguva yekudengenyeka kwenyika nekuti huremu huremu hunoderedza masimba asina simba pasi pekudengenyeka kwenyika.
Kukosha kwekudzivisa kuora
Aluminium alloy zvinhu zvinogona kuumba dense oxide firimu munzvimbo yechisikigo. Iyi oxide firimu inogona kunyatsovhara kupindira kwehunyoro uye okisijeni, nekudaro ichidzivirira zvinhu kubva mukuora. Izvi zvinonyanya kukosha pakuvaka mabhiriji, sezvo mabhiriji anowanzo kuratidzwa kune maelement uye anoda kumira nemamiriro ekunze. Kuenzaniswa nemabhiriji esimbi echinyakare, mabhiriji aruminiyamu alloy haadi kazhinji anti-corrosion kurapwa, achidzikisa zvakanyanya mutengo wenguva refu yekugadzirisa uye mutoro webasa.
Iyo yakakwana kusanganiswa kwepurasitiki uye processability
Aluminium alloy zvinhu zviri nyore kuburitsa uye kugadzira, uye maprofiles ane akasiyana-siyana akaoma muchinjiko-zvikamu anogona kugadzirwa, ayo anopa mamwe mikana yekugadzira bhiriji. Vagadziri vanogona kugadzira yakanaka uye inoshanda mabhiriji zvimiro sezvinodiwa kuti isangane nezvinodiwa zviviri zvemaguta emazuvano emamiriro uye kushanda. Pamusoro pezvo, aluminium alloy welding uye tekinoroji yekubatanidza inogara ichivandudza, zvichiita kuti kuvakwa kwealuminium alloy mabhiriji kuve nyore uye nekukurumidza.
Mechanical zvivakwa uye yekubatanidza tekinoroji yealuminium alloys
Kutarisisa kwakadzama kwezvinhu zvemakanika Kunyange zvazvo aruminiyamu alloys ane yakaderera elastic modulus, iwo chaiwo simba (reshiyo yesimba kune density) inofananidzwa, kana kunyange nani pane, yakakwirira-simba simbi. Izvi zvinoreva kuti aluminium alloy zvimiro zvinogona kureruka paunenge uchitakura mutoro wakafanana. Panguva imwecheteyo, iyo elastic deformation maitiro ealuminium alloys inofanirwa kutariswa panguva yekugadzira, uye kuoma uye kusimba kwechimiro kunofanirwa kugadzirwa zvine musoro kuti ive nechokwadi chekuchengetedza uye kugadzikana kwechimiro.
Innovation uye Kuvandudzwa kweConnectivity Technologies
Aluminium alloys anogona kubatanidzwa nenzira dzakasiyana-siyana, kusanganisira mabhaudhi ekubatanidza, rivet yekubatanidza uye welded. Kuti uderedze galvanic corrosion, aluminium rivets kana mabhoti anowanzoshandiswa mualuminium alloy structures. Panguva imwecheteyo, nekuvandudza tekinoroji yewelding, iyo welding performance yealuminium alloys yakagadziridzwawo zvakanyanya. MIG welding (kunyunguduka inert gas welding) uye TIG welding (tungsten inert gas welding) nzira mbiri dzinowanzoshandiswa nealuminium alloy welding dzinogona kupa majoini emhando yepamusoro-soro anosangana nepamusoro-soro yekuvaka mabhiriji.
Kushanda kwakagadzikana kwealuminium alloy mabhiriji
Dhizaini Mapoinzi eKushanda Kwakagadzikana
Aluminium alloy components anogona kutambura kubva kune lateral bending uye torsional kusagadzikana kana ichiiswa pakukotama, izvo zvinoda kunyatsotariswa panguva yekugadzira. Kuti uvandudze kugadzikana kwechigadziro, vagadziri vanogona kutora matanho akasiyana-siyana, akadai sekuwedzera zvitsigiro zvakadzika, kushandura chimiro chemuchinjikwa, kushandisa stiffeners, nezvimwewo. Aya matanho anogona kunyatsogadzirisa kugadzikana kwepanyika uye kwese kugadzikana kwealuminium alloy mabhiriji. uye chengetedza kuchengetedzwa kwechimiro pasi pemitoro yakasiyana-siyana.
Aluminium alloy bhiriji mienzaniso
Hangzhou Qingchun Road Middle River Pedestrian Bridge
Iri bhiriji rinoshandisa aluminium alloy truss chimiro bhokisi girder, uye chikuru bhiriji zvinhu 6082-T6 aruminiyamu alloy. Iyo 36.8-mita-yakareba zambuko rinorema matani gumi nerimwe chete, zvichiratidza zvakanakira dhizaini yakareruka yemabhiriji aruminiyamu alloy. Dhizaini yebhiriji haingotarise kushanda chete, asi zvakare inofunga zvizere kuwirirana nenzvimbo yakapoteredza, ichiva nzvimbo yakanaka muguta.
Shanghai Xujiahui Pedestrian Bridge
Bhiriji rekufamba netsoka reShanghai Xujiahui rakagadzirwa neTongji University rakagadzirwa ne6061-T6 aruminiyamu alloy, ine span imwe chete yemamita makumi maviri nenhatu, hupamhi hwemamita matanhatu, huremu hwakafa hwe150kN chete, uye huremu hwepamusoro hwe50t. Kukurumidza kuvakwa uye kuiswa mukushandiswa kwebhiriji iri kunoratidza kushanda uye kugona kwemabhiriji ealuminium alloy mumaguta anhasi.
Beishi Xidan Pedestrian Bridge
Iyo aruminiyamu alloy superstructure ye Xidan Pedestrian Bridge muBei City yakavakwa nekambani inobhadhara mari kune kunze kwenyika, uye iyo huru yealuminium alloy profile ndeye 6082-T6. Hurefu hwakazara hwehupamhi hunosvika 38.1m, hupamhi hwakajeka hwebhiriji dhizaini 8m, uye hurefu hwakazara 84m. Zambuko racho rakagadzirwa zvine kugadzikana kwevanofamba netsoka uye kuchengeteka mupfungwa. Panguva imwecheteyo, kushandiswa kwealuminium alloy zvinhu kunopawo bhiriji hupenyu hurefu hwebasa uye kuderera kwekugadzirisa mari.
Mhedziso
Iko kushandiswa kwepamusoro-yekupedzisira aluminium alloy zvinhu mukuvaka bhiriji hakungogadzirisi kuita kwemaitiro uye kusimba kwemabhiriji, asi zvakare kunounza mimwe mikana yekugadzira mabhiriji. Nekufambira mberi kwesainzi yezvinhu uye kuvandudzwa kwehunyanzvi hwekuvaka, mabhiriji ealuminium alloy anotarisirwa kuita basa rakakosha mukuvaka mabhiriji mune ramangwana uye kuve chinhu chakakosha chinobatanidza maguta emazuva ano.
