Ukusetyenziswa kwe-aluminium ene-spherical porous aluminium spherical porous aluminium yimathiriyeli yesinyithi equlethe isixa esithile, ubungakanani obuthile bobukhulu bepore kunye ne-porosity ethile kwi-aluminium matrix. Luhlobo olutsha lwezixhobo ezisebenzayo ezihambelana nokusingqongileyo ezidibanisa iintlobo ngeentlobo zeempawu ezigqwesileyo. Ukubandakanya i-aerospace, izixhobo ze-ordnance, ukwenziwa koomatshini, iinqanawa kunye nezithuthi zomhlaba, ulwakhiwo kunye namanye amashishini, imfuno yezinto ezingqukuva ze-aluminium ene-spherical igxininiswe ekufunjweni kwesandi kunye nokunciphisa ingxolo, ukufunxa amandla kunye nokuphazamisa, ukunciphisa ukungcangcazela, ubungqina bokudubula, ukutshatyalaliswa kobushushu. , ukuhluzwa, ukufunxwa kwamaza, ukukhuselwa kwe-Electromagnetic kunye nokunye izicelo.

Ukusetyenziswa kwe-aluminiyam engqukuva engqukuva kwi-aerospace

1. Ukwenza izixhobo ezikhulu iikhushini ezisemoyeni

Isitya sentsimbi esisemoyeni umqamelo wobusi ophuhliswe kwilizwe lam “kwiSicwangciso seMinyaka emiHlanu” yelizwe lam inoxinano oluphezulu kunye nomthamo omncinci wesithinteli sokufunxa amandla. Ukufunxa amandla malunga ne-500KJ/m3, kwaye ifanelekile kuphela kwizixhobo zomoya ezimalunga neetoni ezili-10. Ngokufakela iinqwelo-moya ezinkulu ezingama-20, kuyafuneka ukuba kubekho imiqamelo yezixhobo ezisebenza emoyeni ezimalunga neetoni ezingama-20. I-cushions emoyeni yezixhobo ezinzima ezenziwe nge-aluminium ye-foam e-spherical iboniswe kwi-Figure 1, engasetyenziselwa ukuhamba ngeenqwelo zomoya, iitanki, njl njl.; xa izixhobo zomoya weetoni ezingama-20, ubukhulu bethiyori yeqonga le-buffer yi-250mm, kwaye ubukhulu bokwenene bukhethwe njenge-500-800mm, kwaye ukuhla kuzinzile; Iyakwazi ukuqonda inqwelomoya ephathwayo, engaqinisekanga kuphela ukhuseleko lobomi bamajoni, kodwa nangoko emva kokufika. Ngena edabini kwaye wandise ukusebenza kakuhle kwemikhosi yakho yasemoyeni.

2. Ukwenza izigqubuthelo zomjukujelwa wokundululwa emhlabeni

Izigqubuthelo ze-silo ze-missile ezisekelwe kumhlaba zenziwe nge-carbon steel okanye i-alloy steel skeleton, ikhonkrithi eyomeleziweyo kunye nezinye izinto (Umfanekiso 2). Isigqubuthelo somngxuma omkhulu simalunga neemitha ezingama-22 ubude, malunga neemitha ezili-9 ububanzi, iimitha ezisisi-1.5 ubukhulu, kunye nobunzima obungaphezu kweetoni ezingama-600. Isigqubuthelo somngxuma sininzi kakhulu, esingahambelani nokuphendula ngokukhawuleza kokuvula nokuvala. Isigqubuthelo somngxuma omkhulu sisebenzisa ulwakhiwo oludityanisiweyo lwepleyiti yentsimbi kunye negwebu le-aluminiyam elingqukuva liboniswe kuMfanekiso 3. Umphezulu ophezulu yipleyiti yentsimbi eshinyeneyo engama-20mm, ubukhulu obuyingqukuva ye-aluminiyam ephakathi yi-600mm; umaleko osezantsi yi-PE fiberboard 20mm, kwaye ipleyiti yentsimbi esezantsi yi-10mm ubukhulu. Ubunzima buziitoni ezingama-90, kwaye i-anti-nknock yanda ngamaxesha angaphezu kwe-1000. I-GBU-28 i-semi-armor-piercing projectile enobubanzi be-370mm kunye ne-high-explosive charge ye-306 kg yayisetyenziselwa ukulinganisa. Ngenxa yempembelelo yoxinzelelo lwe-600mm-thick spherical foam aluminiyam, indawo yeprojectile yokugqobhoza isikrweqe kwipleyiti yentsimbi etyebileyo engama-20mm yandiswe ukuya ngaphezulu kwamaxesha angama-200. Ngoko ke, indima yeprojekthi yokubhoboza izixhobo Amandla ancitshiswa abe ngaphantsi kweepesenti ezilikhulu, okwenza kube nzima ukungena.

3. Ukwenza ucango olungqukuva lwealuminiyam olunogwebu olungagqabhuki

Ucango olusetyenziswayo ngoku oluqiniweyo oluqinileyo lwekhonkrithi olunokuthintela ugqabhuko-dubulo (Umfanekiso 4) unobunzima bubonke obuyi-300-400mm, ubunzima beetoni ezingama-20-30, kunye nomthamo wokuchasana nokudubula oyi-3Mpa. Ekubeni inzima kakhulu, kunzima ukuyivula nokuvala. Ucango-ubungqina bokuqhuma lwenziwe nge-carbon steel plate / sphere foam aluminiyam i-composite structure (Umfanekiso 5). Iphaneli yentsimbi ye-carbon yi-5mm ubukhulu, kwaye isandwich ephakathi yi-100mm engqindilili ye-aluminium ye-foam eyi-spherical. Ipleyiti ye-aluminiyam ye-foam engqukuva kunye nepleyiti yentsimbi incanyathiselwe nge-adhesive ye-silicone yesakhiwo, kwaye emva koko yomelezwa ngeebholiti ze-countersunk. Ubuchule bokuchasana nokunkqonkqoza bungaphezulu kwe-1000Mpa, eyonyuswe ngamaxesha angama-300. Amandla oxinzelelo alingana namandla eplate yensimbi eqinile kunye nobukhulu be-110mm; ubunzima yi 1/12 yolo locango oluqiniweyo oluqinileyo olungena kudubula. tshintsha.
