ʻO ka hoʻohana ʻana i ka alumini porous spherical ʻO ka alumini porous spherical he mea metala i loaʻa kahi nui, kahi nui o ka nui o ka pore a me kahi porosity i loko o ka matrix alumini. He ʻano hou ia o nā mea hana hoʻolālā pili i ke kaiapuni e hoʻohui i nā ʻano waiwai maikaʻi loa. E pili ana i ka aerospace, nā mea hana ordnance, ka mīkini hana, nā moku a me nā kaʻa ʻāina, ke kūkulu ʻana a me nā ʻoihana ʻē aʻe, ke koi nui ʻia ka noi no nā mea alumini porous spherical porous i ka hoʻoheheʻe ʻana i ke kani a me ka hoʻohaʻahaʻa ʻana i ka leo, ka hoʻoulu ʻana o ka ikehu a me ka buffering, ka hoʻohaʻahaʻa haʻalulu, ka pahū-hōʻoia, ka wela wela. , kānana, hoʻoheheʻe hawewe, pale pale uila a me nā noi ʻē aʻe.

Ka hoʻohana ʻana i ka alumini porous spherical i ka aerospace

1. Ka hana ʻana i nā mea koʻikoʻi i nā cushions ea

Ua hoʻomohala ʻia ka ʻūnaʻi lele lele pepa kila ma ka “Plane ʻElima Makahiki ʻumikūmālua o koʻu ʻāina” he kiʻekiʻe kiʻekiʻe a me ka hiki ke hoʻoheheʻe i ka ikehu liʻiliʻi. ʻO ka hoʻoulu ʻana o ka ikehu ma kahi o 500KJ/m3, a kūpono wale ia no nā lako mokulele o kahi 10 tons. Me ka hoʻokomo ʻana o 20 mau mokulele nui, pono ia e hāʻawi i nā cushions no nā mea koʻikoʻi o ka ea ma kahi o 20 tons. Hōʻike ʻia nā cushions airborne no nā mea koʻikoʻi i hana ʻia me ka alumini spherical foam ma ke Kiʻi 1, hiki ke hoʻohana ʻia i nā kaʻa pale kaua, nā pahu, a me nā mea ʻē aʻe. i ka ea lako lako o 20 tons, ka theoretical mānoanoa o ka pale anuu mea he 250mm, a me ka maoli mānoanoa i koho 'ia e like me 500-800mm, a me ka pae ana ua paʻa; hiki iā ia ke hoʻomaopopo i ka mokulele mokulele, ʻaʻole hiki ke hōʻoia i ka palekana o ke ola o nā koa, akā ma hope koke o ka pae ʻana. E komo i ke kaua a hoʻonui i ka hoʻouka kaua ʻana o kāu mau pūʻali mokulele.

2. Ka hana ʻana i nā uhi manhole me ka hoʻokuʻu ʻana i ka missile

Hana ʻia nā uhi silo missile e pili ana i ka ʻāina me ke kila kalapona a i ʻole ka iwi hao hao, ka mea i hoʻoikaika ʻia a me nā mea ʻē aʻe (Figure 2). ʻO ka uhi manhole nui ma kahi o 22 mika ka lōʻihi, ma kahi o 9 mau mika ākea, 1.5 mika ka mānoanoa, a ʻoi aku ke kaumaha ma mua o 600 tons. He nui loa ka uhi manhole, ʻaʻole kūpono i ka pane wikiwiki o ka wehe ʻana a me ka pani ʻana. ʻO ka uhi manhole nui me ka hoʻohana ʻana i ke ʻano hui o ka pā kila a me ka pahu alumini spherical i hōʻike ʻia ma ke kiʻi 3. ʻO ka ʻili luna he 20mm mānoanoa pā kila, ʻo ka mānoanoa spherical alumini pahu waena he 600mm; ʻO ka papa lalo he PE fiberboard 20mm, a ʻo ka papa kila o lalo he 10mm mānoanoa. ʻO ke kaumaha he 90 tons, a ua hoʻonui ʻia ka anti-knock ma mua o 1000 mau manawa. Ua hoʻohana ʻia ka GBU-28 semi-armor-piercing projectile me ke anawaena o 370mm a me ka pahū kiʻekiʻe o 306 kg e hoʻohālikelike. Ma muli o ka hopena hoʻopaʻa paʻa ʻana o ka alumini spherical spherical 600mm mānoanoa, ua hoʻonui ʻia ka wahi o ka projectile pale kaua ma ka pā kila kila 20mm-mānoanoa i ʻoi aku ma mua o 200 mau manawa. No laila, ʻo ke kuleana o ka projectile pale kaua Hoʻemi ʻia ka ikaika ma lalo o hoʻokahi haneli pakeneka, e paʻakikī ai ke komo.

3. Ke hana 'ana i ka puka pahū alumini spherical foam

ʻO ka puka pahū pahū i hoʻohana ʻia i kēia manawa (Figure 4) he 300-400mm ka mānoanoa, he 20-30 tons ke kaumaha, a me ka mana anti-explosion o 3Mpa. No ka mea kaumaha loa, paʻakikī ke wehe a pani. Hana ʻia ka puka pahū me ke kalapona kila / sphere foam aluminum composite structure (Figure 5). He 5mm ka mānoanoa o ka pā kila kalapona, a ʻo ka ʻāpana waena he 100mm mānoanoa spherical foam aluminika. Hoʻopili ʻia ka pā alumini spherical foam a me ka pā kila me ka silicone structural adhesive, a laila hoʻoikaika ʻia me nā bolts countersunk. ʻOi aku ka mana anti-knock ma mua o 1000Mpa, i hoʻonui ʻia e 300 mau manawa. ʻO ka ikaika compressive e like me ka ikaika o kahi pā kila paʻa me ka mānoanoa o 110mm; ʻo ka nuipaʻa he 1/12 o ka puka pahū pahū i hoʻoikaika ʻia. hoʻololi.
