Ukufumana ukuqonda okubanzi ngakumbi kunye nokuvavanyai-aluminium ye-foamukusebenza.abaphandi baye bazisa iimpawu ezahlukeneyo zezalathi. Nangona kunjalo, ukuqonda kwangoku ukubaluleka kwezi zalathi ekuhlalutyeni ukusebenza kwe-aluminiyam yogwebu kulinganiselwe. Olu phononongo lusebenzisa i-Generalized Regression Neural Network (GRNN) indlela yokuseka imodeli edibanisa idatha ye-microstructure ye-aluminiyam ye-microstructure kunye neempawu zayo. Ngokusebenzisa i-CRNNmodel, abaphandi bakhupha ezine zezona zinto zibalulekileyo kunye nemilinganiselo yazo ehambelanayo yobunzima kwiimpawu ze-13 ze-pore ze-aluminium ye-foam. Emva koko, ifomyula entsha yokubonakalisa abalinganiswa, ebizwa ngokuba yi”Wang equivalent porosity”( WEP) , yaphuhliswa ngokusetyenziswa kobunzima obushiyekileyo obunikezelwe kubunzima beempawu, kwaye kwafunyanwa iparameters ezine coefficients. Le fomula ijolise ekuboniseni ubudlelwane phakathi kweempawu ze-aluminiyam ye-foam kunye nokusebenza kwayo ngoomatshini, Ngapha koko, abaphandi baqhube uqinisekiso lwemodeli besebenzisa idatha yoxinzelelo kwiiseti ezili-11 zealuminiyam yogwebu. Iziphumo zokuqinisekisa zibonise ukuba phakathi kwezi dathati ze-aluminiyam zili-11. Ifomula ye-Gibson-Ashby ivelise iziphumo ezididayo kwiimeko ezimbini, ngelixa i-WEP ibonise uzinzo olukhethekileyo ngaphandle kokuphazamiseka. Xa kuthelekiswa nefomula ye-Gibson-Ashby, i-WEP ibonise ukuchaneka kokuvavanya ukuphuculwa kwe-18.18%.

I-aluminium ye-foam, eyenziwe nge-aluminium metalor i-alloys yayo, ibonakaliswe ngobume bayo be-porous ezininzi ze-voids, kunye nesakhiwo esifana ne-honeycomb. Ukuphuhliswa kweendlela zovavanyo oluchanekileyo nolubanzi lufuneka ngokukhawuleza ukomeleza ukusetyenziswa kwe-aluminiyam yogwebu.

I Gibson - Ashby formulal kunye ne Hanssen formulat , yaziswa ngu Gibson kunye ne Ashby , ibambe ukubaluleka njengeequation zesintu zokuchaza iimpawu zoomatshini imathiriyeli ye porous Nangona kunjalo ,aluminiyam yogwebuibonisa i-microstructures ezahlukeneyo kwaye ichatshazelwa zizinto ezahlukeneyo zesakhiwo, ezifana ne-porosity, ubungakanani bepore, kunye nokuhanjiswa kwepore. Uninzi lolu lwalamano luqhelekileyo luyimifuziselo ye-macroscopic phenomenological engaphenduliyo ngempembelelo yezakhiwo zepore. Ngaphezu koko, i-aluminium ye-foam ingaba neemfuneko zokusebenza ezahlukeneyo kwiimeko ezahlukeneyo zesicelo. Ukongeza, intsimi ye-aluminium yogwebu ayinazo iindlela zokuvavanya ezisemgangathweni kunye neeparamitha zokusebenza, okukhokelela kumceli mngeni kunye nokuqinisekisa iziphumo kulo lonke uthelekiso. Isishwankathelo, iindlela zemveli ziyasilela ekusekeni ulungelelwaniso phakathi kweempawu ze-microstructural ze-aluminium yogwebu kunye neempawu zayo zomatshini okanye ukwenza imodeli echanekileyo kunye noqikelelo lweempawu zoomatshini be-aluminium yogwebu ngaphakathi kwendawo yeparameter. Ukuxhomekeka kuphela kwimbono ye-macroscopic yokuvavanya iipropathi zomatshini we-aluminiyam yogwebu ayisahlangabezani neemfuno zoyilo lwangoku. Ukusekwa kobudlelwane bemephu phakathii-aluminium ye-foamiiparamitha zesakhiwo kunye neempawu zayo zomatshini ngumba ocinezelayo kunye nobalulekileyo.

Kolu phononongo, iparamitha yokulinganisa inoveli ebizwa ngokuba yi-porosity elinganayo yacetywa ukuba imele ubudlelwane phakathi kweempawu ze-microstructural kunye nokusebenza kwe-aluminium yogwebu. Le parameter ithathwe kwi-weighted distribution of features ezifana ne-porosity, i-avareji yobungakanani bepore, kunye nesetyhula ye-aluminium ye-foam.Ngokuqinisekiswa kovavanyo kwiisampuli ze-aluminium ze-foam, kubonakaliswe ukuba i-porosity elinganayo, njengeparameter entsha yokulinganisa, inika ichaneke ngakumbi. imbonakalo yokusebenza kwe-aluminiyam yogwebu.

Kolu phononongo, samkela indlela yokwahluka ngokweendlela zokufundisa ngokudibanisa izinto zenzululwazi kunye nokufunda koomatshini. Ubuchule bokufunda ngomatshini, njengokukhethwa kweempawu, uhlalutyo lobunzima, kunye nolwabiwo lobunzima obushiyekileyo, zidityanisiwe ukuseka i-aformula ye-porosity elinganayo. Siye sabonisa ukuchaneka kwe-porosity elinganayo njengeparamitha entsha yokulinganisa ngokuqinisekisa iiseti zesampulu ezintlanu, ngokubonelela ngokuchanekileyo kokusebenza kwe-aluminium ye-foam. Sinikezela ngendlela echaneke ngakumbi yokuvavanya kunye nokuhlalutya iimpawu zoomatshini bemathiriyeli, inikezela ngezalathisi ezixabisekileyo zokwenziwa kwezigqibo kunye nohlalutyo. Uphando lungqamana ngokusondeleyo nokuhambela phambili okukhawulezayo kwedatha enkulu kunye netekhnoloji yobukrelekrele bokwenziwa ngokudibanisa uphando lwezixhobo eziqhutywa yidatha kunye nophononongo lwe-aluminiyam yogwebu. Sazisa iipateni zenoveli kunye neendlela, sinika umbono omtsha wophawu kunye nohlalutyo lwentsebenzo ye-aluminium yogwebu.
