Abaphandi abavela kwiYunivesithi yaseColorado eBoulder kunye neSandia National Laboratory eMelika baqalise inguqulelo entshaizinto ezifunxa ukothuka, olu luphuhliso oluphambili olunokutshintsha ukhuseleko lweemveliso ukusuka kwizixhobo zemidlalo ukuya kwezothutho.
Le nto intsha eyilwe ngokuyila ukutsala uthuthu inokumelana neempembelelo ezinkulu kwaye kungekudala ingafakwa kwizixhobo zebhola ekhatywayo, izigcina-ntloko zebhayisekile, kwaye ingasetyenziswa nasekupakisheni ukukhusela izinto ezibuthathaka ngexesha lokuthuthwa.
Khawuthelekelele ukuba le nto ifunxa ukubetheka ayinakuyithintela nje kuphela impembelelo, kodwa ikwafunxa amandla angakumbi ngokutshintsha imo yayo, ngaloo ndlela idlala indima ekrelekrele ngakumbi.
Yile nto kanye eli qela eliyifezileyo. Uphando lwabo lupapashwe kwijenali yezemfundo i-Advanced Material Technology ngokweenkcukacha, behlola indlela esinokuyigqitha ngayo indlela esisebenza ngayoizixhobo zefoam zemveliIzinto zefoam zemveli zisebenza kakuhle ngaphambi kokuba zicinezelwe kakhulu.
Igwebu likho kuyo yonke indawo. Likho kwiikhushini esiphumla kuzo, kwiihelmethi esizinxibayo, nakwipakethe eqinisekisa ukhuseleko lweemveliso zethu zokuthenga kwi-intanethi. Nangona kunjalo, igwebu nalo linemida yalo. Ukuba licinezelwe kakhulu, alisayi kuba thambile kwaye lithambile, kwaye ukusebenza kwalo kokufunxa impembelelo kuya kwehla kancinci kancinci.
Abaphandi abavela kwiYunivesithi yaseColorado eBoulder nakwiSandia National Laboratory benze uphando olunzulu malunga nolwakhiwo lwezinto ezifunxa ukutsha, besebenzisa ii-algorithms zekhompyutha ukucebisa uyilo olungahambelani nje kuphela nezinto ngokwazo, kodwa nokulungelelaniswa kwezinto. Ezi zinto zokufunxa zinokufunxa amandla aphindwe kathandathu kune-foam eqhelekileyo kunye namandla angama-25% ngaphezu kwezinye iiteknoloji eziphambili.
Imfihlo ikwimo yejometri yezinto ezifunxa ukubetheka. Umgaqo osebenzayo wezinto zemveli zokufunxa ukufuma kukucinezela zonke iindawo ezincinci kwifoam kunye ukuze kufunxwe amandla. Abaphandi basebenzisei-thermoplastic polyurethane elastomerizixhobo zokuprinta ze-3D ukwenza isakhiwo se-honeycomb esifana ne-lattice esiwa ngendlela elawulwayo xa sichaphazeleka, ngaloo ndlela sifunxa amandla ngempumelelo. Kodwa iqela lifuna into ebanzi ngakumbi enokusingatha iintlobo ezahlukeneyo zeempembelelo ngendlela efanayo.
Ukuze bafezekise oku, baqale ngoyilo lwehoneycomb, kodwa emva koko bongeza uhlengahlengiso olukhethekileyo - ukujika okuncinci okufana nebhokisi ye-accordion. Ezi ngxaki zijolise ekulawuleni indlela isakhiwo sehoneycomb esiwa ngayo xa sisebenza, okusivumela ukuba sifumane kakuhle ukungcangcazela okubangelwa ziimpembelelo ezahlukeneyo, nokuba ziyakhawuleza kwaye ziqinile okanye ziyacotha kwaye zithambile.
Oku akupheleli nje kwingcamango. Iqela lophando livavanye uyilo lwabo kwilebhu kwaye lacinezela izinto zabo ezintsha ezitsala uloyiko phantsi koomatshini abanamandla ukuze kuqinisekiswe ukuba ziyasebenza. Okubaluleke ngakumbi, ezi zinto zikumgangatho ophezulu zokukhusela zinokuveliswa kusetyenziswa iiprinta ze-3D zorhwebo, nto leyo eyenza ukuba zifaneleke kwiintlobo ngeentlobo zezicelo.
Impembelelo yokuzalwa kwale nto ifunxa ukukhwankqiswa inkulu kakhulu. Kubadlali bezemidlalo, oku kuthetha izixhobo ezikhuselekileyo ezinokunciphisa umngcipheko wokungqubana kunye nokwenzakala kokuwa. Kubantu abaqhelekileyo, oku kuthetha ukuba izigcina-ntloko zebhayisekile zinokubonelela ngokhuseleko olungcono kwiingozi. Kwihlabathi liphela, obu buchwephesha bunokuphucula yonke into ukusuka kwimiqobo yokhuseleko kwiindlela ezinkulu ukuya kwiindlela zokupakisha esizisebenzisayo ukuthutha iimpahla ezibuthathaka.
