Abaphandi abavela kwiYunivesithi yaseColorado Boulder kunye neSandia National Laboratory baye baphuhlisa inguquizinto ezothusayo, oluluphuhliso olusisiseko olunokutshintsha ukhuseleko lweemveliso ezivela kwizixhobo zemidlalo ukuya kwezothutho.
Esi sixhobo sisandul' ukuyilwa esothusayo siyakwazi ukumelana neempembelelo ezibalulekileyo kwaye kungekudala sinokudityaniswa nezixhobo zebhola ekhatywayo, izigcina-ntloko zebhayisekile, kwaye zide zisetyenziswe ekupakisheni ukukhusela izinto ezibuthathaka ngexesha lokuhamba.
Khawufane ucinge ukuba le mathiriyeli ifunxa umothuko ayinakuchaphazela kuphela iimpembelelo, kodwa ikwafunxa amandla angakumbi ngokuguqula imilo yayo, ngaloo ndlela isebenze ngobukrelekrele.
Yile nto kanye ethe yaphunyezwa leli qela. Uphando lwabo lwapapashwa kwijenali yezifundo ye-Advanced Material Technology ngokweenkcukacha, bephonononga ukuba sinokodlula njani ukusebenza kwezixhobo zogwebu zemveli. Izixhobo zogwebu zemveli zisebenza kakuhle phambi kokuba zicudiswe kakhulu.
Ugwebu lukho kuyo yonke indawo. Ikhona kwiikhushini esiphumla kuzo, izigcina-ntloko esizinxibayo, kunye nokupakishwa okuqinisekisa ukhuseleko lweemveliso zethu zokuthenga kwi-intanethi. Nangona kunjalo, i-foam nayo inemida yayo. Ukuba icudiswe kakhulu, ayisayi kuphinda ithambile kwaye i-elastic, kwaye ukusebenza kwayo kwefuthe kuya kuhla kancinci.
Abaphandi abavela kwiYunivesithi yaseColorado Boulder kunye neSandia National Laboratory baye baqhuba uphando olunzulu malunga nesakhiwo sezinto ezothusayo kwaye bacebise uyilo olungahambelani kuphela nezinto ngokwazo, kodwa kunye nolungiselelo lwayo usebenzisa i-algorithms yekhompyutha. Esi sixhobo sifunxayo sinokufunxa amandla aphindwe kathandathu ngaphezu kogwebu oluqhelekileyo kunye ne-25% yamandla ngaphezulu kunobunye ubugcisa obuphambili.
Imfihlelo ilele kwimilo yejometri yezinto ezothusayo. Umgaqo osebenzayo wezinto zemveli zokudambisa kukukhama zonke izithuba ezincinci kugwebu kunye ukuze zifunxe amandla. Abaphandi basebenziseizinto thermoplastic polyurethane elastomerkushicilelo lwe-3D, ukwenza i-honeycomb efana ne-lattice structure edilikayo ngendlela elawulwayo xa ichaphazeleka, ngaloo ndlela ifunxa amandla ngokufanelekileyo. Kodwa iqela lifuna into engaphaya, ekwaziyo ukujongana neentlobo ezahlukeneyo zeempembelelo ngokusebenza okufanayo.
Ukufezekisa oku, baqala ngoyilo lwe-honeycomb, kodwa kamva bongeza uhlengahlengiso olukhethekileyo - amaqhina amancinci afana ne-accordion bellows. La maqhina enzelwe ukulawula indlela ubume benqatha lobusi oluwa phantsi kokunyanzeliswa, luvumela ukuba lufunxe ngokutyibilikayo ungcangcazelo oluveliswa ziimpembelelo ezahlukeneyo, nokuba ziyakhawuleza kwaye zilukhuni okanye zicotha kwaye zithambe.
Oku akuyothiyori kuphela. Iqela lophando livavanye uyilo lwalo elabhoratri, licinezela imathiriyeli entsha yokufunxa ukothuka phantsi koomatshini abanamandla ukubonisa ukusebenza kwayo. Okubaluleke kakhulu, le mathiriyeli yobugcisa obuphezulu inokuveliswa kusetyenziswa abashicileli be-3D yorhwebo, iyenze ilungele uluhlu olubanzi lwezicelo.
Impembelelo yokuzalwa kwesi sixhobo sothusayo sikhulu kakhulu. Kubadlali, oku kuthetha ukuba izixhobo ezinokuthi zikhuseleke ezinokunciphisa umngcipheko wokungqubana kunye nokulimala kokuwa. Kubantu abaqhelekileyo, oku kuthetha ukuba izigcina-ntloko zebhayisekile zinokubonelela ngokhuseleko olungcono kwiingozi. Kwihlabathi elibanzi, obu bugcisa bunokuphucula yonke into ukusuka kwizithintelo zokhuseleko koohola bendlela ukuya kwiindlela zokupakisha esizisebenzisayo ukuthutha iimpahla ezibuthathaka.
