Abaphandi abavela kwiYunivesithi yaseColorado Boulder kunye neSandia National Laboratory eUnited States baye basungula uguquko.izinto ezothusayo, oluluphuhliso oluyimpumelelo olunokutshintsha ukhuseleko lweemveliso ukusuka kwizixhobo zemidlalo ukuya kwezothutho.
Esi sixhobo sisandul' ukuyilwa sinokothuka sinokumelana neempembelelo ezinkulu kwaye kungekudala sinokudityaniswa nezixhobo zebhola ekhatywayo, izigcina-ntloko zebhayisekile, kwaye zide zisetyenziswe ekupakisheni ukukhusela izinto ezibuthathaka ngexesha lokuhamba.
Khawufane ucinge ukuba le mathiriyeli ibamba umothuko ayinako ukuthintela impembelelo kuphela, kodwa ikwafunxa amandla amaninzi ngokuguqula imilo yayo, ngaloo ndlela idlala indima ebukrelekrele.
Yile nto kanye ethe yaphunyezwa leli qela. Uphando lwabo lwapapashwa kwijenali yezifundo iAdvanced Material Technology ngokweenkcukacha, iphonononga ukuba singawugqwesa njani na umsebenziizinto amagwebu 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 baqhube uphando olunzulu malunga nesakhiwo sezinto ezothusayo, besebenzisa i-algorithms yekhompyutha ukucebisa uyilo olungahambelani nje kuphela nezinto ngokwazo, kodwa kunye nolungiselelo lwenkqubo. impahla. 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 basebenzisethermoplastic polyurethane elastomerimathiriyeli yoshicilelo lwe-3D ukwenza i-honeycomb efana ne-lattice structure edilikayo ngendlela elawulwayo xa iphantsi kwempembelelo, ngaloo ndlela ifunxa amandla ngokufanelekileyo. Kodwa iqela lifuna into engaphezulu yendawo yonke enokusingatha iintlobo ezahlukeneyo zeempembelelo ngokusebenza okufanayo.
Ukufezekisa oku, baqala ngoyilo lwe-honeycomb, kodwa emva koko bongeza uhlengahlengiso olukhethekileyo - ama-twist amancinci njengebhokisi ye-accordion. Ezi kinks zijolise ekulawuleni indlela i-honeycomb structure ewela ngayo phantsi kokunyanzeliswa, ivumela ukuba ikwazi ukufunxa kakuhle ukungcangcazela okwenziwa ziimpembelelo ezahlukeneyo, nokuba zikhawuleza kwaye zinzima okanye zicotha kwaye zithambile.
Oku akuyothiyori kuphela. Iqela lophando livavanye uyilo lwalo elabhoratri laza lacinezela imathiriyeli entsha efunxa umothuko 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.
