Abacwaningi abavela eNyuvesi yaseColorado eBoulder kanye naseSandia National Laboratory e-United States baqalise uhlelo lokuguqula izintoizinto ezimunca ukushaqeka, okuyintuthuko ephumelelayo engashintsha ukuphepha kwemikhiqizo kusukela emishinini yezemidlalo kuya kwezokuthutha.
Le nto esanda kwakhiwa ebamba ukushaqeka ingamelana nemiphumela emibi kakhulu futhi ingafakwa maduze emishinini yebhola, ezigqokweni zamabhayisikili, futhi isetshenziswe ngisho nasekupakisheni ukuvikela izinto ezibucayi ngesikhathi sokuthuthwa.
Cabanga ukuthi le nto ebamba ukushaqeka ayikwazi nje ukuvikela umthelela, kodwa futhi ikwazi ukumunca amandla amaningi ngokushintsha isimo sayo, ngaleyo ndlela idlale indima ehlakaniphile kakhulu.
Yilokhu kanye okufezwe yileli thimba. Ucwaningo lwabo lushicilelwe ephephabhukwini lezemfundo i-Advanced Material Technology ngokuningiliziwe, luhlola ukuthi singadlula kanjani ukusebenza kweizinto ze-foam zendabukoIzinto ze-foam zendabuko zisebenza kahle ngaphambi kokuba zicindezelwe kakhulu.
Igwebu likhona yonke indawo. Likhona ezikhushini esiziphumulele kuzo, ezigqokweni esizigqokayo, kanye nasezingxotsheni eziqinisekisa ukuphepha kwemikhiqizo yethu yokuthenga online. Kodwa-ke, igwebu nalo linemikhawulo yalo. Uma licindezelwa kakhulu, ngeke lisaba thambile futhi linwebeke, futhi ukusebenza kwalo kokumuncwa komthelela kuzokwehla kancane kancane.
Abacwaningi abavela eNyuvesi yaseColorado eBoulder kanye naseSandia National Laboratory benze ucwaningo olujulile ngesakhiwo sezinto ezibamba ukushaqeka, besebenzisa ama-algorithms ekhompyutha ukuphakamisa umklamo ongahlobene nje kuphela nezinto ngokwazo, kodwa futhi nokuhlelwa kwezinto. Le nto yokudambisa ingamunca amandla angaphezu kwayisithupha kune-foam ejwayelekile kanye namandla angaphezu kwama-25% kunezinye ubuchwepheshe ezihamba phambili.
Imfihlo isesimeni sejometri sezinto ezibamba ukushaqeka. Umgomo osebenzayo wezinto ezivamile zokudambisa ukucindezela zonke izikhala ezincane ku-foam ndawonye ukuze kutholakale amandla. Abacwaningi basebenzisei-thermoplastic polyurethane elastomerizinto zokunyathelisa ze-3D ukudala isakhiwo se-lattice esifana ne-honeycomb esiwa ngendlela elawulwayo lapho sihlaselwa, ngaleyo ndlela simunce amandla ngempumelelo enkulu. Kodwa iqembu lifuna okuthile okubanzi kakhulu okungaphatha izinhlobo ezahlukene zemithelela ngokusebenza kahle okufanayo.
Ukuze bafeze lokhu, baqale ngomklamo we-honeycomb, kodwa base benezela ukulungiswa okukhethekile - ukushintshashintsha okuncane njengebhokisi le-accordion. Lawa ma-kink ahlose ukulawula indlela isakhiwo se-honeycomb esiwa ngayo ngaphansi kwamandla, okwenza sikwazi ukumunca kahle ukudlidliza okubangelwa yimithelela ehlukahlukene, kungakhathaliseki ukuthi kuyashesha futhi kuqinile noma kuhamba kancane futhi kuthambile.
Lokhu akukhona nje okungokombono. Ithimba locwaningo lihlole umklamo walo elabhorethri futhi lacindezela izinto zalo ezintsha ezibamba ukushaqeka ngaphansi kwemishini enamandla ukuze lifakazele ukusebenza kwalo. Okubaluleke kakhulu, le nto yokubeka izinto zobuchwepheshe obuphezulu ingakhiqizwa kusetshenziswa amaphrinta e-3D ezentengiselwano, okwenza ifaneleke ezinhlelweni eziningi ezahlukene.
Umthelela wokuzalwa kwale nto ebamba ukushaqeka mkhulu kakhulu. Kwabasubathi, lokhu kusho imishini ephephile enganciphisa ingozi yokushayisana nokuwa. Kubantu abavamile, lokhu kusho ukuthi izigqoko zamabhayisikili zinganikeza isivikelo esingcono ezingozini. Emhlabeni jikelele, lobu buchwepheshe bungathuthukisa konke kusukela ezithiyweni zokuphepha emigwaqweni emikhulu kuya ezindleleni zokupakisha esizisebenzisayo ukuthutha izimpahla ezibuthakathaka.
