Abacwaningi abavela eNyuvesi yaseColorado eBoulder naseSandia National Laboratory bathuthukise indlela entsha yokuguqula izintoizinto ezimunca ukushaqeka, okuyintuthuko entsha engashintsha ukuphepha kwemikhiqizo kusukela emishinini yezemidlalo kuya kwezokuthutha.
Le nto esanda kuklanywa ebamba ukushaqeka iyakwazi ukumelana nemiphumela emibi kakhulu futhi ingase ihlanganiswe maduze nemishini yebhola, izigqoko zamabhayisikili, futhi isetshenziswe ngisho nasekupakisheni ukuvikela izinto ezibucayi ngesikhathi sokuthuthwa.
Cabanga ukuthi le nto ebamba ukushaqeka ayikwazi nje ukuvikela imithelela, kodwa futhi ikwazi ukumunca amandla amaningi ngokushintsha isimo sayo, ngaleyo ndlela isebenze ngokuhlakanipha okukhulu.
Yilokhu kanye okufezwe yileli thimba. Ucwaningo lwabo lushicilelwe ephephabhukwini lezemfundo i-Advanced Material Technology ngokuningiliziwe, luhlola ukuthi singadlula kanjani ukusebenza kwezinto ze-foam zendabuko. Izinto 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 naseSandia National Laboratory benze ucwaningo olujulile ngesakhiwo sezinto ezibamba ukushaqeka futhi baphakamise umklamo ongahlobene nje kuphela nezinto ngokwazo, kodwa futhi nokuhleleka kwazo kusetshenziswa ama-algorithms ekhompyutha. Le nto yokudambisa ingamunca amandla angaphezu kwayisithupha kune-foam ejwayelekile kanye namandla angaphezu kuka-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 basebenziseizinto ze-thermoplastic polyurethane elastomerngokunyathelisa kwe-3D, okudala isakhiwo se-lattice esifana ne-honeycomb esiwa ngendlela elawulwayo lapho sithinteka, ngaleyo ndlela simunce amandla ngempumelelo enkulu. Kodwa iqembu lifuna into ebanzi kakhulu, ekwazi ukusingatha izinhlobo ezahlukene zemithelela ngokusebenza kahle okufanayo.
Ukuze bafeze lokhu, baqale ngomklamo we-honeycomb, kodwa kamuva banezela ukulungiswa okukhethekile - amafindo amancane njenge-accordion bellows. Lawa mafindo aklanyelwe ukulawula indlela isakhiwo se-honeycomb esiwa ngayo ngaphansi kwamandla, okuvumela ukuthi simunce kahle ukudlidliza okubangelwa yimithelela ehlukahlukene, kungaba okusheshayo nokunzima noma okuhamba kancane nokuthambile.
Lokhu akukhona nje okungokombono. Ithimba locwaningo lihlole umklamo walo elabhorethri, licindezela izinto zalo ezintsha ezibamba ukushaqeka ngaphansi kwemishini enamandla ukuze libonise ukusebenza kwalo. Okubaluleke kakhulu, le nto yokubeka izinto ngobuchwepheshe 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. Ezweni elibanzi, lobu buchwepheshe bungathuthukisa konke kusukela ezithiyweni zokuphepha emigwaqweni emikhulu kuya ezindleleni zokupakisha esizisebenzisayo ukuthutha izimpahla ezibuthakathaka.
