Abacwaningi abavela eNyuvesi yaseColorado Boulder kanye neSandia National Laboratory baye bahlakulela izinguqukoizinto ezimunca ukushaqeka, okuyintuthuko eyisisekelo engashintsha ukuphepha kwemikhiqizo kusukela kumishini yezemidlalo kuya kwezokuthutha.
Le nto esanda kwakhiwa ebamba ukushaqeka iyakwazi ukumelana nemithelela ebalulekile futhi ingase ihlanganiswe maduze nezinto zokusebenza zebhola lezinyawo, izigqoko zokuvikela amabhayisikili, futhi zisetshenziselwe emaphaketheni ukuze kuvikelwe izinto ezithambile ngesikhathi sokuthutha.
Cabanga ukuthi le nto ebamba ukushaqeka ayikwazi nje ukuvikela imithelela, kodwa futhi idonsa amandla engeziwe ngokushintsha ukuma kwayo, ngaleyo ndlela yenze ngobuhlakani kakhulu.
Yilokhu kanye elikuzuzile leli qembu. Ucwaningo lwabo lwashicilelwa kujenali yezemfundo i-Advanced Material Technology ngokuningiliziwe, ihlola ukuthi singakudlula kanjani ukusebenza kwezinto ezivamile zegwebu. Izinto zendabuko zegwebu zisebenza kahle ngaphambi kokuba zikhanywe kakhulu.
Igwebu ligcwele yonke indawo. Itholakala kuma-cushions esiphumule kuwo, izigqoko zokuzivikela esizigqokayo, kanye namaphakheji aqinisekisa ukuphepha kwemikhiqizo yethu yokuthenga ku-inthanethi. Nokho, igwebu nalo linemikhawulo yalo. Uma isiminyaniswe kakhulu, ngeke isathambile futhi inwebeka, futhi ukusebenza kwayo komthelela kuzokwehla kancane kancane.
Abacwaningi abavela eNyuvesi yaseColorado Boulder kanye neSandia National Laboratory benze ucwaningo olunzulu ngesakhiwo sezinto ezibamba ukushaqeka futhi bahlongoza umklamo ongahlobene nje kuphela nezinto ngokwazo, kodwa futhi nokuhlelwa kwawo kusetshenziswa ama-algorithms wekhompyutha. Lesi sici esimanzi singamunca amandla aphindwe kasithupha kunegwebu elijwayelekile kanye namandla angama-25% ngaphezu kobunye ubuchwepheshe obuphambili.
Imfihlo ilele esimweni sejometri yezinto ezibamba ukushaqeka. Umgomo wokusebenza wezinto ezijwayelekile zokuswakama ukukhama zonke izikhala ezincane zegwebu ukuze zimunce amandla. Abacwaningi basebenzisaI-thermoplastic polyurethane elastomer impahlaukuphrinta kwe-3D, ukudala ikhekheba lezinyosi njengesakhiwo se-lattice esiwa ngendlela elawulwayo uma ithintekile, ngaleyo ndlela imunca amandla ngempumelelo. Kodwa iqembu lifuna okuthile okukhona emhlabeni wonke, okukwazi ukuphatha izinhlobo ezahlukene zemithelela ngendlela efanele.
Ukuze kuzuzwe lokhu, baqala ngomklamo wekhekheba lezinyosi, kodwa kamuva bangeza izinguquko ezikhethekile - amafindo amancane afana ne-accordion bellows. Lawa mafindo aklanyelwe ukulawula ukuthi isakhiwo sekhekheba lezinyosi sibhidlika kanjani ngaphansi kokuphoqelelwa, ukusivumela ukuthi sibambe kahle ukudlidliza okukhiqizwa imithelela eyahlukahlukene, noma ngabe iyashesha futhi iqinile noma ihamba kancane futhi ithambile.
Lokhu akuyona nje ithiyori. Ithimba labacwaningi lihlole idizayini yabo elabhorethri, lacindezela izinto zabo ezintsha ezimunca ukushaqeka ngaphansi kwemishini enamandla ukubonisa ukusebenza kwayo. Okubaluleke kakhulu, le nto yobuchwepheshe obuphezulu bokucushwa ingakhiqizwa kusetshenziswa amaphrinta we-3D wezohwebo, iyenze ifaneleke uhla olubanzi lwezinhlelo zokusebenza.
Umthelela wokuzalwa kwalokhu okubamba ukushaqeka mkhulu kakhulu. Kubasubathi, lokhu kusho okokusebenza okungenzeka kuphephe okunganciphisa ingozi yokushayisana nokulimala kokuwa. Kubantu abavamile, lokhu kusho ukuthi izigqoko zamabhayisikili zinganikeza ukuvikeleka okungcono ezingozini. Emhlabeni obanzi, lobu buchwepheshe bungathuthukisa yonke into kusukela kuzithiyo zokuphepha emigwaqweni emikhulu kuya ezindleleni zokupakisha esizisebenzisayo ukuthutha izimpahla ezintekenteke.
