Ofufuza apanga mtundu watsopano wa zinthu zoyamwitsa za TPU polyurethane

Ofufuza ochokera ku yunivesite ya Colorado Boulder ndi Sandia National Laboratory ku United States ayambitsa kafukufuku watsopanozinthu zogwira mantha, komwe ndi chitukuko chopambana chomwe chingasinthe chitetezo cha zinthu kuyambira zida zamasewera kupita ku zoyendera.

Zipangizo zatsopanozi zomwe zimayamwa kugunda kwa mtima zimatha kupirira kugunda kwakukulu ndipo posachedwa zitha kuikidwa mu zida za mpira, zipewa za njinga, komanso kugwiritsidwa ntchito poika zinthu zofewa panthawi yonyamula.

Tangoganizani kuti chinthu chogwira kugunda kwamphamvuchi sichingochepetsa kugunda kwa chinthucho, komanso chimayamwa mphamvu zambiri mwa kusintha mawonekedwe ake, motero chimagwira ntchito yanzeru kwambiri.

Izi ndi zomwe gululi lakwaniritsa. Kafukufuku wawo adasindikizidwa mwatsatanetsatane mu magazini ya maphunziro ya Advanced Material Technology, pofufuza momwe tingapambanire magwiridwe antchito azipangizo zachikhalidwe za thovuZipangizo za thovu lachikhalidwe zimagwira ntchito bwino zisanapanikizidwe mwamphamvu kwambiri.

Thovu lili paliponse. Limapezeka m'mapilo omwe timagona, zipewa zomwe timavala, ndi ma phukusi omwe amaonetsetsa kuti zinthu zathu zogulira pa intaneti ndi zotetezeka. Komabe, thovu lilinso ndi zolepheretsa zake. Ngati litakanidwa kwambiri, silidzakhalanso lofewa komanso lotanuka, ndipo mphamvu yake yoyamwa idzachepa pang'onopang'ono.

Ofufuza ochokera ku Yunivesite ya Colorado Boulder ndi Sandia National Laboratory adachita kafukufuku wozama pa kapangidwe ka zinthu zomwe zimayamwa kugunda kwa mtima, pogwiritsa ntchito ma algorithms apakompyuta kuti apereke lingaliro la kapangidwe komwe sikungogwirizana ndi zinthu zokha, komanso momwe zinthuzo zimakhalira. Zinthuzi zimatha kuyamwa mphamvu zochulukirapo nthawi zisanu ndi chimodzi kuposa thovu wamba komanso mphamvu zochulukirapo 25% kuposa ukadaulo wina wotchuka.

Chinsinsi chake chili mu mawonekedwe a zinthu zomwe zimayamwa kugunda kwa mtima. Mfundo yogwirira ntchito ya zinthu zachikhalidwe zonyowetsa mthunzi ndikuyika malo onse ang'onoang'ono mu thovu kuti lizitha kuyamwa mphamvu. Ofufuza adagwiritsa ntchitoelastomer ya polyurethane ya thermoplasticZipangizo zosindikizira za 3D kuti apange kapangidwe ka uchi ngati lattice komwe kamagwa molamulidwa kakakhudzidwa, motero kumayamwa mphamvu bwino. Koma gululi likufuna chinthu china chodziwika bwino chomwe chingathe kuthana ndi mitundu yosiyanasiyana ya kugunda mogwira mtima mofanana.

Kuti akwaniritse izi, anayamba ndi kapangidwe ka uchi, koma kenako anawonjezera kusintha kwapadera - kusintha pang'ono ngati bokosi la accordion. Ma kinks awa cholinga chake ndi kulamulira momwe kapangidwe ka uchi kamagwera pansi pa mphamvu, zomwe zimathandiza kuti zizitha kuyamwa bwino kugwedezeka komwe kumachitika chifukwa cha kugundana kosiyanasiyana, kaya ndi kofulumira komanso kolimba kapena pang'onopang'ono komanso kofewa.

Izi sizongoganizira chabe. Gulu lofufuza linayesa kapangidwe kawo mu labotale ndipo linayika zinthu zawo zatsopano zonyamula mantha pansi pa makina amphamvu kuti litsimikizire kuti zimagwira ntchito bwino. Chofunika kwambiri, zinthu zapamwambazi zitha kupangidwa pogwiritsa ntchito makina osindikizira a 3D, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana.

Zotsatira za kubadwa kwa zinthu zonyamula manthazi n’zambiri. Kwa othamanga, izi zikutanthauza zida zotetezeka zomwe zingachepetse chiopsezo cha kugundana ndi kugwa. Kwa anthu wamba, izi zikutanthauza kuti zipewa za njinga zitha kupereka chitetezo chabwino pa ngozi. Padziko lonse lapansi, ukadaulo uwu ukhoza kusintha chilichonse kuyambira zotchinga zachitetezo pamisewu yayikulu mpaka njira zopakira zomwe timagwiritsa ntchito ponyamula katundu wosalimba.
