Ofufuza apanga mtundu watsopano wa TPU polyurethane shock absorber material

Ofufuza ochokera ku yunivesite ya Colorado Boulder ndi Sandia National Laboratory ku United States akhazikitsa ndondomeko yosintha zinthu.zinthu zowononga mantha, yomwe ndi chitukuko chopambana chomwe chingasinthe chitetezo cha zinthu kuchokera ku zipangizo zamasewera kupita kumayendedwe.

Zinthu zomwe zangopangidwa kumenezi zimatha kupirira zovuta zambiri ndipo posachedwapa zitha kuphatikizidwa ndi zida za mpira, zipewa za njinga, ngakhalenso kugwiritsidwa ntchito m'mapaketi kuti ateteze zinthu zosalimba panthawi yamayendedwe.

Tangoganizani kuti chinthu chododometsa ichi sichingangowonjezera mphamvu, komanso chimatenga mphamvu zambiri posintha mawonekedwe ake, motero kuchita mbali yanzeru kwambiri.

Izi ndi zomwe gululi lakwanitsa. Kafukufuku wawo adasindikizidwa mu nyuzipepala yamaphunziro ya Advanced Material Technology mwatsatanetsatane, ndikuwunika momwe tingapambanire magwiridwe antchito azipangizo thovu chikhalidwe. Zipangizo zamtundu wa thovu zimagwira ntchito bwino musanafinyidwe molimba.

Chithovu chili paliponse. Imapezeka m'makhushoni omwe timapumira, zipewa zomwe timavala, ndi zopaka zomwe zimatsimikizira chitetezo cha zinthu zomwe timagula pa intaneti. Komabe, thovu limakhalanso ndi malire ake. Ngati ikafinyidwa kwambiri, sikhalanso yofewa komanso yotanuka, ndipo kuyamwa kwake kumachepa pang'onopang'ono.

Ofufuza ochokera ku yunivesite ya Colorado Boulder ndi Sandia National Laboratory anachita kafukufuku wozama pa kapangidwe ka zinthu zomwe zimachititsa mantha, pogwiritsa ntchito makina apakompyuta kuti apereke lingaliro la mapangidwe omwe sali okhudzana ndi zinthu zomwezo, komanso makonzedwe a zipangizo zomwe zimapangidwira. zakuthupi. Zinthu zonyowazi zimatha kuyamwa mphamvu kuwirikiza kasanu ndi kamodzi kuposa thovu wamba ndi mphamvu 25% kuposa matekinoloje ena otsogola.

Chinsinsi chagona mu mawonekedwe a geometric a zinthu zomwe zimasokoneza mantha. Mfundo yogwirira ntchito ya zida zonyowa zachikhalidwe ndikufinya tinthu ting'onoting'ono ta thovu kuti titenge mphamvu. Ofufuza ntchitoThermoplastic polyurethane elastomerzida zosindikizira za 3D kuti zipange chisa cha uchi ngati mawonekedwe a latisi omwe amagwa mowongolera akakhudzidwa, potero amamwa mphamvu. Koma gululi likufuna china chake chapadziko lonse lapansi chomwe chitha kuthana ndi zovuta zosiyanasiyana ndikuchita bwino komweko.

Kuti akwaniritse izi, adayamba ndi mapangidwe a uchi, koma adawonjezera kusintha kwapadera - zopindika zazing'ono ngati bokosi la accordion. Ma kink awa amafuna kuwongolera momwe chisa cha uchi chimagwera mokakamiza, kuti chizitha kuyamwa bwino kugwedezeka kopangidwa ndi zovuta zosiyanasiyana, kaya ndi zachangu komanso zolimba kapena zodekha komanso zofewa.

Izi sizongopeka chabe. Gulu lofufuzalo lidayesa kapangidwe kawo mu labotale ndikufinya zida zawo zatsopano zodzidzimutsa pansi pamakina amphamvu kuti atsimikizire kugwira ntchito kwake. Chofunika kwambiri, zida zapamwambazi zitha kupangidwa pogwiritsa ntchito makina osindikizira a 3D, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zosiyanasiyana.

Mphamvu ya kubadwa kwa zinthu zochititsa manthazi ndi zazikulu. Kwa othamanga, izi zikutanthauza zida zomwe zingakhale zotetezeka zomwe zingachepetse chiopsezo cha kugunda ndi kuvulala. Kwa anthu wamba, izi zikutanthauza kuti zipewa za njinga zimatha kupereka chitetezo chabwino pa ngozi. Padziko lonse lapansi, ukadaulo uwu ukhoza kusintha chilichonse kuyambira zotchinga zachitetezo m'misewu yayikulu mpaka njira zopakira zomwe timagwiritsa ntchito ponyamula katundu wosalimba.
