Ofufuza apanga mtundu watsopano wa thermoplastic polyurethane elastomer (TPU) shock absorber material

Ofufuza ochokera ku yunivesite ya Colorado Boulder ndi Sandia National Laboratory apanga kusinthazinthu zowononga mantha, yomwe ndi chitukuko chapansi 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 popakira kuti ziteteze zinthu zosalimba panthawi yamayendedwe.

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

Izi ndi zomwe gululi lakwanitsa. Kafukufuku wawo adasindikizidwa mu nyuzipepala yamaphunziro ya Advanced Material Technology mwatsatanetsatane, ndikuwunika momwe tingadutse magwiridwe antchito a thovu lachikhalidwe. 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 achita kafukufuku wozama pa kapangidwe ka zinthu zomwe zimachititsa mantha ndipo anakonza mapangidwe omwe sali okhudzana ndi zinthu zomwezo, komanso makonzedwe ake pogwiritsa ntchito ma aligorivimu apakompyuta. 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 elastomer zinthuzosindikizira za 3D, kupanga chisa cha uchi ngati chopangidwa ndi lattice chomwe chimagwa mosasunthika chikakhudzidwa, potero chimatenga mphamvu. Koma gululi likufuna china chapadziko lonse lapansi, chotha kuthana ndi zovuta zosiyanasiyana ndikuchita bwino komweko.

Kuti akwaniritse izi, adayamba ndi mapangidwe a uchi, koma pambuyo pake adawonjezera kusintha kwapadera - mfundo zazing'ono monga ma accordion bellows. Ma mfundowa amapangidwa kuti aziwongolera momwe chisa cha uchi chimagwera mokakamiza, kuti chizitha kuyamwa bwino kugwedezeka kopangidwa ndi zinthu zosiyanasiyana, kaya mwachangu, molimba kapena pang'onopang'ono komanso mofewa.

Izi sizongopeka chabe. Gulu lofufuzalo linayesa kapangidwe kawo mu labotale, ndikufinya zida zawo zatsopano zodzidzimutsa pansi pamakina amphamvu kuti awonetse mphamvu zake. 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. M'dziko lotambasuka, ukadaulo uwu ukhoza kuwongolera chilichonse kuyambira zopinga zachitetezo chamsewu waukulu kupita kunjira zopakira zomwe timagwiritsa ntchito ponyamula katundu wosalimba.
