Ukuthuthukiswa kososayensi Perm Polytechnic kuzosiza ukugwema ukuwa kwamabhuloho

Ukutadisha kososayensi bePerm Polytechnic kuzosiza ukukhulisa ukuqina kwamabhuloho. Bafunda ukuthi izinto ezahlukene zezendlalelo zezinto zazo ziziveze kanjani ngaphansi kwesenzo sendawo yangaphandle. Lokhu kuzogwema ukuwa kwamabhuloho futhi kunciphise izindleko zezezimali nezesikhashana ukuze zilungiswe.

Ukuthuthukiswa kososayensi Perm Polytechnic kuzosiza ukugwema ukuwa kwamabhuloho

Ososayensi bagcwalise umsebenzi ngokuxhaswa kwezezimali kweSisekelo Sokucwaninga Okuyisisekelo saseRussia. Imiphumela yomsebenzi ishicilelwe ochungechungeni lwenkomfa ye-IOP: Isayensi Yezinto Zokwenziwa kanye nobunjiniyela, intuthuko yezinhlelo ezihlakaniphile kanye nochungechunge lwezincwadi lwezincwadi: Isayensi yedijithali kanye nesayensi ehlanganisiwe eminyaka yedijithali.

"Inani lezimoto nezitimela zokuhamba njalo ngonyaka liyanda, futhi izidingo zezinto ezinokwethenjelwa kwamabhuloho ziyanda. Izingxenye zezinkomba zibhekene nemithwalo engapheli evela ebhulohweni le-Bridge, zingaphansi kwesenzo sokwanda okushisayo kanye nokucindezelwa, ukuncipha kanye nokushaywa kwabantu abaningi.

Ukwelula impilo yamabhuloho, izinto zokwakha zanamuhla zokulwa nama-anticriction zisetshenziswa njengesendlalelo sezingxenye zabo zezinkomba. Kepha idatha esezakhiweni nasemotweni yazo emishini ye- "yokuziphatha" ayanele, "kusho ukhetho lwezesayensi yezobuchwepheshe, uprofesa wezobuchwepheshe womnyango" ama-macherating mathematics, ama-mechanics kanye ne-biomechanics "Pelm Politeha Anna Kamensky.

Ososayensi baphenya ngokuthi "ukuziphatha" ezingxenyeni ezisekelayo zamabhuloho aphezulu kwama-polymer angaphezu kwama-30 athembisayo nezinto ezihlanganisiwe. Ikakhulu, bafunda isisindo se-Ultrahigh Molecular Weight Polyethylene, iFloroPlast eguquliwe kanye nezinhlanganisela ezisuselwa kubo. Usebenzisa imodeli yezinombolo ephambene nengxenye yengxenye ye-spherical ukweseka kwebhuloho, abacwaningi bathola ukuthi ifomu elingezansi futhi izakhiwo zezinto zithinta kanjani ukonakala nokucekelwa phansi kwezinhlaka.

Baqhathanisa izingxenye ezisekelayo ngezendlalelo ezinobukhulu bezimilimitha ezi-4 kuya kwayi-8. Ososayensi bathole ukuthi ukwanda kobukhulu obufinyelela ku-6-8 millimers kunciphisa ukuguquguquka kwezinto ezakha izakhi, kanye nezinto zokwakha ezisebenza kahle kakhulu zokudala zibe yi-polyethylene ephezulu.

Abaphenyi bafunda izingxenye ezisekelayo zamabhuloho ngesisekelo sokukhiqizwa kwenkampani ye-Perm Alfatekh, eyaba nesithakazelo kulo msebenzi. Imiphumela yomsebenzi wososayensi we-Permcian Polytechnic isivele isetshenziswa ekwakhiweni kwezinto ezintsha zezakhiwo zebhuloho. Imiphumela yokuhlolwa kwezinombolo kanye ne-Entertional izibalo kanye nobunjiniyela basizwa ukuthuthukisa izakhiwo zamabhuloho.

"Amamodeli wokuziphatha kwezinto zokwenziwa ngaphansi kwesenzo sangaphandle athembisa ukusetshenziswa hhayi ekwakheni kuphela, kodwa futhi nasemikhakheni yezimoto. Ngaphezu kwalokho, zingasetshenziswa kuma-bioomechanics nomuthi - ngokwesibonelo, lapho kumodelwa "indlela yokuziphatha" yamalunga amadolo, "kuchaza u-Anna Kamengsky.
