Txoj kev tshawb fawb ntawm cov kws tshawb fawb ntawm Perm Polytetechnic yuav pab txhawb kev ua kom ntev ntawm choj. Lawv tau kawm li cas cov ntaub ntawv los ntawm cov khaubncaws sab nraud povtseg ntawm cov khaubncaws sab nraud povtseg ntawm lawv cov khoom siv tsim lawv tus kheej ntawm kev nqis tes ua ntawm cov chaw sab nraud. Qhov no yuav zam kev vau ntawm choj thiab txo cov nqi thiab ib ntus rau lawv kho.
Cov kws tshawb fawb tau ua haujlwm tiav nrog kev txhawb nqa nyiaj txiag ntawm Lavxias teb sab laj kev tshawb fawb. Cov txiaj ntsig ntawm kev ua haujlwm tau luam tawm hauv iOP lub rooj sib tham thiab engineering, kev hloov kho phau ntawv ntse thiab kev tshawb fawb hauv kev tshawb fawb hauv Digital.
"Tus naj npawb ntawm cov tsheb thiab kev tsheb ciav hlau thauj txhua xyoo nce, thiab cov kev xav tau rau lub luag haujlwm ntawm cov choj kuj nce ntxiv. Cov ntu siv tau ntsib kev thauj mus los tsis tu ncua los ntawm kev ua txhaum ntawm thermal thiab compression, shrinkage thiab seismic porturbations.
Txhawm rau txuas lub neej ntawm cov choj, cov khoom tiv thaiv niaj hnub niaj hnub cov ntaub ntawv thiab cov khoom sib xyaw yog siv ua txheej rau lawv cov khoom siv. Tab sis cov ntaub ntawv ntawm lawv cov khoom siv cov khoom siv thiab cov qauv ntawm "kev sib tw ua lej, siv cov me nyuam yaus thiab cov kws tshaj lij ntawm Biomechas" Perm Politeha Anna Kamensky.
Cov kws tshawb fawb tshawb xyuas qhov "kev coj cwj pwm" hauv cov txuas ntxiv ntawm cov choj ntawm ntau dua 30 kev cog lus polymer thiab cov khoom siv sib xyaw. Hauv tshwj xeeb, lawv kawm ultraigh molecular hnyav polyethylene, hloov pauv roogroplast thiab composites raws lawv. Siv cov qauv suav zauv ntawm cov kheej kev txhawb nqa ib feem ntawm tus choj, cov kws tshawb nrhiav pom tias cov ntaub ntawv txheej thiab cov khoom siv cuam tshuam rau kev ua kom muaj kev puas tsuaj thiab kev puas tsuaj.
Lawv muab piv rau cov seem uas txhawb nqa nrog txheej nrog ib tuab ntawm 4 mus rau 8 millimeters. Cov kws tshawb fawb tau pom tias qhov nce hauv txheej txheej me me kom txo cov txheej txheem deformation ntawm cov qauv fluoroplastic thiab siab molecular hnyav polyethylene.
Cov kws tshawb nrhiav tau kawm cov ntu ntawm kev txhawb nqa ntawm cov choj ntawm kev tsim cov permatekh, uas tau xav ua qhov project. Cov txiaj ntsig ntawm kev ua haujlwm ntawm cov kws tshawb fawb ntawm Permcisc Polytechnic twb tau siv nyob rau hauv kev tsim cov ntsiab lus tshiab ntawm Choj Cov Qauv Tshiab. Cov txiaj ntsig ntawm cov lej kev sim thiab cov kev sim sab hauv thiab kev suav engineering tau pab txhim kho cov qauv ntawm cov choj.
"Qauv ntawm kev coj ntawm cov ntaub ntawv nyob rau hauv qhov kev txiav txim ntawm ib puag ncig sab nraud yog cog lus rau siv tsis tsuas yog nyob rau hauv kev tsim kho, tabsis kuj nyob rau hauv lub tshuab, huab cua thiab kev lag luam tsheb. Ib qho ntxiv, lawv tuaj yeem siv Biomechanics thiab tshuaj - piv txwv li, thaum ua qauv "ntawm lub duav pob qij txha lossis endoprosthesis ntawm lub ntsag," piav qhia Anna Kamensky.
