Maererano nehuwandu hweWorld Health Organization, makumi emamiriyoni evanhu pasi rose vanoda prosthetics. Huwandu uhu hunotarisirwa kupeta nekaviri panosvika 2050. Zvichienderana nenyika nezera, 70% yevanoda ma prostheses inosanganisira mitezo yepasi. Parizvino, emhando yepamusoro-fiber-reinforced composite prostheses haiwanikwe kune vakawanda vakadimburwa makumbo nemakumbo nekuda kwemutengo wakakura unosanganisirwa nemaitiro avo akaomarara, ekugadzira nemaoko. Mazhinji kabhoni fiber-reinforced polymer (CFRP) tsoka inogadzirwa nemaoko nekuisa akawanda akaturikidzanaprepregkuita muforoma, ipapo kurapa mutangi rinopisa rokutsikirira, richiteverwa nokuchekerera nokukuya, muitiro unodhura zvikuru wamanyorero.
Nekufambira mberi kwetekinoroji, kuunzwa kweotomatiki yekugadzira michina yemakompositi inotarisirwa kudzikisa mutengo zvakanyanya. Fiber winding tekinoroji, yakakosha musanganiswa wekugadzira maitiro, iri kushandura nzira yepamusoro-inoshanda composite prosthetics inogadzirwa, ichiita kuti ishande uye ine mari.
Chii chinonzi Fiber Wrap Technology?
Fiber winding (Fiber winding) inzira umo mafiber anoramba achiroverwa pafayiti inotenderera kana mandrel. Iyi fiber inogona kuvaprepregspre-impregnated withresinkana kupihwa pamuviri naresinpanguva yekutsvaira. Iyo fiber inokuvadzwa munzira dzakananga uye makona kuti asangane ne deformation uye simba mamiriro anodiwa nedhizaini. Pakupedzisira, chimiro cheronda chinorapwa kuti chigadzire chikamu chisina kuremerwa uye chepamusoro-simba.
Kushandiswa kweFiber Wrap Technology muProsthetic Manufacturing
(1) Kugadzirwa kwakanaka: Fiber winding tekinoroji inoona otomatiki uye kutonga kwakaringana, izvo zvinoita kuti kugadzirwa kweprosthesis kukurumidze. Kuenzaniswa nekugadzirwa kwechinyakare kwemanyorero, fibre winding inogona kuburitsa huwandu hukuru hwemhando yepamusoro prosthetic zvikamu munguva pfupi.
(2) Kudzikiswa kwemutengo: tekinoroji yeFiber winding inogona kudzikisa zvakanyanya mutengo wekugadzira weprostheses nekuda kwekuvandudzwa kwekuita kwekugadzira uye kushandiswa kwezvinhu. Zvinonzi kugamuchirwa kwehunyanzvi uhu kunogona kuderedza mutengo weprosthesis ne50%.
(3) Kuwedzera kwekuita: Fiber winding tekinoroji inogona kunyatso kudzora kurongeka uye kutungamira kwemafibhi kuti ikwidze ma mechanic properties yeprosthesis. Nhengo dzeProsthetic dzakagadzirwa nekabhoni fiber reinforced composites (CFRP) hadzisi kuremerwa chete, asiwo dzine simba rakanyanyisa uye kusimba.
(4) Sustainability: Maitiro ekugadzira anobudirira uye kushandiswa kwezvinhu kunoita kuti tekinoroji yefiber winding ive nehushamwari. Pamusoro pezvo, kusimba uye kusaremerwa kwechimiro cheanosanganiswa prostheses kunobatsira kuderedza kutambisa zviwanikwa uye kushandiswa kwesimba nemushandisi.
Nekuenderera mberi kwekufambira mberi kwefiber winding tekinoroji, kushandiswa kwayo mukugadzira prosthesis kuri kuvimbisa. Mune ramangwana, isu tinogona kutarisira kune akangwara ekugadzira masisitimu, akawanda akasiyana-siyana sarudzo dzezvinhu, uye mamwe emunhu prosthetic dhizaini. Fiber winding tekinoroji ichaenderera mberi nekusimudzira kusimudzira kweindasitiri yekugadzira prosthesis uye kuunza pundutso kumamirioni avanhu vanoda ma prostheses pasi rese.
Overseas Research Progress
Steptics, kambani inotungamira yekugadzira prosthetic, yakawedzera zvakanyanya kuwanikwa kweprosthetics kuburikidza neindasitiri yekugadzirwa kweCFRP prosthetics nekukwanisa kugadzira mazana ezvikamu pazuva. Kambani iyi inoshandisa tekinoroji yefiber winding kuti isango wedzera goho, asi zvakare kuderedza mitengo yekugadzira, ichiita kuti ma prosthetics epamusoro-soro agoneke kune vanhu vakawanda vanoshaya.
Maitiro ekugadzira Steptics 'carbon fiber composite prosthesis ndeaya anotevera:
(1) Huru yekuumba chubhu inotanga kugadzirwa uchishandisa faibha mhepo, sezvinoratidzwa pazasi, neToray's T700 kabhoni faibha inoshandiswa kuita fibre.
(2) Mushure mekunge chubhu yarapwa uye yaumbwa, tubing inochekwa kuita zvikamu zvakawanda (pazasi kuruboshwe), uyezve chikamu chimwe nechimwe chinochekwa nepakati (pazasi kurudyi) kuti uwane chikamu chakapedzwa.
(3) Mumashure mekugadzirisa, zvikamu zvakapedzwa zvinogadzirwa zvega, uye tekinoroji yeAI-yakabatsirwa inounzwa mukugadzirisa zvinhu zvakaita sejiometry uye kuoma kune munhu akadimburwa.
