Musi wa26 Chikumi, chitima chepasi pevhu che "CETROVO 1.0 Carbon Star Express" chakagadzirwa neCRRC Sifang Co., Ltd neQingdao Metro Group cheQingdao Subway Line 1 chakaburitswa zviri pamutemo muQingdao, inova ndiyo chitima chekutanga pasi pevhu che "carbon fiber" chinoshandiswa pakutengeserana. Chitima ichi chepasi pevhu chakareruka ne11% pane mota dzekare dzemetro, chine mabhenefiti akakosha akadai sekureruka uye kushandisa simba rakawanda, zvichiita kuti chitima chepasi pevhu chiwane kuvandudzwa kwegirinhi.
Munyaya ye tekinoroji yekufambisa njanji, kuyerwa kwehuremu hwemotokari, kureva, kuderedza huremu hwemuviri zvakanyanya sezvinobvira pasi pepfungwa yekuona kuti mota dzinoshanda zvakanaka uye kuderedza kushandiswa kwesimba remagetsi, ndiyo tekinoroji huru yekuita kuti mota dzechitima dzisanyanya kusviba uye dzisanyanya kupiswa necarbon.
Mota dzepasi pevhu dzechinyakare dzinonyanya kushandiswasimbi, aruminiyamu alloy nezvimwe zvinhu zvesimbi,yakaganhurirwa nehunhu hwezvinhu, inotarisana nedambudziko rekuderedza huremu. Kabhoni fiber, nekuda kwekureruka kwayo, simba rayo guru, kudzivirira kuneta, kuramba ngura nezvimwe zvakanakira, inozivikanwa se "mambo wezvinhu zvitsva", simba rayo rinodarika kashanu kupfuura simbi, asi huremu hwayo huri pasi pe1/4 yesimbi, chinhu chakanaka kwazvo chemotokari dzechitima dzakareruka.
CRRC Sifang Co., Ltd, pamwe chete neQingdao Metro Group nedzimwe nzvimbo, vakabata matekinoroji akakosha akadai sekugadzirwa kwakabatana kwekabhoni faibhachimiro chikuru chinotakura mutoro, kugadzira uye kugadzira zvinobudirira uye zvisingadhuri, kuongorora nekugadzirisa kwakangwara, uye kugadzirisa zvine hungwaru matambudziko ekushandiswa kwemainjiniya, zvichiita kuti kushandiswa kwezvinhu zvakagadzirwa nekabhoni fiber pachimiro chikuru chinotakura mutoro chemotokari dzemetro dzekutengeserana kuve kekutanga pasi rose.
Muviri wechitima chepasi pevhu, furemu rebogie nezvimwe zvivako zvikuru zvekutakura zvinhu zvakagadzirwa nezvinhu zvakasanganiswa nekabhoni fiber, tichiona kuvandudzwa kutsva kwekushanda kwemotokari, neyakareruka uye isingashandise simba zvakanyanya, simba rakawanda, kusimba kwakasimba kwezvakatipoteredza, kuderedza mari yekushanda nekuchengetedza hupenyu hwese pamwe nezvimwe zvakanakira zvehunyanzvi.
Yakareruka uye Inoshanda Nesimba Rakawanda
Kuburikidza nekushandiswa kwezvinhu zvakasanganiswa nekabhoni fiber, mota iyi yadzikiswa zvakanyanya. Kana tichienzanisa nemotokari dzesimbi dzepasi pevhu, mota yepasi pevhu ine carbon fiber yakadzikiswa ne25%, mota yeBogie frame yakadzikiswa ne50%, mota yese yakadzikiswa ne11%, simba rinoshandiswa ne7%, chitima chimwe nechimwe chinogona kuderedza kuburitswa kwecarbon dioxide kwematani angangoita 130 pagore, zvakaenzana nemaeka zana nerimwe ekurima miti.
Simba Rakakwirira uye Hupenyu Hurefu hweMagadzirirwo
Chitima cheSubway chinotanga kushanda zvakanakazvinhu zvakasanganiswa nekabhoni fiber, zvichiita kuti muviri uve wakareruka ukuwo uchivandudza simba remuviri. Panguva imwe chete, zvichienzaniswa nekushandiswa kwezvinhu zvesimbi zvechinyakare, zvikamu zvefuremu yebogie yecarbon fiber zvine simba rekudzivirira kukanganiswa, zviri nani kuramba kuneta, zvichiwedzera hupenyu hwebasa rechivako.
Kusimba Kwakanyanya Kwezvakatipoteredza
Muviri wakareruka unogonesa chitima kuti chishande zvakanaka, izvo zvisingangogumiri pazvinodiwa zvekuderedza uremu hwe axle chete, asiwo zvinoderedza kupera kwemavhiri nematrack. Mota iyi inoshandisawo tekinoroji ye radial inoshanda, iyo inogona kudzora mavhiri emotokari kuti apfuure nepakona ichitevedza nzira ye radial, zvichideredza zvakanyanya kupera kwevhiri nerail uye ruzha.Madhisiki ebhureki eCarbon ceramic, idzo dzinoramba kupfekwa uye kupisa, dzinoshandiswa kuderedza huremu uku dzichisangana nezvinodiwa zvakanyanya zvekushanda kwemabhureki.
Mari Yekushandisa Nekuchengetedza Yekudzikisa Nguva Yehupenyu
Nekushandiswa kwezvinhu zvakareruka zvekabhoni faibhaUye matekinoroji matsva, kushomeka kwemavhiri nechitima kwezvitima zve metro zve carbon fiber kwakadzikira zvakanyanya, izvo zvinoderedza zvakanyanya kugadziriswa kwemotokari nenjanji. Panguva imwe chete, kuburikidza nekushandiswa kwetekinoroji yedhijitari mbiri, SmartCare intelligent operation and maintenance platform yezvitima zve carbon fiber yakaona kuzviongorora uye kuzviongorora kuchengetedzeka, hutano hwechimiro uye mashandiro emotokari yese, yakavandudza mashandiro ekushanda nekugadzirisa, uye yakaderedza mari yekushanda nekugadzirisa. Mari yekutarisira chitima chehupenyu hwese yadzikiswa ne22%.
Mundima yetekinoroji yecarbon fiber yemotokari dzechitima, CRRC Sifang Co., Ltd, ichishandisa simba rayo remaindasitiri, yakavaka chikuva chakazara cheR&D, kugadzira uye kusimbisa kuburikidza nemakore anopfuura gumi ekuunganidza R&D uye hunyanzvi hwekushandira pamwe hwe "indasitiri-yunivhesiti-tsvakiridzo-kushandiswa", ichigadzira seti yakazara yehunyanzvi hweinjiniya kubvakabhoni faibhadhizaini yezvivakwa uye R&D kusvika pakuumba nekugadzira, kutevedzera, kuyedza, kuvimbisa mhando, nezvimwewo, uye kupa mhinduro yekumira kamwe chete yehupenyu hwese hwemotokari. Ipa mhinduro yekumira kamwe chete yehupenyu hwese.
Parizvino,kabhoni faibhaChitima chepasi pevhu chapedza bvunzo yemhando yefekitori. Zvichienderana nehurongwa, chichaiswa mukuratidzira vafambi muQingdao Metro Line 1 mugore rino.
Parizvino, munyaya dzekutakura njanji dzemumaguta muChina, nzira yekuderedza kushandiswa kwesimba, kuderedza kuburitswa kwemhepo ine kabhoni, uye kugadzira njanji dzemumaguta dzinoshanda zvakanaka uye dzisina kabhoni yakawanda ndiyo inonyanya kukosheswa mukusimudzira indasitiri iyi. Izvi zvinoita kuti kudiwa kwetekinoroji yakareruka kuwedzere kudiwa kwemotokari dzechitima.
Kutanga kwebhizinesikabhoni faibhachitima chepasi pevhu, kukurudzira chimiro chikuru chekutakura mota dzepasi pevhu kubva pasimbi, aruminiyamu alloy nezvimwe zvinhu zvesimbi zvechinyakare kusvika kucarbon fiber itsva, kuputsa miganhu yekuderedza huremu hwechimiro chesimbi chechinyakare, kuti vawane kuvandudzwa kutsva kwetekinoroji yechitima chepasi pevhu cheChina, kuchasimudzira shanduko yechitima chemumaguta cheChina chegreen uye low-carbon transit, kubatsira indasitiri yechitima chemumaguta kuzadzisa "dual-carbon". Ichaita basa rakakosha mukusimudzira shanduko yegirini uye low-carbon yekutakura njanji dzemumaguta dzemuChina uye kubatsira indasitiri yechitima chemumaguta kuzadzisa chinangwa che "dual-carbon".
