Ngomhlaka-26 Juni, isitimela sesitimela esingaphansi komhlaba i-“CETROVO 1.0 Carbon Star Express” esakhiwe yi-CRRC Sifang Co., Ltd kanye ne-Qingdao Metro Group se-Qingdao Subway Line 1 sakhishwa ngokusemthethweni e-Qingdao, okuyisitimela sokuqala emhlabeni esingaphansi komhlaba i-carbon fiber esisetshenziselwa ukusebenza kwezentengiselwano. Lesi sitimela sesitimela silula ngo-11% kunezimoto zesitimela zendabuko, sinezinzuzo ezibalulekile ezifana nokukhanya nokusebenza kahle kwamandla, okuholela isitimela sesitimela ukuthi sithole ukuthuthukiswa okusha okuluhlaza.
Emkhakheni wobuchwepheshe bokuthutha izitimela, ukukala isisindo esincane sezimoto, okungukuthi, ukunciphisa isisindo somzimba ngangokunokwenzeka ngaphansi kwesisekelo sokuqinisekisa ukusebenza kwezimoto nokunciphisa ukusetshenziswa kwamandla okusebenza, ubuchwepheshe obuyisihluthulelo sokufeza ukwenziwa luhlaza kanye nokunciphisa i-carbonization yezimoto zesitimela.
Izimoto zesitimela ezivamile ezisetshenziswa kakhuluinsimbi, i-aluminium alloy nezinye izinto zensimbi,ivinjelwe yizakhiwo zezinto ezibonakalayo, ibhekene nobunzima bokunciphisa isisindo. I-carbon fiber, ngenxa yokukhanya kwayo okulula, amandla aphezulu, ukulwa nokukhathala, ukumelana nokugqwala nezinye izinzuzo, eyaziwa ngokuthi “inkosi yezinto ezintsha”, amandla ayo angaphezu kokuphindwe kahlanu kunensimbi, kodwa isisindo singaphansi kwengxenye eyodwa kwezine yensimbi, iyinto enhle kakhulu yezimoto zesitimela ezilula.
I-CRRC Sifang Co., Ltd, kanye neQingdao Metro Group kanye nezinye izikhungo, babhekane nobuchwepheshe obubalulekile njengokuklama okuhlanganisiwe kwe-i-carbon fiberisakhiwo esithwala umthwalo esiyinhloko, ukubumba nokukhiqiza okusebenzayo nokungabizi kakhulu, ukuhlolwa nokugcinwa okuhlakaniphile okuzungezile, futhi kwaxazululwa ngokuhlelekile izinkinga zokusetshenziswa kobunjiniyela, kwafezwa ukusetshenziswa kwezinto ezihlanganisiwe ze-carbon fiber esakhiweni esithwala umthwalo esiyinhloko sezimoto zezentengiselwano ze-metro okokuqala ngqa emhlabeni.
Umzimba wesitimela sesitimela esingaphansi komhlaba, uhlaka lwe-bogie kanye nezinye izakhiwo eziyinhloko zokuthwala izinto zenziweizinto ezihlanganisiwe ze-carbon fiber, sibona ukuthuthukiswa okusha kokusebenza kwezimoto, ngokukhanya okulula nokonga amandla kakhudlwana, amandla aphezulu, ukuqina kwemvelo okuqinile, izindleko zokusebenza nokugcinwa komjikelezo wokuphila wonke kanye nezinye izinzuzo zobuchwepheshe eziphansi.
Ilula Kakhulu Futhi Isebenzisa Amandla Kakhulu
Ngokusebenzisaizinto ezihlanganisiwe ze-carbon fiber, imoto ifinyelele ekunciphiseni okukhulu kwesisindo. Uma kuqhathaniswa nemoto yendabuko yensimbi, isisindo somzimba semoto yesitimela se-carbon fiber sincishisiwe ngo-25%, isisindo se-bogie frame sincishisiwe ngo-50%, isisindo semoto yonke sincishisiwe cishe ngo-11%, ukusetshenziswa kwamandla ngo-7%, isitimela ngasinye singanciphisa ukukhishwa kwe-carbon dioxide okungamathani angaba ngu-130 ngonyaka, okulingana namahektha ayi-101 okutshala amahlathi.
Amandla Aphakeme Nokuphila Okude Kwesakhiwo
Isitimela sase-Subway samukela ukusebenza okuphezulu okushaizinto ezihlanganisiwe ze-carbon fiber, ifinyelela ukukhululeka ngenkathi ithuthukisa amandla omzimba. Ngesikhathi esifanayo, uma kuqhathaniswa nokusetshenziswa kwezinto zensimbi zendabuko, izingxenye zohlaka lwe-bogie ze-carbon fiber zinamandla okumelana nokushaqeka, ukumelana nokukhathala okungcono, okwandisa impilo yenkonzo yesakhiwo.
Ukuqina Okukhulu Kwemvelo
Umzimba olula wenza isitimela sikwazi ukushayela kangcono, okungagcini nje ngokuhlangabezana nezidingo zokunciphisa isisindo se-axle eziqinile zemigqa, kodwa futhi kunciphisa ukuguguleka kwamasondo namathrekhi. Imoto iphinde isebenzise ubuchwepheshe obuthuthukisiwe be-radial esebenzayo, obungalawula amasondo emoto ngenkuthalo ukuthi adlule egobileni elihambisana ne-radial, okunciphisa kakhulu ukuguguleka nomsindo wamasondo nesitimela.Amadiski ebhuleki e-carbon ceramic, ezimelana kakhulu nokuguguleka nokushisa, zisetshenziselwa ukunciphisa isisindo ngenkathi zihlangabezana nezidingo zokusebenza kokubhuleka ezidinga kakhulu.
Izindleko Zokusebenza Nokunakekela Eziphansi Zomjikelezo Wokuphila
Ngokusebenzisaizinto ezilula ze-carbon fiberkanye nobuchwepheshe obusha, ukuguguleka kwamasondo nezitimela ze-metro ze-carbon fiber kuncishiswe kakhulu, okunciphisa kakhulu ukugcinwa kwezimoto namathrekhi. Ngesikhathi esifanayo, ngokusebenzisa ubuchwepheshe obuphindwe kabili bedijithali, ipulatifomu yokusebenza nokugcinwa okuhlakaniphile kwe-SmartCare yezitimela ze-carbon fiber iye yaqaphela ukuzitholela nokuzihlola kokuphepha, impilo yesakhiwo kanye nokusebenza kwemoto yonke, yathuthukisa ukusebenza kahle kokusebenza nokugcinwa, futhi yanciphisa izindleko zokusebenza nokugcinwa. Izindleko zokugcinwa kwesitimela sonke zincishiswe ngo-22%.
Emkhakheni wobuchwepheshe be-carbon fiber yezimoto zesitimela, i-CRRC Sifang Co., Ltd, isebenzisa amandla ayo ezimboni, yakhe ipulatifomu ye-R&D egcwele uchungechunge, ukukhiqiza kanye nokuqinisekisa ngeminyaka engaphezu kwe-10 yokuqongelela i-R&D kanye nokusungula izinto ngokubambisana "kwesicelo socwaningo lwemboni-yunivesithi", yakha isethi ephelele yamakhono obunjiniyela kusukelai-carbon fiberukwakheka kwesakhiwo kanye ne-R&D ekubumbeni nasekukhiqizeni, ekulingiseni, ekuhloleni, ekuqinisekiseni ikhwalithi, njll., kanye nokuhlinzeka ngesisombululo sokuma okukodwa somjikelezo wokuphila wemoto. Nikeza isisombululo sokuma okukodwa somjikelezo wokuphila wonke.
Okwamanje, i-i-carbon fiberIsitimela sesitimela esingaphansi komhlaba sesiqedile ukuhlolwa kohlobo lwefektri. Ngokusho kohlelo, sizofakwa ekusebenzeni kokuboniswa kwabagibeli eQingdao Metro Line 1 ngonyaka.
Njengamanje, emkhakheni wezokuthutha izitimela zasemadolobheni eShayina, indlela yokunciphisa ukusetshenziswa kwamandla, ukunciphisa ukukhishwa kwekhabhoni, nokudala isitimela sasemadolobheni esiluhlaza esisebenza kahle kakhulu nesingenakhabhoni eningi kuyinto eza kuqala ekuthuthukisweni kwale mboni. Lokhu kubeka phambili isidingo esikhulu sobuchwepheshe obulula bezimoto zesitimela.
Ukwethulwa kwezentengiselwanoi-carbon fiberisitimela sangaphansi komhlaba, ukukhuthaza isakhiwo esiyinhloko sokuthwala izimoto zangaphansi komhlaba kusukela ensimbi, i-aluminium alloy nezinye izinto zensimbi zendabuko kuya ekuphindaphindweni kwezinto ezintsha ze-carbon fiber, ukuphula imbobo yesakhiwo sensimbi yendabuko ukunciphisa isisindo, ukufeza ukuthuthukiswa okusha kobuchwepheshe obulula besitimela sangaphansi komhlaba saseShayina, kuzokhuthaza ukuguqulwa okuluhlaza okotshani kanye nokuguqulwa kwe-carbon ephansi kwezokuthutha kwesitimela sasemadolobheni saseShayina, kusize imboni yezitimela zasemadolobheni ukufeza "i-carbon ephindwe kabili". Izodlala indima ebalulekile ekukhuthazeni ukuguqulwa okuluhlaza okotshani kanye nokuguqulwa kwe-carbon ephansi kwezokuthutha kwesitimela sasemadolobheni saseShayina nokusiza imboni yezitimela zasemadolobheni ukufeza umgomo "we-carbon ephindwe kabili".
