Ngomhla wama-26 kuJuni, uloliwe we-metro osebenzisa i-carbon fiber “CETROVO 1.0 Carbon Star Express” owenziwe yiCRRC Sifang Co., Ltd kunye neQingdao Metro Group kwiQingdao Subway Line 1 wakhutshwa ngokusesikweni eQingdao, olu loliwe wokuqala we-carbon fiber emhlabeni osetyenziselwa ukusebenza kwezorhwebo. Lo loliwe we-metro ukhaphukhaphu nge-11% kunezithuthi zemveli ze-metro, unezibonelelo ezibalulekileyo ezifana nokukhanya kancinci nokonga amandla, nto leyo ekhokelela ukuba uloliwe we-metro afumane uphuculo olutsha oluluhlaza.
Kwicandelo lobuchwepheshe bothutho lwezithuthi zikaloliwe, ukunciphisa ubunzima bezithuthi, oko kukuthi, ukunciphisa ubunzima bomzimba kangangoko kunokwenzeka phantsi kwengcamango yokuqinisekisa ukusebenza kwezithuthi kunye nokunciphisa ukusetyenziswa kwamandla okusebenza, yeyona teknoloji iphambili yokufezekisa uhlaza kunye nokunciphisa i-carbonization yezithuthi zikaloliwe.
Iimoto zemveli ezingaphantsi komhlaba zisebenzisa ikakhuluintsimbi, i-aluminium alloy kunye nezinye izinto zesinyithi,ithintelwe ziimpawu zezinto eziphathekayo, ijongene nomqobo wokunciphisa ubunzima. I-carbon fiber, ngenxa yokukhanya kwayo okukhaphukhaphu, amandla aphezulu, ukulwa nokudinwa, ukumelana nokugqwala kunye nezinye izibonelelo, eyaziwa ngokuba "ngukumkani wezinto ezintsha", amandla ayo angaphezulu ngokuphindwe kahlanu kunentsimbi, kodwa ubunzima bayo bungaphantsi kwe-1/4 yentsimbi, sisixhobo esifanelekileyo kwizithuthi zikaloliwe ezikhaphukhaphu.
I-CRRC Sifang Co., Ltd, kunye neQingdao Metro Group kunye nezinye iiyunithi, bajongane nobuchwepheshe obuphambili obufana noyilo oludibeneyo lweifayibha yekhabhoniisakhiwo esiphambili esithwala umthwalo, ukubumba kunye nokuvelisa okusebenzayo nokungabizi kakhulu, uhlolo olukrelekrele kunye nokugcinwa, kwaye isombulule iingxaki zokusetyenziswa kobunjineli ngokucwangcisiweyo, saza safezekisa ukusetyenziswa kwezinto ezidityanisiweyo ze-carbon fiber kwisakhiwo esiphambili esithwala umthwalo kwizithuthi ze-metro zorhwebo okokuqala ngqa emhlabeni.
Umzimba wesitimela esingaphantsi komhlaba, ifreyimu yebogie kunye nezinye izakhiwo eziphambili zeebhereyitha zenziweizixhobo ezidityanisiweyo zefayibha yekhabhoni, sifezekisa uphuculo olutsha lokusebenza kwezithuthi, ngokukhanya okuncinci nokonga amandla, amandla aphezulu, ukuqina okuqinileyo kokusingqongileyo, iindleko zokusebenza nokugcinwa komjikelo wobomi bonke kunye nezinye izibonelelo zobugcisa.
Ilula kwaye inamandla angakumbi
Ngokusebenzisaizixhobo ezidityanisiweyo zefayibha yekhabhoni, isithuthi sifikelele ekunciphiseni ubunzima obukhulu. Xa kuthelekiswa nesithuthi semveli sesinyithi esisetyenziswa ngaphantsi komhlaba, ukunciphisa ubunzima bomzimba wesithuthi esisetyenziswa ngaphantsi komhlaba esine-carbon fiber ngama-25%, ukunciphisa ubunzima besakhelo se-bogie ngama-50%, ukunciphisa ubunzima besithuthi siphela malunga ne-11%, ukusetyenziswa kwamandla nge-7%, uloliwe ngamnye unokunciphisa ukukhutshwa kwe-carbon dioxide malunga neetoni ezili-130 ngonyaka, okulingana neehektare ezili-101 zokuhlwayela amahlathi.
Amandla Aphezulu kunye nobomi obude besakhiwo
Isitimela saseSubway samkela ukusebenza okuphezulu okutshaizixhobo ezidityanisiweyo zefayibha yekhabhoni, ifumana ukukhanya okukhaphukhaphu ngelixa iphucula amandla omzimba. Kwangaxeshanye, xa kuthelekiswa nokusetyenziswa kwezinto zesinyithi zemveli, izixhobo zesakhelo se-bogie se-carbon fiber zinamandla okumelana nempembelelo, zikwazi ukumelana nokudinwa ngcono, zandisa ubomi benkonzo yesakhiwo.
Ukuqina Okukhulu Kwendalo Esingqongileyo
Umzimba olula uvumela uloliwe ukuba usebenze ngcono ekuqhubeni, okungapheleli nje ekuhlangabezaneni neemfuno ezingqongqo zokunciphisa ubunzima be-axle kwimigca, kodwa kunciphisa nokukrazuka kwamavili kunye neetrekhi. Isithuthi sikwasebenzisa ubuchwepheshe obuphambili be-radial esebenzayo, obunokulawula ngokukhutheleyo amavili esithuthi ukuba adlule kwigophe kwicala le-radial, nto leyo enciphisa kakhulu ukukrazuka kunye nengxolo yamavili kunye neereli.Iidiski zeebhuleki ze-ceramic ze-carbon ceramic, ezikwaziyo ukumelana nokuguguleka nobushushu, zisetyenziselwa ukunciphisa ubunzima ngelixa zihlangabezana neemfuno zokusebenza kokubhuleka ezifuna amandla amaninzi.
Iindleko Zokusebenza Nokugcina Ubomi Bomntu Eziphantsi
Ngokusebenzisaizixhobo ezilula zefayibha yekhabhonikunye nobuchwepheshe obutsha, ukuguguleka kwamavili kunye noololiwe boololiwe be-metro be-carbon fiber kuncitshiswe kakhulu, nto leyo enciphisa kakhulu ukugcinwa kwezithuthi kunye neetrekhi. Kwangaxeshanye, ngokusebenzisa itekhnoloji yedijithali ezimbini, iqonga lokusebenza kunye nokugcinwa kweSmartCare elikrelekrele loololiwe be-carbon fiber liye laqonda ukuzibona kunye nokuzixilonga kokhuseleko, impilo yolwakhiwo kunye nokusebenza kwesithuthi sonke, laphucula ukusebenza kunye nokugcinwa kakuhle, kwaye lanciphisa iindleko zokusebenza kunye nokugcinwa. Ixabiso lokugcinwa kololiwe lonke lomjikelo wobomi lincitshisiwe ngama-22%.
Kwicandelo lobuchwepheshe be-carbon fiber kwizithuthi zikaloliwe, i-CRRC Sifang Co., Ltd, isebenzisa amandla ayo emizi-mveliso, yakhe iqonga elipheleleyo le-R&D, imveliso kunye ne-verification ngokusebenzisa iminyaka engaphezu kwe-10 yokuqokelela i-R&D kunye nophuhliso oluhlangeneyo "lwesicelo sophando-lweshishini-lweyunivesithi", yakha iseti epheleleyo yezakhono zobunjineli ezivelaifayibha yekhabhoniuyilo lwesakhiwo kunye nophando nophuhliso ukuya ekubumbeni nasekuveliseni, ekulinganiseni, ekuvavanyweni, ekuqinisekisweni komgangatho, njl.njl., kunye nokubonelela ngesisombululo sokuma kunye somjikelo wobomi bonke besithuthi. Nika isisombululo sokuma kunye somjikelo wobomi bonke.
Okwangoku, iifayibha yekhabhoniUloliwe ongaphantsi komhlaba ugqibile uvavanyo lohlobo lwefektri. Ngokwesicwangciso, uza kufakwa kumsebenzi wokubonisa abakhweli kwiQingdao Metro Line 1 kulo nyaka.
Okwangoku, kwicandelo lokuthuthwa koololiwe basezidolophini eTshayina, indlela yokunciphisa ukusetyenziswa kwamandla, ukunciphisa ukukhutshwa kwekhabhoni, kunye nokudala oololiwe basezidolophini abaluhlaza abasebenza kakuhle kakhulu nabangenakhabhoni iphantsi yeyona nto iphambili kuphuhliso lweli shishini. Oku kubeka phambili imfuno ephezulu yetekhnoloji ekhaphukhaphu kwizithuthi zikaloliwe.
Ukwaziswa kwezorhweboifayibha yekhabhoniUloliwe ongaphantsi komhlaba, ukukhuthaza isakhiwo esiphambili seebhereyitha zezithuthi ezingaphantsi komhlaba ukusuka kwintsimbi, i-aluminium alloy kunye nezinye izinto zesinyithi zemveli ukuya kwi-carbon fiber ukuphindaphinda kwezinto ezintsha, ukwaphula i-bottleneck yesakhiwo sesinyithi sendabuko ukunciphisa ubunzima, ukufezekisa uphuculo olutsha lwetekhnoloji elula yesitimela esingaphantsi komhlaba saseTshayina, kuya kukhuthaza utshintsho oluluhlaza nolunekhabhoni ephantsi kwezothutho lukaloliwe lwasezidolophini lwaseTshayina, kuncede ishishini likaloliwe lasezidolophini ukuba lifezekise "ikhabhoni ezimbini. Iya kudlala indima ebalulekileyo ekukhuthazeni utshintsho oluluhlaza nolunekhabhoni ephantsi kwezothutho lukaloliwe lwasezidolophini lwaseTshayina kunye nokunceda ishishini likaloliwe lasezidolophini lifezekise injongo "yekhabhoni ezimbini".
