izwe lami lenze izinguquko ezinkulu emkhakheni we-high-speed maglev. Ngomhla zingama-20 kuJulayi, uhlelo lwezwe lwakithi lwesivinini esingu-600 km/h lwesivinini esikhulu se-maglev, olwakhiwa yi-CRRC futhi olunamalungelo empahla yengqondo ezimele ngokuphelele, lwakhishwa ngempumelelo emgqeni womhlangano e-Qingdao. Lolu uhlelo lwezokuthutha lwe-maglev lokuqala emhlabeni oluklanyelwe ukufinyelela ku-600 km/h. izwe lami seliyingcweti eqoqweni eliphelele lobuchwepheshe be-maglev obunesivinini esikhulu namandla obunjiniyela.
Ukuze ukwazi kahle ubuchwepheshe obubalulekile be-maglev yesivinini esikhulu, ngaphansi kokusekelwa Kohlelo Lweminyaka Engu-13 Lokucwaninga Nokuthuthukiswa Olubalulekile Lomnyango Wesayensi Nobuchwepheshe, i-Advanced Rail Transit Key Special Project, ehlelwe yi-CRRC futhi eholwa yi-CRRC Sifang Co., Ltd., ihlanganisa ndawonye ngaphezu kwe-30 maglev yasekhaya kanye nesivinini esiphezulu. Amanyuvesi, izikhungo zocwaningo kanye namabhizinisi "ukukhiqiza, ukutadisha, ucwaningo kanye nokusetshenziswa" ngokuhlanganyela kwethula ukuthuthukiswa kohlelo lwezokuthutha lwe-maglev olunesivinini esingamakhilomitha angu-600 ngehora.
Le phrojekthi yethulwa ngo-Okthoba 2016, futhi i-prototype yokuhlola yathuthukiswa ngo-2019. Yahlolwa ngempumelelo kulayini wokuhlola weNyuvesi yase-Tongji e-Shanghai ngoJuni 2020. Ngemva kokulungiswa kwesistimu, kwanqunywa uhlelo lokugcina lobuchwepheshe futhi kwasungulwa uhlelo oluphelele ngoJanuwari 2021. Futhi kwaqala izinyanga eziyisithupha ukulungisa amaphutha ngokuhlanganyela kanye nokuhlolwa okuhlangene.
Kuze kube manje, ngemva kweminyaka emi-5 yocwaningo, uhlelo lwezokuthutha lwe-maglev oluhamba ngesivinini esiphezulu lwe-600km/h lwethulwa ngokusemthethweni, lwanqoba ngempumelelo ubuchwepheshe obuyinhloko, futhi uhlelo luxazulule izinkinga zokuthuthukiswa kwesivinini, ukuguquguquka kwemvelo okuyinkimbinkimbi, kanye nokusebenza kwendawo okuyisisekelo, kanye nokuhlanganiswa kwesistimu, izimoto, kanye nokudonsa. Ukuphumelela okukhulu kumasethi aphelele obuchwepheshe bonjiniyela njengokuphakelwa kwamandla, ukuxhumana kokulawula ukusebenza, namathrekhi olayini.
Ngithuthukise ngokuzimela amasethi okuqala angu-5 ezwe lami angamakhilomitha angu-600 ngehora izitimela ezinobunjiniyela be-maglev ezinesivinini esikhulu. Uhlobo olusha lwekhanda kanye nesixazululo se-aerodynamic kwathuthukiswa ukuze kuxazululwe izinkinga ze-aerodynamic ngaphansi kwezimo ze-ultra-high speed. Kusetshenziswa ubuchwepheshe obuthuthukisiwe be-laser hybrid welding kanye nobuchwepheshe be-carbon fibre, umzimba wemoto ongasindi futhi onamandla aphezulu ohlangabezana nezidingo ze-ultra-high-speed high-speed air-tight load-bearing. Isiqondiso sokumiswa esithuthukiswe ngokuzimela kanye namadivayisi okumisa isivinini, futhi ukunemba kokulawula kufinyelele kuleveli ehamba phambili yamazwe ngamazwe. Dlulisa inqubo yokukhiqiza eyinhloko futhi ubambe ubuchwepheshe bokukhiqiza bezingxenye ezibalulekile ezinjengohlaka olumisiwe, uzibuthe kagesi nesilawuli.
Nqoba ubuchwepheshe obubalulekile obufana nesiguquli sokudonsa se-IGCT samandla aphezulu kanye nokulawula ukudonsa okunembe kakhulu kokuvumelanisa, futhi uqedele ukuthuthukiswa okuzimele kwesistimu yokuphakela amandla okudonsa kwe-maglev enesivinini esikhulu. Ingcweti kubuchwepheshe obubalulekile bokuxhumana kwemoto kuya phansi ngaphansi kwezimo zesivinini esikhulu, njengokudluliswa kokulibaziseka okuphansi kakhulu nokulawulwa kokunikezelwa kwengxenye, futhi usungule futhi usungule uhlelo lokulawula ukuthutha lwe-maglev olunesivinini esikhulu oluvumelana nokusebenza kokulandela ngomkhondo okuzenzakalelayo komugqa webanga elide. I-beam entsha yethrekhi enembayo enelisa ukuhamba kwezitimela ngesivinini esiphezulu nokushelelayo isithuthukisiwe.
Qamba kabusha ekuhlanganisweni kwesistimu, unqamule izingqinamba zobuchwepheshe ezimweni zohlelo lokusebenza kanye nokuvumelana nezimo eziyinkimbinkimbi, ukuze i-maglev yesivinini esiphezulu ikwazi ukuhlangabezana nezidingo zezicelo zebanga elide, zokuhamba nokuhamba ngezimo eziningi, futhi ivumelane nezimo eziyinkimbinkimbi zejografi nezesimo sezulu ezifana nemigudu yemifula, ukubanda okuphezulu, izinga lokushisa eliphezulu kanye nomswakama ophezulu.
Njengamanje, uhlelo lwezokuthutha lwe-maglev oluhamba ngesivinini esiphezulu lwamakhilomitha angu-600 ngehora seluqedile ukuhlanganisa kanye nokulungiswa okuhlanganyelwe kwesistimu, futhi izitimela ezinhlanu ze-marshalling ziye zaqaphela ukumiswa okuzinzile nokusebenza okuguquguqukayo kulayini wokugunyazwa kwezitshalo, ngokusebenza okuhle kokusebenza.
Ngokuka-Ding Sansan, unjiniyela omkhulu wezobuchwepheshe wephrojekthi ye-maglev enesivinini esikhulu kanye nesekela likanjiniyela omkhulu we-CRRC Sifang Co., Ltd., i-maglev enesivinini esikhulu ephuma emgqeni womhlangano iwuhlelo lokuqala lomhlaba lokuthutha lwe-maglev olunesivinini esingamakhilomitha angu-600 ngehora. Umgomo oyisisekelo wokwamukela ubuchwepheshe bokuqondisa obujwayelekile obuvuthiwe nobuthembekile ukusebenzisa ukukhanga kazibuthe ukuze wenze isitimela sizulazule kuthrekhi ukuze senze umsebenzi ongathinteki. Inezinzuzo zezobuchwepheshe zokusebenza kahle okuphezulu, okusheshayo, okuphephile nokwethenjelwa, umthamo wezokuthutha oqinile, i-marshalling eguquguqukayo, ukhululekile ngesikhathi, ukulungiswa okulula, nokuvikelwa kwemvelo.
I-maglev enesivinini esikhulu enesivinini esingamakhilomitha angama-600 ngehora iyimoto yaphansi esheshayo etholakalayo njengamanje. Ibalwa ngokwesikhathi sangempela sokuhamba “umnyango nomuzi”, iyindlela yokuthutha eshesha kakhulu ebangeni elingamakhilomitha angu-1,500.
Yamukela isakhiwo sokusebenza "sesitimela sokubamba imoto", esiphephile futhi esithembekile. Uhlelo lokunikezwa kwamandla okudonsa luhlelwa phansi, futhi amandla anikezwa ngezigaba ngokuya ngokuma kwesitimela. Isitimela esisodwa kuphela esigijima esigabeni esiseduze, futhi empeleni ayikho ingozi yokushayisana kwengemuva. Thola ukusebenza okuzenzakalelayo ngokugcwele kwezinga le-GOA3, futhi ukuvikelwa kokuphepha kwesistimu kuhlangabezana nemfuneko yezinga eliphezulu lokuphepha le-SIL4.
Isikhala sivulekile futhi ukugibela kukhululekile. Ingxenye eyodwa ingathwala abagibeli abangaphezu kwe-100, futhi ingahlanganiswa kalula phakathi kwezimoto ezi-2 kuya kweziyi-10 ukuze kuhlangatshezwane nezidingo zabagibeli abahlukahlukene.
Akukho ukuthintana nethrekhi ngesikhathi sokushayela, akukho ukuguga kwamasondo noma ujantshi, ukulungiswa okuncane, isikhathi eside sokulungisa, nomnotho omuhle kuwo wonke umjikelezo wempilo.
Njengendlela yezokuthutha enesivinini esikhulu, i-maglev enesivinini esikhulu ingaba enye yezindlela ezisebenzayo zokuhamba ngesivinini esiphezulu nezisezingeni eliphezulu, enothisa inethiwekhi yezokuthutha yezwe lami enezinhlangothi ezintathu.
Izimo zohlelo lwayo lokusebenza zihlukahlukene, futhi ingasetshenziselwa ukugcwala kwabagibeli abanesivinini esikhulu kuma-agglomerations emadolobheni, ithrafikhi ehlanganisiwe phakathi kwamadolobha asemqoka, kanye nethrafikhi yephaseji enoxhumo olude nolusebenzayo. Njengamanje, siyakhula isidingo sokuhamba ngesivinini esiphezulu sokuhamba kwabagibeli bebhizinisi, ukuhamba kwezivakashi kanye nokuhamba kwabagibeli abagibelayo okulethwa ukuthuthukiswa komnotho wezwe lami. Njengesengezo esiwusizo kwezokuthutha ezihamba ngesivinini esiphezulu, i-maglev yesivinini esiphezulu ingahlangabezana nezidingo zokuvakasha ezihlukahlukene futhi ikhuthaze intuthuko ehlelekile yokuhlanganisa umnotho wesifunda.
Kuyaqondakala ukuthi, igxile kwezobunjiniyela nokuthuthukiswa kwezimboni, i-CRRC Sifang yakhe isikhungo sokuhlola esihlanganisiwe se-maglev esinesivinini esiphezulu kanye nesikhungo sokukhiqiza isilingo ku-National High-speed Train Technology Innovation Center. Iyunithi yokubambisana phakathi kweNhlangano Yezizwe Ezihlangene yakha izimoto, ugesi odonsayo, ukuxhumana kokulawula ukusebenza, kanye nolayini. Ukulandelela ukulingisa kwesistimu yangaphakathi kanye nenkundla yokuhlola yakhe uchungechunge lwezimboni lwendawo kusukela ezingxenyeni eziyinhloko, amasistimu angukhiye kuya ekuhlanganisweni kwesistimu.
