Izwe lami lenze intuthuko enkulu emkhakheni we-maglev eshesha kakhulu. Ngomhlaka-20 Julayi, uhlelo lokuthuthwa kwe-maglev eshesha kakhulu lwezwe lami oluhamba ngamakhilomitha angu-600/h, olwathuthukiswa yi-CRRC futhi lunamalungelo obunikazi obuzimele ngokuphelele, lwasuswa ngempumelelo emgqeni wokuhlanganisa eQingdao. Lolu uhlelo lokuqala lokuthuthwa kwe-maglev eshesha kakhulu emhlabeni olwakhelwe ukufinyelela ku-600 km/h. Izwe lami selikwazile ukuqoqa ulwazi oluphelele lwamakhono obuchwepheshe be-maglev eshesha kakhulu kanye nobunjiniyela.
Ukuze kufundiswe ubuchwepheshe obubalulekile be-maglev eshesha kakhulu, ngaphansi kokusekelwa koHlelo Locwaningo Nokuthuthukiswa Kwesihluthulelo Sikazwelonke lwe-“13th Five-Year” loMnyango Wezesayensi Nobuchwepheshe, i-Advanced Rail Transit Key Special Project, ehlelwe yi-CRRC futhi eholwa yi-CRRC Sifang Co., Ltd., ihlanganisa ndawonye amasimu esitimela e-maglev asekhaya angaphezu kwama-30 kanye nesitimela esisheshayo. Amanyuvesi, izikhungo zocwaningo kanye namabhizinisi “ukukhiqiza, ukutadisha, ucwaningo kanye nokusetshenziswa” baqalise ngokubambisana ukuthuthukiswa kohlelo lokuthutha lwe-maglev eshesha kakhulu ngesivinini samakhilomitha angu-600 ngehora.
Le phrojekthi yaqalwa ngo-Okthoba 2016, kwathi kwasungulwa uhlobo lokuhlola ngo-2019. Yahlolwa ngempumelelo emgqeni wokuhlola we-Tongji University eShanghai ngoJuni 2020. Ngemva kokwenziwa ngcono kwesistimu, kwanqunywa uhlelo lokugcina lobuchwepheshe kwathi uhlelo oluphelele lwathuthukiswa ngoJanuwari 2021. Kwaqalwa ukuhlolwa kokulungisa amalunga izinyanga eziyisithupha kanye nokuhlolwa kwamalunga.
Kuze kube manje, ngemva kweminyaka emihlanu yocwaningo, uhlelo lokuthuthwa kwe-maglev oluhamba ngesivinini esikhulu oluhamba ngamakhilomitha angu-600/h lwethulwe ngokusemthethweni, lwanqoba ngempumelelo ubuchwepheshe obuyinhloko, futhi uhlelo lwaxazulula izinkinga zokuthuthukiswa kwesivinini, ukuzivumelanisa nezimo okuyinkimbinkimbi kwemvelo, kanye nokwenziwa kwendawo kwesistimu ebalulekile, futhi lwaqaphela ukuhlanganiswa kwesistimu, izimoto, kanye nokubambelela. Intuthuko enkulu kumasethi aphelele obuchwepheshe bobunjiniyela njengokunikezwa kwamandla, ukuxhumana kokulawula ukusebenza, kanye namathrekhi omugqa.
Ngathuthukisa ngokuzimela amasethi okuqala ama-5 ezwe lami ezitimela ezisebenzisa i-maglev ezisheshayo ezingamakhilomitha angu-600 ngehora. Kwakhiwe uhlobo olusha lwekhanda kanye nesisombululo se-aerodynamic ukuze kuxazululwe izinkinga ze-aerodynamic ngaphansi kwezimo zesivinini esikhulu kakhulu. Kusetshenziswa ubuchwepheshe obuthuthukisiwe be-laser hybrid welding kanye ne-carbon fiber, umzimba wemoto olula futhi onamandla aphezulu ohlangabezana nezidingo ze-high-high-air-tight-load-bearing used. Kwakhiwe ngokuzimela amadivayisi okuqondisa ukumiswa kanye nokulinganisa isivinini, futhi ukunemba kokulawula sekufinyelele ezingeni eliholayo emhlabeni jikelele. Phuma enkambisweni yokukhiqiza ebalulekile futhi ube yingcweti kubuchwepheshe bokukhiqiza bezingxenye ezibalulekile eziyinhloko njengohlaka lokumiswa, i-electromagnet kanye nesilawuli.
Nqoba ubuchwepheshe obubalulekile njenge-converter ye-traction ye-IGCT enamandla aphezulu kanye nokulawula ukudonsa okuqondile okunembile, futhi uqedele ukuthuthukiswa okuzimele kohlelo lokuphakelwa kwamandla e-maglev olusheshayo. Qonda ubuchwepheshe obubalulekile bokuxhumana phakathi kwezimoto nomhlaba ngaphansi kwezimo zesivinini esikhulu, njengokudlulisa ukubambezeleka okuphansi kakhulu kanye nokulawula ukudluliselwa kwezingxenye, futhi usungule futhi usungule uhlelo lokulawula ukuthutha kwe-maglev olusheshayo oluvumelana nokusebenza kokulandelela okuzenzakalelayo komugqa we-trunk webanga elide. Kuthuthukiswe umsebe omusha wethrekhi onembile ohlangabezana nokusebenza kwezitimela ngesivinini esikhulu nangokushelela.
Shintsha ekuhlanganisweni kwesistimu, dlula ezinkingeni zobuchwepheshe ezimweni zokusetshenziswa kanye nokuzivumelanisa nezimo zemvelo eziyinkimbinkimbi, ukuze i-maglev enesivinini esikhulu ikwazi ukuhlangabezana nezidingo zezinhlelo zokusebenza zebanga elide, ukuhamba ngezinyawo kanye nezimo eziningi, futhi ivumelane nezimo zezwe nezimo zezulu eziyinkimbinkimbi njengemihubhe yemifula, ukubanda okuphezulu, izinga lokushisa eliphezulu kanye nomswakama ophezulu.
Njengamanje, uhlelo lokuthuthwa kwe-maglev oluhamba ngamakhilomitha angu-600 ngehora seluqedile ukuhlanganiswa kanye nokulungiswa kokuhlanganiswa kohlelo, kanti izitimela ezinhlanu zokuqondisa sezikwazile ukumiswa okuzinzile kanye nokusebenza okuguquguqukayo emugqeni wokufaka imishini ngaphakathi kwesitshalo, ngokusebenza okuhle.
Ngokusho kukaDing Sansan, unjiniyela oyinhloko wephrojekthi ye-maglev eshesha kakhulu kanye nephini lonjiniyela oyinhloko we-CRRC Sifang Co., Ltd., i-maglev eshesha kakhulu ephuma emgqeni wokuhlanganisa iyisistimu yokuqala yokuthutha i-maglev eshesha kakhulu emhlabeni enesivinini samakhilomitha angu-600 ngehora. Isimiso esiyisisekelo sokwamukela ubuchwepheshe obujwayelekile obuvuthiwe nobunokwethenjelwa ukusebenzisa ukukhanga kwe-electromagnetic ukwenza isitimela sikhuphukele emzileni ukuze sisebenze ngaphandle kokuthintana. Inezinzuzo zobuchwepheshe zokusebenza kahle okuphezulu, okusheshayo, okuphephile nokuthembekile, amandla okuthutha aqinile, ukuqondisa okuguquguqukayo, ukunethezeka ngesikhathi, ukulungiswa okulula, kanye nokuvikelwa kwemvelo.
I-maglev enesivinini esikhulu enejubane lamakhilomitha angu-600 ngehora iyimoto ehamba phansi esheshayo kakhulu engatholakala njengamanje. Uma ibalwa ngokwesikhathi sangempela sokuhamba "umnyango nomnyango", iyindlela yokuhamba eshesha kakhulu ebangeni lamakhilomitha angu-1,500.
Yamukela isakhiwo sokusebenza "sesitimela esibamba imoto", esiphephile futhi esithembekile. Uhlelo lokuphakelwa kwamandla okudonsa luhlelwe phansi, futhi amandla anikezwa ngezigaba ngokuya ngendawo yesitimela. Isitimela esisodwa kuphela esisebenza engxenyeni eseduze, futhi empeleni akukho bungozi bokushayisana kwangemuva. Qaphela ukusebenza okuzenzakalelayo kwezinga le-GOA3, futhi ukuvikelwa kokuphepha kohlelo kuhlangabezana nesidingo sezinga eliphezulu lokuphepha le-SIL4.
Indawo inkulu futhi uhambo lukhululekile. Ingxenye eyodwa ingathwala abagibeli abangaphezu kwe-100, futhi ingahlukaniswa kalula ngezimoto ezimbili kuya kweziyi-10 ukuze kuhlangatshezwane nezidingo zabagibeli abahlukahlukene.
Akukho ukuthintana nomzila ngesikhathi sokushayela, akukho ukuguguleka kwesondo noma kwesitimela, ukulungiswa okuncane, isikhathi eside sokulungisa, kanye nokugcina kahle impilo yonke.
Njengendlela yokuhamba ngesivinini esikhulu, i-maglev yesivinini esikhulu ingaba enye yezindlela ezisebenzayo zokuhamba ngesivinini esikhulu nekhwalithi ephezulu, okucebisa inethiwekhi yezokuthutha ephelele yezwe lami enezinhlangothi ezintathu.
Izimo zokusetshenziswa kwayo ziyahlukahluka, futhi ingasetshenziswa ekuthuthweni kwabagibeli abasheshayo ezindaweni zasemadolobheni, ekuthuthweni okuhlanganisiwe phakathi kwamadolobha amakhulu, kanye nasekuthuthweni kwemigwaqo enokuxhumana okude nokusebenzayo. Njengamanje, isidingo sokuhamba ngesivinini esikhulu ngokugeleza kwabagibeli bebhizinisi, ukugeleza kwezivakashi kanye nokugeleza kwabagibeli abasheshayo okubangelwa intuthuko yezomnotho yezwe lami siyanda. Njengesengezo esiwusizo kwezokuthutha ngesivinini esikhulu, i-maglev eshesha kakhulu ingahlangabezana nezidingo zokuhamba ezahlukahlukene futhi ikhuthaze intuthuko ehlelekile yokuhlanganiswa komnotho wesifunda.
Kuyaqondakala ukuthi, ngokugxila kobunjiniyela kanye nokuthuthukiswa kwezimboni, i-CRRC Sifang yakhe isikhungo sobuchwepheshe sokuhlola esihlanganisiwe se-maglev esinejubane eliphezulu kanye nesikhungo sokukhiqiza ukuhlolwa eSikhungweni Sikazwelonke Sokusungula Ubuchwepheshe Besitimela Esisheshayo. Iyunithi yokubambisana ngaphakathi kweZizwe Ezihlangene yakhe izimoto, ukunikezwa kwamandla okudonsa, ukuxhumana kokulawula ukusebenza, kanye nemigqa. Ukulingisa uhlelo lwangaphakathi lwethrekhi kanye nepulatifomu yokuhlola yakhe uchungechunge lwezimboni olusendaweni kusukela ezingxenyeni eziyinhloko, izinhlelo ezibalulekile kuya ekuhlanganisweni kwesistimu.
