Mu ukadaulo wa mayendedwe a sitima, kulemera pang'ono kwa magalimoto, mwachitsanzo, kuchepetsa kulemera kwa thupi momwe zingathere poganizira kuti magalimoto akuyenda bwino komanso kuchepetsa kugwiritsa ntchito mphamvu, ndiye ukadaulo wofunikira kwambiri pakuzindikira kubiriwira komanso kuchepa kwa mpweya m'magalimoto a sitima.
Magalimoto achikhalidwe apansi panthaka amagwiritsa ntchito kwambirichitsulo, aluminiyamu ndi zinthu zina zachitsulo,yoletsedwa ndi zinthu zakuthupi, yomwe imayang'anizana ndi vuto la kuchepetsa kulemera. Ulusi wa kaboni, chifukwa cha kupepuka kwake, mphamvu zake zambiri, kukana kutopa, kukana dzimbiri ndi zabwino zina, zomwe zimadziwika kuti "mfumu ya zipangizo zatsopano", mphamvu zake ndi zoposa 5 kuposa chitsulo, koma kulemera kwake ndi kochepa kuposa 1/4 ya chitsulocho, ndi chinthu chabwino kwambiri pamagalimoto opepuka a sitima.

Thupi la sitima yapansi panthaka, chimango cha bogie ndi zinthu zina zazikulu zonyamulira katundu zimapangidwa ndizipangizo zopangidwa ndi ulusi wa kaboni, pozindikira kukweza kwatsopano magwiridwe antchito a galimoto, ndi yopepuka komanso yosagwiritsa ntchito mphamvu zambiri, yamphamvu kwambiri, yolimba kwambiri pa chilengedwe, yochepetsa ndalama zogwirira ntchito ndi kukonza moyo wonse komanso zabwino zina zaukadaulo.
Yopepuka komanso Yogwiritsa Ntchito Mphamvu Zambiri
Kudzera mu kugwiritsa ntchitozipangizo zopangidwa ndi ulusi wa kaboni, galimotoyo yachepetsa kwambiri kulemera kwake. Poyerekeza ndi galimoto yachikhalidwe yachitsulo, kulemera kwa thupi la galimoto yapansi panthaka ya carbon fiber ndi 25%, kulemera kwa bogie frame ndi 50%, kulemera konse kwa galimotoyo ndi pafupifupi 11%, kugwiritsa ntchito mphamvu ndi 7%, sitima iliyonse imatha kuchepetsa mpweya wa carbon dioxide wa matani pafupifupi 130 pachaka, wofanana ndi maekala 101 a nkhalango.
Mphamvu Zapamwamba ndi Moyo Wautali wa Kapangidwe
Sitima ya Subway yayamba kugwiritsa ntchito njira yatsopano yogwirira ntchito bwinozipangizo zopangidwa ndi ulusi wa kaboni, kukhala wopepuka pamene akulimbitsa mphamvu za thupi. Nthawi yomweyo, poyerekeza ndi kugwiritsa ntchito zipangizo zachitsulo zachikhalidwe, zigawo za chimango cha bogie cha ulusi wa kaboni zimakhala ndi mphamvu yolimba, kukana kutopa bwino, kukulitsa moyo wa ntchito ya nyumbayo.
Kulimba Kwambiri kwa Zachilengedwe
Thupi lopepuka limathandiza sitimayo kuyendetsa bwino, zomwe sizimangokwaniritsa zofunikira zoletsa kulemera kwa axle ya mizere, komanso zimachepetsa kuwonongeka ndi kung'ambika kwa mawilo ndi njanji. Galimotoyo imagwiritsanso ntchito ukadaulo wapamwamba wa radial, womwe umatha kuwongolera mawilo a galimotoyo kuti adutse m'mphepete motsatira njira ya radial, zomwe zimachepetsa kwambiri kuwonongeka ndi phokoso la mawilo ndi njanji.Ma disc a brake a ceramic a kaboni, zomwe sizimawonongeka ndi kutentha, zimagwiritsidwa ntchito kuchepetsa thupi pamene zikukwaniritsa zofunikira kwambiri pakugwira ntchito kwa mabuleki.
Ndalama Zotsika Zogwirira Ntchito ndi Kukonza
Pogwiritsa ntchitozipangizo zopepuka za ulusi wa kaboniNdipo ukadaulo watsopano, kusowa kwa mawilo ndi njanji kwa sitima za metro za ulusi wa kaboni kumachepa kwambiri, zomwe zimachepetsa kwambiri kukonza magalimoto ndi njanji. Nthawi yomweyo, pogwiritsa ntchito ukadaulo wa digito, nsanja yanzeru yogwirira ntchito ndi kukonza sitima za ulusi wa kaboni ya SmartCare yazindikira kudzizindikira ndi kudzizindikira chitetezo, thanzi la kapangidwe kake ndi magwiridwe antchito a galimoto yonse, kukonza magwiridwe antchito ndi kukonza, ndikuchepetsa mtengo wogwirira ntchito ndi kukonza. Mtengo wonse wokonza sitima wachepetsedwa ndi 22%.
Mu gawo la ukadaulo wa ulusi wa kaboni pamagalimoto a sitima, CRRC Sifang Co., Ltd, pogwiritsa ntchito mphamvu zake zamafakitale, yamanga nsanja yonse ya R&D, kupanga ndi kutsimikizira kudzera mu zaka zoposa 10 za kusonkhanitsa R&D ndi kupanga zinthu zatsopano mogwirizana za "kugwiritsa ntchito mafakitale-yunivesite-kafukufuku-kafukufuku", ndikupanga luso lonse laukadaulo kuchokera kuulusi wa kabonikapangidwe ka kapangidwe kake ndi kafukufuku ndi chitukuko cha kapangidwe kake, kupanga zinthu, kuyerekezera, kuyesa, kutsimikizira khalidwe, ndi zina zotero, ndikupereka yankho limodzi lokha la moyo wonse wa galimoto. Perekani yankho limodzi lokha la moyo wonse.
Pakadali pano,ulusi wa kaboniSitima yapansi panthaka yamaliza mayeso a mtundu wa fakitale. Malinga ndi dongosololi, idzayikidwa mu ntchito yowonetsera okwera ku Qingdao Metro Line 1 chaka chino.
Pakadali pano, pankhani yoyendetsa sitima zapamtunda ku China, momwe mungachepetsere kugwiritsa ntchito mphamvu, kuchepetsa mpweya woipa wa kaboni, ndikupanga sitima yobiriwira yapamtunda yogwira ntchito bwino komanso yopanda mpweya woipa ndiye chinthu chofunikira kwambiri pakukula kwa makampaniwa. Izi zikupangitsa kuti pakhale kufunikira kwakukulu kwa ukadaulo wopepuka wa magalimoto a sitima.
Kuyamba kwa malondaulusi wa kaboniSitima yapansi panthaka, kulimbikitsa kapangidwe ka magalimoto apansi panthaka kuyambira chitsulo, aluminiyamu ndi zipangizo zina zachikhalidwe zachitsulo mpaka ku ulusi wa kaboni, kuswa malire a kuchepetsa kulemera kwa kapangidwe kazinthu zachitsulo, kuti akwaniritse kukweza kwatsopano kwa ukadaulo wopepuka wa sitima yapansi panthaka yaku China, kudzalimbikitsa kusintha kwa zoyendera za sitima zapamtunda za ku China zobiriwira komanso zotsika ndi mpweya, kuthandiza makampani a sitima zapamtunda za ku China kukwaniritsa "kawiri-kawiri". Idzagwira ntchito yofunika kwambiri pakulimbikitsa kusintha kobiriwira ndi kotsika ndi mpweya kwa zoyendera za sitima zapamtunda za ku China komanso kuthandiza makampani a sitima zapamtunda za ku mizinda kukwaniritsa cholinga cha "kawiri-kawiri".
