achitsulo, kufunikira kwa kupatulira mbale yachitsulo. Pomwe mapepala achitsulo wamba nthawi zambiri amakhala pakati pa 0.7 ndi 0.75mm wandiweyani, mapepala amphamvu kwambiri masiku ano amangokhala 0.65mm kapena kuonda, ndipo bonati ya opel seferli yatsopano ndi 0.6mm wandiweyani.

Malinga ndi wang li, “ngati mphamvu yokoka yeniyeni ya chitsulo siinasinthidwe, kulemera kwake kungachepetsedwe kukhala kochepa, koma kachulukidweko kakhoza kusinthidwa. Tsopano tili ndi lingaliro latsopano loti tichite, lomwe ndilo kusintha kachulukidwe kachitsulo.Ubwino wa aluminiyamu ndi kuchepa kochepa, mpikisano pamlingo winawake ndingagwiritse ntchito ubwino wanu kuti musinthe kachulukidwe kanga.Tinakweza modulus yotanuka yachitsulo. , ndipo tsopano ili mu labu.Mfundo imodzi yomwe ndikufuna kupanga ndi yakuti chifukwa zitsulo zokha zimakhalabe zosasinthika pamaziko a mafakitale omwe alipo, pali malo ambiri opangira zatsopano. Kuchokera pamalingaliro awa, chitsulo chikadali ndi mphamvu zina, komanso gawo lake la msika.Ngati galimotoyo ikugulitsa ndalama zoposa 200,000 yuan, idzagwiritsa ntchito zipangizo zambiri. Ngati galimotoyo ikugulitsidwa yuan 100,000, idzagwiritsabe ntchito zitsulo.

Koma vuto la mtengo limakhalanso zinthu zina kuti zilowe m'malo mwa chitsulo cholimba chachitsulo. Shu-ming Chen adati, "panthawi yowunikira magalimoto, ngakhale tsopano aliyense akuchita zinthu zopepuka, monga aluminium alloy, magnesium alloy ndi zina. opepuka gulu zipangizo, mkulu mphamvu zitsulo kapena mu udindo waukulu thupi, koma ine ndikuganiza zinthu zazikulu ndi mtengo, ine ndikukhulupirira kuti ngati mtengo wa mpweya CHIKWANGWANI, mpweya CHIKWANGWANI m'malo mwina, sikutheka, chinsinsi tsopano mtengo ndi. chokwera kwambiri, chitsulo pakali pano chilinso ndi phindu lalikulu kwambiri la ndalama.”

Kuphatikiza pa mtengo, mkati mwa mphamvu zokwaniritsa zofunikira, njira yabwino komanso yosavuta yopangira imakhalanso chifukwa chomwe chitsulo chimakhala chovuta kusinthidwa. osati kwambiri. 1000 mpa ndi zokwanira.Mkulu mphamvu zitsulo tsopano makamaka carbon kulimbitsa, ambiri achita 2200 mpa, koma pamwamba 2200 mpa, adzatulutsa masinthidwe, kapena 2200-2500 mpa carbon kulimbitsa kwenikweni zosatheka.”Ndikukhulupirira chitsulo ichi ndithudi adzakhala ndi zipangizo zina m'malo carbon, mphamvu adzakhala apamwamba ndi apamwamba, koma si ntchito m'galimoto, zikhoza kugwiritsidwa ntchito m'madera ena amphamvu kwambiri. Pakuti magalimoto, tili ndi kusankha lonse zitsulo pansi 1000 mpa, otsika mtengo ndi njira yabwino kwambiri yopangira, kotero zidzakhala zovuta kusintha zitsulo m'dziko lathu kwakanthawi. "

Ndipo kuchokera kuzinthu zamapangidwe azitsulo zokha, zimakhala ndi kukonza bwino.Zhu qiang adanena kuti chitsulo chokha chokhala ndi kusintha kwa gawo chimakhala ndi ubwino wina muzinthu zina. Zitha kukonzedwa mosavuta, zomwe zimakhala zovuta kwa composites kapena aluminiyamu.Mwachitsanzo, aluminium alloy composite material, ngati dzenje lathyoka, kukonzanso kwakukulu ndi gawo lonse la m'malo, mtengo wake ndi wokwera, uku ndiko kufooka kwa aluminiyamu yokha poyerekeza ndi chitsulo.

Aluminiyamu alloy

nthawi yachitukuko yomwe idakumana ndi Nkhandwe pambuyo pa nyalugwe

Ziwerengero zikuwonetsa kuti pamafunika ma kilogalamu 725 achitsulo ndi chitsulo chosungunula ndi ma kilogalamu 350 azitsulo zosindikizidwa kuti apange galimoto yapakatikati. Mosiyana ndi izi, kulemera kwa aluminiyamu mugalimoto yaku Europe kudakwera kuchokera ku 50kg mu 1990 mpaka 131.5kg mu 2005, ndi ambiri akadali ntchito injini internals ndi midadada yamphamvu ndi rise.Aluminiyamu ndi otchuka m'magalimoto chifukwa ndi zosakwana theka la kulemera kwa chitsulo, zinthu ntchito kupanga zitsulo, ndipo ali ndi kukana dzimbiri bwino kuposa chitsulo.Pakali pano, ntchito zotayidwa aloyi kuti thupi la chitsanzo wakhala kwambiri.Kuyambira kubadwa kwake mu 1994, A8 Audi watengera zonse zotayidwa danga chimango dongosolo thupi, ndi Model S anayamba ndi chopangidwa ndi tesla. imatenganso thupi lonse la aluminiyamu. Pambuyo pa mzere wonse wa aluminiyumu yopanga chery jaguar land rover ku changshu, chigawo cha Jiangsu chinapangidwa,galimoto yoyamba yoweta, jaguar XFL aluminium alloy alloy application rate inafika pa 75%.The nobelis RC5754 mkulu-mphamvu zotayidwa aloyi ntchito mbali zambiri za thupi la jaguar XFL ali ndi zokolola za 105-145 Mpa, kumakoka mphamvu 220 Mpa. , ndi ntchito yabwino mu mphamvu, kukana dzimbiri, kugwirizanitsa ndi kuumba."Tsopano aluminium yowonjezereka imagwiritsidwa ntchito pamagalimoto, makamaka pazigawo za chassis, kuwonjezera pa thupi, tsopano magalimoto ambiri akupitiriza kuyenda pamsewu uwu. . "Zhang haitao, wofufuza pa yunivesite ya soochow, anati, "N'chifukwa chiyani mumagwiritsa ntchito mafelemu a aluminiyamu? ndizovuta kwambiri, ndipo kupindika kwa aluminiyumu ndi kuuma kwa torsion kuli bwino kuposa chitsulo.

Kuphatikiza apo, aluminiyamu imakhala ndi kukonzanso bwino kwazinthu komanso moyo wautali kuposa chitsulo. Zhu Qiang adati, "kutayika kwa aluminiyumu yobwezeretsanso ndi 5 mpaka 10 peresenti. Ngati chitsulo chachita dzimbiri, n’kovuta kwambiri kuchichira. Aluminiyamu aloyi ndi ubwino m'kupita kwa nthawi.Ngati mawilo ndi zotayidwa, tsopano tili ndi mgwirizano kuti zitsulo zotayidwa aloyi mawilo ayenera kukhala bwino kuposa zitsulo, chifukwa zitsulo n'zosavuta kukhudza dzimbiri, zitsulo zotayidwa aloyi scraping zilibe kanthu, ntchito zitsulo palibe. kufananiza, magwiridwe antchito a aluminiyamu aloyi pankhaniyi ali ndi mwayi wapadera." Kuphatikiza apo, moyo wautali ndi wofunikiranso pamakampani opanga magalimoto, ndipo chilichonse chiyenera kupangidwa poganizira za moyo wautali. Aluminium ilinso ndi mwayi pankhaniyi. "

Zhu qiang adanenanso kuti mapangidwe a aluminiyamu alloy ndi ovuta, momwe angagwiritsire ntchito gululi ndi vuto. atapatukana, pamafunika khama lalikulu kuti alumikizane, ndipo pamafunika khama lalikulu kuti awalekanitse. Kumbali imodzi, kuchira bwino sikuli kwakukulu, ndipo kumbali ina, sikophweka kuyendetsa.Kuonjezera apo, pali zinthu zambiri zomwe zimakhudzidwa ndi kubwezeretsanso aluminiyamu, monga kuchepetsa kugwiritsidwa ntchito, kukonzanso bwino kwa aluminiyamu kungagwiritsidwe ntchito. kupanga chinthu chosafunikira, zomwe zikadakhala zabwino zimatha kukhala zotsika mtengo. ”

Pankhani ya kutopa kwa zida, aluminiyamu ndi yowopsa kwambiri kuposa chitsulo, ndipo kukonza kumakhala kochepa. Aluminiyamu makutidwe ndi okosijeni mphamvu ndi amphamvu kwambiri, zolakwika izi zimakhudza kwambiri ntchito kutopa kwa zigawo zikuluzikulu, zosavuta kupita molakwika.Chitsulo si oxidize kwambiri ndipo zofooka zake zimakhala ndi zotsatira zochepa kwambiri pa kutopa ntchito."Zhu qiang anati, "kokha ndi forging sangakhale zigawo zikuluzikulu, forging ayenera kukonzedwa, apo ayi sangathe kukumana ndi zosowa za structural design.Nthawi zambiri, pali mitundu iwiri ya forging, mwina kusiya kukhathamiritsa structural kapena reprocessing. Komabe, pamwamba pa aloyi ya aluminiyamu itawonongeka, ntchito ya kutopa idzachepa, ndipo mtengo udzakweranso.Awa ndi mavuto omwe zitsulo za aluminiyamu ziyenera kuthana nazo, ndipo n'zotheka kusintha zitsulo pambuyo pothetsa mavutowa.

Mu galimoto galimoto zitsulo zotayidwa m'malo zitsulo, koma m'zaka zaposachedwapa ndi chitukuko cha luso zitsulo, galimotoyo zitsulo wayambitsa njira zatsopano. Zhu qiang anati, "Tsopano galimotoyo ndi zitsulo, tapanga luso angapo, mmodzi ndi mkono, ". ife tsopano ku 780 mpa tsopano titha kuchita mkono wa triangle wachitsulo, ndi wolemera kwambiri kuposa 10 peresenti kuposa aluminiyamu, mtengo wotsika kwambiri. Palinso kugwirizana pakati pa mawilo awiri omwe ndi olemera kwambiri, ndipo tsopano tapanga teknoloji yatsopano yomwe imachepetsa kulemera kwake ndi 40 peresenti ndikuthetsa vuto la dzimbiri pogwiritsa ntchito zokutira, ndi zitsuloTsopano zitsulo ndi aluminiyamu zikupikisana kuti zilimbikitsane, kotero pali njira zambiri zamakampani opanga magalimoto, motero chitukuko. "

Ndipotu panopa magalimoto zotayidwa walowa siteji pamaso pa Wolf pambuyo nyalugwe.Opanga kale zitsulo kupyolera mosalekeza kusintha kwa ntchito, tsopano zitsulo popanda faifi tambala akhoza kukwaniritsa dzimbiri, pamene otsiriza magnesium aloyi, mpweya CHIKWANGWANI ndi zipangizo zina ndi mtengo wotsika. ndi ntchito bwino, apanga zimakhudza pa zotayidwa market.Zhu qiang ananena, "zotayidwa aloyi kuchita bwino akhoza kukhala mofulumira chitukuko, chifukwa zitsulo wakhala akuchita kwa zaka zambiri m'malo zovuta, zotayidwa ayenera kukhala mafakitale monga posachedwa, sizingasinthidwe mosavuta pambuyo pake, zovuta zamakono zamagalimoto za aluminiyamu ndi mwayi ulipo.Chitsulo - aluminium hybrid thupi kapangidwe ndi kachitidwe

Pakadali pano, akatswiri opanga magalimoto ochulukirachulukira amalabadira kwambiri kugwiritsa ntchito kosakanizidwa kwazinthu zopepuka. kafukufuku wawo ndi chitukuko cholinga si pa chiŵerengero enieni a galimoto zitsulo ndi aluminiyamu, komanso mmene kusakaniza zipangizo zosiyanasiyana molondola.Chaka chatha pa Frankfurt galimoto chionetserocho kuwonekera koyamba kugulu pa latsopano audi A8 wakhala wa Audi a zotayidwa danga chimango mtundu onse. thupi kapangidwe luso luso ndi Mokweza, anasiya Audi wakhala kunyadira thupi lonse zotayidwa, zotayidwa aloyi otsetsereka 58%, kuwonjezera pa kudziwika, mu thupi zinthu anawonjezera zipangizo gulu, thupi pafupifupi 51 kilogalamu. cholemera kuposa chitsanzo cha ndalama, ndi mitundu ya ndalama A8 ya 236 kg "kulemera kosagwirizana ndi 282 kg.

M'badwo watsopano wa Audi A8 umatenga aloyi ya aluminiyamu kuti ipange mawonekedwe onse a thupi. Kuonetsetsa mphamvu structural, zotayidwa zotayidwa ntchito zimfundo kiyi ndi pepala zitsulo mbali ntchito pa thupi pamwamba.Mu kanyumba khola dongosolo la thupi, ambiri otentha kupanga wapamwamba mkulu mphamvu aloyi zitsulo, kutali kuposa panopa. A8 mkulu mphamvu zitsulo pokhapokha ntchito B ndime, mkulu mphamvu zitsulo zakuthupi ndi zaka 20 zapitazo poyerekeza ndi chitsulo, stiffness kuchuluka nthawi 5, kulemera kuchepetsedwa ndi 40%. Magnesium aloyi ndi anawonjezera dongosolo thupi, ndi CFRP mpweya CHIKWANGWANI zinthu zophatikizana zimagwiritsidwa ntchito kumbuyo kwa galimoto, zomwe zimachepetsa kulemera kwa thupi kuchokera kuzinthu monga gulu lakumbuyo.

"M'tsogolomu, aluminiyumu idzagwiritsidwa ntchito kwambiri m'galimoto yonse ya galimoto, ndipo padzakhala matupi ambiri osakanizidwa. Mwachitsanzo, thupi la aluminiyamu la A8 A8 limayambanso kupanga matupi osakanizidwa, ndipo tsopano makampani ambiri apagalimoto apanyumba akutsatira. yachitsulo ndi thupi lapansi limapangidwa ndi aluminiyamu.Mwachitsanzo, zenera lazenera la galimoto la Beijing limapangidwa ndi chitsulo pamwamba ndi aluminiyumu pansi.Osati chitsulocho ndi choipa, koma ndikuganiza kuti ndizowonjezereka kusakaniza zitsulo ndi aluminiyamu. "Zhang haitao adatero.

Pankhani imeneyi, wang li adanenanso kuti, kumayambiriro kwa zaka za m'ma 1940 pamene panali mpikisano wazitsulo ndi aluminiyamu, patatha zaka zambiri zachitukuko, tsopano zipangizo zamagalimoto zafika pa mgwirizano, ndizo zipangizo zoyenera zomwe zimagwiritsidwa ntchito pamalo abwino. .Ndipo chitsulo chokha chikukula mofulumira, ndi mpikisano ndi mgwirizano.Ndipo mpikisano uwu ndi wopindulitsa kwambiri pa chitukuko cha magalimoto oyendetsa galimoto, chifukwa kukhalapo kwa mpikisano wamakampani oyendetsa galimoto kungakhale ndi zosankha zambiri. Kuyang'ana m'tsogolomu, magalimoto atsopano amphamvu akhoza kukhala apamwamba. zofunika zopepuka.

Njira ya "mitundu yodziyimira payokha iyenera kukhala yopepuka, chitsulo chabwino ndi kuthekera kwake sichikhala chaching'ono, pogwiritsa ntchito malonda ophatikizana omwe ali ndi chitsulo champhamvu kwambiri ndipo n'zosavuta kukwaniritsa 10% ya kuchepa kwa thupi loyera, kudzera mwa khama zina galimoto dontho 7% 8% ndi zotheka, chizindikiritsoa gawo la umisiri wapamwamba akhoza kukhala ndi thupi popanda kusintha kupitirira 10%.” “Ndi matekinoloje ena atsopano ndi njira, kuonda kopitirira 20 peresenti kungathe kupezedwa. Tapenda zitsanzo zambiri za mtundu wathu, ndi kuthekera akadali wamkulu. Mpata ndi chilimbikitso chathu
