Porsche irimo gukora ubushakashatsi bwikoranabuhanga rya 3D kandi ubu, kunshuro yambere, iyikoresha mubice byimuka cyane nka piston. Biracyari prototype, ariko ibisubizo byambere byibizamini kuri piston yanditse biratanga ikizere.
Ibisubizo byubufatanye bwiterambere hagati ya Porsche, Mahle na Trumpf (batezimbere uburyo bwo gukora no gucapa), kugirango bagerageze iryo koranabuhanga, uruganda rw’Abadage rwateranije izo piston muri flat-esheshatu za "monster" 911 GT2 RS.
Urashobora kwibaza, kuki ucapisha piston?
Piston yahimbwe muri moteri ya 911 GT2 RS yamaze gukoresha tekinoroji yo gukora ihuza urumuri, imbaraga nigihe kirekire. Ibyingenzi byingenzi kugirango uhangane nuburyo bukomeye bwasezeranijwe.
Ariko, birashoboka kujya kure. Icapiro rya 3D cyangwa inyongeramusaruro (kubice) igufasha guhitamo igishushanyo cya piston, cyane cyane kurwego rwimiterere, ugakoresha ibikoresho gusa kandi aho imbaraga zikorera kuri piston. Gukwirakwiza ibintu bidashoboka kuboneka hamwe nuburyo bwa gakondo bwo gukora, gusa birashoboka kuko icapiro rya 3D "rirema" ikintu cyakurikiranye nyuma, bigatuma bishoboka gushakisha uburyo bushya.
Iyandikishe mu kanyamakuru kacu
Igishushanyo mbonera gishobora kuvamo ibinyabuzima byinshi kuruta imiterere ya geometrike isa nkaho ituruka muri kamere, bityo rero igishushanyo mbonera cya bionic.
Mu kurangiza, dufite ibice bifite ubunyangamugayo bukenewe - Porsche ivuga ko piston zacapwe zikomeye kuruta izihimbano - ariko ibikoresho bike bikenewe kugirango ibyo bisubizo bibe byoroshye.
Kugereranya piston yahimbwe (ibumoso) na piston yanditse (iburyo).
10% yoroshye, 300 rpm, 30 hp
Ku bijyanye na pisitori za Porsche zacapwe, iryo koranabuhanga ryabemereye kugabanya ubwinshi bwa 10% ugereranije na piston mpimbano zikoreshwa muri 911 GT2 RS, ariko nk'uko Frank Ickinger wo mu ishami ry’iterambere rya Porsche abitangaza ngo “ibigereranyo byacu birerekana ko hariho ubushobozi bwo kuzigama ibiro bigera kuri 20% ”.
Mu modoka, uburemere, cyangwa se misa, ni umwanzi - ni nako bimeze kuri moteri. Piston nikintu kigenda, gukuraho misa bizana inyungu. Mugihe cyoroheje habaho inertia nkeya, kubwibyo, muburyo, imbaraga nke zizakenerwa kugirango tuyimure.
Igisubizo nuko pistors ya Porsche yacapuye yemerera 911 GT2 RS ya 3.8 biturbo ya flat-itandatu gukora kuri 300 rpm hejuru ya moteri ikora, bikavamo hp 30 hp yingufu nyinshi, cyangwa 730 hp aho kuba cv 700.
Ariko ibyiza ntibirangirana numucyo mwinshi wa piston. Nkuko twigeze kubivuga, icapiro rya 3D ryemerera inzira zidashoboka kugerwaho nuburyo gakondo bwo gukora. Kubijyanye nizi piston zacapwe, gukora layer byemerewe kongeramo umuyoboro ukonje inyuma yimpeta ya piston. Ninkaho umuyoboro ufunze imbere ya piston, hamwe na enterineti ebyiri zinjira gusa nizisohoka kumavuta ya peteroli.
Hamwe nubu buryo bwo gukonjesha byongeye, ubushyuhe bwa piston mugihe ikora bwaragabanutseho hejuru ya 20 ° C mubyukuri aho bikorerwa imitwaro myinshi yubushyuhe. Mugushikira ubushyuhe buke bwo gukora bwa piston, Porsche nayo yashoboye guhuza umuriro, kongera umuvuduko nubushyuhe, bivamo gukora neza. Nkuko Frank Ickinger abivuga:
Ati: "Uru ni urugero rwiza rw'ukuntu moteri yaka igifite ubushobozi bw'ejo hazaza."
Nigute byacapwe piston ya Porsche
Gufatanya na Mahle - yateje imbere kandi ikora piston zihimbano kuri 911 GT2 RS - zabafashaga gukora ifu yumuringa ikora nka "wino" yo gucapa piston. Ifu ikoresha Mahle ya M174 + aluminiyumu, kimwe na piston yahimbwe ya 911 GT2 RS. Rero, ibiranga piston zacapwe biragereranywa nibya piston.
Lazeri ishonga ifu yumuringa, hanyuma, piston ifata ishusho.
Injira Trumpf, wateje imbere umusaruro no gucapa. Icapiro ryinshi rya Trumpf TruPrint 3000 Printer ya 3D ihuza ifu, igipande nyuma, binyuze munzira yitwa LMF, cyangwa laser fusion. Muri ubu buryo, ifu yashongeshejwe nigitereko cya laser gifite uburebure bwa mm 0,02 kugeza kuri mm 0.1, umurongo ku kindi.
Muri iki gihe, ibice 1200 birakenewe bizatwara amasaha 12 yo gucapa.
Imashini icapa ya Trumpf yemerera gucapa piston icyarimwe icyarimwe kandi nyuma yo gusesengura neza piston zacapwe, kubufatanye na Zeiss, hemejwe ko zidatandukanye na piston mpimbano.
Mucapyi ya Trumpf irashobora gucapa piston icyarimwe.
ikizamini, ikizamini
Nyuma yo gushyirwa kuri flat-itandatu ya 911 GT2 RS, igihe kirageze cyo kubagerageza. Hamwe na moteri yashyizwe ku ntebe yikizamini, yashyizwe mu kizamini mu kizamini cyo kwihangana amasaha 200.
Mu bizamini bitandukanye byakozwe, kimwe muri byo cyagereranije isiganwa ry’amasaha 24 ku muvuduko wihuse: “ryagenze” hafi kilometero 6000 z'umuvuduko ugereranije na kilometero 250 / h, ndetse ryigana guhagarara kuri lisansi. Ikindi kizamini cyarimo amasaha 135 kumurimo wuzuye n'amasaha 25 kubiciro bitandukanye.
Ibisubizo by'iki kizamini gikomeye? Ikizamini cyatsinzwe, hamwe na piston zose zacapwe zatsinze ikizamini utiyandikishije muburyo ubwo aribwo bwose.
Tuzabona izo piston zacapwe zigera ku isoko?
Nibyo, tuzareba, ariko nta ngengabihe yihariye. Ubuhanga bwo gucapa 3D bumaze imyaka mike kandi bumaze gukoreshwa cyane mubikorwa byimodoka, ariko ukuri ni uko yashushanyije hejuru yubushobozi bwayo.
Tuzabona piston zacapwe kuri moderi ya Porsche? Birashoboka cyane.
Ubu ni tekinoroji isanzwe muri prototyping. Iragufasha gukora ibice byihariye ndetse ukanashakisha ibintu bitandukanye muburyo bwo gushushanya byihuse utiriwe utezimbere imashini zo kubikora, gufungura isi yose ishoboka.
Porsche isanzwe ikoresha iri koranabuhanga mubindi bice, nko mumarushanwa hamwe na kera. Porsche Classic imaze gukora ibice 20 (muri plastiki, ibyuma nibindi byuma byuma) kugirango bigaragare hifashishijwe imashini ya 3D, bitagikora kandi ubundi ntibishoboka kongera kubyara.
Tuzabona kandi ikoranabuhanga rikoreshwa muburyo budasanzwe cyangwa butanga umusaruro muke, cyangwa no muburyo bwo guhitamo cyangwa kugena - urugero, uyumwaka, intebe yuburyo bwa baquet ukoresheje icapiro rya 3D yabonetse nkuburyo bwa 718 na 911 -, kubera ko ubu bwoko bwinganda buhinduka mubukungu na tekiniki birashimishije.
Porotipire yintebe yingoma ukoresheje icapiro rya 3D
Porsche nayo irimo gukora kugirango ishyire mubikorwa iryo koranabuhanga muburyo bwo gukora cyane, ikintu kizabaho mugihe kirekire. Igihe kingana iki? Nibyo twabajije Frank Ickinger, kandi igisubizo cye, tudashidikanya rwose, "byibuze imyaka 10 (2030)" - tugomba gutegereza, ariko ubushobozi bwo gucapisha 3D kimwe nibishobora kubangamira ntawahakana.
