Aluminium iri kwese kwese kuti ingave yakareruka chimiro kana yakakwira yekupisa uye yemagetsi conductivity inodiwa. Iyo yakajairika sportbike ine aluminum cylinder block, musoro, uye crankcases, pamwe newelded aluminum chassis uye swingarm. Mukati meinjini, yakakosha aluminium application mapistoni ayo, ayo nekuita kupisa zvakanaka anokwanisa kurarama nekusangana netembiricha yekutsva iri kure pamusoro penzvimbo yavo yekunyungudika. Mavhiri, anotonhodza uye marayaireta emafuta, marevheti emaoko nemabhuraketi awo, kumusoro uye (kazhinji) korona dzepazasi dzeforogo, epamusoro forogo machubhu (muUSD maforogo), mabhureki caliper, uye master silinda zvakafanana nealuminium.

Tese takatarisa tichiyemura aruminiyamu chassis ine welds yakafanana neyakawa yakawa stack ye poker chips. Zvimwe zvezvisikisi uye swingarms, zvakadai seaya eAprilia maviri-stroke 250 racers, mabasa akanaka eunyanzvi.

Aluminium inogona kusanganiswa uye kupisa-kupiswa kune masimba makuru kupfuura ayo esimbi yakapfava (60,000 psi tensile), asi akawanda alloys muchina nekukurumidza uye nyore. Aluminium inogona zvakare kukandwa, kufogirwa, kana kuburitswa (ndiwo magadzirirwo anoitwa mamwe matanda epachassis). Aluminium's high heat conductivity inoita kuti welding yayo ide amperage yakawanda, uye simbi inopisa inofanira kuchengetedzwa kubva mumhepo yemhepo neinert-gas shielding (TIG kana heli-arc).

Kunyange zvazvo aruminiyamu inoda huwandu hwakawanda hwemagetsi kuhwina kubva kune yayo bauxite ore, kana yavepo muchimiro chesimbi, inodhura zvishoma kudzoreredza uye haina kurasika kuita ngura, sezvingaitwa simbi.

Vagadziri vekutanga veinjini dzemidhudhudhu vakakurumidza kutora simbi itsva panguva iyoyo yemakrankcase, ayo angadai aifanira kunge ari esimbi yakakandwa inorema zvakapetwa katatu. Aruminiyamu yakachena yakapfava zvikuru-Ndinorangarira kutsamwa kwaamai vangu nekushandisa kwababa vangu 1,100-alloy-double-boiler semusungo wakagadziridzwa weBB: Pazasi payo pakava madhimples akawanda.

Kuwedzera kwesimba resimbi yakapfava nemhangura kwakakurumidza kuwanikwa, uye yakanga iri alloy yakadaro iyo piyona wemotokari WO Bentley akashandisa muhondo yake yeNyika I yokuedza mapiston ealuminium. Mukuyedzwa-kumashure-kumashure kurwisa mapistoni akakandwa ipapo akatonga, Bentley yekutanga-yedza aluminium pistons yakabva yawedzera simba. Vaimhanya zvinotonhorera, vachipisa musanganiswa wemafuta-mhepo yaiuya zvishoma, uye vakachengetedza huwandu hwayo. Nhasi, mapistoni ealuminium anoshandiswa pasi rose mumajini emotokari uye emidhudhudhu.

Kusvika pakuuya kwendege yeBoeing's carbon-fiber reinforced-plastic 787 airliner, chaive chokwadi chendege kuti huremu hwese hwendege hwaive 60 muzana yealuminium. Tichitarisa huremu uye kusimba kwealuminium nesimbi, izvi pakutanga zvinoita sezvisinganzwisisike. Hongu, aruminiyamu inorema 35 muzana chete sesimbi, vhoriyamu yevhoriyamu, asi yakakwirira-yakasimba simbi inokwana katatu kusimba kupfuura yakakwirira-simba aruminiyamu. Wadii kugadzira ndege nesimbi yakatetepa?

Yakasvika pakupokana nekusungwa kwezvimiro zvakaenzana zvealuminium nesimbi. Kana tikatanga nearuminiyamu nesimbi machubhu ehuremu hwakafanana parutsoka, uye tikadzikisa ukobvu hwemadziro, chubhu yesimbi inosunga pekutanga nekuti zvinhu zvayo, zvichingova chikamu chimwe chete muzvitatu pakukora sealuminium, inokwanisa kushomeka kuzvidzora.

Mukati mema1970, ndakashanda nomugadziri wefuremu Frank Camillieri. Pandakamubvunza kuti sei tisina kushandisa tubing yesimbi yakakura-dhayamita yemadziro matete kugadzira mafuremu akareruka, akaomarara, akati, “Paunoita izvozvo, unoona kuti unofanira kuwedzera zvinhu zvakawanda kuzvinhu zvakaita semasimbi einjini. chengetedza kuti dzisatsemuka, kuitira kuti kuchengetedza uremu kunyangarike.

Kawasaki akatanga kutora aluminium swingarms pafekitori yayo MX mabhasikoro mukutanga kwema1970; vamwe vakateverawo. Zvino muna 1980, Yamaha akaisa Kenny Roberts pabhasikoro reGP 500-two-stroke iro furemu yakagadzirwa kubva paskweya-chikamu chakawedzera aruminiyamu chubhu. Kuedza kwakawanda kwekugadzira kwaidiwa, asi pakupedzisira, kushandisa pfungwa dzeinjiniya wekuSpain Antonio Cobas, Yamaha's GP mugwagwa-mujaho mafuremu akashanduka kuita akajairwa makuru mapatya aruminiyamu matanda anhasi.

Zvirokwazvo kune chassis yakabudirira yemamwe marudzi-Ducati's steel-tube "trellis" yeimwe, uye John Britten's "ganda nemapfupa" kabhoni-fiber chassis yekutanga 1990s. Asi mapatya ealuminium beam chassis ave kutonga nhasi. Ndine chivimbo chekuti chassis inoshanda inogona kugadzirwa neplywood yakaumbwa, chero iine mabolting mapoinzi uye yakajairwa kuratidzwa geometry.

Imwe mutsauko wakakosha pakati pesimbi nealuminium ndewekuti simbi ine izvo zvinonzi muganhu wekuneta: nhanho yekushanda yekushushikana pazasi iyo hupenyu hwechikamu hahuna magumo. Mazhinji aruminiyamu alloys haana muganhu wekuneta, ndosaka maaruminiyamu airframe "achirarama" kwenhamba yakarongwa yemaawa ekushandiswa. Pasi pemuganhu uyu, simbi inotikanganwira kudarika kwedu, asi aruminiyamu inoyeuka kutuka kwose nenzira yekusaoneka kwemukati kuneta kukanganisa.

Iyo yakanaka GP chassis ye1990s haingambove hwaro hwekugadzira huwandu. Iyo chassis yaive nezvimedu zvakabatanidzwa pamwechete kubva kumichina, yakatsikirirwa, uye yakakandwa-aluminium zvinhu. Haisi iyo chete yakaoma, asi inoda kuti ese matatu alloys ave anowirirana. Welding inodhura mari uye nguva, kunyangwe ikaitwa nemarobhoti ekugadzira.

Tekinoroji yaita kuti maenjini emazuva ano asingaremekedzi mana uye chassis yekukanda igoneke ndeye yakaderera-turbulence-yekuzadza mold nzira dzisingapinze mafirimu ealuminium oxide anoumba ipapo paaluminum yakanyungudutswa. Mafirimu akadaro anoumba nzvimbo dzeutera musimbi iyo, kare yaida kuti makanda awedzere kukora kuti awane simba rakakwana. Zvikamu zvekukandira kubva kune aya matsva maitiro anogona kuve akaomarara, asi yanhasi aluminium chassis inogona kuunganidzwa ine welds inoverengeka kune rimwe ruoko. Inofungidzirwa kuti nzira nyowani dzekukanda dzinochengetedza makumi matatu kana anopfuura mapaundi ehuremu mumadhudhudhu ekugadzira.

Pamwe chete nemhando dzakasiyana-siyana dzesimbi, aruminiyamu ibhiza rekutanga rebudiriro yemunhu, asi zvinopfuura izvo zvemidhudhudhu yemazuva ano. Inyama yebhasikoro, iri pose pose zvekuti hatimboione kana kubvuma kuti mashandiro emuchina uyu ane chikwereti chakadii kwairi.
