Kwihlabathi elichanekileyo kakhulu lemveliso yanamhlanje, apho izinto zeenqwelo moya, iinjini zaselwandle, kunye neeturbines zamandla amakhulu zichaza imida yobuchule bomntu, isiseko solawulo lomgangatho sihlala sifumaneka kwinto elula ngokukhohlisayo: iqonga lesinyithi elinzima. Ngelixa iilaser zobuchwepheshe obuphezulu kunye neenkqubo zokuskena zedijithali zihlala zibamba ukukhanya, ezi ndawo zinkulu, ezizinzileyo zihlala zisisiseko esithuleyo, esibalulekileyo sobunjineli obukhulu. Njengoko amashishini etyhalela phambili ekunyamezeleni okuqinileyo kunye nezikali ezinkulu zomzimba, ukuqonda indima ebalulekileyo yala maqonga kubalulekile kuye nawuphi na unjineli ogxile ekugqibeleleni kwesakhiwo sexesha elide kunye nokuchaneka kokulinganisa.
Isiseko sokuchaneka kwiindawo ezinkulu
Iqonga lesinyithi esinzima, elidla ngokubizwa ngokuba yipleyiti yomphezulu okanye itafile yokumakisha kwiifomathi ezinkulu, aliyonto nje yesinyithi esinzima. Liqonga lesalathiso elinobunjineli obuphezulu. Kubunjineli obukhulu, umceli mngeni ophambili asikokulinganisa nje inxalenye, kodwa kukuqinisekisa ukuba umlinganiselo uthathwa ngokuchasene "nenqaku le-zero" elithe tyaba, elimelana nokungcangcazela, nelizinzileyo kubushushu. Xa usebenza ne-crankshaft yenqanawa okanye indlu ye-wind turbine, nokuba ukuphambuka okuncinci kwisiseko kunokukhokelela kwiimpazamo ezinkulu zokulungelelaniswa kwiimitha ezininzi zobude becandelo.
Ukukhetha isinyithi esixonxiweyo—ingakumbi isinyithi esingwevu esikumgangatho ophezulu okanye i-HT200-300—kwenziwa ngabom. Ngokungafaniyo nentsimbi, enokuba nengxaki yoxinzelelo lwangaphakathi kunye nokwanda okukhulu kobushushu, isinyithi esixonxiweyo sidlula kwinkqubo yendalo okanye yokwenziwa “yokwaluphala”. Esi sinongo sivumela ulwakhiwo lwangaphakathi lwekristale ukuba luhlale, siqinisekisa ukuba iqonga aligobi okanye “lihambe” ngokuhamba kwexesha. Olu zinzo yingakho, nangona kwixesha le-carbon fiber kunye nee-composites, isixhobo sokuhlola esisisiseko se-turbine ye-multi-dollar sihlala sibhloko yesinyithi esixonxiweyo ngononophelo.
Kutheni iCast Iron ilawula uBunjineli boMhlaba
Umntu angazibuza ukuba kutheni ubunjineli obunzima bungazange butshintshele ngokupheleleyo kwi-granite, into eqhelekileyo kwiindawo ezincinci zelebhu. Impendulo ikukufuna izinto ezisetyenziswa ngoomatshini kwiindawo ezinkulu zokusebenza. Ubunjineli obunzima bubandakanya iindawo ezinobunzima obungamashumi eetoni. Amaqonga esinyithi anika amandla aphezulu okuthwala umthwalo kwaye, okubaluleke kakhulu, amandla okwenziwa ngomatshini ngee-T-slots, imingxunya, kunye neendawo zokufaka.
Ipleyiti yegranite iyaphuka; phosa ibhloko yenjini ye-ten-ton kuyo, kwaye inokuqhekeka. Ngokwahlukileyo koko, iqonga lesinyithi eliphoswe lithambile kwaye liqinile. Ngaphezu koko, isinyithi esiphoswe sineempawu ezizodwa zokungcangcazela. Kwimeko-bume exakekileyo yefektri apho oomatshini abanzima benza ukungcangcazela komgangatho rhoqo, isakhiwo esixineneyo semolekyuli yeqonga lesinyithi esiphoswe sisebenza njenge-buffer yendalo, sifunxa ii-micro-vibrations ebezinokuphazamisana nezixhobo ze-metrology ezinobuthathaka ezifana noomatshini bokulinganisa (ii-CMM) okanye amanqanaba e-elektroniki.
Ubugcisa bokukrwela kunye nejometri yomphezulu
Umphezulu weqonga lokuhlola elikumgangatho ophezulu awufane "ube bushelelezi" ngendlela isibuko esinjalo ngayo. Endaweni yoko, unesiphelo esibonakalayo "esikrwelwe". Le nkqubo yesandla okanye ezenzekelayo ibandakanya ukususa amabala aphezulu ukwenza umphezulu othe tyaba ngaphakathi kwee-microns. Nangona kunjalo, ubume obuvelayo bunceda ngokwenene kwizicelo zobunjineli ezisebenzayo. Iintlambo ezincinci kumphezulu okrwelwe zithintela "ukubhidlika" - isiphumo se-vacuum apho iigeyiji ezithe tyaba zinamathela kwipleyiti - kwaye zivumela ifilimu encinci yeoyile ukukhusela umphezulu ekugqwaleni ngelixa zigcina ukuchaneka kwezixhobo zokulinganisa ezityibilikayo kuyo.
Kwizicelo ezinkulu, la maqonga adla ngokuba ziimodyuli. Iipleyiti ezininzi ezinzima ziyadityaniswa kwaye zilinganiswe njengeyunithi enye ukwenza umgangatho wokuhlola onokufikelela kwiimitha ezingamashumi amathathu okanye amashumi amane. Oku kuvumela iinjineli ukuba zihlanganise kwaye zihlole yonke i-chassis yesithuthi okanye iindawo ze-fuselage kwiplani enye, edibeneyo.
Ukugcinwa kunye nobude bexesha: Inkulungwane yokuchaneka
Esinye sezizathu zokuba ezi zixhobo zixatyiswe kakhulu kwiindaba zoshishino nakwimijikelo yokuthengwa kwempahla bubomi bazo obumangalisayo. Iqonga lesinyithi eligcinwe kakuhle linokusebenzela inkampani yobunjineli iminyaka engaphezu kwamashumi amahlanu. Nangona kunjalo, ukugcinwa kwalo ngumsebenzi onzima. Ngenxa yokuba isinyithi esityhidiweyo sichaphazeleka lula kukubola, ulawulo lokufuma kunye nokuthambisa rhoqo kubaluleke kakhulu.
Ngaphezu koko, "ukulinganisa" kuyimfuneko ephindaphindayo. Kwiminyaka emininzi yokusetyenziswa, ukutyibilika okukhulu kwamalungu kunokuwohloka kwiindawo ezithile zepleyiti. Iingcali ezizodwa zisebenzisa amanqanaba e-elektroniki kunye ne-laser interferometers ukumakisha "i-topography" yeqonga, zichonga naziphi na izinto eziphambukayo kwi-absolute plane. Ukuba ipleyiti ayinyamezelani, iyakhuhla kwakhona okanye ibuyele kwimimiselo yayo yokuqala. Olu hlobo "oluvuselelekayo" lwenza ukuba ibe lutyalo-mali oluzinzileyo nolunexabiso eliphantsi kunezisombululo ezininzi zedijithali kuphela eziphelelwa lixesha kwiminyaka elishumi.
Uzinzo lobushushu: Umngeni ofihlakeleyo
Kwinjineli enkulu, utshaba lokuchaneka bubushushu. Ukutshintsha kobushushu obuzii-degrees ezimbalwa kunokubangela ukuba icandelo lentsimbi eliziimitha ezintlanu lande ngee-microns ezininzi. Amaqonga esinyithi anzima anobunzima obuphezulu bobushushu, oko kuthetha ukuba atshintsha ubushushu kancinci kakhulu. Olu xinzelelo lubonelela "nge-thermal buffer," enika abahloli indawo ehambelanayo nokuba ubushushu beworkshop buyatshintshatshintsha ngexesha lokutshintsha komsebenzi.
Izakhiwo zobunjineli zanamhlanje zihlala zifakela la maqonga kwiziseko zekhonkrithi ezinzulu nezizimeleyo ukuze zikwazi ukuzidibanisa nobushushu besakhiwo kunye neentshukumo zesakhiwo. Eli nqanaba lolawulo lokusingqongileyo livumela ukuchaneka kwe-sub-millimeter efunekayo ekuhlanganiseni izixhobo zesitimela esinesantya esiphezulu okanye ii-bulkheads zeenqwelo-moya.
Ukudibana Kwesiko Neteknoloji
Nangona la maqonga ngokwawo engokwesiko, ukusetyenziswa kwawo kudityaniswa ngakumbi netekhnoloji yenkulungwane yama-21. Namhlanje, iqonga lesinyithi esinzima lidla ngokuba "liqonga" leengalo zeCMM eziphathekayo, ii-laser trackers, kunye nee-scanner ze-3D. Ngokubeka icandelo kumphezulu othe tyaba oqinisekisiweyo, isoftware eqhuba ezi zixhobo zedijithali inokuseka inkqubo yokulungelelanisa echanekileyo ngakumbi.
Umzekelo, xa kuhlolwa i-casing enkulu yepompo, iqonga le-cast iron libonelela "ngedatha ephambili." I-laser tracker emva koko imaphu yeempawu ze-casing ngokumalunga nepleyiti. Ngaphandle kokuzinza ngokomzimba kwesiseko se-cast iron, imilinganiselo yedijithali ibiya "kushukuma," njengoko ii-sensors bezingayi kuba nendawo ezinzileyo nengashukumiyo yokujonga.
Isiphelo: Isiseko soMgangatho weShishini
Njengoko sijonge kwikamva lobunjineli obukhulu—nokuba kusekukhiweni kwee-reactor zenyukliya eziguquguqukayo okanye kwisizukulwana esilandelayo seenqanawa zokuhlola ulwandle olunzulu—imfuno yamaqonga esinyithi anzima ayibonisi zimpawu zokuncipha. Amele umanyano olugqibeleleyo lwesayensi yesinyithi kunye nobunjineli boomatshini obusebenzayo.
La maqonga angaphezulu nje kweetafile; abonakalisa ngokwasemzimbeni "u-zero" kwinkqubo ye-XYZ coordinate. Anika ukuzithemba kokuba inxalenye eyenziwe kwenye indawo yehlabathi iya kuhambelana ngokugqibeleleyo nenxalenye eyenziwe kwenye. Kwixesha lotshintsho olukhawulezayo lwedijithali, iqonga lesinyithi esinzima lihlala liyisikhumbuzo esinamandla sokuba ubunjineli obuphezulu busaxhomekeke kwisiseko esiqinileyo, esizinzileyo, nesithe tyaba ngokugqibeleleyo. Nasiphi na isakhiwo esijolise kwincopho yomgangatho wokuvelisa, ezi zixhobo azikho nje ukhetho—ziyimfuneko ebalulekileyo yokuchaneka, ukuthembeka, kunye nempumelelo yexesha elide.
