Kwimveliso yeenqwelo moya—apho ukunyamezelana kulinganiswa kwii-microns kwaye impumelelo yomsebenzi ixhomekeke ekuphindaphindweni kwinqanaba le-nanometer—isiseko sayo yonke inkqubo yokuhlolwa okubalulekileyo okanye yokuhlanganisa kufuneka ingashukumi, ingaguquki, kwaye ingangeni bushushu. Yiyo loo nto abahlanganisi bezinto eziphambili zeenqwelo moya bexhomekeke kakhulu kubungakanani obukhulu.iziseko zegranitekwizikhululo zokulungelelanisa iinjini, izixhobo zokuvavanya umthwalo wesathelayithi, kunye neeseli zemetrology zephiko.
Kwi-zhhimg, asiboneleli nje kuphela ngegranite—siyila uzinzo olubalulekileyo kumsebenzi wethu kwiikali ezimbalwa ezinokulingana.
Kutheni iGranite Ingathathelwa Indawo kwiMetrology yeAerospace
Nangona izinto ezidityanisiweyo kunye neeseramikhi zifumana ukubambelela kwizakhiwo ezikhaphukhaphu, igranite yendalo ihlala iyinto engathandabuzekiyo ekhethwayo kumaqonga okubhekisa azinzileyo kakhulu kwimisebenzi yeenqwelo moya ebiza kakhulu. Iingenelo zayo zibalulekile:
- Ukuqhekeka okuphantse kube yi-zero phantsi komthwalo: Igcina ithambile amashumi eminyaka, nokuba iphantsi kweetoni ezininzi
- Ukuzihlukanisa kokungcangcazela kwangaphakathi: Umthamo wokufuma ungaphezulu nge-3–5× kunentsimbi ephosiweyo okanye intsimbi
- Uzinzo lobushushu: CTE ≈ 6.5 ppm/°C kunye ne-hysteresis encinci kwimijikelo yemihla ngemihla
- Ayisebenzisi magnethi kwaye ayisebenzisi magnethi: Ikhuselekile kwii-avionics ezinobuthathaka kunye novavanyo lokuthwala magnethi
Kwiindawo zokucoca ezidityanisiweyo ngesathelayithi okanye iiholo zokugqibela zendibano ye-jet engine—apho ukungcangcazela komhlaba okuvela kwi-HVAC, ii-cranes, okanye iindlela zeenqwelomoya ezikufutshane kusongela ukuthembeka komlinganiselo—i-granite ayinyanzelekanga. Kubalulekile.
Ukutyhala Imida: Amandla Okuchaneka Kakhulu Ka-zhhimg
Ababoneleli abaninzi bagqiba umlinganiselo wegranite yabo kwi-3m × 2m. Kwi-zhhimg, sihlala sihambisa iziseko zegranite ezizi-monolithic ukuya kuthi ga kwi-9m × 4m × 800mm, ezenziwe ngomatshini ukuya kuthi ga kwi-Grade 00 flatness (≤ 2 + L/1000 µm) kwaye ziqinisekiswe yi-National Institute of Metrology yaseTshayina.
Iiprojekthi zamva nje ziquka:
- Isiseko segranite esibude buziimitha eziyi-7.8 senkqubo yokulungelelanisa injini yeenqwelo-moya zorhwebo, esineendawo ze-T ezidityanisiweyo, iindawo zokumisa umhlaba ezifakwe ngaphakathi, kunye neendlwana zokulandelela i-laser
- Iqonga lesiqithi esineziqithi ezimbini elinobude obuyi-6m × 3.5m lesixhobo sokuvavanya ulwakhiwo lwesathelayithi esijikeleza umhlaba ophantsi, esinomgangatho ohambelana ne-vacuum kunye neendawo zokudibanisa ze-kinematic
- Iziqithi zegranite ezizimeleyo ezenziwe ngokwezifiso ezishukumayo zifakwe ngqo kumgangatho wefektri—ngaphandle kwee-piers zekhonkrithi—kusetyenziswa izixhobo zethu zokuthintela ukuxinana ezizimeleyo
Zonke izinto ezinkulu zifumana uhlalutyo lwe-3D finite element (FEA) ngexesha loyilo ukuze kuphuculwe i-ribbing, iindawo zokuxhasa, kunye nee-modal frequency—ukuqinisekisa ukuba i-first-mode resonance ihlala ingaphezulu kwe-120 Hz, icocekile kwiibhendi zengxolo zemizi-mveliso eziqhelekileyo.
Ukuzihlukanisa nokungcangcazela: Yakhelwe ngaphakathi, Ayinabholiti
Ukwahlulwa kokungcangcazela kwenyani kuqala kwinqanaba lezinto—kodwa i-zhhimg idlulela ngaphaya koko. Iziseko zethu zodidi lweenqwelo-moya ziyadibana:
- Izidambisi zobunzima ezilungisiweyo ukuze kuncitshiswe amaza ajolisiweyo
- Umgangatho ojikelezayo oneerabha zendalo okanye ii-air-spring zokwahlula (ukhetho)
- Izitulo zesensor ezikwiqonga ukuze zijongwe okusingqongileyo ngexesha langempela (ubushushu, ukuthambeka, ukungcangcazela)
Le ndlela ipheleleyo iqinisekisa ukuba nokuba ulungisa i-rotor ye-turbofan ye-5-ton okanye i-calibrating star tracker optics, isiseko sakho sokulinganisa asiphazamiseki.
Inzuzo ye-zhhimg: Ukuchaneka kwiSikali, Ngaphandle kokuHlukana
Sisebenza kwisakhiwo sethu sama-200,000㎡ eShandong—esineendawo zokulungisa ezilawulwa yimozulu (20±0.3°C), ii-5-axis CNC bridge grinders, kunye neelebhu zemetrology zangaphakathi—sidibanisa ukukhethwa kwamatye obugcisa kunye nokusebenza kwemizi-mveliso.
Ibhloko nganye yeJinan Black granite igcinwa iminyaka eyi-≥3 ngaphambi kokuba isetyenzwe, nto leyo eqinisekisa ukukhululeka koxinzelelo lwangaphakathi. Isiqinisekiso sokugqibela siquka:
- Iimephu zokuthamba kwe-laser interferometer
- Iingxelo zefrikhwensi yesandi
- Ukulinganiswa okulandelekayo ngokwe-ASME B89.3.7 kunye ne-JJG 117-2013
Kwii-OEM zeenqwelo-moya kunye neearhente zasesibhakabhakeni, oku akupheleli nje ekuthengeni—kukunciphisa umngcipheko.
Malunga ne-zhhimg
I-zhhimg yinkokheli yehlabathi kwiziseko ezinkulu zegranite kumacandelo anzima kakhulu—ingakumbi i-aerospace, ukhuselo, kunye neenkqubo zesithuba.
