Joalo ka karolo ea mantlha ea koloi ea powertrain le sistimi ea phetiso ea mokelikeli, ho tšepahala ha li-autopipe ho ama ka kotloloho polokeho ea koloi le bophelo ba ts'ebeletso. Ha indasteri ea likoloi ea sejoale-joale e ntse e tsoela pele ho ea ho ts'ebetso e nepahetseng le ho rarahana ho hoholo, tokiso ea liphaephe e fetohile ho tloha phetohong e bonolo ho ea ho projeke e hlophisitsoeng e kopanyang mahlale a mahlale, mechini ea mokelikeli le mahlale a machining a nepahetseng. Sengoliloeng sena se hlalosa ka mokhoa o hlophisehileng mekhoa ea profeshenale le boiphihlelo bo sebetsang ba tokiso ea autopipe ho latela maikutlo a tlhahlobo ea liphoso, mekhoa ea ho lokisa, khetho ea thepa, le taolo ea boleng.
I. Mefuta e Tloaelehileng ea Phoso le Mekhoa ea Tlhahlobo
Ho hloleha ho itseng ha lipompo tsa autopipe ho bonahala e le ho lutla, ho thiba, mapetsong, le ho hloleha ha sehokelo. Lithapo tsa mafura li na le ho lutla ha rabara ka lebaka la-ho lula nako e telele mouoane oa peterole, ha mehala e phahameng-ea khatello ea oli e ka senyeha ka lebaka la ho phatloha ha tšepe ka lebaka la khatello ea maikutlo. Liphaephe tsa tsamaiso e pholileng li atisa ho ba le phello ea throttling e bakoang ke li-depositi tsa sekala, ha melapo ea mariki, ka lebaka la ho fokotseha ha bophara bo ka hare bo bakoang ke ho bola, hangata e lebisa ho tahlehelo ea matla a braking. Theknoloji ea morao-rao ea ho hlahloba e fetisitse mefokolo ea tlhahlobo ea pono ea setso. Li-sensor tsa khatello ea dijithale li ka lemoha ka nepo liphetoho tse fapaneng tsa khatello tse tlase ho 0.1 MPa. Lik'hamera tsa infrared thermal imaging li ka fumana likhaello tsa mocheso libakeng tse patehileng. Li-endoscope tse kopantsoeng le li-tracers tsa fluorescent li ekelitse sekhahla sa ho lemoha li-microcracks ho feta 92%. Tabeng ea tokiso e amang lets'oao la Jeremane, tlhahlobo ea spectrum vibration e atlehile ho fumana mohloli oa ho robeha ha mokhathala peiping ea oli ea alloy alloy e bakoang ke bracket resonance.
II. Ts'ebetsong ea Mekhoa e Khethehileng ea Tokiso
Litharollo tse fapaneng tsa tokiso lia hlokahala bakeng sa mefuta e fapaneng ea liphoso. Bakeng sa liphaephe tsa tšepe tse senyehileng sebakeng sa heno, ka mor'a ho tlosa karolo e senyehileng ka ho itšeha ka plasma, lisebelisoa tse khethehileng tsa ho chesa li sebelisoa ho lokisa manonyeletso a ho qetela, ho etsa bonnete ba hore botenya ba lerako la li-welds tse ncha tse kopantsoeng bo ka hare ho 0.15 mm. Ha ho nkeloa sebaka sa li-hose, torque e boletsoeng ke moetsi (hangata 25-35 N·m) e tlameha ho khomareloa ka thata, 'me sekontiri sa torque se sebelisetsoe ho netefatsa{6}}likhutlo tse peli. Litokiso tsa lipeipi tsa oli tse nang le khatello e phahameng li hloka tlhokomelo e khethehileng taolong ea bohloeki. Tikoloho ea tokiso e lokela ho kopana le litekanyetso tsa bohloeki tsa kamore ea 7 ea ISO 14644-1, 'me ho hloekisoa ha ultrasonic ka tharollo ea joala ea isopropyl ho lokela ho etsoa pele ho kopano. Buka ea tlhokomelo ea k'hamphani e ncha ea koloi e hatisa ka ho khetheha hore ka mor'a ho lokisoa, mela e pholileng e tlameha ho feta tekong ea khatello ka makhetlo a 1.5 khatello ea ho sebetsa (bonyane metsotso e 15), 'me ho theoha ha khatello ha hoa lokela ho feta 3% ea boleng ba pele.
III. Boitsebiso ba Saense le Khetho ea Tšebelisano
Khetho ea thepa ea ho lokisa e ama ka ho toba katleho ea tokiso le bophelo ba tšebeletso. Litiiso tsa Fluororubber (FKM) li khothaletsoa bakeng sa lisebelisoa tsa mafura, kaha li fana ka mocheso o fapaneng oa -20℃ho 200 degrees 'me o khona ho thibela ho ruruha ha mafura a ethanol{6}} a kopantsoeng. Inconel 625 alloy e ratoa bakeng sa-libaka tse phahameng tsa mocheso (joalo ka lithapo tsa turbocharger), kaha e boloka matla a ho thella le ho 850 degrees . Ho theknoloji ea sejoale-joale ea ho lokisa likaroloana, carbon fiber{11}}reinforced epoxy resin e se e sebelitse ka katleho ho lokisa lipeipi tse senyehileng tsa mosi. Ts'ebetso ea eona ea mocheso ke karolo ea borobeli feela ea thepa e tloaelehileng ea asbestos, ha matla a eona a tsitsitseng a feta makhetlo a mararo. Hape ke habohlokoa ho hlokomela hore lisebelisoa tsa welding bakeng sa liphaephe tse fapaneng tsa tšepe li tlameha ho lumellana ka tieo. Ka mohlala, liphaephe tsa alloy alloy li lokela ho sebelisa terata ea ER4043 e nang le welding e sirelelitsoeng ka argon, e nang le motlakase o laoloang ka har'a mefuta ea 120-150A.
IV. Tiisetso ea Boleng le Tlhokomelo e Thibelang
Ho hlokahala-seseteme ea tlhahlobo ea likarolo tse ngata ho netefatsa boleng ba tlhokomelo. Teko ea khatello e lokela ho etsoa ka mokhoa o hlophisitsoeng, ho qala ka tlhahlobo ea pele ea ho lutla ka makhetlo a 1.2 khatello ea ts'ebetso, ebe butle-butle e eketseha ho 90% ea moeli oa khatello ea moralo. Ho kgothaletswa ho bona ho dutla ha hydrogen mass spectrometer bakeng sa ho fumanwa ha dutla, ka tekanyo e tlase e lemohuwang ya ho dutla ho 5 × 10⁻¹² Pa·m³/s. Bakeng sa tlhokomelo e thibelang, ho kgothaletswa hore o lekole seseteme ya ho tsidifatsa pH dikhilomithara tse ding le tse ding tse 20,000 (haholo-holo ka hare ho sebaka sa 7.5-8.5). Ho hlokahala phetoho e felletseng ea sepholi ha conductivity e feta 3000 μS/cm. Ka mor'a ho kenya tšebetsong "-sistimi ea tlhokomelo ea maemo a mararo," sehlopha se seng sa likoloi tsa khoebo se ile sa fokotseha ka 67% ho sekhahla sa ho se sebetse se amanang le lipeipi. Mehato ea mantlha e kenyelletsa tlhahlobo ea khoeli le khoeli ea ho tiea ha clamp, tlhahlobo ea kotara ea libaka tse mahlonoko ho sebelisoa borescope, le phetoho ea selemo le selemo ea litiiso tsohle tsa rabara.
Ka lebaka la ho potlakisa ho kenngoeng ha motlakase oa likoloi, ho lokisa lipeipi tse futhumatsang{0}motlakase oa motlakase o phahameng e se e le sebaka se hlahang. Basebeletsi ba tlhokomelo ha ba hloke ho tseba mekhoa ea khale ea ho lokisa mechine empa hape ba lokela ho tloaelana le-mekhoa ea tšireletso ea motlakase o phahameng (joalo ka ho roala lisebelisoa tsa tšireletso tsa CAT III). Nakong e tlang, lits'ebetso tsa ho bolela esale pele boemo ba liphaephe tse thehiloeng ho theknoloji ea mafahla a dijithale li tla ntlafatsa ho nepahala ha tlhokomelo. Ka ho sebelisa li-algorithms tsa ho ithuta tsa mochini tse hlokomelang khatello ea mokelikeli, mocheso le data ea vibrate ka nako ea 'nete, li ka fana ka temoso ea pele ea ho hloleha ho ka bang teng matsatsi a 14-21 esale pele. Likhamphani tsa tlhokomelo ea litsebi li lokela ho theha liforomo tsa tlhokomelo ea dijithale tse kenyelletsang datha ea lisebelisoa, lilaeborari tsa ts'ebetso ea paramente, le metheo ea tsebo ea linyeoe. Ena ke tsela e ke keng ea qojoa ea nts'etsopele ea ho ntlafatsa boleng ba tlhokomelo le katleho.
