Utshintsho ekuhlolweni kweBlade ye-Aero-injini: Ukufikelela njani kwi-0.1μ M-inqanaba le-M-level ezintathu-dimensional Contour Measurement kwiiPlatform zeGranite?

Ukuchaneka kweencakuba ze-injini ye-aero inxulumene nokusebenza ngokubanzi komatshini, kwaye umlinganiselo wecontour ye-three-dimensional kwinqanaba le-0.1μm ibe yimfuno engundoqo yokuvelisa. Amaqonga emveli anzima ukuhlangabezana nemigangatho. Iiplatifti zeGranite, ezineenzuzo zazo ezintathu ezinkulu, zibonelela ngenkxaso ethembekileyo yokuchongwa ngokuchanekileyo.

Ukuzinza kwe-thermal kwakha isiseko esichanekileyo. I-coefficient yokwandiswa kwe-thermal ye-granite kuphela (4-8) × 10⁻⁶/℃, engaphezulu kwe-60% ephantsi kuneyentsimbi. Ngaphantsi kokuguquguquka kweqondo lokushisa kwe-± 1℃, utshintsho lobungakanani beqonga le-1 lemitha ubude lingaphantsi kwe-0.008μm, elinokubonelela ngokuqhubekayo kwendawo yokubhekisela kwizixhobo ezifana ne-laser interferometers kunye noomatshini bokulinganisa abathathu, ukuphepha ukuqokelelwa kweempazamo zokulinganisa okubangelwa yi-thermal deformation. Okwangoku, ukuxinana kwayo kufikelela kwi-2.6-2.8g/cm³, amandla ayo acinezelayo adlula i-200MPa, ayigugi, kwaye iqinisekisa ukuba ukuchaneka kuhlala kungatshintshi ngokusetyenziswa kwexesha elide.

Ukumelana nokungcangcazela okugqwesileyo kunye nokwahlulwa kokuphazamiseka kokusingqongileyo. Indibano yocweyo ngeenqwelomoya iyangcangcazela rhoqo. Ubume obukhethekileyo bekristale yegranite yenza umlinganiselo wayo wokudambisa ufikelele kwi-0.05-0.1, eyi-5-10 ngamaxesha esinyithi. Inokuthomalalisa ngaphezulu kwe-90% yamandla okungcangcazela ngaphakathi kwemizuzwana eyi-0.3. Ukuthatha umlinganiselo nge-laser tracker njengomzekelo, xa udibene neqonga legranite, i-laser beam offset inokulawulwa ngaphakathi kwe-± 0.02μm, iphucula kakhulu ukuchaneka komlinganiselo weempazamo zeprofayili ye-blade.

Ukudityaniswa kobuchule bobugcisa obuchanekileyo kunye nobukrelekrele kwandisa ukusebenza kakuhle. Emva kokulungiswa kwe-ultra-precision efana ne-magnetorheological polishing, ukufudumala kweqonga le-granite lifikelela ku-± 0.1μm / m, kunye nobunzima bomhlaba u-Ra ngu-≤0.02μm. Emva kokudibanisa nabalawuli be-nanoscale grating kunye ne-AI algorithms, ukuchaneka kokulinganisa inqaku elilodwa lifikelela kwi-0.05μm, impazamo iyonke iyancitshiswa ibe yi-± 0.1μm, ukufumanisa ukusebenza kakuhle kunyuswe ngama-30%, kwaye izinga lokufumanisa isiphene lifikelela kwi-99.9%.

Amaqonga e-Granite, kunye nokusebenza kwawo okuzinzile nokuthembekileyo, akhusela umlinganiselo ochanekileyo we-injini ye-aero blades, ukukhuthaza ukuphuculwa kokuchaneka kokwenziwa kwe-aviation ye-aviation, kunye nokunceda ishishini lifikelele kubude obutsha.
