Kuchinja kwekuongorora kweAero-injini Blade: Maitiro Ekuwana Kuyerwa kweContour ye0.1μ M-level three-dimensional paGranite Platforms?

Kururama kwemaburi einjini yeaero kunoenderana nekushanda kwese kwemuchina, uye kuyerwa kwemakona matatu padanho re0.1μm kwave chinhu chikuru chinodiwa pakugadzira. Mapuratifomu echinyakare akaoma kusangana nezvinodiwa. Mapuratifomu egranite, ane zvakanakira zvitatu zvikuru, anopa rutsigiro rwakavimbika rwekuona kwakarurama.

Kugadzikana kwekupisa kunovaka hwaro hwakarurama. Kuwanda kwekuwedzera kwekupisa kwegranite kunongova (4-8) ×10⁻⁶/℃, iyo yakaderera kupfuura 60% pane yesimbi. Kana tembiricha ichichinja-chinja, saizi yepuratifomu yakareba mita imwe isingasviki 0.008μm, izvo zvinogona kupa nzvimbo inogara ichitaridzirwa yemidziyo yakaita se laser interferometers nemichina yekuyera ine mitsetse mitatu, zvichidzivirira kuunganidzwa kwezvikanganiso zvekuyera zvinokonzerwa nekushanduka kwekupisa. Panguva imwe chete, huwandu hwayo hunosvika 2.6-2.8g/cm³, simba rayo rekudzvanya rinodarika 200MPa, haipfeki, uye inoita kuti kururama kusachinje kana ikashandiswa kwenguva refu.

Kuramba kusingadzoreki kwekudengenyeka uye kuparadzaniswa kwezvakatipoteredza. Nzvimbo yekufambisa ndege inodedera nguva nenguva. Chimiro chegirazi chakasiyana chinoita kuti chiyero chayo chekunyorovesa mvura chisvike 0.05-0.1, chinova 5-10 zvakapetwa kupfuura simbi. Inogona kuderedza simba rekudengenyeka rinodarika 90% mukati memasekondi 0.3. Tichitora chiyero nelaser tracker semuenzaniso, kana chikabatanidzwa nepuratifomu yegranite, laser beam offset inogona kudzorwa mukati me ±0.02μm, zvichivandudza zvakanyanya kuyera kwezvikanganiso zve blade profile.

Kubatanidzwa kwehunyanzvi hwekugadzira zvinhu nemazvo uye hungwaru kunowedzera kushanda zvakanaka. Mushure mekugadzirisa zvinhu nemazvo zvakanyanya sekupukuta kwemagnetorheological, kutsetseka kwepuratifomu yegranite kunosvika ±0.1μm/m, uye kuomarara kwepamusoro kweRa kuri ≤0.02μm. Mushure mekubatanidzwa ne nanoscale grating rulers uye AI algorithms, kurongeka kwekuyera kwepoint imwe chete kunosvika 0.05μm, kukanganisa kwese kunoderedzwa kusvika ±0.1μm, kushanda zvakanaka kwekuona kunowedzerwa ne30%, uye chiyero chekuona defect chinosvika 99.9%.

Mapuratifomu egranite, nekushanda kwawo kwakasimba uye kwakavimbika, anochengetedza kuyerwa kwakarurama kwemashizha einjini dzemuchadenga, anokurudzira kuvandudzwa kwekururama kwekugadzirwa kwendege, uye anobatsira indasitiri kusvika pakakwirira.
