Shanduko muAero-injini Blade yekuongorora: Maitiro eKuwana 0.1μ M-chikamu chetatu-dimensional Contour Measurement paGranite Platform?

Kurongeka kwemaaero ejini blades kune hukama nekuita kwese kwemuchina, uye matatu-dimensional contour kuyerwa padanho re 0.1μm chave chinhu chikuru chekugadzira chinodiwa. Mapuratifomu echinyakare akaoma kuzadzisa zviyero. Granite mapuratifomu, ane matatu makuru mabhenefiti, anopa rutsigiro rwakavimbika rwekuona chaiko.

Kugadzikana kwekupisa kunovaka nheyo chaiyo. Iyo coefficient yekuwedzera kwekupisa kwegranite chete (4-8) × 10⁻⁶/℃, iyo inopfuura 60% yakaderera pane iyo yesimbi. Pasi pekuchinja kwekushisa kwe ± 1 ℃, saizi yekuchinja kwe 1-mita-yakareba chikuva isingasviki 0.008μm, iyo inogona kupa inogara ichitariswa pamusoro pemidziyo yakaita se laser interferometers uye matatu-coordinate yekuyeresa michina, kudzivirira kuunganidzwa kwekuyerwa kwekukanganisa kunokonzerwa nekupisa kwekupisa. Zvichakadaro, density yaro inosvika 2.6-2.8g/cm³, simba rayo rekumanikidza rinopfuura 200MPa, haipfeki, uye inova nechokwadi chekuti iko kurongeka kunoramba kusingachinji pakushandiswa kwenguva refu.

Yakasarudzika vibration kuramba uye kukanganiswa kwezvakatipoteredza kuparadzaniswa. Musangano wezvendege unodedera nguva zhinji. Iyo yakasarudzika yekristaro chimiro chegranite chinoita kuti daping ratio isvike 0.05-0.1, inova 5-10 nguva yesimbi. Inogona kuderedza kupfuura 90% yesimba rekudengenyeka mukati memasekondi 0.3. Kutora kuyerwa nelaser tracker semuenzaniso, kana yasanganiswa nepuratifomu yegranite, iyo laser beam offset inogona kudzorwa mukati me ± 0.02μm, ichivandudza zvakanyanya kuyerwa kwekuyerwa kwekukanganisa kweblade profile.

Iko kubatanidzwa kwehunyanzvi hwekugadzira uye hungwaru kunowedzera kushanda zvakanaka. Mushure mekupedzisira-kunyatsogadziriswa senge magnetorheological polishing, flatness yegranite platform inosvika ± 0.1μm/m, uye kushata kwepamusoro Ra iri ≤0.02μm. Mushure mekubatanidzwa ne nanoscale grating vatongi uye AI algorithms, iyo imwechete-point kuyerwa kwechiyero kunosvika 0.05μm, kukanganisa kwese kunoderedzwa kusvika ± 0.1μm, kutaridzika kwekuona kunowedzera ne30%, uye chiyero chekuremara chinosvika 99.9%.

Mapuratifomu eGranite, nekuita kwawo kwakadzikama uye kwakavimbika, chengetedza kuyerwa chaiko kweaero injini blades, kusimudzira kukwidziridzwa kwekugadzirwa kwendege, uye kubatsira indasitiri kusvika pakakwirira.
