Qhov tseeb ntawm aero engine blades muaj feem xyuam rau tag nrho cov kev ua tau zoo ntawm lub tshuab, thiab peb-dimensional contour ntsuas ntawm qib 0.1μm tau dhau los ua qhov tseem ceeb ntawm kev tsim khoom. Traditional platforms nyuaj ua kom tau raws li cov qauv. Granite platforms, nrog lawv peb qhov zoo tshaj plaws, muab kev txhawb nqa txhim khu kev qha rau kev kuaj pom tseeb.
Thermal stability tsim lub hauv paus meej. Lub coefficient ntawm thermal expansion ntawm granite tsuas yog (4-8) × 10⁻⁶ / ℃, uas yog ntau tshaj 60% qis dua cov hlau. Raws li qhov kub thiab txias ntawm ± 1 ℃, qhov hloov pauv loj ntawm 1-meter-ntev platform yog tsawg dua 0.008μm, uas tuaj yeem muab qhov chaw siv tas li rau cov khoom siv xws li laser interferometers thiab peb-coordinate ntsuas cov cav tov, zam qhov tsub zuj zuj ntawm kev ntsuas yuam kev los ntawm thermal deformation. Lub caij no, nws qhov ceev nce mus txog 2.6-2.8g / cm³, nws lub zog compressive tshaj 200MPa, nws yog hnav-tiv taus, thiab xyuas kom meej tias qhov tseeb tseem tsis hloov pauv rau kev siv mus ntev.
Kev vibration tsis kam thiab ib puag ncig cuam tshuam kev sib cais. Lub aviation Rhiav vibrates nquag. Cov qauv siv lead ua tshwj xeeb ntawm granite ua rau nws qhov sib piv damping ncav cuag 0.05-0.1, uas yog 5-10 npaug ntawm cov hlau. Nws tuaj yeem ua rau ntau dua 90% ntawm lub zog vibration hauv 0.3 vib nas this. Kev ntsuas nrog lub laser tracker ua piv txwv, thaum ua ke nrog granite platform, laser beam offset tuaj yeem tswj tau li ntawm ± 0.02μm, txhim kho qhov ntsuas qhov tseeb ntawm cov hniav profile yuam kev.
Kev sib koom ua ke ntawm precision craftsmanship thiab txawj ntse txhim kho efficiency. Tom qab kev ua tiav ultra-precision xws li magnetorheological polishing, qhov flatness ntawm granite platform nce mus txog ± 0.1μm / m, thiab qhov roughness Ra yog ≤0.02μm. Tom qab ua ke nrog nanoscale grating rulers thiab AI algorithms, qhov ntsuas qhov tseeb ib leeg nce mus txog 0.05μm, qhov yuam kev tag nrho raug txo mus rau ± 0.1μm, qhov kev tshawb pom kev ua haujlwm tau nce 30%, thiab qhov ntsuas qhov tsis raug mus txog 99.9%.
Granite platforms, nrog rau lawv cov kev ua tau zoo thiab txhim khu kev qha, tiv thaiv qhov ntsuas qhov tseeb ntawm lub tshuab hluav taws xob aero, txhawb kev txhim kho kev lag luam aviation raug raug, thiab pab kev lag luam mus txog qhov siab tshiab.
