Kusintha pakuwunika kwa Blade ya Aero-injini: Momwe Mungakwaniritsire 0.1μ M-level atatu-dimensional Contour Measurement pa Mapulani a Granite?

Kulondola kwa masamba a injini ya aero kumagwirizana ndi momwe makinawo amagwirira ntchito, ndipo kuyeza kozungulira kozungulira katatu pamlingo wa 0.1μm kwakhala chofunikira kwambiri popanga. Mapulatifomu achikhalidwe ndi ovuta kukwaniritsa miyezo. Mapulatifomu a granite, omwe ali ndi maubwino atatu akuluakulu, amapereka chithandizo chodalirika kuti azindikire bwino.

Kukhazikika kwa kutentha kumamanga maziko enieni. Coefficient of thermal expansion of granite ndi (4-8) × 10⁻⁶/℃, yomwe ili yotsika kuposa 60% kuposa yazitsulo. Pansi pa kusinthasintha kwa kutentha kwa ± 1 ℃, kusintha kwa kukula kwa nsanja ya 1-mita yayitali ndi yochepera 0.008μm, yomwe ingapereke malo owonetsera nthawi zonse pazida monga laser interferometers ndi makina atatu oyezera, kupeŵa kudzikundikira kwa zolakwika zoyezera zomwe zimachitika chifukwa cha matenthedwe matenthedwe. Pakadali pano, kachulukidwe kake kamafika pa 2.6-2.8g/cm³, mphamvu yake yopondereza imaposa 200MPa, imakhala yosavala, ndikuwonetsetsa kuti kulondola kumakhalabe kosasinthika pakagwiritsidwe ntchito kwanthawi yayitali.

Kukaniza kugwedezeka kwapadera komanso kudzipatula kusokoneza zachilengedwe. Msonkhano wa pandege umanjenjemera pafupipafupi. Mapangidwe apadera a kristalo a granite amapangitsa kuti chiwopsezo chake chifike pa 0.05-0.1, chomwe ndi nthawi 5-10 kuposa zitsulo. Itha kutsitsa mphamvu yopitilira 90% ya mphamvu yakugwedezeka mkati mwa masekondi 0.3. Kutengera muyeso ndi tracker ya laser mwachitsanzo, ikaphatikizidwa ndi nsanja ya granite, laser beam offset imatha kuwongoleredwa mkati mwa ± 0.02μm, kuwongolera kwambiri kuyeza kulondola kwa zolakwika za mbiri ya tsamba.

Kuphatikizika kwa luso laluso ndi luntha kumawonjezera luso. Pambuyo pokonza molondola kwambiri monga kupukuta kwa magnetorheological, flatness ya granite platform imafika ± 0.1μm/m, ndipo pamwamba roughness Ra ndi ≤0.02μm. Pambuyo pophatikizidwa ndi olamulira a nanoscale grating ndi ma algorithms a AI, kulondola kwa mfundo imodzi kumafika ku 0.05μm, cholakwika chonsecho chimachepetsedwa kufika ± 0.1μm, kuwonetsetsa bwino kumawonjezeka ndi 30%, ndipo chiwerengero cha chilema chimafika 99.9%.

Mapulatifomu a granite, okhala ndi magwiridwe antchito okhazikika komanso odalirika, amateteza kuyeza kolondola kwa masamba a injini ya aero, amalimbikitsa kukweza kulondola kwa kayendetsedwe ka ndege, ndikuthandizira makampani kuti afike pamtunda watsopano.
