Juyin juya hali a binciken injin Aero-engine: Yadda Ake Samun Ma'aunin Zagaye Mai Girma Uku na Matakin 0.1μ M akan Dandalin Granite?

Daidaiton ruwan wukake na injin Aero yana da alaƙa da aikin injin gabaɗaya, kuma ma'aunin siffar murabba'i uku a matakin 0.1μm ya zama babban buƙatar masana'anta. Tsarin gargajiya yana da wahalar cika ƙa'idodi. Tsarin granite, tare da manyan fa'idodi guda uku, suna ba da tallafi mai inganci don gano daidai.

Daidaiton zafin jiki yana gina tushe mai kyau. Matsakaicin faɗaɗa zafin jiki na granite yana da (4-8) ×10⁻⁶/℃ kawai, wanda ya fi ƙasa da kashi 60% fiye da na ƙarfe. A ƙarƙashin canjin zafin jiki na ±1℃, canjin girman dandamali mai tsawon mita 1 bai wuce 0.008μm ba, wanda zai iya samar da farfajiyar tunani akai-akai ga kayan aiki kamar na'urorin auna laser da injunan aunawa masu daidaitawa uku, yana guje wa tarin kurakuran aunawa da lalacewar zafi ke haifarwa. A halin yanzu, yawansa ya kai 2.6-2.8g/cm³, ƙarfin matsi ya wuce 200MPa, yana da juriya ga lalacewa, kuma yana tabbatar da cewa daidaiton ba ya canzawa a tsawon lokaci.

Kyakkyawan juriya ga girgiza da kuma keɓewar tsangwama ga muhalli. Cibiyar nazarin jiragen sama tana girgiza akai-akai. Tsarin lu'ulu'u na musamman na granite yana sa rabon damping ɗinsa ya kai 0.05-0.1, wanda ya ninka ƙarfe sau 5-10. Yana iya rage ƙarfin girgiza sama da kashi 90% cikin daƙiƙa 0.3. Idan aka yi la'akari da aunawa da na'urar bin diddigin laser a matsayin misali, idan aka haɗa shi da dandamalin granite, ana iya sarrafa canjin hasken laser a cikin ±0.02μm, wanda hakan ke inganta daidaiton auna kurakuran bayanin martaba na ruwan wukake sosai.

Haɗakar ƙwarewar daidaici da hankali yana ƙara inganci. Bayan sarrafa daidaito kamar gogewar magnetorheological, lanƙwasa na dandamalin granite ya kai ±0.1μm/m, kuma rashin daidaiton saman Ra shine ≤0.02μm. Bayan an haɗa shi da ma'aunin grating na nanoscale da algorithms na AI, daidaiton ma'aunin maki ɗaya ya kai 0.05μm, an rage kuskuren gabaɗaya zuwa ±0.1μm, ingancin ganowa yana ƙaruwa da 30%, kuma ƙimar gano lahani ta kai 99.9%.

Dandalin dutse, tare da ingantaccen aikinsu, suna kare ainihin ma'aunin ruwan wukake na injinan iska, suna haɓaka haɓaka daidaiton masana'antar jiragen sama, da kuma taimakawa masana'antar ta kai sabon matsayi.
