Hauv kev tsim khoom siv hauv aerospace—qhov twg qhov kev kam rau siab ntsuas hauv microns thiab kev ua tiav ntawm lub luag haujlwm nyob ntawm qhov rov ua dua ntawm nanometer-level—lub hauv paus ntawm txhua qhov kev tshuaj xyuas tseem ceeb lossis kev sib dhos yuav tsum tsis txav chaw, tsis muaj zog, thiab tsis muaj cua sov. Yog vim li cas cov thawj coj hauv aerospace precision components integrating ntau zuj zus vam khom rau qhov lojcov hauv paus graniterau cov chaw teeb tsa cav, cov khoom siv kuaj xyuas satellite, thiab cov hlwb metrology tis.
Ntawm zhhimg, peb tsis yog tsuas yog muab cov granite xwb—peb tsim kom muaj kev ruaj khov uas tseem ceeb heev rau ntau qhov ntsuas uas tsawg tus neeg tuaj yeem sib piv tau.
Vim li cas Granite Tseem Tsis Tau Hloov Chaw Hauv Aerospace Metrology
Txawm hais tias cov khoom sib xyaw thiab cov khoom siv ceramic tau txais kev rub tawm hauv cov qauv sib dua, cov granite ntuj tseem yog cov khoom siv tsis muaj kev sib cav rau kev xaiv rau cov platforms siv tau ruaj khov hauv cov haujlwm aerospace uas muaj nqis siab. Nws cov txiaj ntsig yog qhov tseem ceeb:
- Yuav luag tsis muaj kev nkag mus rau hauv qab qhov hnyav: Tswj tau qhov tiaj tiaj rau ntau xyoo, txawm tias nyob hauv cov khoom siv ntau tuj
- Kev rho tawm kev co ntawm sab hauv: Muaj peev xwm ua kom lub zog ntub 3–5 × siab dua li cov hlau cam khwb lossis hlau
- Kev ruaj khov ntawm cua sov: CTE ≈ 6.5 ppm/°C nrog qhov tsawg kawg nkaus hysteresis thoob plaws txhua hnub voj voog
- Tsis yog hlau nplaum & tsis ua hluav taws xob: Muaj kev nyab xeeb rau kev sim avionics thiab magnetic bearing
Rau cov chav huv si uas muaj kev sib txuas ntawm satellite lossis cov chaw sib dhos kawg ntawm lub cav dav hlau—qhov twg cov kev co hauv av los ntawm HVAC, cranes, lossis cov kev khiav tsheb ze ze ua rau muaj kev phom sij rau kev ntsuas—granite tsis yog xaiv tau. Nws yog qhov tseem ceeb.
Thawb Cov Kev Txwv: zhhimg lub peev xwm ua haujlwm hnyav
Muaj ntau tus neeg muag khoom txwv lawv cov khoom granite ntawm 3m × 2m. Ntawm zhhimg, peb ib txwm xa cov pob zeb granite monolithic txog li 9m × 4m × 800mm, tshuab rau Qib 00 tiaj tiaj (≤ 2 + L/1000 µm) thiab tau ntawv pov thawj los ntawm Tuam Tshoj Lub Koom Haum National Institute of Metrology.
Cov haujlwm tsis ntev los no suav nrog:
- Lub hauv paus granite ntev 7.8m rau lub tshuab sib dhos lub cav dav hlau lag luam, uas muaj cov qhov T-slots, cov ntsiab lus hauv av, thiab cov zes laser tracker.
- Ib lub platform ob-kob 6m × 3.5m rau lub tshuab kuaj xyuas lub ntiaj teb qis-orbit, nrog rau qhov chaw tiav uas sib xws nrog lub tshuab nqus tsev thiab cov khoom siv kinematic mounting interfaces.
- Cov kob granite uas raug cais tawm los ntawm kev co uas raug teeb tsa ncaj qha rau ntawm cov plag tsev Hoobkas—tsis muaj cov ncej pob zeb—siv peb cov khoom siv passive damping mounts
Txhua yam khoom loj raug tshuaj xyuas 3D finite element analysis (FEA) thaum lub sijhawm tsim qauv los txhim kho qhov ribbing, qhov chaw txhawb nqa, thiab modal frequencies—ua kom ntseeg tau tias thawj hom resonance nyob siab dua 120 Hz, meej meej ntawm cov suab nrov hauv kev lag luam.
Kev Rho Tawm Kev co: Ua-Hauv, Tsis Bolted-On
Kev rho tawm kev co tiag tiag pib ntawm theem khoom siv - tab sis zhhimg mus ntxiv. Peb cov hauv paus aerospace-grade sib xyaw ua ke:
- Cov dampers tuned rau kev txo qhov zaus uas tau tsom mus rau
- Cov khoom siv hauv pem teb uas ntab nrog cov roj hmab ntuj lossis cov khoom siv cais cua (xaiv tau)
- Cov sensor nyob rau hauv-platform zes rau lub sijhawm tiag tiag saib xyuas ib puag ncig (kub, qaij, kev co)
Txoj kev qhia no ua kom ntseeg tau tias txawm tias koj tab tom teeb tsa lub rotor turbofan 5-tuj lossis kho lub hnub qub tracker optics, koj qhov kev ntsuas tseem tsis tau cuam tshuam.
Qhov Zoo ntawm zhhimg: Kev Ua Tau Zoo ntawm Qhov Ntsuas, Tsis Muaj Kev Txom Nyem
Ua haujlwm los ntawm peb lub chaw ua haujlwm loj 200,000㎡ hauv Shandong—nrog cov chaw ua haujlwm tswj huab cua (20±0.3°C), 5-axis CNC bridge grinders, thiab cov chaw kuaj ntsuas hauv tsev—peb muab kev xaiv pob zeb ua tes ua nrog kev ua tiav hauv kev lag luam.
Txhua lub pob zeb Jinan Black granite muaj hnub nyoog ≥3 xyoos ua ntej ua tiav, lav qhov kev ntxhov siab sab hauv. Daim ntawv pov thawj kawg suav nrog:
- Daim ntawv qhia txog kev sib tshuam ntawm laser interferometer
- Cov ntawv qhia txog zaus resonance
- Kev ntsuas tau raws li ASME B89.3.7 thiab JJG 117-2013
Rau cov tuam txhab tsim khoom siv hauv aerospace OEMs thiab cov koom haum tsim khoom siv hauv qhov chaw, qhov no tsis yog tsuas yog kev yuav khoom xwb - nws yog kev txo qis kev pheej hmoo.
