PaZhhimg, hatingopi granite chete—tinogadzira kugadzikana kwakakosha pabasa redu pazviyero zvishoma zvinogona kuenzana.
Nei Granite Isingatsiviwe muAerospace Metrology
Kunyange zvazvo zvinhu zvakagadzirwa nesimbi neceramics zvichikwanisa kubatwa zvakanaka muzvivakwa zvakareruka, granite yechisikigo inoramba iri chinhu chisingarambiki chinosarudzwa pamapuratifomu ekutarisa akagadzikana mumabasa emuchadenga ane mutengo wakakwirira. Zvakanakira zvayo zvakakosha:
- Kufamba-famba pasi pemutoro wepamusoro-soro: Inochengetedza kupfava kwemakumi emakore, kunyangwe pasi pemidziyo yemagetsi ine matani akawanda
- Kuzviparadzanisa kwemukati mesimba remvura: Kugona kunyorova kwemvura kwakakwirira kupfuura simbi yakakandwa kana simbi ne3–5×
- Kugadzikana kwekupisa: CTE ≈ 6.5 ppm/°C ine hysteresis shoma mukufamba kwezuva nezuva
- Isina magineti uye isingafambise: Yakachengeteka kune maavionics anonzwa uye bvunzo dzemagineti
Kune dzimba dzekuchenesa dzinosanganiswa nesatellite kana nzvimbo dzekuunganidza dzekupedzisira dzeinjini dzejeti—uko kudedera kunobva pasi kubva kuHVAC, macrane, kana nzira dzendege dziri pedyo kunotyisidzira kusimba kwekuyera—granite haisi sarudzo. Inokosha.
Kusundira Miganhu: Kugona Kwebasa Rakakura reZhhimg
Vatengesi vazhinji vanoisa granite yavo pa3m × 2m. Pa zhhimg, tinogara tichipa zvigadziko zvegranite zve monolithic zvinosvika 9m × 4m × 800mm, zvakagadzirwa nemuchina kusvika paGrade 00 flatness (≤ 2 + L/1000 µm) uye zvakapihwa chitupa neNational Institute of Metrology yeChina.
Mapurojekiti achangoburwa anosanganisira:
- Nzvimbo yegranite yakareba mamita 7.8 yekubatanidza injini dzendege dzekutengeserana, ine nzvimbo dzeT-slots dzakabatanidzwa, nzvimbo dzekudzika dzakaiswa pasi, uye nzvimbo dzekutevera laser.
- Puratifomu ine chitsuwa chine 6m × 3.5m ine denderedzwa re satellite structural test rig, ine magumo anoenderana ne vacuum uye kinematic mounting interfaces.
- Zvitsuwa zvegranite zvakagadziriswa nemagetsi zvakaiswa zvakananga pasi pefekitori—pasina maburi ekongiri—zvichishandisa zvigadziko zvedu zvekudzivirira mvura zvisina simba
Zvinhu zvikuru zvese zvinoitwa ne3D finite element analysis (FEA) panguva yekugadzira kuti ribbing ishande zvakanaka, rutsigiro rwenzvimbo, uye modal frequency - zvichiita kuti first-mode resonance irambe iri pamusoro pe120 Hz, isina ruzha rwemaindasitiri.
Kuzviparadzanisa Nekudedera: Yakavakirwa Mukati, Kwete Yakasungirirwa
Kuzviparadzanisa kwechokwadi kwekudengenyeka kunotanga padanho rezvinhu—asi zhhimg inoenderera mberi. Zvigadziko zvedu zvemhando yemuchadenga zvinosanganisa:
- Madhambi ekuderedza huwandu hwemasaisai akagadziriswa kuti adzivise mafrequency akatarwa
- Nzvimbo dzinoyangarara pasi dzine rabha yechisikigo kana zvinobvisa mhepo (sarudzo)
- Masensa ari pachikuva anowanikwa kuti aongorore nharaunda panguva chaiyo (tembiricha, kutsvedza, kudedera)
Maitiro aya anobatsira kuti kungave uri kushandisa rotor ye5-ton turbofan kana kuti star tracker optics, chiyero chako chepakutanga chinoramba chisina kukanganiswa.
Kubatsira kweZhhimg: Kunyatsojeka Pachikero, Pasina Kubvumirana
Tichishanda kubva panzvimbo yedu inosvika 200,000㎡ muShandong—ine nzvimbo dzekugadzira michina dzinodzorwa nemamiriro ekunze (20±0.3°C), magrinder e5-axis CNC bridge, uye ma lab emetrology ari mukati—tinobatanidza kusarudzwa kwematombo ehunyanzvi nekushandiswa kwemaindasitiri.
Chivharo chega chega cheJinan Black granite chinogara kwenguva refu kupfuura makore matatu chisati chagadziriswa, zvichivimbisa kusununguka kwekushushikana mukati. Chitupa chekupedzisira chinosanganisira:
- Mamepu eLaser interferometer flatness
- Mishumo yehuwandu hweResonance
- Kuongororwa kunoteverwa zvichienderana neASME B89.3.7 uye JJG 117-2013
Kune vanogadzira zvinhu zvemuchadenga nemakambani ezvemuchadenga, izvi hazvisi zvekungotenga chete—zvinoderedza njodzi.
