Kuongororwa kwemashizha einjini yeaero kune zvinodiwa zvakanyanya kuti puratifomu igare yakasimba, yakarurama uye yakavimbika. Zvichienzaniswa nemapuratifomu ekuongorora echinyakare akadai sesimbi yakakandwa uye aruminiyamu, mapuratifomu egranite anoratidza mabhenefiti asingatsiviwi muzviratidzo zvakawanda zvakakosha.
I. Kugadzikana kwekupisa: "Chidziviriro chezvisikwa" pakurwisa kukanganiswa kwekupisa
Kuwanda kwekuwedzera kwekupisa kwemapuratifomu esimbi yakakandwa kunenge 10-12 × 10⁻⁶/℃, uye kwealuminium alloys kwakakwira kusvika 23×10⁻⁶/℃. Pasi pekupisa kunokonzerwa nekushanda kwemidziyo yekuona kana kuchinja kwekupisa kwezvakatipoteredza, kushanduka kwehukuru kunowanzoitika, zvichikonzera zvikanganiso zvekuona. Kuwanda kwekuwedzera kwekupisa kwepuratifomu yegranite kunongova (4-8) × 10⁻⁶/℃. Mukati mekushanduka kwekupisa kwe ±5℃, kuchinja kwehukuru hwepuratifomu yegranite yakareba mita imwe isingasviki 0.04μm, izvo zvinogona kupotsa zvaregeredzwa. Hunhu uhwu hwekuwedzera kwekupisa hwakaderera zvikuru hunopa nzvimbo yakagadzikana yekutarisa michina chaiyo senge laser interferometers nemichina yekuyera ine coordinate nhatu, kudzivirira kutsauka kwekuyera kwemavara emuti kunokonzerwa nekushanduka kwekupisa.
Ii. Kushanda kweAnti-vibration: "Chipingamupinyi Chinoshanda" Chekubvisa Kukanganiswa kweVibration
Munzvimbo yekugadzira ndege, kudedera kwezvakatipoteredza kunokonzerwa nekushanda kwezvishandiso zvemuchina uye kufamba kwevashandi kunowanzoitika. Mapuratifomu ealuminium alloy haana kuomarara kwakakwana, uye mapuratifomu esimbi akaumbwa ane mashandiro mashoma ekudzikamisa, zvichiita kuti zviome kudzikamisa zvinobudirira. Chimiro chekristaro chakasimba chiri mukati mepuratifomu yegranite chinopa hunhu hwakanaka hwekudzikamisa, nechiyero chekudzikamisa che0.05-0.1, chinova kashanu pane simbi yakaumbwa uye kagumi pane aluminium alloy. Kana kudedera kwekunze kukatumirwa kuchikuva, kunogona kuderedza simba rekudzikamisa neanopfuura 90% mukati memasekonzi 0.3, zvichiita kuti michina yekuona ikwanise kuburitsa data rakarurama munzvimbo inodedera.
Iii. Kusaomarara uye Kuramba Kupfeka: "Nhare Yakasimba" Inoita Kuti Ive Nekunyatsorongeka Kwenguva Refu
Mushure mekushandiswa kwenguva yakati, puratifomu yesimbi yakakandwa inogona kutsemuka nekuneta, izvo zvinokanganisa kururama kwayo. Mapuratifomu ealuminium alloy haana kuomarara uye haakwanise kupfeka zvakanaka, zvichiita kuti zviome kutsungirira kushandiswa kwemidziyo yekuongorora inorema. Huremu hwepuratifomu yegranite hunosvika 2.6-2.8g /cm³, simba rayo rekumanikidza rinodarika 200MPa, uye kuomarara kwayo kweMohs kuri 6-7. Kana ikaiswa mumitoro inorema uye kukweshana kwenguva refu kubva kumidziyo yekuongorora blade, haiwanzo kukuvara kana kushanduka. Data kubva kune rimwe bhizinesi rendege rinoratidza kuti mushure mekushandiswa kwenguva refu kwemakore masere, kuchinja kwegranite platform kuchiri kudzorwa mukati me ±0.1μm/m, nepo puratifomu yesimbi yakakandwa ichida kugadziriswazve mushure memakore matatu chete.
Iv. Kugadzikana Kwemakemikari: "Dombo rekona rakagadzikana" rekugadzirisa mamiriro ezvinhu akaomarara
Zvinhu zvemakemikari zvakaita sekuchenesa uye mafuta anoshandiswa mumabasa ekuongorora ndege. Mapuratifomu ealuminium alloy anowanzo ora, uye mapuratifomu esimbi anogonawo kukanganiswa nekunyatsorongeka nekuda kwe oxidation uye ngura. Granite inonyanya kuumbwa nezvicherwa zvakaita se quartz ne feldspar. Ine hunhu hwemakemikari hwakagadzikana, pH inokwana 1 kusvika 14, uye inogona kuramba kukanganiswa nezvinhu zvemakemikari zvakajairika. Hapana mvura yesimbi pamusoro payo, zvichiita kuti ive nzvimbo yakachena yekuona uye kudzivirira zvikanganiso zvekuyera zvinokonzerwa nekusvibiswa kwemakemikari.
V. Kururama Kwekugadzira Machining: "Nzvimbo Yakakodzera" Yekuyera Kwakarurama
Kuburikidza nematekinoroji epamusoro-soro akadai se magnetorheological polishing uye ion beam processing, granite platforms dzinogona kuwana processing accuracy ye ±0.1μm/m kuti ive flat uye Ra≤0.02μm kuti ive surface roughness, inodarika zvikuru cast iron platforms (±1μm/m kuti ive flatness) uye aluminium alloy platforms (±2μm/m kuti ive flatness). Iyi high-precision surface inopa reference chaiyo yekuisa ma sensors epamusoro-soro uye ma measurement probes, zvichiita kuti zvive nyore kuona three-dimensional contour measurements ye aero-injini blades pa 0.1μm level.
Mumamiriro ezvinhu anonyanya kudiwa ekuongorora mapanga einjini yeaero, mapuratifomu egranite, ane mabhenefiti akazara mukugadzikana kwekupisa, kuramba kudedera, kuomarara, kugadzikana kwemakemikari uye kunyatsogadzirwa, ave sarudzo yakanakisisa yekuona kuti kuongorora kwakarurama uye kuvimbika, zvichiisa hwaro hwakasimba hwekuvandudzwa kwemhando yepamusoro kwekugadzirwa kwendege.
