Ni izihe nyungu za granite ya platform kurenza izindi mbuga zo kugenzura mugenzura ibyuma bya moteri ya aero?

?
Kugenzura ibyuma bya moteri ya aero bifite ibisabwa cyane kugirango bihamye, byukuri kandi byizewe byurubuga. Ugereranije na platifike yo kugenzura gakondo nka fer na aluminiyumu, ibyuma bya granite byerekana ibyiza bidasubirwaho mubipimo byinshi byingenzi. ?
I. Ihungabana ryubushyuhe: "Ingabo Kamere" Kurwanya Ubushyuhe
Coefficient yo kwagura ubushyuhe bwumuriro wibyuma bigera kuri 10-12 × 10⁻⁶ / ℃, naho ibya aluminiyumu ni hejuru ya 23 × 10⁻⁶ / ℃. Munsi yubushyuhe buterwa nigikorwa cyibikoresho byo gutahura cyangwa ihindagurika ryubushyuhe bwibidukikije, ihinduka ryimiterere rishobora kubaho, biganisha ku makosa yo gutahura. Coefficient yo kwagura ubushyuhe bwa platform ya granite ni (4-8) × 10⁻⁶ / ℃. Mubushyuhe bwubushyuhe bwa ± 5 ℃, ihinduka ryikigereranyo cya metero 1 z'uburebure bwa granite ntiri munsi ya 0.04μm, ishobora kwirengagizwa. Uku kwaguka kwinshi cyane kurwego rwo hejuru rutanga ubuso buhamye bwibikoresho bisobanutse nka laser interferometero hamwe na mashini eshatu zipima imashini, birinda gutandukana gupima ibipimo byatewe no guhindura ubushyuhe. ?

Ii. Imikorere yo kurwanya vibrasiya: "Inzitizi Nziza" yo Kurandura Kwivanga
Mu mahugurwa yo gukora indege, kunyeganyeza ibidukikije biterwa no gukoresha ibikoresho byimashini no kugenda kwabakozi ni kenshi. Aluminiyumu ya aluminiyumu ifite ubukana budahagije, kandi ibyuma bikozwe mucyuma bifite imikorere mike yo kugabanya, bigatuma bigorana guhagarika neza kunyeganyega. Imiterere yuzuye ya kirisiti imbere muri granite ya platifike irayiha ibintu byiza cyane byo gusiba, hamwe nikigereranyo cya 0.05-0.1, kikaba cyikubye inshuro eshanu icyuma gikozwe hamwe ninshuro icumi za aluminiyumu. Iyo kunyeganyega hanze byoherejwe kuri platifomu, birashobora kongera ingufu zinyeganyeza hejuru ya 90% mumasegonda 0.3, byemeza ko ibikoresho byo gutahura bishobora gutanga amakuru yukuri mubidukikije. ?
Iii. Gukomera no Kwambara Kurwanya: "Igihome gikomeye" Kwemeza neza igihe kirekire
Nyuma yo gukoreshwa mugihe runaka, icyuma gikozwe mucyuma gikunda gucika intege, bigira ingaruka kumyizerere yacyo. Aluminiyumu ya aluminiyumu ifite ubukana buke no kutambara neza, bigatuma bigorana kwihanganira ikoreshwa ryibikoresho bigenzura cyane. Ubucucike bwa platform ya granite bugera kuri 2,6-2.8g / cm³, imbaraga zayo zo kwikuramo zirenga 200MPa, naho ubukana bwa Mohs ni 6-7. Iyo ikorewe imitwaro iremereye hamwe no guterana igihe kirekire kubikoresho byo kugenzura ibyuma, ntabwo byoroshye kwambara cyangwa guhindura ibintu. Amakuru aturuka mu kigo runaka cyindege yerekana ko nyuma yo gukoreshwa ubudahwema kumyaka umunani, ihinduka ryimiterere ya granite iracyagenzurwa muri ± 0.1μm / m, mugihe icyuma gikozwe mubyuma gikeneye gusubirwamo nyuma yimyaka itatu gusa. ?
Iv. Imiti ihamye: "Stable Cornerstone" yo Guhuza Ibidukikije bigoye
Imiti yimiti nkibikoresho byogusukura hamwe namavuta ikoreshwa kenshi mumahugurwa yo kugenzura indege. Amashanyarazi ya aluminiyumu akunda kwangirika, kandi ibyuma bikozwe mu byuma nabyo bishobora kugira ingaruka zukuri kubera okiside no kubora. Granite igizwe ahanini namabuye y'agaciro nka quartz na feldspar. Ifite imiti ihamye, kwihanganira pH iri hagati ya 1 na 14, kandi irashobora kurwanya isuri yibintu bisanzwe. Nta mvura ya ion igaragara ku buso bwayo, ituma ibidukikije bisukurwa neza kandi birinda amakosa yo gupimwa yatewe n’umwanda. ?
V. Gukora neza neza: "Ideal Base" yo gupima neza
Binyuze muri tekinoroji ya ultra-precision nka magnetorheologiya polishinge hamwe no gutunganya ibiti bya ion, urubuga rwa granite rushobora kugera kuri gutunganya 0.1 mμm / m kuburinganire na Ra≤0.02μm kubutaka bukabije, burenze kure ubw'ibyuma bikozwe mu cyuma (± 1μm / m kuburinganire) hamwe na aluminiyumu ivanze (± 2μm / m kuburinganire). Ubu buso buhanitse butanga amakuru yukuri yo kwishyiriraho ibyuma bisobanutse neza hamwe nubushakashatsi bwo gupima, byorohereza kumenya ibipimo bitatu-bipima ibipimo bya metero ya moteri ya moteri kuri 0.1μm. ?
Mugihe gikenewe cyane cyo kugenzura ibyuma bya moteri ya aero, urubuga rwa granite, hamwe nibyiza byabo byuzuye mumashanyarazi yumuriro, kurwanya ibinyeganyega, gukomera, imiti ihamye no gutunganya neza, byahindutse uburyo bwiza bwo kugenzura niba igenzurwa ryukuri kandi ryizewe, rishyiraho urufatiro rukomeye rwiterambere ryiza ryiterambere ryinganda zindege.
