Uburyo bwo kurangiza ubuso
Gusya no Gusukura:
Intambwe kuva ku gusya neza kugeza ku gusya burundu ni yo igaragaza ubwiza bw'ubuso n'ubugari:
- Gusya nabi: Bikuraho ibikoresho byinshi, bigatuma ubugari bushobora kwihanganira ± 0.05 mm
- Gusya neza: Bigabanya ubukana bw'ubuso kugeza kuri Ra ≈ 0.1-0.5 μm
- Gusukura: Bigera ku iherezo rya nyuma ry'ubuso bwa Ra ≤ 0.5 nm
Gutunganya mu buryo bw'umuvuduko ugereranije no gutunganya hakoreshejwe mudasobwa:
Gutunganya ubushyuhe gakondo bishobora kugera kuri λ/20 ku duce duto kugeza kuri giciriritse (kugeza kuri mm 150). Ku duce duto cyangwa iyo bikenewe ko habaho ikoranabuhanga rinini, gutunganya hakoreshejwe mudasobwa (CCP) cyangwa kurangiza hakoreshejwe magnetorheological (MRF) bituma:
- Ubugari buhamye ku gice cy'ubutaka gifite uburebure bwa mm 300-500
- Igihe cyo gukora cyagabanutseho 40-60%
- Ubushobozi bwo gukosora amakosa y'impinduka zo hagati mu kirere
Gutunganya no Gushyiramo Ubushyuhe:
Nkuko byavuzwe mbere, gufunga neza ni ingenzi cyane mu kugabanya stress:
- Ubushyuhe bwo gushyuha: 0.8 × Tg (ubushyuhe bwo guhindura ikirahure)
- Igihe cyo kwinika: amasaha 4-8 (ibipimo bifite ubugari kare)
- Igipimo cy'ubukonje: 1-5°C/isaha unyuze mu gice cyo gukonjesha
Ku birahuri bya CTE nke nka ULE na Zerodur, hashobora kuba hakenewe ubwiyongere bw'ubushyuhe kugira ngo habeho ubuziranenge buhamye. "Inzira yo gusaza" ya Zerodur ikubiyemo gusimbuza ibikoresho hagati ya 0°C na 100°C mu gihe cy'ibyumweru byinshi kugira ngo habeho ubushyuhe buhamye.
Igenzura ry'Ubuziranenge n'Ubumenyi bw'Ibintu
Kugenzura ko ibipimo byagezweho bisaba gupima ibintu mu buryo buhanitse:
Igipimo cy'ubugari:

Ibitekerezo byo guhuza: Gushyiramo uduce duto tw'ikirahure muri sisitemu yo guhuza
Gushyira mu bikorwa neza ibikoresho by'ikirahure bitanga umusaruro uhagije bisaba kwitabwaho mu gushyiraho, gucunga ubushyuhe, no kugenzura ibidukikije.
Gushyiraho no Gushyiraho
Amahame yo gushyiraho Kinematic:
Kugira ngo habeho guhuza neza, substrates zigomba gushyirwaho hakoreshejwe uburyo bwa kinematic hakoreshejwe inkingi eshatu kugira ngo hirindwe ko hashyirwaho stress. Imiterere y'aho zishyirwa iterwa n'ikoreshwa:
- Ibikoresho byo gupakira ubuki: Ku bikoresho binini kandi byoroheje bisaba gukomera cyane
- Gufunga impande: Ku bice by'imbere aho impande zombi zigomba kuguma kugerwaho
- Ibikoresho bifatanye: Gukoresha kole y'urumuri cyangwa epoksiya zigabanya imyuka
Kugorekwa biterwa n'umuvuduko w'ihungabana:
Nubwo hakoreshejwe uburyo bwa kinematic, imbaraga zo gufunga zishobora gutuma ubuso buhindagurika. Ku bijyanye no kwihanganira ubugari bwa λ/20 kuri substrate ya silica ya mm 200, imbaraga ntarengwa zo gufunga ntizigomba kurenza 10 N ikwirakwijwe ahantu hagera kuri mm² 100 kugira ngo hirindwe ko ubugari burenga urugero rw'ubugari.
Imicungire y'ubushyuhe
Kugenzura ubushyuhe:
Kugira ngo habeho guhuza neza cyane, kugenzura ubushyuhe akenshi ni ngombwa:
