진공 자외선 카메라 렌즈의 접착기술 개발 = Adhesion Technology Development of Lyman-α Imaging Solar Telescope Mirror

다국어 초록 (Multilingual Abstract)

In this study, we analysis a cemented mirror for 3 mount material in steady - state using 'Finite elements analysis' for the purpose of making the cemented mirror of Lyman- solar telescope which is main payload of the STSAT-2 that is planned to blastoff the latter half of the year in 2005, be the minimum thermal stress and thermal transformation. we assume just two cases of temperature changes, which are worst cold case and worst hot case, according to an orbit character of satellite. As a result, the stress and transformation on commissure caused by the difference of the coefficient of thermal expansion is inquired out in order of Al-6063-T6, Ti-6AI-4V, SuperInvar besides stress on commissure and displacement of out 'of commissure is the maximum. Consequently It is safe to use Invar-fraction, But In the case of using AI-6063- T6 for satisfying mass requirement, is required more effectively thermal control system.
