This paper presents the problem that the ball-hinge supporting structure of a certain type of primary mirror will lead to the astigmatism when the external condition varies. Based on the research on the ball-hinge supporting structure, a novel flexure supporting structure was developed and optimized with numerical analysis. Some environment experiments were conducted, and the results demonstrated that the supporting structure had large dynamic stiffness, and was better suitable for the assembly stress and thermal stress. This flexure supporting structure makes the mirror surface figure stable in a wide temperature range, and the RMS value of 0.02λ(λ=632.8 nm) when the gravitational load varies, which means the design requirement is satisfied.","PeriodicalId":68706,"journal":{"name":"光机电信息","volume":"28 1","pages":"28-34"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70574684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
