The proposed three-point flexural mount based on a cartwheel flexure can maintain the surface figure of the PMA in a horizontal optical testing layout. The on-orbit surface error of the PMA causes significant degradation in image quality. On-ground optical testing cannot determine the zero-gravity figure of the PMA due to surface distortion by gravity. We unveiled the crucial fact that through a delicate mounting structure design, the surface figure can remain constant precisely without inducing distinguishable astigmatism when PMA rotates with respect to the optical axis, and the figure can be considered as the zero-gravity surface figure on the orbit. A design case is described to show the lightweight design of a SiC mirror and the optimal flexural mounting. Topology optimization and integrated opto-mechanical analysis using the finite element method are utilized in the design process. The Primary Mirror and mounting structures were fabricated and assembled. After the PMA mirror surface was polished to \u03bb\/50 RMS, optical testing in different clocking configurations was performed, respectively, through rotating the PMA by multiple angles. Test results show that the surface figure remained invariant, indicating that gravity release on the orbit will not cause an additional surface error. Vibration tests including sweep sine and random vibration were also performed to validate the mechanical design. The requirements for the mounting technique in space were qualified.<\/jats:p>","DOI":"10.1063\/1.4986042","type":"journal-article","created":{"date-parts":[[2017,12,11]],"date-time":"2017-12-11T17:02:58Z","timestamp":1513011778000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":25,"title":["Optimal design of a \u03a6760 mm lightweight SiC mirror and the flexural mount for a space telescope"],"prefix":"10.1063","volume":"88","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5239-6789","authenticated-orcid":false,"given":"Zongxuan","family":"Li","sequence":"first","affiliation":[{"name":"Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences , Changchun 130033, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xue","family":"Chen","sequence":"additional","affiliation":[{"name":"Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences , Changchun 130033, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shaoju","family":"Wang","sequence":"additional","affiliation":[{"name":"Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences , Changchun 130033, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guang","family":"Jin","sequence":"additional","affiliation":[{"name":"Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences , Changchun 130033, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2017,12,11]]},"reference":[{"key":"2023070416065728700_c1","doi-asserted-by":"publisher","first-page":"8962","DOI":"10.1364\/ao.55.008962","volume":"55","year":"2016","journal-title":"Appl.
