Abstract:In order to guarantee high component structure stiffness and good primary mirror thermal dimensional stability of primary mirror of marine laser communication system,the flexible support was optimal designed.Based on primary mirror component structure character,flexible support design scheme was proposed.The primary mirror flexible support was presented by the adjustment of circle arc length and the radius direction thinnest thickness.Finally,the analysis of primary mirror surface figure accuracy,primary mirror component stiffness and contact stress was carried out by Finite Element Method (FEM).As a result,from the above parameters variation,the flexible support structure was reasonable and applicable.
