摘　　要：在光机系统中,镜框材料的选择影响着面型质量。以实际项目为研究背景,采用6061、TC4和4J32这3种材料设计光机系统窗口镜框,并利用有限元方法对镜框组件进行热分析和静力学分析,得到其温度梯度和热力耦合后应力结果,以此评估窗口镜框的综合特性。研究表明:3种材料的镜框在太阳辐射强度800 W/m^(2)照射10 min的工况下,6061材料的镜框产生了7.4℃的最大温度梯度,高出其余两种材料约3℃;热力耦合分析中,TC4和4J32的面型RMS值均小于等于(1/30)λ(λ=632.8 nm),满足设计要求。In optical mechanical systems,the selection of frame materials affects the surface quality.Taking the actual project as the research background,the window frame of the optical and mechanical system is designed with 6061,TC4 and 4J32 materials,and the thermal analysis and Statics analysis of the frame components are carried out using the finite element method to obtain the temperature gradient and stress results after thermal mechanical coupling,by which the comprehensive characteristics of the window frame is evaluated.The research shows that the maximum temperature gradient of 7.4℃is produced by 6061 material when the frame of three materials is exposed to 800 W/m^(2)of solar Radiant intensity for 10 minutes,which is about 3℃higher than the other two materials.In thermal coupling analysis,the RMS of TC4 and 4J32 surface shapes is less than or equal to(1/30)λ(λ=632.8 nm),which meets design requirements.
