摘　　要：空间光学敏感器是航天器的重要组成部分,其在极端空间环境下可靠工作是空间活动和任务正常开展的保障。空间光学敏感器的核心在于光学系统的制造,目前空间光学敏感器最普遍采用的是中小口径透射式光学系统,这要求各光学元件之间进行精密的装配制造。与机械紧固件连接方式相比,胶粘方式在中小口径透射式光学系统制造中更具潜力,然而胶粘方式在面向航天应用的光学敏感器光学系统制造中鲜有提及。系统研究了面向空间光学敏感器光学系统的透射镜组胶粘技术,通过应力仿真与面形分析确定了XM31作为下层胶粘剂、DP460作为上层胶粘剂的用胶组合,通过L_(9)(3^(4))正交试验及极差/方差分析确定了包边后面形大小的主要影响因素是包边材料和下层涂胶面积,通过热真空、温度循环、力学环境适应性试验等空间环境地面模拟实验评估了该技术的可靠性,最终确定了最优胶粘技术参数。本工作对后续空间光学敏感器透射镜组装配技术研究有很强的指导意义。Space optical sensors are very important parts of the spacecraft,and their reliable operation in the extreme space environment is the guarantee for the normal conduct of space activities and missions.The core of the space optical sensor lies in the manufacture of the optical system,and the current space optical sensor most commonly adopts a small and medium-aperture transmissive optical system,which requires precise assembly of the optical components.Compared with the connection method of mechanical fasteners,the adhesive method has more potential in the manufacture of small and medium-aperture transmissive optical systems;however,the adhesive method is rarely mentioned in the manufacture of optical lens systems for aerospace.In this work,the adhesive technology of the transmissive lens group for the optical system of the space optical sensor was systematically studied,the adhesive combination of XM31 as the lower layer adhesive and DP460 as the upper layer adhesive is determined through stress simulation and surface shape analysis,and the main factors influencing the shape size after the hemming are determined by L_(9)(3^(4))orthogonal test and range/variance analysis,and the reliability of the technology is evaluated by the space environment ground simulation experiment including thermal vacuum,temperature cycling,mechanical environment adaptability test,and the optimal adhesive technical parameters are finally determined.This research provides strong guidance for the adhesive technology of the transmission mirror group of space optical sensors in the future.
