航天光学遥感器指向镜的稳定性对提高图像几何精度起着至关重要的作用,而指向镜的胶粘剂决定了指向镜的指向稳定性,首先分析了遥感器对指向镜高稳定性指向的使用要求,然后对航天中常用的三种胶粘剂进行了全面对比,结合指向镜的实际使用要求,选择了HY914和SE-14-80两种胶粘剂进行粘接应力比较,通过为这两种胶粘剂制定合理的固化工艺路线,在相同的条件下进行了胶粘前后指向稳定性试验验证,试验结果表明,采用特定的固化工艺,使用SE-14-80粘接剂的指向镜粘接前后指向偏差约为1″,是航天光学遥感器指向镜胶粘剂的最优选择。鉴于其优异的粘接性能,此胶粘剂已在某在研项目中应用。
The stability of pointing mirror of space optical remote sensor plays an important role in improving the geometric accuracy of the image. The adhesive of the pointing mirror determines the pointing stability of the pointing mirror. Firstly, the remote sensor’s use of high pointing stability of the pointing mirror is analyzed Requirements, and then the three commonly used in aerospace adhesives a comprehensive comparison, combined with the actual use of the mirror requirements, select the HY914 and SE-14-80 adhesive two kinds of adhesive stress comparison, through the formulation of these two adhesives reasonable Of the curing process route under the same conditions before and after the adhesion stability test to verify the test results show that the use of a specific curing process using SE-14-80 adhesive before and after the point of the lens bonding deviation is about 1 "is the best choice for aerospace optical sensor pointing mirror adhesive, which has been used in some research projects due to its excellent adhesive properties.
