  • In this paper, the structure design and thermal stability of the light and small reflector component of laser communication and ranging integration satellite link load are studied. Optimization design of flexible support mechanism of reflector component is carried out. According to the working conditions and in-orbit thermal environment, the optical component integration analysis of the mirror assembly is carried out to evaluate the on-track thermal stability of the opto-mechanical structure. The analysis results show that the surface precision of the mirror with double-layer circular arc slot flexible support structure can be reached at λ/72 after temperature deflection, the fundamental frequency mode is 417.93Hz, meeting the requirements of the index. Furthermore, the dynamic analysis of the mirror assembly is carried out, the results of random vibration analysis show that the root mean square of the acceleration response of the mirror is 11arms and meet the 3σ criterion. Finally, a 0.2g sine sweep test proves that the relative error of the modal analysis is 2.24%, the experimental result show that the analysis results are basically accurate and reliable, that is, flexible support design is reliable to meet the requirements of the use.
