On the basis of characteristics of optical system of three-mirror off-axis, with the method of topology optimization, the mirrors' support structure and the frame structure which is a truss structure of the optical system were designed and investigated, the lightweight of the support structure and the truss structure are important, the structure optimization design of the system was completed, which quality is very light, by means of the finite element analysis techniques, we know that the shape error variation RMS and PV of optical mirror which are important indexes of image quality. The modal analysis and dynamic simulation calculation were carried out and the response character of the structure under dynamic environment was solved. Finally, the correctness of the finite element analysis results and the rationality of the design are validated by environmental testing. the analysis and test results indicate that the PV and RMS meet the design indexunder the comprehensive influence of gravity and thermal load which is in the control range, the overall structure have a high enough dynamic stiffness and reasonable distribution of modal, and the dynamic response of Space Remote Sensor was within the allowable range, which meet the use requirement.
