摘要	To optimize solar spectroradiometers on satellites, a spatial turntable is designed according to performance indexes; finite element analysis is conducted and the properties of the prototype are tested. First, various articles were consulted to determine the fundamental structure of the turntable, and the azimuthal structure was selected. By researching the properties of different materials, M55J carbon fiber-which uses TC4 inserts for connection-was chosen as the main material for the turntable. The three main parts of the turntable are designed based on topological results and engineering experience; thus, a turntable frame with a size of 966 mm 400 mm 730 mm and mass of 27.3 kg is designed. Next, simulation analysis is carried out, from which the natural frequency of the entire turntable is established as 58 Hz. This implies that the strength and stiffness of the turntable fulfill the optimization criteria. Finally, resistance and thermal vacuum tests are conducted on the prototype. Test results showed that the natural frequency of the turntable was 53 Hz and the variation of the turntable's natural frequency was within 2% (sinusoidal vibration) and 4% (random vibration). Furthermore, we observed that the turntable functioned normally in a vacuum. Accordingly, the proposed design is tenable. 2021, Science Press. All right reserved.
