摘要	An optimization design method for the bracket of a star sensor was proposed to overcome a larger acceleration response value (Root Mean Square(RMS)) under random excitation of a micro-satellite. The basic theory of random response of the star sensor at an installation point was described, and the structure modal and acceleration response sensitivity of the satellite structure were analyzed. By taking the minimum random response RMS value at the installation point as the target, and the nature frequency and volume fraction for the restraint, an optimized model for the bracket of the star sensor was established and the topological optimization was performed for the model. Finally, the engineering analysis was carried out on the optimized model by using MSC. PATRAN NASTRAN. The results show that the random response RMS value of the star sensor at the installation point has reduced more than 20%, the lightweight rate of the support structure has reached 50%. Furthermore, the bracket of star sensor was tested with a random vibration test platform. The results indicate that the relative error of the finite element analysis results and the experimental data is less than 15%, which shows that the designed performance parameters meet the design requirements and verifies the feasibility of the optimization method. 2016, Science Press.
