Structural optimization study of a satellite integrated controller bracket under random vibration

This paper investigates the vibration problem of a satellite controller bracket that is subjected to random excitation. We developed a parametric model for the bracket’s structure and optimized its dimensions using Abaqus random vibration analysis and Isight optimization algorithm. The optimized structure underwent bearing capacity analysis and random vibration analysis. On the premise that the structure satisfies the strength, stiffness, and frequency conditions, the power amplification factor is reduced and the structural mass is minimised, which effectively improves the vibration damping performance, leading to a more rational structural design.
