Axial Vibration Characteristics of Piecewise Large Space Truss Structures
International Journal of Aerospace EngineeringLarge space truss structures (LSTS) are essential load-bearing components in many spacecraft. Owing to their large size, lightweight design, and high flexibility, they inherently exhibit very low natural frequencies and small damping ratios, making them ...
