A semi-active vibration reduction method based on internal resonance is researched to solve nonlinear vibration problems of large flexible antennas. By adjusting the parameters of the vibration absorber, the fourth-order vibration mode of the large-space antenna and the vibration mode of the vibration absorber form 2:1 internal resonance, and the energy channel between them is established. The existence of energy interaction and effectiveness of vibration absorber are verified by experiments.
