As spacecrafts are growing larger, the vibration control strategy has become one of the critical technologies of wide concern. Traditional vibration reduction methods have many limitations, especially for the low frequency vibration problem of large-scale thin-film structures. To solve this problem, a novel structure of the mechanical metamaterial for compromising low-and medium-frequency vibration is presented based on the local resonance principle. Changing the unit structure of metamaterials can significantly adjust the position and width of the acoustic band gap. The lowest frequency of this metamaterial structure sits below 100 Hz through passively damping vibration, which will massively contribute to vibration control of spacecraft in the future.
