Study on vibration characteristics of badminton racket embedded in acoustic black hole structure

According to the principle of acoustic black hole effect, a badminton racket design method embedded one-dimensional structure was proposed. Based on finite element simulation analysis, broadband vibration attenuation characteristics were studied. The results show that this can not only ensure light quality system, but also achieve good reduction effect. In absence damping, small truncation make reflection coefficient increase rapidly, and larger truncation, worse suppression combination form damping material shows obvious formant in wide band range, thickness layer closer location tip, more
