摘要
本文介绍了柔性约束颗粒冲击阻尼技术及其减振机理;并将该技术应用于薄壁密闭腔体壁板振动和内部噪声的控制。实验证明,该技术结构简便、控制频带宽、减振降噪效果显著。
The Bean Bag Damping (BBD) technique and its mechanism of impact damping are presented in this paper, and this technique is applied to the control of wall vibration and interior noise in a thin-walled enclosed cavity. The results of the experiment show that the BBD technique is simple and convenient, its controlling frequence band is wide, and the effect of damping and noise reduction is notable.
