| 摘 要： | 多冲击体阻尼（下文简称ＢＢＤ）是结构振动、噪声控制中的一项新技术。本文基于它的作用机理和机械导纳与弹性结构动力学理论，推导了三种不同ＢＢＤ板结构振动功率流的解析表达式。并进行了数值计算，给出了测量验证结果。最后定量分析了ＢＢＤ对板结构功率流的影响。

| Abstract: | Bean bag damping is a new technique for vibration and noise control.Based on its characteristics,mechanical mobility and structural dynamics,some analytical formulae for three different plate assemblies with BBD are derived.There is a good agreement among those results of computation using these formulae and those obtained by measuring the power flow in the structures.Finally,a discussion about the effect BBD on the power flow in the structurps is given in this paper. |
