摘要
本文从能量分析的角度，通过计算振动的封闭圆柱壳的弹性变形能，以及加装 Ｂ Ｂ Ｄ（ Ｂｅａｎ Ｂａｇ Ｄａｍ ｐｅｒ）后 Ｂ Ｂ Ｄ 的总耗能量，对 Ｂ Ｂ Ｄ 控制封闭圆柱壳振动的阻尼进行了预估，通过试验验证计算结果与试验结果有很好的一致性。
In the paper, from the view point of energy analysis, on the basis of calculation of elastic deformation energy of vibrating closed cylindrical shell and energy consumption of BBD after it is installed on the shell, the damping of BBD controlling vibration of closed shell is predicted. Numerical result and testing result tally well with each other. It is proved that the damping prediction method offered in the paper is very useful in engineering practice.
