| Abstract: | 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. |
