| Abstract: | For the purpose of cabin noise reduction, in this paper, the plane panel's vibrational characteristics before and after equipped with dynamic vibration absorbers are analyzed, the formulae for calculating the vibration and noise reduction of the plane panel with dynamic vibration absorbers are given, and the dynamic vibration absorber's parameters are discussed. On the basis of this, a kind of dynamic vibration absorber is designed and experiments are carried out. The agreement between the estimated and measured values is in most cases very good. It shows that the dynamic vibration absorber has great advantages in plane panel's vibration and noise reduction. |
