拘束フレームと粘弾性層からなる制振デバイスによるビードパネルの制振解析と音響放射解析

抄録

In this study, we propose a new vibration control device consisting of a constraining frame and a viscoelastic layer to realize high vibration control performance. The proposed new vibration control device consists of a viscoelastic gel partially sandwiched between a highly rigid constraining layer with a box cross section and a frame member. It converts vibration energy into thermal energy through damping. In this study, a bead panel with a vibration control device consisting of a constraining frame and a viscoelastic layer is modeled and analyzed numerically by FEM, and the changes in vibration reduction characteristics and sound radiation characteristics are obtained using the MSE method．
