Analysis of vibration and sound radiation from finite stiffened plates covered with damping layer
摘要
Abstract
The vibration and sound radiation in air and water of finite stiffened plate under single frequency excitation and white noise excitation were analyzed respectively by modal experience, and the corresponding numerical solution for the model was presented. It shows that the peak value of vibration velocity moves left when coated with damping layer. The effect of damping layer on sound reduction and vibration rejection was proved to be well in general, but not so obviously at low frequency narrow, even disappear at some frequency point. A numerical analysis was also developed to prove a good effect of damping layer on sound reduction and vibration rejection.关键词
