Analysis of acoustic radiation of submerged damped cylindrical shell combined with thin shell theory and elasticity theory

摘要：

　　The acoustic radiation of submerged damped cylindrical shell is investigated by combining with thin shell theory and elasticity theory.The classical integral transform technique is used to derive the solutions of coupled equations.Numerical computations show the correctness of the proposed method,and also conclude the influence of thickness of inner shell and coated layer to acoustic radiation.The conclusions may be valuable to the application of damping material on noise and vibration control of underwater pipes.
