Study on Vibration and Acoustic Radiation Characteristics of Composite Material Superstructures of Underwater Vehicles

[摘要] Composite materials have been widely used in underwater ships for advantages of high specific strength, excellent acoustic performance and well designability. As an important indicator to measure combat effectiveness and vitality of underwater ships, structural radiation noise is the main target of acoustic detection weapons and the main factor that interferes with sonars. Underwater vibration and acoustic radiation characteristics of superstructure using composite sandwich panels directly affects the acoustic performance of underwater vehicles and the comfort and safety of personnel, therefore, research on vibration and acoustic radiation characteristics of underwater vehicle superstructure with composite material has important theoretical value and engineering prospect.
