PAFEC-VibroAcoustics - Underwater Acoustics

For structures vibrating underwater a fully coupled vibroacoustic solution is almost always essential. The density of fluid ensures that the pressure field generated by the vibrating surface applies significant loading to the structure and it vibrates differently in fluid from in vacuo. Generally speaking modes/resonances will occur at lower frequencies due to an added mass effect. Radiation damping generally reduces the amplitude at resonance.

Application Areas

• SONAR transducer design
• array design
• SONAR domes
• radiation from submerged structures
• scattering from submerged structures
• tile design
