Test experiment of loss characteristics of composite sandwich panel is carried out. Loss factor of composite sandwich panel is obtained
and it is recognized the basic parameter input for numerical calculation.And use acoustical-structure coupling finite element analysis method
underwater vibration acoustic radiation characteristics of underwater vehicle superstructure with composite sandwich panel is analyzed. On this basis
influence rule of structure thickness parameters on vibration and acoustic radiation characteristics of underwater vehicle superstructure is studied
acoustics optimization design schemes of composite superstructure is proposed
which aims to provide a reference for acoustics design of superstructure.
