The work includes the development of parametric calculation module program based on APDL, the completion of 3D acoustic modeling of a ship floating cabin, the selection of constraints according to the actual work situations, the finite element modal analysis of the overall cabin in the ANSYS environment as well as the comparative analysis of a loworder vibration frequency of the cabin under different fire ratings. Acoustic calculation program of the fluidstructure interaction is developed to analyze harmonic sound field and verify the impact of fireproof rockwools with different thickness on the cabin acoustic performance. Parametric design and finite element analysis are combined together to adjust the structural parameters of the complex models, generate solid models automatically and complete finite element analysis, which is important for optimizing the acoustic design of the ship cabins.
