Finite Element Parametric Acoustic Modeling and Analysis of Ship Floating Cabins

Abstract:

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 and comparative analysis of a low-order vibration frequency of the cabin under different fire ratings. Acoustic calculation program of the fluid-structure interaction is used to analyze harmonic sound field and verify the impact of different thickness fireproof rockwools on the cabin acoustic performance. Parametric Design and Finite Element Analysis are combined to achieve the adjustment of the structural parameters of the complex models, automatically generate solid models and complete finite element analysis, which is important for the optimization of the acoustic design of the ship cabins.
