Abstract

Abstract

To address the significant degradation in sound absorption performance of conventional cavity-type rubber coatings under high hydrostatic pressure, a pressure-resistant and sound-absorbing integrated coating with a high-transmission composite layer is proposed. Based on the finite element method, a numerical model considering hydrostatic pre-stress, moving mesh, and acoustic-structure coupled frequency-domain perturbation is established to investigate the sound transmission performance of the composite layer and the sound absorption characteristics of three cavity configurations under different static pressures. The results show that, under hydrostatic pressures of 0-9 MPa, both glass fiber reinforced plastic(GFRP) and carbon fiber reinforced plastic(CFRP) layers maintain high sound transmission coefficients with limited pressure sensitivity. The rectangular, petal-shaped, and conical cavity coatings with the high-transmission composite layer all achieve sound absorption coefficients generally above 0.7 in the 4-10 kHz range, with only slight variation under different pressures. The high-transmission composite layer effectively suppresses pressure-induced deformation of the cavity structure, thereby improving the stability of sound absorption performance under high-pressure conditions. This study provides a reference for the design of underwater sound-absorbing coatings in high-pressure environments.
