Abstract

Abstract

To investigate the vibration transmission characteristics of the underwater shaft-cone-cylinder double-layer shell structure, a fluid-solid coupling finite element model was constructed based on the HyperMesh-ANSYS co-simulation platform, so as to simulate the full-process dynamic behavior of shaft excitation, bearing transmission, shell, and liquid coupling. The effects of interhull fluid density, bearing stiffness, and internal and external fluids of the shell on structural vibration transfer were systematically analyzed. The results show that the interhull liquid reduces the resonance frequency of the system through the added mass effect and enhances the sound pressure level through the fluid-solid coupling effect. The increase in bearing stiffness can suppress the shaft system vibration but excites the high-frequency resonance of the shell. In the low-frequency band, the strong continuity of the interhull liquid enhances the vibration transmission between the double-layer shells, while the additional mass and damping effects block the vibration transmission in the high-frequency band. This study reveals the vibration transfer effect of the underwater shaft-cone-cylinder double-layer shell model and provides theoretical support for the acoustic vibration design and vibration and noise reduction optimization of undersea vehicles.
