In order to analyze the high-frequency vibration response of an underwater vehicle under unit force excitation and reduce its noise, we established a model based on statistical energy analysis (SEA) and developed a method for the analysis of the transmission path, whose accuracy was verified by comparison of experimental and simulation results. Vibration and noise characteristics of the vehicle are optimized by adjusting the thickness of some key components, revealing that vibration response of the vehicle is sensitive to subtle structural adjustments in the critical frequency band. As a result, noise reduction of the vehicle can be achieved by optimizing the thickness of its substructures. Our work offers a procedure for the structural optimization of underwater vehicles, assisting their low-noise development.
