Vibration and Self-noise Characteristics of Composite Compartments for Underwater Acoustic Transducers
摘要
Abstract
The design of a component compartment for accommodating underwater acoustic transducers needs to consider its vibration transmission characteristics and inherent noise performance,and high-precision numerical prediction of its vibro-acoustic performance is the key technical support for preliminary efficient design of vibration and noise reduction.Considering the strong coupling between the composite structure and the water medium,a vibro-acoustic coupling model was established for the compartment housing sidewall acoustic devices and damping rubber composite structures.Numerical analysis was conducted to explore the inherent properties of the submerged composite structure,the vibration acceleration and self-noise power response under different damping rubber hole diameters.The effect of submerged depths on vibro-acoustic performance was also discussed.Rubber configurations with low vibration transmission and low self-noise were then determined.The test of acceleration sensitivity for hydrophones also verified the employed dynamic numerical model and method.This study provides a practical example for predicting coupled vibration noise and selecting noise reduction structures for underwater acoustic devices and their auxiliary structures.关键词
