Damping Design for Shell Structure of Underwater Vehicles

摘要

摘要: 鱼雷壳体、潜艇外壳、自主式水下航行器(AUV)舱壁等薄壳结构的抗振保护和噪声控制是确保其可靠完成任务的重要指标, 而上述薄壳结构又是由不同几何尺寸的板壳结构组合而成。本文利用模态阻尼比的提取方法对阻尼夹层板壳进行有限元计算, 将阻尼减振结构应用到壳体设计上, 并对不同阻尼结构、材料、厚度以及分布位置等方面的减振效果进行了分析计算, 结果表明, 该方法在航行体壳体减振设计方面具有很好的应用前景。

Abstract: Anti-vibration protection and noise control of such cable-shell structures as torpedo′s and submarine′s shells, and cabin wall of autonomous underwater vehicle(AUV) are important to their purposes. The cable-shell structure is composed of different shell structures with different geometric dimensions. This paper performs finite element calculation of damping sandwich shells with the method of modal damping ratio extraction, applies damping anti-vibration structure to shell design, and analyzes anti-vibration effect of different damping structure, material, thickness and distribution location. The result shows that this method can facilitate anti-vibration design of vehicle cable-shells.
