摘　　要：军舰在海上作战过程中,其隐蔽性非常重要,而船舶的噪声性能直接决定了其隐蔽性。本文针对舰船运行过程中的线状谱噪声问题进行系统研究。结合混沌控制理论和非线性振动技术,设计舰船的隔振系统,并对该隔振系统建立函数模型。试验表明,基于混沌隔振技术的舰船降噪取得了良好的效果。The concealment of military ships is very important in the process of marine operations, and the noise performance of ships directly determines its concealment. In this paper, the problem of linear spectrum noise in ship operation is studied systematically. In this paper, based on chaos control theory and nonlinear vibration technology, a vibration isolation system is designed and a function model is established. Later experiments show that the ship noise reduction based on chaos vibration isolation technology has achieved good results.
