摘　　要：动力装置隔振技术是鱼雷振动与噪声控制的重要措施之一,该文基于对动力装置隔振圈的受力分析,用四端参数法建立了隔振系统振动传递数学模型,对振动传递损失进行了分析,同时探讨了隔振圈的几何结构、橡胶硬度和阻尼等参数对隔振特性的影响。分析结果表明,四端参数法适用于复杂结构隔振圈的隔振研究,而且能降低橡胶硬度,提高橡胶阻尼,增加橡胶块长度,从而可明显提高隔振效果。Vibration isolation of torpedo power is very important to control vibration and noise of torpedo. By means of four - end parameter analysis method, a simplified vibration transfer model of isolator is established based on the force analysis of the vibration isolation ring of torpedo power. The vibration transfer loss is analyzed, and the influence factors such as the ring structure, rubber hardness and rubber damping on vibration transfer are also discussed. The conclusion indicates that the four-end parameter analysis method is suitable to the vibration isolation analysis of the complicated structure of vibration isolation ring, and the vibration isolation can be obviously improved with this method by reducing rubber hardness, and increasing rubber damping and rubber length.
