摘要
为进一步降低鱼雷动力系统噪声水平,文章对鱼雷动力系统的振动控制技术进行论述,分析了结构动力学设计方法、整机隔振技术、液流管路振动抑制技术以及装配工艺技术在鱼雷动力系统振动控制工程上的应用,指出了鱼雷动力系统振动控制领域的发展方向:设计层面,从以往解决结构强度、刚度为主的设计方法转换为以结构动力学为牵引,以实现低噪声、大推比的动力系统为目标的设计方法;隔振层面,从以往的单点局部隔振向整机隔振与液流管路振动抑制方向发展;装配调试层面,装配工艺控制日益成为影响振动性能的重要因素。文章所述内容可为研制具有较低噪声水平的鱼雷动力系统提供理论参考。
To further reduce noise level of torpedo power system,the vibration control technologies of the torpedo power system are discussed in this paper,the applications of the structural dynamics design method,the vibration isolation technology of the whole machine,the vibration suppression technology of fluid pipeline,and the assembly technique in the vibration control engineering of torpedo power system are analyzed.Moreover,the development directions of the torpedo power system vibration control field are pointed out as follows:1)at design aspect,the previous design methods mainly for solving the structural strength and stiffness should be transformed into the design method for taking structural dynamics as traction to achieve low noise and high thrust ratio of torpedo power system;2)at vibration isolation aspect,the previous single-point partial vibration isolation should be transformed into the vibration isolation of whole machine and the vibration suppression of the fluid pipeline;and 3)at assembly aspect,the assembly process control has increasingly become an important factor affecting the vibration performance.This study may provide theoretical reference for the development of Torpedo power system with low noise level.
