舰艇纵倾平衡系统水锤冲击激振特性分析
Analysis of Vibration Characteristics Induced by Water Hammer of Ship’s Longitudinal Inclination and Balance System

舰艇水下航行过程中需频繁进行纵倾平衡水舱的移水操作，经常出现水锤现象，从而诱发系统高强度瞬态振动及瞬态噪声，通过FLOWMASTER输出瞬态载荷力，并在CAESAR II中建立纵倾移水系统模型，进行时间历程分析计算。同时，计算分析了支撑高度、支撑刚度、固定方式和支撑间隔对舰艇纵倾平衡系统振动的影响，为后续管路系统的三维设计提供支撑。
In the process of underwater navigation, it is necessary to move water in the longitudinal inclina-tion and balance tank frequently. Water hammer often occurs, which induces high-intensity tran-sient vibration and transient noise of the system. The transient load force is output through Flow Master, and the model of water transfer system is established in CAESAR II for time history analysis and calculation. At the same time, the influence of support height, support stiffness, fixing mode and support spacing on the vibration of longitudinal inclination and balance system is calculated and analyzed, which provides support for the subsequent three-dimensional design of pipeline system.
