摘要: 浮筏隔振系统作为现代舰船设备常用的振动控制手段，是隔振降噪的一种重要技术，而功率流是评价隔振效果的有效方法。本文以功率流理论为基础，建立了柔性浮筏隔振系统的有限元模型，对浮筏隔振系统的隔振效果进行研究，揭示浮筏隔振系统振动能量传递的可视化路径；研究了浮筏隔振系统中隔振器各参数包括隔振器刚度、隔振器阻尼、设备质量等对系统隔振效果的影响。结果表明有限元功率流的分析方法可为浮筏隔振系统的结构设计及安全运行提供依据。
Abstract: As a common vibration control method for modern ship equipment, the floating raft vibration iso-lation system is an important technology for vibration isolation and noise reduction, and power flow is an effective method to evaluate the vibration isolation effect. Based on the power flow theory, the finite element model of the flexible floating raft vibration isolation system is established. The vibration isolation effect of the floating raft vibration isolation system is studied, and the visualization path of vibration energy transmission of the floating raft vibration isolation system is revealed. The effects of isolator parameters including isolator stiffness, isolator damping and equipment mass on the isolation effect of floating raft vibration isolation system are studied. The results show that the finite element power flow analysis method can provide a basis for the structural design and safe operation of floating raft vibration isolation system.
