摘要
基于Chen有界域静止流体中棒束流致振动数学模型,给出了棒束稳定分析的数值方法。作为应用研究,分析了有界域轴向流动中棒束(4根)流致振动的特性及稳定性。
The mathematic models and the stability analysis method are established for analyzing flow induced vibration of rod bundles in bounded axial flow. As applications, the vibration characteristics and stability of a 4 rod system are studied. With the flow velocity incremental, the system experiences divergence instability and flutter instability. The existence of the axial flow induces the coupling of the movement of the rods. This coupling makes the very complicated vibration modes.
