摘要

通过实验研究了高雷诺数下串列粗糙三圆柱的流致振动，分析与探讨了刚度、间距比对各个圆柱振幅响应、频率响应、位移频谱的影响，并与串列粗糙双圆柱的结果进行对比，揭示了干扰圆柱数量的增加对受扰圆柱流致振动的影响规律。研究结果表明：在初始分支，上游圆柱对下游圆柱有强烈的屏蔽作用，而在上端分支，出现下游圆柱振幅超过上游圆柱的现象；在上端分支和过渡区域，低刚度条件下，下游圆柱干扰数量的增加可以明显降低上游圆柱的振动频率；在涡激振动区域，下游干扰圆柱数量的增加几乎不影响上游圆柱的振幅；在驰振区域，上游圆柱干扰数量的增加降低了下游圆柱的振幅，并随着刚度的增加对下游圆柱振幅的降低程度下降；间距比对串列粗糙三圆柱的流致振动响应具有显著影响。

Abstract

Flow-induced vibration (FIV) of three roughness cylinders arranged in tandem is investigated at high Reynolds number. The influence of the spring stiffness and the spacing ratio on amplitude responses, frequency responses and frequency spectrums of displacement responses is analyzed and discussed. Meanwhile, comparison to the experimental results of two tandem roughness cylinders reveals the influence law of the number of the interference cylinder for FIV of the disturbed cylinder. The results show that in the initial branch, the shielding effect of the upstream cylinder on the downstream cylinder is vigorous, whereas in the upper branch, the phenomenon that the amplitude of the downstream cylinder is higher than that of the upstream cylinder appears. In the upper branch and the transition region, increasing the number of the downstream interference cylinder is able to decrease the oscillation frequency of the upstream cylinder. In the vortex-induced vibration region, the increase in the number of downstream interference cylinder scarcely affects the amplitude of the upstream cylinder. In the galloping region, the increase in the number of upstream interference cylinder tends to reduce the amplitude of the downstream cylinder, and this effect becomes weaker with increasing stiffness. The influence of the spacing ratio on the FIV of three tandem roughness cylinders is obvious.
