讨论了并列双柱圆柱体在均匀流场中的涡激振动。依据已发表的有关该课题的实验与理论资料,提出了一种关于并列双柱圆柱体在均匀流场中涡激振动的理论预报模型。将理论计算值与资料所提供的实验值进行比较后,发现理论值与实验值尚能吻合。为了验证理论预报模型的正确性,作了实验观察,发现理论预报的涡激振动现象与实验中所出现的吻合良好。为了更好地掌握双柱涡激振动的机理,进行了结果分析和讨论。 The vortex-induced vibration of parallel double cylinder in uniform flow field is discussed. Based on the published experimental and theoretical data about the subject, a theoretical prediction model of vortex-induced vibration in a homogeneous flow field is proposed. Comparing the theoretical calculation with the experiment data provided by the data, it is found that the theoretical value agrees well with the experimental data. In order to verify the correctness of the theoretical prediction model, experimental observations were made and it was found that the vortex-induced vibration of the theoretical prediction is in good agreement with that in the experiment. In order to better understand the mechanism of vortex induced by two columns, the results are analyzed and discussed.
