通过对管道振动试验数据的分析,选用威布尔分布的概率密度函数进行拟合,得到涡激升力的频谱表达式。通过管道振动的频响函数得到管道的振动位移的频谱图形,并与实测数据进行对比,结果表明：计算值与实验值吻合较好,中心频率基本相等,幅值稍有偏差。 Through the analysis of pipeline vibration test data, the probability density function of Weibull distribution is chosen to be fitted to obtain the spectral expression of vortex-induced lift force. Through the frequency response function of pipeline vibration, the spectrum of vibration displacement of the pipeline is obtained and compared with the measured data. The results show that the calculated values ​​agree well with the experimental values, the center frequencies are basically the same, and the amplitude is slightly deviated.
