| 摘 要： | 本文用建立传递函数的方法,通过入射波浪谱(方向谱)得出群墩上作用力谱及特征值。入射波浪频谱采用JONSWAP谱,方向分布函数为平方余弦函数。计算了2至4墩各种排列情况下群墩力系数。可供工程设计使用。对单墩单一方向频谱进行计算的实验资料的对比,符合良好。

| Abstract: | In this paper, by using the method of establishment a transfer function, the wave forces spectra on cylinders and the characteristics values are obtained from in incident wave spectra. The JONSWAP spcetra in used as a incident frequency spectra the Directional distribution function is square cosinusoidal funcation. The wave forces coeficients is two to four cylinders with different arrangment is computated wich can by used for engineering design. A comparison of computational and experimental results of single cylinder with frequency spectra is made and the agreement is satisfactory. |
