| 摘 要： | 对于轴对称物体,提出了一个三阶波浪力的全绕射计算方法,自由水面上的三阶强迫项采用向外递推的方法加以计算。本方法已在计算机上实现。对于均匀圆柱问题,本方法计算结果与Malenica的半解析解吻合良好。本方法还被用于计算圆柱上的三阶波浪力矩,结果发现在低频区三阶波浪力矩具有很大的量值。

| Abstract: | A third-order diffraction theory for the third-order wave loads is proposed. The method has been implemented for bodies of revolution with vertical axes, but the theory is also available for arbitrary bodies. A numerical examination is made to validate the numerical code by comparing the third-order force on a uniform cylinder. The method has also been used to compute the third-order moments. |
