| 摘要： | Predicting the wave exciting forces on a vessel typically involves two separate steps; determining a design wave at the location of interest, and then using a linear description of this wave to determine wave forces on a vessel. A method to directly determine the wave exciting forces on a vessel from a wave model would therefore be a very useful tool. This study reports the development, implementation and verification of such a program. The wave model is a non-linear Boussinesq-type 2D model. In determining the wave exciting forces directly from this model, it was desirable to include the non-linear behaviour from the wave model in the determination of the wave forces, as particularly the lower frequency harmonics can have a significant influence on the response of a moored vessel. The conclusion of the study is that the developed program gives a good approximation of the wave exciting forces on a vessel from a non-linear wave field, including the influence of higher and lower order harmonics in the determination of the wave forces. |
