不同浪向的不规则波作用下系泊船舶动态特性的差异

Difference in dynamic characteristics of moored vessels under the action of irregular waves from different wave directions

不同浪向的波浪对系泊船舶的影响,是港口规划设计中非常关心的问题。本文首先简要论述了用不规则波进行系泊船舶动态模型试验的必要性;然后,根据不同浪向的不规则波试验研究结果,阐述了横向浪、斜向浪、顺浪作用时,船舶六个分量运动及缆力、撞击力随波歹寸有效周期Ts的变化规律。

The influence of waves from different directions on moored ships is a problem attracting much concern in port planning and designing. In this paper, the author first briefly presents the necessity of carrying out irregular wave model tests for the dynamics of moored ships, and then, on the basis of the results of irregular wave tests in which waves were from different directions, the author elaborates the regularity of the changes of the 6 freedom motions, mooring force and impact force of ships with the effective periods of wave trains (Ts) when the ships are subjected to the action of transverse waves, oblique waves and parallel waves.
