本文详细地讨论了在有自由液面的情况下，如何有效地描述船舶的横摇运动。可用的数学模型与集中参数的实施和比较与比例模型实验。关键点是通过使用一个高效的参数识别技术证明。最后给出了一个具有良好仿真能力的模型。所提出的数学模型很好地拟合了实验数据，需要估计一组减少的参数。该方法在当前破损船舶行为研究的框架中具有重要意义。
In this paper, the possibility of obtaining an efficient description of the roll motion of a ship with liquids with free surface on board is discussed in detail. Available mathematical models with concentrated parameters are implemented and compared with scale model experiments. Critical points are evidenced by using a high efficiency Parameter Identification Technique. Finally a model with good simulation capability is presented. The proposed mathematical model fits well the experimental data requiting the estimation of a reduced set of parameters. The method appears of great interest in the frame of current research on the damaged ship behaviour.
