Estimation procedure on parameters of ship motions in parametric rolling based on time series analysis

本文构建了基于时间序列分析的船舶参数滚动过程中阻尼系数、固有频率等运动参数的估计方法。此外，利用船舶运动的估计参数，提出了安全判断指标。通过时间序列模型实验验证了该方法的有效性。机载实验也被进行。然而，我们无法观察到参数滚动现象。

In this study, the estimation procedure on parameters of ship motions such as the damping coefficient, the natural frequency and so on in parametric rolling based on time series analysis is constructed. Moreover, by using the estimated parameter of ship motions, the safety judgment index is proposed. The effectiveness of this is confirmed by using the time series of model experiments. Onboard experiments are also carried out. However, we were not able to observe the parametric rolling phenomenon.
