论文摘要
集装箱船会遇到较大的卷角和高加速度，并且容器损失仍然是一个问题。这项研究提出了一种计算滚动角和货物横向加速度的概率密度函数〜（PDF）的方法。首先，使用期望线性和该方法的有效性得出这些加速度的力矩值。其次，提出了这些加速度的PDF形状，并使用获得的矩值确定其系数。我们提出的方法可用于得出滚动角和货物横向加速度的PDF。
Container ships encounter large roll angles and high acceleration, and container loss remains a problem. This study proposes a method for calculating the probability density function~(PDF) of roll angular and cargo lateral accelerations. First, the moment values of these accelerations are derived using the linearity of expectation and the validity of this method is examined. Second, the PDF shapes of these accelerations are proposed and their coefficients are determined using the obtained moment values. Our proposed method can be used to derive the PDFs of roll angular and cargo lateral accelerations.
