Abstract

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.

使用矩法随机评估参数滚动加速度概率密度函数

摘要

集装箱船遭遇大横摇角和高加速度，集装箱损失仍然是一个问题。本研究提出了一种计算横滚角和货物横向加速度的概率密度函数（PDF）的方法。首先，利用期望的线性推导这些加速度的力矩值，并检验该方法的有效性。其次，提出了这些加速度的 PDF 形状，并使用获得的力矩值确定它们的系数。我们提出的方法可用于推导横滚角和货物横向加速度的 PDF。
