提出了一种利用平稳随机横摇响应预测单位虚拟质量转动惯量的波浪激励力矩时间序列的方法。估计的方差和自相关函数的激励进行比较，使用数值生成的数据。协议非常好。该方法也适用于使用两个船模获得的实验数据。预测的自相关函数的激励进行了比较的自相关函数的波高。该方法准确地预测了自相关函数的形式。该方法适合于在海上的船上使用而不中断船的使命。此分析结果可帮助规划最佳船舶路径。
A method is developed to predict the time series of the wave exciting moment per unit virtual mass moment of inertia using the stationary random roll response. The estimated variance and autocorrelation function of the excitation are compared with those obtained using numerically generated data. The agreement is excellent. The method was also applied to experimental data obtained using two ship models. The predicted autocorrelation function for the excitation was compared with the autocorrelation function of the wave height. The method predicts the form of the autocorrelation function accurately. The method lends itself to use aboard ships at sea without interrupting the mission of the ship. Results of this analysis can help in planning optimum ship routing.
