The responding nonlinearshipmotion mathematical model is constructed on the basis of the state space ship motion mathematical model by the systematic method of input-output information.
The results indicate that the new path integration method is efficient in the studying the probability distribution of shipnonlinear roll motion from the numerical simulation results.
数值模拟的结果表明新的路径积分法对研究船舶非线性横摇运动概率密度分布是十分有效的。
