本文从横摇运动微分方程出发,结合随机微分方程理论,讨论了船舶在横对随机波时的倾覆概率问题.可以看出关于船舶在随机波上倾覆概率问题目前提出的几种方法间的联系.最后用Fokker-Planck方程解出了随时间演变的概率分布函数,分析了倾覆问题.

This paper deals with the problem of probability of a ship capsize in random beam waves. By us-ing the method of nonlinear oscillation together with the theory of stochastic differential equation, some prop-erties of the probability distribution of ship rolling were investigated. Several methods about this problempublished recently were commented. Some concluding remarks were presented.
