摘　　要：风帆助航技术为船舶利用可再生能源提供了途径,但随着横摇的幅度加大,导致船舶倾覆的概率也增大。文章采用数值分析的方法对风帆助航船舶的非线性横摇方程进行分析求解,对有风帆助航与无风帆助航船在风浪作用下产生倾覆的概率作了比较,为采用风帆助航技术的远洋船舶在符合初稳性和气象衡准稳性条件下的横摇倾覆防范提供研究思路。Sailing ship technology provides some methods to use regenerated energy, however, with the increasing extent of rolling, it also causes the probability of capsize to increase.In this paper, the method of numerical analysis was used to analyze the nonlinear roll equation of sailing ship,and compare the probability of sailing ship roll with non sailing ship roll, a research approach of taking safety precautions is provided for ocean-going sailing ships to prevent capsizing under the condition of the early stability and weather stability criterion.
