摘　　要：波浪中船舶破损稳性是影响船舶安全航行的重要性能之一.在实际航行中,希望能通过稍微改变当前航行状态来规避倾覆.论文基于前期建立的破损船舶波浪稳性预报方法,选取ITTC破损稳性研究用标准模型,研究不同波浪工况下破损船舶运动的安全边界,并分析了横荡、速度等因素对安全边界的影响.研究表明,论文采用的数值模拟方法可以很好地预报破损船舶波浪中的运动.横荡对倾覆的临界状态有影响,适当提高速度可以减缓倾覆的发生.Stability of a damaged ship will affect its safe navigation in waves.Based on the classical potential method,the research on capsizing characteristics and influencing factors of damaged ships in waves is carried out.The ITTC benchmarked model for the stability of damaged ship is selected.Reliability of the numerical simulation method used in this paper is verified by the existing model test,and safety boundaries of damaged ships under different wave conditions are studied.Influence of sway and speed on the safety boundary is analyzed.It is shown that the numerical method can well predict the motion of damaged ship in waves,and the sway has an impact on the critical state of capsizing.Appropriate increase in ship speed can slow down the occurrence of capsizing.
