摘　　要：应用随机稳性理论 ,研究建立舰船稳性监测的数学模型。通过实时数值分析和自适应识别技术处理舰船横摇运动的水动力系数 ,提出舰船动稳性衡准指标 ,进行舰船在风浪中稳性的实时计算及预报研究。通过算例 ,说明应用随机风浪中航行舰船的动稳性预报方法 。Some mathematical models, which are about ship's stability monitoring are discussed and built by applying the stochastic stability theory. By real time analyzing and self adapting value analyzing, hydrodynamic coefficient for ship's rolling is dealt with.The dynamic stability norms are put forth, and therefore the real time calculation and prediction for ships in wave and wind have been made.By calculated examples,it is proved that by dynamic stability prediction method applied to ships in stochastic wind and wave,a ship's stability reserves and safety performances can be estimated effectively
