摘要
为确定海运时船舶及其上所载货物所受的随机波浪载荷,以保证船舶和货物在海运中的安全性,提出将随机过程理论运用于不规则海浪的模拟过程,确定了随机海浪的数值建模方法,创造性地结合谱分析方法进行船舶运动研究,并通过数值计算方法模得出特定条件下船舶摇荡运动的功率谱密度分布.
To determine the random wave loads of the ship and its cargo and thus ensure their safety, the stochastic process theory is applied to the simulation of irregular waves. The power spectrum density function of each DOF motion of the ship based on the established numerical modeling method for random wave spectrum is derived. The power spectrum density distribution of swaying motion of ship is also calculated under specific conditions.
