摘要
本文应用随机过程的线性系统理论,研究不规则风对船舶横摇运动的影响,将风速的不规则变化以Davenport,A.G.风能谱密度表示,并求船舶在不规则风中的横摇能谱密度,进而讨论横摇运动的统计特征值。
By means of the theory of linear system in stochastic processes, the effect on the rolling of ships by confused winds is studied. The Davenport' s spectrum of gustiness in high winds is used for the representation of the random variance of confused wines,and the rolling spectrum of ships in confused winds is obtained. Then the ship' s rolling statistical characteristic ralues are dealt with.
