摘要
统计能量分析法(SEA)被广泛用于在中高频段预测复杂结构的振动和噪声传递,文章综述了近40年来国内外统计能量分析法在船舶噪声预测中的应用,总结了确定船舶统计能量分析中的四个重要参数即子系统的模态密度、内损耗因子、耦合损耗因子和输入功率的计算或测量方法。
Statistical Energy Analysis （SEA） has been applied widely to predict vibration and noise transmission through complex structures at medium and high frequencies hands. Applications of SEA on ship noise control in recent forty years home and abroad are summarized. Calculation or measurement methods for determination of the subsystems＇ four important parameters, consisted of modal density, internal loss factor, coupling loss factor and input power in the ship statistical energy analysis are presented.
