The prediction of structure-borne noise transmission in large welded ship structures is required, in order to design maritime vessels with greater ship power and reduced weight, without increasing the noise levels. The aim of this project is to develop a hybrid approach for structural dynamic analyses using an analytical waveguide method and Statistical Energy Analysis. The theoretical estimation and associated experimental measurement of the SEA parameters (modal density, coupling and internal loss factors) form the basis for the hybrid approach. The outcomes will result in improved predictive techniques for dynamic analyses of large complex resonant structures.

为了在不增加噪声水平的前提下设计出更大功率、更轻量化的船舶，需要对大型焊接船舶结构的结构噪声传递进行预测。该项目的目的是开发一种混合方法，用于结构动态分析，使用分析波导方法和统计能量分析。SEA参数（模态密度、耦合和内部损耗因子）的理论估计和相关的实验测量构成了混合方法的基础。研究结果将有助于改进大型复杂共振结构动力分析的预测技术。
