内容記述
This paper presents a structure model construction for statistical energy analysis (SEA) using FEM. Identifying SEA parameter regardless of the excitation method is demanded effectively. The proposed method is based on a combination of SEA and vibration response by random vibration analysis. This method is effective on an analytical cost performance for base excitation compared with the conventional force excitation method that is called rain-on-the-roof-excitation. In this study, the proposal method is validated through the two types of model, (i) simple flat plate consisting of one subsystem, and (ii) an L plate consisting of two subsystems. As a result, the method is shown to work quantitatively well to the internal loss factors and qualitatively well to the coupling loss factors.
