FEMとSEAを併用した騒音解析手法の検討

(円筒モデルの固体振動解析)

This paper presents a structure-borne vibration analysis method of cylindrical structure using FEM model and Statistical Energy Analysis (SEA) method. The coefficient which contributes to reduce panel vibration using calculated Internal Loss Factor (ILF), Coupling Loss Factor (CLF) of SEA model was picked out. And we drafted the structure to which vibration of the panel can be reduced, and the effect was inspected by FEM analysis and FEM-SEA analysis. The drafted structure was contrived from the point of view to which input power is reduced, and it'll be expected to inspect the effect by experiment.
