実験SEAによる直列結合した構造体への断面形状変更の影響に関する研究

抄録

This paper focuses on the transfer characteristics of the structure and describes the investigation of structural modifications aimed at vibration reduction during operation. Numerical analysis is being conducted to investigate a structure that lowers energy transmittance, namely, lowers coupling loss factor, by providing the vibration-reducing ribs for preventing vibration transmission to the evaluation element. We applied the proposed method to a handheld vacuum cleaner with three elements connected in series, and examined the effectiveness of the vibration reduction effect on the handle element by using experimental SEA.
