板端部に部分的波動ブラックホールを付与したL字パネル構造の制振応答解析

抄録

This paper describes hybrid vibration analysis using Statistical Energy Analysis（SEA）and FEM for two panels connected in L-shape with an acoustic black hole having a damping layer. The size of acoustic black hole in the L-shaped panel structure is changed. We focused on effects of changing the size of the acoustic black hole in the L-shaped panel structure on wave transmission characteristics between the two panels and damping effects due to the acoustic black hole.
