Key Points

  • The research aims to analyze the vibration damping characteristics of L-shaped panels featuring crater-type acoustic black holes.
  • Hybrid vibration analysis utilizing Statistical Energy Analysis (SEA) and Finite Element Method (FEM).
  • Comparison of two L-shaped panels with and without crater-type black holes.
  • Evaluation of the impact of damping layer area on wave propagation.
  • Validation of the proposed SEA method for L-shaped panel vibration analysis.
  • Improved wave propagation characteristics observed with the introduction of the crater-type black hole.
  • Enhanced damping effects correlated with varying areas of damping layers.

Abstract

This paper describes hybrid vibration analysis using Statistical Energy Analysis（SEA）and FEM for two panels connected in L-shape with a crater-type acoustic black hole having a damping layer. We focused on the validation of the proposed SEA method and discuss the effects on the wave propagation characteristics between two panels in an L-shaped panel structure and effects of area of damping layers when the L-shaped panel structure was given a cratered black hole with a residual plate thickness.
