Fem解析を用いた蛇腹形状による音圧低減効果の音響解析

Key Points

• The research aims to visualize the movement of air particles and sound pressure with bellows shapes, clarifying their sound reduction mechanism.
• Used Finite Element Method (FEM) analysis to model sound pressure effects in rectangular rooms.
• Visualized air particle movements and sound pressure in relation to bellows shapes.
• Conducted sensitivity analysis on parameters like height and depth of bellows.
• Confirmed sound pressure reduction due to resonance effects within and outside the bellows structure.
• Identified significant parameters affecting the sound pressure reduction mechanism.
