| 抄録(英) | Transmission Loss is a key metric for automotive components such as dash panels. While curved panel acoustics are well studied, panels with acoustic treatments receive less attention. Classical FEM and SEA methods are limited by cost and assumptions, and TMM applies mainly to homogenized geometries. Deterministic simulations combining FEM for structure, poroelastic modeling for treatments, and BEM for sound propagation offer greater accuracy. To extend frequency range and enable SEA integration, computation time must be reduced. This paper introduces a DMP-SMP parallel approach for FE-BEM-PEM workflows on trimmed dash panels and compares bare structures using an accelerated H-Matrix BEM solver. 翻訳 |
