On the balancing of structural and acoustic performance of a sandwich panel based on topology, property, and size optimization

Autor: Per Wennhage, Eleonora Lind Nordgren, Christopher John Cameron, Peter Göransson

Publikováno v: Journal of Sound and Vibration. 333:2677-2698

Balancing structural and acoustic performance of a multi-layered sandwich panel is a formidable undertaking. Frequently the gains achieved in terms of reduced weight, still meeting the structural design requirements, are lost by the changes necessary

Optimising open porous foam for acoustical and vibrational performance

Autor: Eleonora Lind-Nordgren, Peter Göransson

Publikováno v: Journal of Sound and Vibration. 329:753-767

A computational method for designing optimal arrangements of multilayer noise and vibration treatments in general and porous open cell foam in particular is discussed. The method uses finite element solutions to Biot's equations for poroelastic mater

Vibroacoustic response sensitivity due to relative alignment of two anisotropic poro-elastic layers

Autor: Eleonora Lind Nordgren, Jean-François Deü, Olivier Dazel, Peter Göransson

Publikováno v: Journal of the Acoustical Society of America
Journal of the Acoustical Society of America, Acoustical Society of America, 2013, 133 (5), pp.EL426-EL430. ⟨10.1121/1.4802184⟩

The effects of relative alignment of two different types of anisotropic open cell porous materials are investigated in terms of the acoustic response of a multi-layered configuration. Numerical experiments, where gradient based optimization technique

Parametric relations for porous foams and their use in optimization of structural acoustic performance of multilayer trim components

Autor: Peter Göransson, Eleonora Lind

Publikováno v: The Journal of the Acoustical Society of America. 120:3345-3345

Lightweight porous acoustic multilayer trim components have traditionally been specified in terms of sound absorption and sound transmission loss performance targets. Importantly, the material specification of the trim component developed only for ab
