Experimental validation of a topology optimized 2D sandwich panel for sound transmission minimization KU Leuven
In industry, an increasing pressure is perceived to obtain dynamical systems which are light-weight, load-carrying and achieve excellent noise and vibration properties. sandwich panels with specifically designed structural-acoustic cores have shown potential to reconcile these conflicting requirements. Optimization techniques can be used to automate the design process while making a trade-off between the conflicting requirements. This work ...
Vibroacoustic topology optimization for sound transmission minimization through sandwich structures KU Leuven
Recently, metamaterials, sandwich panels, and a combination of both have shown potential for creating lightweight, load-bearing structures with good noise and vibration suppression properties. However, designing these structures is difficult due to the complex vibroacoustic innate physics and the need to balance conflicting requirements. Structural optimization methods can help address this multi-functional, multi-physical design challenge. ...
Modeling of complex moving sound sources using a cut finite element method approach KU Leuven
While acoustic analysis with the finite element method is commonly done under the assumption that the source location is stationary, this is not always a valid assumption. This article derives a method to simulate moving sound sources using an unfitted mesh approach, where the source boundary is described by cutting through elements, known as the cut finite element method (cutFEM). By using such an approach the mesh stays static during ...
