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 ...
Combined shape and topology optimisation of shell structures using FE-based parameterisations KU Leuven
Virtual measurements for exterior vibro-acoustic problems using experimental modal models KU Leuven
This paper presents a virtual sensor scheme for vibroacoustic radiation applications based on experimental modal state-space models and sparse measurements. A Kalman filter is used for the estimation combining data from the acoustical and the structural domain together with the numerical modal process model. It is proposed to use Gramians, as an energy-related measure of a system’s observability which enables assessing the observability of the ...
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. ...
Framework for metamodel-based design optimization considering product performance and assembly process complexity KU Leuven
This paper proposes a method for simultaneous evaluation of the assembly process complexity together with the performance of the future product. It allows for product design optimization, considering different aspects of the future design at the early stage of the development process. The proposed method, embodied in a fully automated framework, substitutes the traditional sequential development process with a more efficient and rapid combined ...
