VIbro-acoustics of PERiodic Media KU Leuven
Vibro-Acoustics of Rotating Electric Machines: Prediction, Validation and Solution KU Leuven
Within the context of electric mobility and the need for lower cost electric machines, emerging designs gain interests with less usage of expensive permanent magnets; for instance reluctance machines. However high tonal and unpleasant acoustic noise from structural resonances may occur. These resonances are generally excited by electromagnetic forces induced within the rotating magnetic field of the machine. Hence the accurate prediction of ...
VAMOR Vibro-Acoustic Model Order Reduction KU Leuven
VAMOR contributes to a more sustainable and quieter future for Europe. Noise pollution has arisen as one of the key factors towards the degradation of the quality of life in European societies. Adding noise treatments commonly leads to an increase in mass and/or volume usage, harming the sustainability of the respective products, e.g. leading to heavier vehicles. To avoid such solutions and striving for the sustainability and optimal acoustic ...
Modelling, analysis and validation of variability effects in vibro-acoustic metamaterials for broadband noise and vibration attenuation KU Leuven
Sound perception based intelligent modeling and realization of innovative vibro-acoustic metamaterial solutions KU Leuven
Time-varying vibro-acoustic digital twins towards a sustainable society. KU Leuven
The current European energy crisis has re-established the importance of accelerating our transition towards a more sustainable society and industry. The sustainable design and monitoring of vehicles and machines is an important contributor to this transition. To improve sustainability, a delicate balance between the conflicting criteria of health, profitability and environment needs to be found. One of the most important health considerations ...
The influence of size and boundary conditions on the sound and vibration isolation performance of vibro-acoustic metamaterials KU Leuven
This PhD track focuses on the investigation of the dynamics of finite VAMM plates, focussing on (i) the influence of edge effects of finite samples and (ii) transmission reduction by aperiodic design. Model reduction will be used for efficient and accurate finite VAMM performance predictions and energy flow quantification and visualization. Fast (e.g. Bayesian) optimization schemes will be used to optimize VAMM performance under different ...
Model Order Reduction of coupled vibro-acoustic systems KU Leuven
This PhD focuses on efficient model order reduction schemes for one-way coupled and fully coupled vibro-acoustic analysis where the acoustic domain is described using a boundary discretisation. Where efficient model order reduction of unbounded and bounded vibro-acoustic systems is well-established using finite element and (in)finite elements for the structural and acoustic part of the problem, the combination of finite elements for the ...
Vibro-acoustic design feature extraction using Artificial Intelligence KU Leuven
Noise in the interior of an automotive cabin depends on many design factors of the cars, thus making it difficult for Original Equipment Manufacturers to optimize and/or define targets for new innovative designs. Overall system-level modelling strategies are required and must incorporate component behavior details; while making sure not to reinvent the wheel. To this end, the objectives of the DC will be to develop a holistic modelling ...
