Physically Consistent Vibroacoustic Substructuring involving Continuous Interfaces: Applied to Concept Phase Car Body Optimisation KU Leuven
Over the past decades, in order to keep up with both the legislations governing noise emissions and the growing customer expectations, the continuous search for improved noise and vibration performances has been playing a key-role in the development process of new vehicles. However, to meet these expectations in today’s competitive environment, it is not enough simply to bring a better product into the market. You have to bring it sooner and ...
Analysis and design of lightweight solutions for structural vibrations induced by subsonic confined flows KU Leuven
To reduce the fuel consumption and the material use, the use of lightweight materials is entering the industrial practice for flow-confining structures, such as ventilation ducts, automotive exhaust systems and car underbodies. Unfortunately, such lightweight constructions typically exhibit poor vibro-acoustic properties and unsteady pressure fluctuations in the flow can easily excite vibrations of the structure. These flow-induced vibrations ...
Design and analysis of compact, lightweight material concepts for sound mitigation in flow ducts. KU Leuven
In applications such as automotive exhaust and HVAC systems, a flow duct is the main transmission path for the noise generated upstream. The increasing legal regulations and customer expectations regarding noise emission call for efficient noise control measures in such systems. However, the conventional solutions require a large volume (and subsequent weight) to be effective at low frequencies, conflicting with the trend towards lightweight ...

Developing Multifunctionally Optimal composite Structures for construction and transportation applications with an emphasis on environmental sustainability KU Leuven
Due to unmitigated global warming, the EU has suffered unprecedented heatwaves in 2022 resulting in over 12,000 deaths and Europe's worst drought in 500 years. This is attributed to the heavily fuel-dependent construction and transportation sectors - collectively responsible for around 60% of EU's greenhouse gas emissions in 2020. The chief reason lies in these industries' over-reliance on legacy/outdated component architectures, with limited ...
Seeing Sound and Vibrations. Ghent University
Certain light-emitting materials (or phosphors) are able to internally store energy for a long time.
Upon mechanical stimulation, such as pressure or scratching, some can emit this energy in the
form of visible light. These mechanoluminescent (ML) phosphors only start to show their full
application potential.
The first goal is to use these phosphors for the visualization of ultrasonic fields. Ultrasound,
defined ...
Comprehensive study of flow instabilities and sound wave generation in the wake of perforated plates. KU Leuven
eVTOLUTION : EVTOL MULTI-FIDELITY HYBRID DESIGN AND OPTIMIZATION FOR LOW NOISE AND HIGH AERODYNAMIC PERFORMANCE Vrije Universiteit Brussel
tools that will enable novel aircraft architectures with improved aerodynamics and reduced noise emissions. This project addresses more
specifically the design issues of electric Vertical Take-Off and Landing aircraft developed for Urban Air Mobility, but the innovative
design/optimization ...
A new generation of high-performance building materials and elements integrating aerogels and textile reinforced cement composites KU Leuven
Nowadays’ regulations are pushing the construction industry to meet the ambitious global goals of a sustainable society such as energy-saving, reduced CO2-emission and use of resources, and efficient construction. High-performance construction materials and systems combining mechanical and thermal properties can answer this call. At a mechanical level, Textile Reinforced Cements (TRCs) have shown their high competitiveness compared to ...
