Modelling and assessment of structural damage to masonry structures due to vibrations of moderate amplitude Hasselt University
Computational analysis of flow-induced vibrations in fuel rod bundles of next generation nuclear reactors Ghent University
Currently, lead fast reactors are being designed to reduce the radioactive waste and its lifetime. In this PhD, the vibrations of the fuel rods in the liquid metal will be analyzed using three-dimensional calculations on high-performance computers. The flow-induced vibrations will be calculated by coupling state-of-the-art programmes, namely one for the liquid metal flow and one for the vibrating rods.
Magnetic forces and magnetostriction in ferromagnetic cores: modelling and optimization with respect to vibrations and noise Ghent University
Electromagnetic devices, such as rotation electrical machines and transformers, produce vibrations and noise. Major sources are magnetic forces and magnetostriction in the ferromagnetic cores. The main goal in this project is to diminish those vibrations and noise. Several steps are required, such as the accurate measurement and modelling of magnetostriction and the study and implementation of multi-objective optimization procedures.

Data-driven modelling and control of nonlinear vibrations: Making the best of the system identification and machine learning worlds KU Leuven
Modern computers allow for increasingly easy and efficient processing of large amounts of data. For these reasons, system identification and especially machine learning techniques are becoming increasingly popular in the field of mechanics. Therefore, in line with the current developments, this research will be strongly data-driven. Moreover, it is specificially focused on nonlinear systems, since industrial systems are becoming increasingly ...
Dynamic vibration absorbers with arbitrary connection characteristics for reconfigurable mechanical assemblies Ghent University
Excessive vibrations are detrimental to a mechanical system’s structural integrity, performance and production quality/output. Emerging design trends incorporate light and slender material, reconfigurable and modular assemblies, and have changing loads and propulsion. This leads to vibration susceptible designs with uncertain, time-varying vibratory behavior. To reduce excessive vibrations, a passive device called a dynamic vibration absorber ...
Sabbatical Geert Degrande: Quantifying uncertainty for railway induced vibration KU Leuven
I submitted a Research Proposal entitled “Quantifying uncertainty for railway induced vibration” to the Honorary and Visiting Fellowships Committee of Peterhouse in Cambridge and was elected as Visiting Fellow at Peterhouse for the Michaelmas Term 2021. Due to restrictions imposed by the covid-19 pandemic, this stay is postponed to the Michaelmas Term 2022. During my stay at Peterhouse and the Department of Engineering of the University of ...
Rotational vibration absorber with optimized nonlinear restoring characteristic Ghent University
The objective is to develop a prototype of a rotational vibration absorber with a nonlinear restoring characteristic to reduce multi-frequency torsional vibrations in rotating machinery. The nonlinear restoring characteristic is the promising novel part that enables the absorber to mitigate multi-frequency vibrations.
The feasibility of a design chain from mathematical concept to prototype for a rotational vibration absorber will be ...
