PhD Nonlinear dynamics & vibration analysis for structural/condition monitoring (V23.0484)

We are looking for a candidate to undertake research in the field of dynamics and vibration, with a particular focus on evaluating the structural integrity of mechanical, civil, and aerospace engineering structures via nonlinear dynamics analysis.
Modal analysis is a well-established technique used to accurately characterize the dynamic behaviour of vibrating engineering systems with linear behaviours, both in theoretical and experimental domains [1-2]. The resulting modal parameters, such as natural frequencies, damping ratios, and mode shapes, are used extensively in the design, analysis, and maintenance of engineering structures such as buildings, bridges, and aerospace structures [3-4]. Unfortunately, most of the industrial structures exhibit nonlinearities in certain local regions or possibly in the whole of the structure, which limit the validity of the modal analysis assumption of linear behaviour, making it challenging to apply modal analysis to deal with nonlinearities.
The main objective of this position is to develop an innovative Nonlinear Modal Analysis methodology that integrates vibration analysis, data-driven modeling (e.g. MIMO NARX modelling, Neural Networks), and nonlinear frequency domain analysis (e.g. Nonlinear Frequency Response Functions). This integrated approach aims to reveal the underlying linear and nonlinear dynamic characteristics of structures. The successful implementation of this research will have wide-ranging implications across engineering fields, including applications such as structural and condition monitoring, predictive maintenance, and structural design and modification.
An outstanding opportunity is available for a Ph.D. candidate to join our groundbreaking research in this advanced field. This position provides a unique chance to make significant contributions to the forefront of scientific exploration, while actively shaping the future of dynamic systems theory.

• desirable practical expertise in utilizing data acquisition instruments and transducers such as NI modules, Siemens Scadas, modal shaker, accelerometers, etc.
• proficient programming skills in Matlab/Python/LabVIEW, with an added advantage of specific experience in popular deep learning frameworks like PyTorch and TensorFlow
• demonstrated capability in independent research, exemplified by exceptional performance in the MSc thesis
• excellent proficiency in both spoken and written English, and knowledge of spoken Dutch would be advantageous for this purpose
• possession of a critical mindset and the ability to think analytically.

We offer in accordance with the Collective Labour Agreement for Dutch Universities:

• a salary of € 2,770 gross per month in the first year, up to a maximum of € 3,539 gross per month in the fourth and final year (based on a full-time employment)
• a holiday allowance and end-of-year bonus of respectively 8% and 8.3% of your gross annual income
• a full-time position (1.0 FTE) for four years: first, you will get a temporary position of one year with the option of renewal for another three years; prolongation of the contract is contingent on sufficient progress in the first year to indicate that successful completion of the PhD thesis within the contract period is to be expected. A PhD training program is part of the agreement and you will be enrolled in the Graduate School of the Faculty of Science and Engineering.
