Are you eager to pursue your PhD studies alongside a dynamic and innovative team at the forefront of Method Engineering & Equipment Design in the Offshore Wind industry? If so, we invite you to join us!
Friction is present in applications to everyday life and can simply be defined as the resistance to motion of one object in contact against another one. As simple as this concept may sound, friction keeps being one of the most complex problems in physics and engineering. One of the current grand challenges concerning friction in modern engineering consists in improving the understanding and prediction of the so-called pre-sliding regime, which is characterized by built-up of the friction force, by micro surface displacements and the transition point to the sliding regime.
Within this PhD project you will explore such pre-sliding friction regime with reference to offshore wind applications concerning seafastening techniques and structural constraints in mission equipment on offshore wind installation vessels. Future mission equipment in the offshore wind industry will rely more on friction-based connections since both the mission equipment as well as transported objects are exceeding vessel sizes. These connections merely rely on contact mechanisms between the transported structure and the support elements such as friction pads or rollers. Currently, there is a lack of high-fidelity guidelines for the design, characterization and selection of these friction-based support elements. To fill this gap, you will develop testing and predictive models to quantify the friction force variation during its pre-sliding regime and quantify the variability of friction with reference to the interface features, such as interfacial stiffness, roughness, hardness and other material, environmental, and operational properties. Potential friction models will be sought within the direction of physics-informed probabilistic models, by integrating aspects of contact mechanics, tribology and acquired experimental data.
As a PhD student, you will work at the company TWD and you will also be a member of the Mechanics and Physics of Structures group (MPS), a section of the Department of Engineering Structures at the Faculty of Civil Engineering and Geosciences at TU Delft. TWD and MPS are both young and enthusiastic groups, and whose members are nationally and internationally recognized, respectively, in their fields of application. The scientific aim of MPS is to develop new physical insights and know-how in the field of mechanics and physics of structures, while the aim of TWD is to increase awareness and develop predictive capabilities on the reliability and functionality of their mission equipment.
This doctoral project is part of a larger, multidisciplinary, and international project APRIORI: “Active Product-to-Process Learning For Improving Critical Components Performance” (no. 101073551) funded under the Marie-Sklodowska-Curie Actions Doctoral Networks within the Horizon Europe Programme of the European Commission.
