Contribute to the revolution of railway embankment monitoring.
Job description
Railway embankments form the foundation of the railway system and play a critical role in ensuring the safety, reliability, and resilience of rail transport. As these assets age and are exposed to increasing traffic loads and environmental effects, efficient methods for monitoring their condition become essential. Traditional inspection approaches can be costly, time-consuming, and limited in spatial and temporal coverage. This PhD project addresses these challenges by developing innovative methods to assess railway embankment health through the integration of multiple monitoring technologies, enabling more frequent, scalable, and data-driven asset management.
The project will investigate the integration of Axle Box Acceleration (ABA), Laser Doppler Vibrometry (LDV), and Track Geometry (TG) data to enable indirect and frequent assessments of railway embankment conditions. Using measurement data collected by the CTO monitoring train in the Netherlands, the research will examine the relationships between LDV measurements and existing indicators of track quality derived from ABA and TG data, aiming to establish robust indicators of embankment condition.
To support the interpretation of monitoring data, a physics-based train–track–embankment interaction model will be developed using finite element (FE) and/or multibody dynamics (MBD) approaches. The model will be used to investigate the mechanisms governing vibration responses measured by LDV and to improve the understanding of how embankment condition influences train-induced dynamic behaviour.
Transfer functions linking LDV, ABA, TG, and wayside sensor measurements to embankment responses will be derived and validated using field data. These relationships will provide a framework for translating routinely collected monitoring data into actionable information about embankment health and performance.
As part of the project, you will collaborate closely with railway industry partners, participate in discussions, and receive feedback on the development and implementation of your research. Limited teaching responsibilities are also included in the position.
As a PhD candidate, you will join the Railway Engineering Section within the Department of Engineering Structures at the Faculty of Civil Engineering and Geosciences of TU Delft. You will work closely with ProRail, the Dutch railway infrastructure manager, supporting the testing, validation, and practical implementation of your research outcomes. The supervisory team consists of Prof. Zili Li and Prof. Rolf Dollevoet.
The Department of Engineering Structures focuses on the development of resilient, smart and sustainable structures and infrastructures. Our aim is to meet societal demands in transportation, the energy transition and sustainable reuse. Research themes include dynamics of structures, mechanics of materials related to e.g. climate change, modelling and design of railway systems, multi-scale modelling of pavement materials and structures, reuse of materials, structures and parts of structures, assessment methods for structures, smart monitoring techniques, design methods, replacement and renovation of civil infrastructure and development of new materials and maintenance techniques. Our unique Macro Mechanics Laboratory facilities support full-scale testing, monitoring and modelling of structures to facilitate implementation of innovations. The department delivers both groundbreaking research and world-class education for undergraduate and graduate students. As a team, we represent different backgrounds, skills and views. We foster an inclusive culture, as our combined identities, attitudes and ambitions widen our perspective and make up our strengths.
Job requirements
We are looking for an excellent candidate with the following qualifications, knowledge and skills:
- A master's degree in Civil, Geotechnical, Mechanical, Aerospace Engineering, Applied Mathematics/Mechanics, Computer Science or related areas.
- Demonstrated competences in one or more of these categories: railway/structural engineering, structural dynamics, vibration measurement and analysis, structural health monitoring, data science or related fields.
- Programming skills in one or more scientific computing environments, such as Python, MATLAB, or similar.
- Experience with numerical modelling and simulation, preferably using finite element (FE) and/or multibody dynamics (MBD) approaches.
- Ability to collaborate effectively with academic researchers and industry partners.
- Excellent command of English, both verbal and in writing.
If your native language is not English and you do not hold a degree from an institution in which English is the language of instruction, you must submit proof of English proficiency from either TOEFL (minimum total score of 100) or IELTS (minimum total score of 7.0).
