Luleå University of Technology is in strong growth with world-leading competence in several research areas. We shape the future through innovative education and ground-breaking research results, and based on the Arctic region, we create global social benefit. Our scientific and artistic research and education are conducted in close collaboration with international, national and regional companies, public actors and leading universities. Luleå University of Technology has a total turnover of SEK 1.9 billion per year. We currently have 1,840 employees and 17,670 students.

In the coming years, multi-billion investments will be made in large projects in Northern Sweden to create a fossil-free society both nationally and globally. Luleå University of Technology is involved in several of these cutting-edge research projects and in the societal transformation that they entail. We offer a broad range of courses and study programmes to match the skills in demand. We hope that you will help us to build the sustainable companies and societies of the future.

Operation and Maintenance is a rapidly growing research area as it is recognized as an important enabler for the business performance by industry all over the world. For many industries maintenance costs are one of the biggest individual cost items. Effective maintenance can generate income for industry through better facility utilization and higher availability. Through well planned maintenance, external and internal operational risks can also be controlled and minimized. The division of Operation and Maintenance Engineering is multidisciplinary in nature and includes many disciplines of science and emerging technologies. The activities of the Division are aligned towards finding synergies with other engineering disciplines and building networks with many active research groups, locally and worldwide.

Subject description Operation and Maintenance Engineering deals with the development of methodologies, models and tools to ensure high system dependability and efficient and effective maintenance processes for both new and existing systems. One area of the research at our division focuses on condition monitoring and predictive technologies, where measurement and modelling of different asset behavior plays a significant role.

Project description This PhD project will deal with a part of a digital twin system where machine learning approaches and Multiphysics simulation in computational modelling will be combined. The research project will be conducted within the Railway system domain. The research questions that will be addressed in this project is related to the simulation of the magnetic field propagation on the rail surface and the possibility of identifying key parameters governing various defects on the rail from the response field. The project will be connected to ongoing European Union research projects. Real case studies of railway track sections will be used to validate and support the developed approaches for railway defect detection. The purpose of the research is to generate knowledge which can be used to improve maintenance limits of track infrastructure.

Duties The duties within the PhD project includes active participation in the research and development of deliverables connected to EU-projects. Except for the theoretical thesis work, practical work related to computer programming, simulation and on-site field measurements of different aspects like eddy current and electromagnetic induction will be included. Other duties related to the PhD education will be specified within the individual PhD study plan.
