This functionality comes at a cost however as the rail discontinuities in switches and crossings induce greater loading and faster deterioration compared to plain line track. S&C are therefore often characterized as "hungry assets" and it is of great interest for infrastructure managers to improve maintenance decisions for S&C. With the increased availability of sensors that allow for gathering of continuous remote condition monitoring data of S&C and other track components, there is a potential for more accurate maintenance decisions to be made with the right software tools compared to what is possible if only intermittent track inspections are used.
Project description
The goal of this project is to develop a numerical method that can determine the maintenance efforts that minimize the Life Cycle Cost (LCC) of an individual S&C. The project is multidisciplinary and will use theory and methods from structural and multibody dynamics, signal processing, machine learning and optimization to perform three main tasks in a Digital Twin; 1) System identification to determine the condition of the S&C using simulation models and data from remote sensors and monitoring cars, 2) predict future deterioration and 3) to find the maintenance actions that minimize LCC costs based on these predictions. The LCC analysis will be supported by VTI (Swedish National Road and Transport Research Institute).
The project will be carried out at Chalmers within the competence centre CHARMEC (Chalmers' Railway Mechanics Centre). The project will build on previous PhD projects on S&C dynamics and condition monitoring. The project is carried out in close collaboration with industry partners Trafikverket (The Swedish Transport Administration) and infrastructure company NRC Group.
The overall goals of CHARMEC are to achieve increased quality in railway transportation while reducing production, maintenance, operational and environmental costs via improved understanding of the mechanical behavior of railway systems. CHARMEC was formally established in 1995 and has produced 54 PhDs since. CHARMEC is primarily active in national and EU-level research projects but has a global outreach and recognition in scientific publications and conferences.
Major responsibilities
Your major responsibilities as PhD student is to pursue your own doctoral studies. This includes developing scientific concepts and communicating research results verbally and in writing. In addition to research project activities, you will also take courses on the advanced level adequate for the project following the syllabus of the Graduate School Solid and Structural Mechanics. The position is a full-time temporary employment limited to 4.5-5 years including teaching or other departmental duties corresponding to 10-20% of working hours. You will be employed by Chalmers and will receive a salary according to current salary agreements.
