We are looking for a PhD student to join the project "A robust tool for rail fault and roughness estimation." In this role, you will develop advanced methods to estimate rail roughness and defects based on onboard vibration and sound signals-contributing to a quieter, more reliable, and cost-efficient railway system.
Project overview
To limit noise and vibrations from railway traffic, infrastructure managers need effective tools to monitor the acoustic quality of tracks. A key parameter is rail roughness, which-together with wheel roughness-generates rolling noise during train passages.
In this PhD project, you will develop methods for indirect monitoring of both rail roughness and localized track defects. Your work will build on and extend an advanced in-house time-domain simulation tool for wheel-rail interaction and noise. The project is carried out in close collaboration with DB InfraGO, the German railway infrastructure manager, which will provide measurement data and test cases.
Research environment
This project is part of the activities within the Swedish National Centre of Excellence in Railway Mechanics CHARMEC - Chalmers Railway Mechanics. CHARMEC's long-term goal is to reduce the railway's cost of production, environmental impact, and operational maintenance, while improving safety, reliability, and quality of transport.
The position will be placed at the Division of Applied Acoustics, Department of Architectural and Civil Engineering. As a PhD student, you will belong to the Graduate School of Applied Acoustics.
Your profile
Required qualifications:
• A Masters degree equivalent to at least 240 higher education credits in Mechanical Engineering, Engineering Physics, Civil Engineering, or in a similar field, with a strong specialization in Sound and Vibration (We also welcome applications from candidates who will graduate soon).
• Solid knowledge of structural mechanics and numerical methods
• Proficiency in programming
• Excellent communication skills in English, both written and oral
• Ability to work independently, take initiative, and assume responsibility
• Strong collaborative skills, due to the interdisciplinary and industry-focused nature of the project
• Analytical problem-solving skills and a genuine interest in research
• Ability to disseminate results and engage with academic, industrial, and societal networks
Merits:
• Experience with Matlab
• Prior coursework or project experience in railway mechanics
• Background in signal processing
• Knowledge of machine learning techniques
Main responsibilities
Your primary responsibility is to pursue your doctoral studies, which includes:
• Developing scientific concepts and presenting your results in writing and orally
• Taking relevant advanced-level courses according to the Graduate School's curriculum
• Participating in undergraduate teaching or other departmental duties, up to 20% of full-time.
