Master Thesis - Acoustically transparent wind tunnels for vehicle testing
"Founded in 1927, the Volvo Group is committed to driving prosperity and shaping the future landscape through sustainable transport, mobility, and infrastructure solutions.
Transport is at the core of modern society. Imagine using your expertise to shape sustainable transport and infrastructure solutions for the future? If you seek to make a difference on a global scale, working with next-gen technologies and the sharpest collaborative teams, then we could be a perfect match.
About the thesis work
Acoustically transparent wind tunnels enable cost-effective studies of flow-generated sound, such as wind noise around the cab of a truck. The walls of the wind tunnel control the flow but are designed to be acoustically "transparent". Placed in an already existing acoustic room, accurate acoustic measurements can then be carried out outside the tunnel in a simple way. The project aims to achieve a solution that is easy to construct, with available materials, that produces results with engineering precision. The proposed method has the potential to reduce both costs and lead time in the development manifold.
The M.Sc. Thesis work will be performed at Volvo Group Trucks Technology (Gothenburg) or at KTH (Stockholm). (30 ECTS credits/student)
Scope of the project:
• Literature survey – state of the art and possible engineering solutions
• Simple modelling
• First experiments with material candidates
• Report
Your profile:
We are currently seeking one or two Master's students in the fields of mechanical engineering, applied physics, or electrical engineering. You should have taken courses in acoustics and preferably aeroacoustics. In addition to the academic background, you should have knowledge in MATLAB or Python, as well as a good understanding of signal processing. Furthermore, we hope that you have hands-on experience and knowledge in measurement techniques which will be highly valued.
Ready for the next move?
If you want to make a real impact in your career, the transportation business is where you want to be. We look forward to meeting you.
