MSc Thesis proposal at Volvo Group
(60 ECTS credits, 40 weeks, One student)
Structure-borne noise assessment of automotive components using the blocked force approach
The commercial vehicle industry is shifting from ICE (Internal Combustion Engine) to EDU (Electric Driving Units) as a propulsion mean, resulting in lower noise emission in society and a quieter environment for the driver. Without the masking effect from the ICE, requirements on using silent components like pumps, compressors and fans are getting tougher especially when it comes to structure-borne noise. Therefore, an appropriate structure-borne noise characterization method is required both for target settings towards suppliers and as input data for simulations.
In this master’s thesis, we aim at reviewing some fundamental concepts of the blocked force approach. The thesis includes both simulation and measurements.
Your profile:
· One Master’s student in mechanical, applied physics or electrical engineering, or from the “sound and vibration” program
· Knowledge in Finite Element Methods and MATLAB or Python
· Good knowledge in linear algebra, signal processing
· Good hands-on capability and knowledge in measurement technique
The Master of Science Thesis work will be performed at Volvo Group Trucks Technology, (Gothenburg, Sweden) and starts 1 September 2025.
Industry supervisors: Sophie Girolami, Torbjörn Ågren, Frédéric Wullens at Volvo GTT
University supervisors: TBD
