Master Thesis - Blocked Force Method to Acoustic Sources
Scania GroupRekommenderat
Sammanfattning
This thesis opportunity focuses on characterizing structure-borne noise sources in Scania vehicles using the Blocked Force Method. The selected student will analyze components like wiper systems or compressors to assess their contribution to interior noise. The role involves developing a repeatable workflow for measurements and preparing a final presentation and technical report. The position is based in Södertälje, Sweden, and is expected to last 20-25 weeks, starting in January or February 202Jobbet i korthet

Beskrivning
Background:
The Blocked Force Method is a component-based approach used to characterise structure-borne noise sources independently of the receiving structure. The blocked forces represent the forces that a source would exert at its interfaces if the receiving structure were rigidly constrained. Once the blocked forces and the relevant transfer functions are known, the contribution of the source to the vibration or acoustic response of a complete vehicle can be estimated without repeatedly testing the source in its final installation.
Goal:
The goal of this thesis is to characterise a selected component, such as a wiper system or compressor, and determine its structure-borne contribution to interior noise. The thesis also aims to develop a repeatable workflow for characterising components mounted on Scania vehicles. This workflow will support the identification of dominant excitation forces, transfer paths, and frequency ranges that influence the interior noise response. The results may also support component benchmarking, installation optimisation, and the development of effective noise-reduction measures during the early stages of vehicle development
Assignment:
The assignment is divided into four parts:
