Thesis Worker at Volvo Cars 
Welcome to explore the world of Volvo Cars (VCC) by writing your thesis with us! As a thesis worker in our organization, you are supported by a supervisor who follows you during your project. All thesis projects are arranged in business-critical areas and therefore you will be able to contribute to our company purpose – providing freedom to move in a safe, sustainable and personal way – from day one!
 

Background
You're about to embark on a challenging and impactful research journey in the field of mechanical engineering and electromobility. Our company is offering a unique master´s opportunity focused on analysis of structure borne vibration signals in endurance testing. VCC use special designed damage waring systems, designed to monitoring and learn the vibration levels on a test object. If a component change behavior is the system designed to stop the test before a serious damage occur. The system is a key in our BEV driveline testing and development. If you are a passionate master’s student with a strong technical background, have affinity for testing, data analysis and creative thinking, this is the perfect project for you.

Scope

Market competition in electromobility is growing tougher every year. This drives the manufactures to create new products faster than ever before. This has resulted in increase of performance in the drivetrain and thus higher wear and stresses on the mechanical components. Analysis and verification of these components are vital to secure a safe and reliable product for the end customer. This has been especially challenging to understand different failure modes without interrupting tests.

Objectives of the thesis:

•    Literature study: Order analysis, frequency analysis, classifications 
•    Test setup: Definition of test object, system setup
•    Test data processing ongoing test
•    Post test data processing
•    Post test data processing from external supplier system test data 
•    Create handbook for VCC internally usage, how to setup system at test start, how to perform order analysis

What you´ll bring 

We are seeking a passionate master’s student/s with a strong technical foundation, proficiency in analysis, coding and testing. Additionally, attention to detail, a research-oriented mindset, and a commitment to the project are crucial.
