Introduction
Thesis work is an excellent way to get closer to Scania and build relationships for the future. Many of today's employees began their Scania career with their degree project. The thesis work subject reflects Scanias need for development in different areas and the results from the thesis work is always highly appreciated. 

 

Background 
In general, the test methods for evaluating and verifying our products are always in need of improvements. One environmental aspect that is of great concern for trucks and buses are the vibrations induced by road loads and the drivetrain. To be able to do realistic and efficient vibration testing of our components we need relevant vibration loads in our test rigs that represents the actual loads in the field.  

 

Objective 
The purpose of this thesis work is to improve Scanias method for creating relevant test profiles based on truck and bus measurements. 

 

Job description 
To investigate how a test profile is created in the best way based on a measured acceleration time signal from the test track. And the intention is to primarily base this on the Fatigue Damage Spectrum method.

Perform a literature study of previous work in this area. Study the Fatigue Damage Spectrum method. Using existing data to evaluate the FDS method and comparing with current methods. Perform vibration testing in a shaker rig if needed to evaluate the FDS method. Example of topics that are of interest in the evaluation: Is the method applicable for all components? Fatigue damage for different materials Test time vs. lifetime Frequency range Statistical considerations  Road induced/drivetrain induced vibrations
