30 credits - Life length and reliability testing of EEE components i Sodertalje

Scania is a world-leading provider of transport solutions. Together with our partners and customers we are driving the shift towards a sustainable transport system. In 2017, we delivered 82 500 trucks, 8 300 buses as well as 8 500 industrial and marine engines to our customers. Net sales totalled nearly SEK 120 billion, of which about 20 percent were services-related. Founded in 1891, Scania now operates in more than 100 countries and employs some 49 000 people. Research and development are concentrated in Sweden, with branches in Brazil and India. Production takes place in Europe, Latin America and Asia, with regional production centres in Africa, Asia and Eurasia. Scania is part of Traton Group. For more information visit www.scania.com.

Om tjänsten

Scania is now undergoing a transformation from being a supplier of trucks, buses and engines to a supplier of complete and sustainable transport solutions.

Thesis project at Scania is an excellent way of making contacts for your future working life. Many of our current employees started their career with a thesis project.

Background:
The complexity of electrical systems on commercial vehicles are continuously increasing, and as a consequence the amount of EEE-components (Electronic, Electric and Electro-mechanical) increases. At the same time the demands on life length and reliability are raised to higher and higher levels.

Traditional testing of EEE-components often is done on component level with well-established and standardized test methods. The component is in operation as in the vehicle in some tests and non-operational in some tests. The life length testing are often based on Arrhenius/Coffin-Manson theories and includes as an example operation of the component at different loads and temperatures.

Some of the test involves a long test time and this can be a problem since the time to market for new development is more and more critical, there have also been some cases where the component has passed the standardized tests, but still caused field quality issues during the end customers operation of the vehicles.

Target:
Create a road map for the work to merge traditional component testing with the life length testing in order to reduce the total time for testing, but still with confidence that design weakness in the component is found.

Assignment:
Compare life length tests for EEE-components and investigate how different type of components should be tested or if the standardized tests are sufficient enough. Investigate if it’s possible to have different test depending on the type of design that the EEE-component have (Example electronic or electro mechanical) or if it’s possible to perform different test on different parts of the component (break down).

Assignments which can be included in the work are:

  • Literature study of relevant articles in this matter and suggest a “roadmap” for further work.
  • Compare different test methods regarding life length and suggest a suitable test method and/or test equipment.
  • Create engineering guidelines how the tests shall be performed and for which type of components and/or design the testing is needed,

Candidate profile:

  • Close to MSc Engineering degree in Mechanic, Material, Electronic, Electrical or Engineering physics.
  • Committed, self-starting, taking responsibility, high focus and interest to create new technique.
  • Solution and result driven approach.

Number of students: 1.
Start date: January 2019
Estimated time needed: 20 weeks
