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 are done with physical tests, vibration, temperature as an example on component level with well-established and standardized test methods. Some of the test involves a long test time and this can be a problem regarding development time.

For mechanical parts on the other hand, the simulations are more widely used and often done early in the development process. The results gives input if physical testing is needed and/or if any dedicated test needs to be done in order to verify the calculation/simulation results.

Scania has done a few calculations/simulations on EEE-components from a vibration/temperature damage point of view with good results. The challenge is that the EEE-components usually are designed of a lot of different materials and often with a complex structure, therefore it can be needed to verify the calculations with dedicated tests, such as natural frequency measurements and damping factors at different temperatures.

Create a road map for the work to merge traditional EEE-component testing with the simulation results and how to determine if and which physical testing that is needed to correlate the simulation with the actual design. As mentioned above is the components usually complex and therefore a study about suitable measurement methods must be included in the work, it can be measurement with accelerometers, laser or other measurement methods.

Based on the already made FEM simulations on EEE- components:

  • Literature study of relevant articles in this matter and suggest a "roadmap" for further work.
  • Compare different measurement methods regarding structural behavior of small/complex components.
  • Create engineering guidelines how the work flow should be between calculation/simulation and testing departments.
  • Evaluate simulations on EEE-components or critical parts of the components.

Candidate profile:


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