Determination of local stiffness variations in crankshaft

Background
High demands on shortened lead times and reduced cost in the automotive industry drive the production development increasingly towards virtual development. Traditional methods of problem solving based on costly and time-consuming physical test loops are increasingly replaced with virtual prototyping using numerical methods such as the FEM.

Ability to handle increasingly complex relationships present during machining of crankshafts demands deeper understanding of a number of different phenomena that arises.To be able to obtain an accurate FEM-simulations connected to challenges during the turning process of crankshaft the knowledge about the possible varying stiffness is crucial. 

Scope

• Use FEM models and experiments to obtain local stiffness variations in crankshaft.
• Compare virtual crankshaft models with constant and varying stiffness in different load cases.
• Compare results from FEM calculations with ”real life” measurements in machine equipment. How well the calculations conforms to the measurements?
• Make conclusions about applicability of FEM-analysis in this type of problems.

Profile
In order to be successful in this thesis you need to have:
- Good knowledge of FE theory and modelling.
- Excellent analytical skills.
- Ability to work independently and to read and understand scientific papers.
- Practical experience is meritorious.
- Ability to work together with other ongoing thesis project.
