Vibration analysis of crankshaft milling

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.

During the turning process of the crankshaft, there is problem to contain the narrow tolerances due to bending and vibrations caused by the number of revolutions / min.

Scope

• Use FEM models and simulations in order to evaluate and increase the understanding of the bending and vibrations phenomenon caused by number of revolutions / min.

• 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.

• 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.
