This is the world of Wölfel. You have a great enthusiasm for renewable energies? Then we would be delighted if you support us with your Bachelor/Master Thesis in the area of CAE analysis of gearbox vibrations/sound radiation of wind turbines in Höchberg (near Würzburg).

As an innovative and crisis-proof family business, we have been offering engineering services and system solutions in the fields of structural dynamics, vibration technology and acoustics for more than 50 years. We are looking for talents who want to make a difference and push things forward.

• With your ideas to success: Central part of your Bachelor/Master Thesis is the calculation of the sound radiation of wind turbines due to gear vibration excitations. You will support us in the development of CAE solutions using the finite element program Abaqus and the multi-body simulation software SIMPACK.
• You are shaping our future: The goal of your Bachelor/Master Thesis is to transfer the result of a gearbox vibration analysis in SIMPACK to a finite element model in order to calculate the surface velocity and the sound radiation. The main focus is on the use of infinite elements to calculate the radiation with free-field boundary conditions as well as the transfer of the surface rapidity via the so-called recovery matrix as a sound excitation source. Furthermore, the development of an efficient post processing using commercial programs like Altair Hyperview, ABAQUS CAE/Viewer, Matlab or Python is an important part of your work.
• Responsibility and practical experience: You analyze which areas of the wind turbine (tower, nacelle or blade) dominate the sound radiation in certain frequency ranges. With this result of your Bachelor/Master Thesis, targeted countermeasures can be defined and virtually examined afterwards.
