Thesis im Bereich Bionik – Akustische Simulation der Lautproduktion von Maulwurfsgrillen

Advanced Research Project (ARP), Masterthesis, Bachelorthesis, Advanced Design Project (ADP)

This interdisciplinary project, conducted in cooperation with an international partner from the field of neurobiology, aims to acoustically simulate the sound production of mole crickets . Crickets produce relatively loud sounds by stridulating ( rubbing ) their forewings together , relative to their body size and presumed energy expenditure , suggesting high acoustic efficiency. Furthermore, even small changes in the morphology of the wings ( e.g. , due to sexual dimorphism ) lead to a characteristic change in the emitted sound.

The goal of this thesis is to create an acoustic simulation of the sound generation of crickets' chirping . The simulation is intended to reproduce the phenomena described above in order to better understand them and, for example, to develop new bio-inspired design methods and actuator principles .

Your tasks:

  • If necessary, guided training / refresher of the basics of structural dynamics , finite elements, if necessary acoustics
  • Development of an acoustic (FE) simulation of the sound production of mole crickets : The basis for this is a CT scan of the forewings , which is segmented and discretized with finite elements .
  • Comparison of simulation results with recordings of mole cricket sounds

This is what you bring with you :

  • Independence, motivation, initiative
  • Good to very good grades
  • Creativity and interest in a new, challenging topic
  • Advantageous: Previous knowledge in structural dynamics or finite element method (previous knowledge of acoustics not necessary)

This is what we offer you :

  • An exciting and relevant topic in the field of structural dynamics with high relevance in industry and science
  • Die Möglichkeit, bei Interesse und Erfolg der Arbeit deine Arbeitsergebnisse zu publizieren und deine Konferenzteilnahme finanziell zu unterstützen
  • Support from a competent and motivated team
  • A workplace in our modern student room
  • Je nach Interesse, Eignung und Möglichkeit können wir dir einen Entwicklungspfad im Fachgebiet oder Fraunhofer LBF anbieten
