"Cutting-edge research requires excellent minds – particularly more females – at all levels. Launch your mission with us and send in your application now!" Prof. Pascale Ehrenfreund - Chair of the DLR Executive Board

In cruise flight, passengers may be exposed to considerable noise. But how does the noise get from the source to the passenger? In two ways. Airborne sound radiates from a source of noise, such as the jet engines, and is perceived by passengers in the cabin. In addition, engine vibrations spread through the aircraft structure reaching the cabin. Similar to loudspeakers, the vibrating surfaces of the cabin in turn emit airborne sound, which is perceived by passengers as noise.
In the Department of Structural Dynamics and System Identification of the Institute of Aeroelasticity, DLR addresses the issue of structure-borne cabin noise.

Your tasks:

  • familiarization with existing experimental and simulation analysis methods for structural vibrations and structure-borne noise in the acoustic frequency range
  • structural dynamic modeling of aircraft fuselages and cabins with Finite Element methods in the higher frequency range
  • comparison of numerical models with measured data
  • development of methods for automatic model updating
  • development of new methods for the analysis and comparison of structure-borne noise and transfer paths from simulation and measurement data
  • preparation of project reports and scientific publications
  • presentation of results to clients as well as in conferences

Your qualifications:

  • completed university studies in engineering sciences (Mechanical, acoustics or similar) or physics with knowledge in the field of mechanics or acoustics (M.Sc./M.Eng./Diplom)
  • good knowledge of Finite Element Methods (FEM) in the area of dynamic analysis preferably with MSC NASTRAN or ANSYS
  • good knowledge in the field of structural dynamics
  • strong coding experience in Matlab
  • experience in coupled analysis (fluid-structure) in COMSOL Multiphysics
  • experience in vibration measurements and signal processing
  • highly proficient in written and spoken English

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (m/f/non-binary). Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
