URANUS Project (Funded by the European Commission)

Partners: Imperial College of London (UK), Robert Bosch GmbH (Germany), Dutch Light Railway (Belgium), LMS (Belgium)

The project was aimed at improving product design methods by developing validated mathematical models and dynamic forces. The validated model would then be able to provide reliable predictions for vibration and noise. The main tasks of the project were:

  • The development of techniques for finite element model improvement using modal test results.
  • The development of an iterative technique for updating the dynamic forces, based upon the use of sensitivities.
  • The computation of the structural sensitivity values based upon the use of the improved mathematical model.
  • The computation of the acoustical sensitivity values based upon the use of the structural sensitivity values and of the measured or computed exterior noise reduction.
  • The demonstration of the developed design techniques on industrial examples included an automotive muffler and a rail, the emphasis being on exterior noise reduction in both cases.

The responsibilities included the modal analysis of the different industrial structures and further development of a sensitivity-based finite element model updating program for large structures and its application to a rail fastening system with emphasis on exterior noise reduction.
