Analyses of the reaction forces (sample plot)
Analyses of the reaction forces (sample plot)

  • Planning, performance (at the Space Test Center IABG) and evaluation of vibration tests for ceramic (HB-Cesic®) star sensor bracket for Meteosat Third Generation Satellite
  • Performance of qualification as well as acceptance testing for flight models
  • Sine and random vibration tests
  • Experimental approximation of interface loads (forces/moments) based on a reduced mass matrix (Guyan reduction of FE model to the acceleration sensor positions) and the measured accelerations for sine as well as random vibration tests (mass operator method, see ECSS-E-HB-32-26A)
  • Computation and verification of notching profiles based on the approximated interface loads (see above) for sine and random vibration tests
  • Corellation of test results with FE analyis results
