For the MERTIS Bolometer (MErcury Radiometer and Thermal Infrared Spectrometer, scientific instrument for the ESA Deep Space Mission BepiColombo) the random vibration loads have been specified using FE analyses:

  • FE modelling (MERTIS Bolometer model as well as model of respective optics structure)
  • Modal-analysis
  • Quasi-static loads
  • Random-vibration-analysis
  • Computation of the required notching for the random vibration tests
  • Specification of the random vibration spectra for the random vibration tests
