Specification of the Random Vibration Spectrum for the MERTIS Bolometer
Home/ Projects/ Space/ Specification of the Random Vibration Spectrum for the MERTIS Bolometer
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
