Shock and Vibration Tests and Evaluation for ExoMars Components

Home / Projects / Space / Shock and Vibration Tests and Evaluation for ExoMars Components

The shock produced by activation of a Frangi-Bolt is measured and the SRS is directly analyzed on site (OHB premises).
The resulting shock loads for neighboring components have been derived by similarity-heritage-extrapolation, following the methods proposed by ESA
- SRS ratio method
- Zoning procedure
- Test prediction based on modal properties derived by FEA
KRP has further proposed shock attenuation solutions for this project
For a different ExoMars component, vibration measurements were performed (at SGS). Two kinds of tests were done:
- Resonance search
- Identification of optimum operational frequency with respect to function (high vibration at a selected position) and shock loads (low SRS at the interface)
