Abstract

When used for spatial applications, electronic equipments undergo pyrotechnical shocks, for instance during the separation steps of the launcher vehicle stages or when the solar panels of a satellite are deployed. These shock environments are characterized by test specifications defined by shock response spectra. The frequency range usually extends up to 10 kHz and the acceleration amplitude exceeds in some cases several thousand g's at frequencies above 1000 Hz. The vibration resistance of electronic equipments is verified in laboratory conditions by reproducing similar pyrotechnical shocks. Usual laboratory test facilities such electrodynamic shakers or drop tables are not suitable to represent such severe shock environments. T
