Abstract
This article presents the overhaul of the microvibration characterisation facility recently developed by CSEM in Neuchâtel, Switzerland, for the microvibration susceptibility analysis of space payloads. The upgraded configuration of the facility is composed of two decoupled granite masses over pneumatic isolators, over which a modal shaker on the one hand, and a suspension structure, on the other, are fixed. A suspended platform over which a set of accelerometers and the test specimen are fixed has been designed to minimise the effect of the different bending modes on the measurement. The first characterisation test results are presented showing the capabilities of the test equipment, enabling the sensitivity analysis up to 0.2 g accelerations on a frequency range of 30 to 2000 Hz with a high precision amplitude control a minimal harmonic distortion.
