CSEM Micro-Vibration Characterisation Facility Description and Validation

Abstract

This article presents the micro-vibration characterisation facility recently developed by CSEM in Neuchâtel, Switzerland, its main specifications and several use cases. The facility consists of a custom-designed multicomponent dynamometer with very high sensitivity, capable of measuring in the mN range; high stiffness, with first eigenmode above 2 kHz; and low-noise signal conditioning and acquisition system. Several use cases are then presented to illustrate the capabilities of the facility, including the micro-vibration characterisation of a magnetic bearing reaction wheel demonstrator developed by Celeroton AG, the modelling and correlation of the micro-vibrations exported by a stepper motor, and of MeteoSat Third Generation’s Corner Cube Mechanism (MTG-CCM).
