Comparative Study of Natural Frequencies of Cubic Fixation Devices for Vibration Testing on Electrodynamic Shakers

This paper presents a comparative study of different cubic fixation devices used for vibration tests on electrodynamic shakers. The resonance frequencies are obtained experimentally and they are used to calibrate the finite element simulation model. After that, a new design is proposed in order to increase the frequency of its first vibration mode and improve its useful frequency test range.
