Abstract :
[en] The objective of this paper is to study the effect of structural dissipation on the dynamic response of tape springs using experimentally-validated finite element models. In order to reach this goal, an experimental set-up is built. It consists of two tape springs connected to a fixation support and a dummy panel. The data are collected through a force plate and a 3D motion analysis system. The post-treatment of the experimental results and a comparison with a finite element model show that the Kelvin-Voigt model gives a fair approximation of the structural damping for small oscillations, however, more advanced model should be considered in future works for a better understanding in case of large displacements.
