Abstract :
[en] In the first part of the present paper, experiments carried out on IREQ laboratory cable test bench were described. One of the objectives of these experiments was to collect all the required data to validate the modelization of this cable test bench vibrating at its eigen frequencies. Conductor excitation was performed by a vibration shaker. In the present paper, the first modelization results are presented. The model used is a beam element model, with an average value of conductor bending stiffness. For certain of the simulations, some material damping was introduced through the use of a visco-elastic material. The vibration shaker is modelled by a harmonic force of adequate amplitude and location. The results obtained with this model put in evidence the impact of tension variations on such span length, which makes it difficult to obtain a resonance. Also, computed mode shapes are in good agreement with the reality, and time response of the model with a concentrated mass enabled us to reproduce some interesting observed phenomena.
