Rheological damping of slender rods

Abstract: Efficient and accurate modelling of mooring and cable systems for Floating Offshore Wind Turbines are a key factor in the coupled dynamic analysis for the realistic assessment of such floating structures. In order to improve the modelling of the mooring and cable systems, a new extension of the slender rod finite element model proposed by Garret with the inclusion of rheological damping is presented. The model takes into account the damping produced for the rod material in both the axial and the bending forces… Show more

“…The quasi-dynamic model is an upgrade of the quasi-static model which uses the static solution of the catenary line, but updates the tension of the line based on an approximation of the dynamics of the line. The FEM model is based on the slender rod model, (Garrett, 1982), with the addition of the material stiffness, small strain assumption and material damping for both axial and bending deformations (Trubat & Molins, 2019) Both models are further detailed in this Thesis.…”

“…A numerical verification is performed in order to obtain the applicability of the proposed approach. The numerical verification consists of comparing the proposed model against a validated dynamic model (Trubat & Molins, 2019). The comparison is set for the simulations of a parametric study composed for two different chain sections and three different line shapes.…”
