Assessment of Cable Models for Synthetic Mooring Lines

摘要

This study deals with the modeling of the static behavior of synthetic wire ropes. The objective is the determination of the validity domain of two analytical models (Costello and Labrosse) used to predict the overall axial stiffness. First investigations have been performed for isotropic material. The results of the two analytical models are compared with a three-dimensional finite element cable model, using a non-dimensional analysis. Next, Labrosse’s model is extended for synthetic fibers rope applications. Tests performed to obtain experimental stiffness measurements are then presented. Finally, predicted stiffness is compared to test results thus validating the analytical approach.
