| Abstract: | To evaluate the bending performance of steel tube umbilical cable, an efficient 3D finite element parametrization model is established for steel tube umbilical cable, the beam elements are used to simulate all the components, line-line contact is set among the components in contact with each other to simulate the interaction, and Coulomb friction is used to simulate the friction behavior among the components. The validity of the finite element model is verified by the comparison of the analysis results of bending stiffness with the one of classical theory. Based on the model, the effect of different helical angles and friction factors on bending stiffness is analyzed. The analysis results can provide technical references for the detailed design and analysis of the body structure of steel tube umbilical cables. |
