Abstract:
Considering the nonlinear characteristics of submerged floating tunnel(SFT)cable and the lateral dynamic response of structure-fluid interaction(SFI), a nonlinear dynamic model equation of SFT cable was established in the time domain, the equation was solved by the secondary development of finite element software ANSYS, and the nonlinear dynamic characteristics of the SFT cable was analyzed under the action of lateral lift. The results show that the axial force of the cable and the maximum displacement of the middle part of the cable have a significant reduction with the increasing of cable pretension. The maximum displacement of the middle part of cable has a certain increase with the increasing uniform flow velocity without resonance, and it has a jumping develop with resonance. The maximum displacement of middle part of cable decreases with the increasing of cable length, but the axial force of the cable increases. The inclination of the cable has the similar effect on the displacement and the axial force, the axial force and the displacement increase at beginning and then decrease with the increasing of inclination. 9 figs, 16 refs.
