摘要：

Here, the software ANSYS was used to perform fluid-structure interaction characteristics analysis of a gas-liquid two-phase flow marine riser including modal analysis and dynamic analysis. Modal analysis was used to study change of vibration modes of the riser with and without fluid-structure interaction and effects of fluid boundary conditions on natural frequencies and modal shapes of the riser. Then, natural frequencies solved using simulation analysis were compared with those solved using DNV formula to verify the correctness of simulation. Dynamic analysis was used to study fluid-structure interaction vibration analyses in single direction and double ones, and contrastively analyze both of them considering effects of riser support mode and fluid boundary conditions on riser vibration. Finally, the vibration reduction measures for riser were proposed. The study results provided an important theoretical basis for optimal design and operation reliability of marine risers. © 2021, Editorial Office of Journal of Vibration and Shock.
