| Abstract: | Considering the floating system pitching and sway motion, internal fluid flowing and external wave load, the vibration equation of marine riser is established. The finite element method is implemented to solve the matrix equation of equilibrium. Influence rules of pitching and sway motion on the dynamic respose of the marine riser is analyzed. |
