Abstract
The dynamic study of structures completely or partially immersed in fluids is necessary to ensure not only their stability but also the safety of their users. The present work treats the vibrations of a completely submerged beam subjected to sea wave excitations. The expressions of the external forces that the fluid exerts on the structure are found as well as the equation of the movement of the system. Using the numerical resolution, we show the accordance between the analytical and numerical results. A comparative study of the vibration amplitudes of the structure under the action of one and several waves was carried out. The stability study allows us to have a better insight into the dynamics of the structure. The influence of some hydrodynamic parameters, namely, the immersion height of the structure, the density of the fluid, and the nonlinear term, has been studied.
