| Abstract: | In this paper, the effects of forward speed on the lateral vibration of a slender structure in an infinite fluid are considered.
By equating the bending stress of the structure with the hydrodynamic force acting on it, the equation which governs the fluid-structure
interaction of a slender structure both vibrating and moving in water is obtained. Numerical results show that the influence
of forward speed on the vibration of a slender structure in water is significant. It behaves like damping, reducing both natural
frequencies and responses significantly. |
