Abstract: In the present paper; a 3-D homogenized model for bean bundle in fluid is developed and formulated in terms of fluid velocity potential and displacement of beams as fundamental unknowns. It can be seen that the homogenized model is associated with a set of finite element equations in the form of a conservative gyroscopic system. Based on these equations, an algorithm for the modal analysis and the dynamic response analysis of the beam bundle is also given. It is found that both the displacement and the fluid pressure response of the bundle have a similar relation with time, but different amplitudes.
