Original Abstract
This contribution is focused on the analysis of dynamic behavior of an elastic body moving in liquid. This paper presents a new approach to the solution that allows the separation of the structure and liquid from each other. The approach is based on the expansion of the solution into a series of eigenshapes of vibration. In addition, a new type of boundary conditions is presented that allows modal analysis and calculates the steady state or unsteady response. It is however necessary to perform some computational and experimental testing to verify this approach which is new. The cantilever beam vertically submerged in water was chosen as a test set up to represent a rotor. In the paper, some comparisons of computational and experimental analysis are presented. For this case a specific programme was created in MATLAB, where the curvilinear co-ordinates were chosen. The Bézier body was chosen for the description of the geometrical configuration and also for the approximation of the solution. For the experimental verification, a cantilever beam submerged under water was chosen
