Abstract
Thispaper presents a Differential Quadrature Element Method for free transverse vibration of a robotic-fish based on a continuous and non-uniform flexible backbone with distributed masses (represented by ribs) based in the theory of a Timoshenko cantilever beam. The ef- fects of the masses (Number, Magnitud and position) on the value of natural frequencies are investigated. Governing equations, compatibil- ity and boundary conditions are formulated according to the Differ- ential Quadrature rules. The compatibility conditions at the position of each distributed mass are assumed as the continuity in the vertical displacement, rotation and bending moment and discontinuity in the transverse force due to acceleration of the distributed mass. The con- vergence, efficiency and accuracy are compared to other analytical so- lutions proposed in the literature. Moreover, the proposed method has been validate against the physical prototype of a flexible fish backbone. The main advantages of this method, compared to the exact solutions available in the literature are twofold: first, smaller time-cost and sec- ond, it allows analysing the free vibration in beams whose section is an arbitrary function, which is normally difficult or even impossible with analytical other methods.
