Abstract
In this paper, the in-plane rotating hub-beam system is mainly investigated considering effects of the hub. By applying the extended Hamilton’s principle and the Galerkin method, the governing equation of motion of the hub-beam system is derived. The hub-beam rotary inertia ratio is investigated to reveal its effect on the frequency characteristics of the rotating hub-beam system. Through the frequency analysis, it is shown that the natural frequencies of different orders vary between those of the clamped and the pinned boundary conditions at the connecting point between the hub and the beam. Finally the figure of connecting rigidity is plotted to show the variation.
