Abstract
This paper dels with the transverse vibration of non-uniform rotating beams, by means of the differential quadrature method (DQM). The formulation is based on the Timoshenko beam theory, wich takes into account the inertia forces due to the transverse translation together with the constributions of shear deformation and rotatory inertia. The application of the differential quadrature method is demostrated by investigating the natural frequencies. The results ara compared with published results given in the open literature and with values obtained by the authors using a finite element code. The proposed method offers a direct and efficient procedure to analyze the natural vibration of non-uniform rotating beams with very good accuracy.
