Abstract
The dynamic characteristics of a spinning Timoshenko beam are investigated by using the differential quadrature method (DQM). The beam is subject to any combination of free, simply supported, clamped, and elastically supported boundary conditions. The weighting matrices in the differential quadrature formulation are modified to incorporate classical boundary conditions of the beam, whereas boundary conditions of elastic supports are incorporated into the discretized equations. Numerical results of the spinning Timoshenko beam obtained by the DQM are compared with the exact solutions or results obtained by the finite element method. The results show the high accuracy and efficiency of the differential quadrature method.
