Abstract

Natural frequencies of axially moving beams with fixed supports are analyzed based on the Timoshenko model by using the Galerkin method and the differential quadrature method. Numerical examples are presented to show effects of the related parameters on the frequencies, such as axial speed and stiffness. Results obtained with the differential quadrature and the complex mode methods are in good agreement, while the results obtained with the Galerkin method are slightly different.

Key words： axially moving beams; differential quadrature method; Galerkin method; natural frequencies; Timoshenko model
