Abstract
Transverse vibrations of axially moving beams with multiple concentrated masses have been investigated. It is assumed that the beam is of Euler–Bernoulli type, and both ends have simply supports. Concentrated masses are equally distributed on the beam. This system is formulated mathematically and then sought to find out approximate solutions. In case of three-to-one internal resonance, analytical solutions are derived by means of method of multiple scales (a perturbation method). It is assumed that axial velocity of the beam is harmonically varying around a mean-constant velocity. Steady-state vibration characteristics are investigated from the amplitude-phase modulation equations. Then, the effects of both magnitude and number of the concentrated masses on nonlinear vibrations are investigated numerically in detail.
