Periodic and chaotic oscillations out of plane for viscoelastic axially moving beam
In this paper, periodic and chaotic oscillation out of plane are investigated for viscoelastic axially moving beam. The Kelvin viscoelastic model is chosen to describe the viscoelastic property of the beam material. Firstly, the nonlinear governing equations of out-of-plane motion are established by using the Hamiltons principle. Then, based on three-term Galerkins discretization, the governing equations of motion are simplified to ordinary differential equations with six-degrees-of-freedom. The bifurcation diagram and phase portraits are given to capture the systems dynamical behavior. From numerical simulations, it is indicated mat the periodic, quasi-periodic and chaotic motions occur in the out-of-plane vibrations of the axially accelerating viscoelastic beam.
