Vibrations of straight and curved composite beams: A review

Stability and oscillation characteristics of two-dimensional axially moving web have been investigated. The application of one-dimensional beam-like models of the web allows the identi1cation of instability regions and the estimation of the critical speed. For the beam material two di3erent models, i.e., Kelvin–Voigt and B # have been considered. The numerical solutions of full non-linear and linearized equations have been compared. The e3ects of axially travelling speed and the internal damping on dynamical stability of axially moving web have been studied in details. Our numerical studies of Kelvin– Voigt and Burger’s models show that both models give similar results for small values of internal damping and can be used to describe the dynamics of axially moving webs made from materials with internal damping coe7cient smaller than 3 × 10 −5 . For the materials with larger damping coe7cient the B # urgers model gives more reliable results. ? 2002 Elsevier
