英文摘要：
In this paper, the nonlinear dynamical characteristics for transverse vibrations of axially moving viscoelastic belt were investigated. The governing equations for the viscoelastic moving belt were derived in three-dimensional space. The method of multiple scales and the Galerkin＇s approach were applied directly to the partial differential governing equation of motion to obtain four-dimensional averaged equation. The results of numerical simulation demonstrate that there exist the periodic and chaotic motions of the axially moving viscoelastic belt.
