NONLINEAR DYNAMIC BEHAVIOR OF VISCOELATIC TRANSMISSION BELT*
Abstract:
The nonlinear dynamic responses of viscoelastic axially transmission belts are investigated and the Kelvin viscoelastic
differential constitutive model is employed to characterize the
material property of belts. The generalized equation of motion is obtained for a viscoelatic axially transmission belts with geometric nonlinearity first, and then is reduced to be a set of second-order nonlinear ordinary differential equations by applying Galerkin’s method. Finally, the effects of viscosity parameter and elastic parameter and the moving velocity of the belts on the transient responses are investigated by the research of digital simulation.
