Abstract: On the basis of dynamic behavior for axially moving viscoelastic plate with uniform
thickness and homogeneous, considering the varying thickness and inhomogeneous, the differential
equation of motion with variable coefficient for axially moving viscoelastic plate is derived. The
thickness and physical parameters of material for the plate is assumed to linear change along the
direction perpendicular to axially moving. The effective differential quadrature method is adopted, and
the effects of the axially moving velocity, thickness ratio and three inhomogeneous variation
coefficients on transverse vibration characteristics and stability of viscoelastic rectangular plate with
four edges simply supported are analyzed.
