| Abstract: | The transverse vibration characteristics of an axially moving viscoelastic plates are investigated.Based on Newton's Second Law,the motion differential equations of an axially moving viscoelastic plate were established.Dimensionless complex frequencies of an axially moving viscoelastic plate with four edges simply supported were calculated by the finite difference method.And we analyzed the effect of the viscoelastic modulus and the dimensionless axially moving speed to the transverse vibration characterist... |
