| Abstract: | Based on Kelvin model, a set of free vibration equations for viscoelastic beam were derived, and the analytical solutions to the natural frequencies were given for viscoelastic beam on Kelvin model. The vibration behaviors of viescoelastic beam were analyzed and compared. So the coefficient of the viscoelastic materials could be calculated. The results show that the method is accurate and reliable. |
