Abstract
This paper deduced the eigen-equation of viscoelastic cylinder with translational spring and rotational spring supported at both ends constituted by Kelvin's model in axial flow, and obtained the dimensionless frequency of the first three mode by Matlab program. The curves of the real and imaginary parts of the first three order dimensionless complex frequencies with dimensionless flow speed were developed when mass ratio and dimensionless delay time were constant, and dimensionless translational spring stiffness and rotational spring stiffness were changed.Also, the influence of dimensionless spring stiffness on dynamic characteristics of the viscoelastic cylinder was analyzed.关键词
