| Abstract: | Based on the differental constitutive relationship of linear viscoelastic material,a solid-liquid coupling vibration equation for viscoelastic pipe conveying fluid is derived.The dynamic behavior and stability of simply supported viscoelastic pipes conveying fluid with Maxwell model are analyzed.It should be pointed out that the relaxation time of viscoelastic material with the Maxwell model has a remarkable effect on the dynamic characteristics and stability behaviors of the simply supported viscoelastic pipe conveying fluid with Maxwell moldel. |

| Keywords: | viscoelastic pipe conveying fluid stability relaxation time coupled-mode flutter |
