摘要
推导了 Maxwell模型粘弹性输流管道的振动方程 .对简支 Maxwell模型粘弹性输流管道探讨了其动力特性和稳定性问题 .计算结果表明 ,松驰时间及质量比对其动力特性和稳定性有显著影响 .
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.
