The Dynamic Behaviors of Pipe Conveying Fluid Considering Moment of Inertia by Finite Difference Method

根据Ｈａｍｉｌｔｏｎ变分原理，推导出了考虑转动惯量和剪切变形时输流管道的运动微分方程，用有限差分法分析了考虑转动惯量时输流管道的动力特性和动力稳定性。

Based on the Hamilton's variational principle, the motion differential equation of pipe conveying fluid in consideration of the moment of inertia and shear deformation is derived. The dynamic behaviors and stability of pipe conveying fluid considering moment of inertia are analysed by finite difference method.
