我们使用的发展Liapunov的第二种方法来研究的局部和全局稳定性的平衡位置通过管道输送流体。管道两端简支，分析包括一阶（结构）非线性。主要结论是，与线性分析和最近的非线性数值研究的建议相反，在这里所研究的方程的情况下，持续的颤振运动是不可能的。
We use a development of Liapunov’s second method to study the local and global stability of the equilibrium positions adopted by a pipe conveying fluid. The pipe is simply supported at both ends and the analysis includes first-order (structural) nonlinearities. The major conclusion is that, contrary to the suggestions of linear analyses and of recent nonlinear numerical studies, sustained flutter motions are impossible in the case of the equation studied here.
