Annotation | The article is devoted to investigation of a pipeline dynamics, which is flexible hollow rod with flowing liquid. The explored model is reduced to investigation of stability of trivial equilibrium of nonlinear system of ordinary differential equations by the Galerkin method. The parametric area is constructed, that provides asymptotic stability of the approximate solution of the explored model, by Routh–Hurwitz stability criterion |
Keywords | dynamic stability of flexible pipeline, Galerkin method, Lyapunov's asymptotic stability, Routh–Hurwitz stability criterion |
