摘要

本文研究了一个经典系统在非保守载荷作用下的参数振荡问题——含流动液体的柔性管道。参数对系统的影响是由流体流量的可变性决定的。根据Floquet-Lyapunov理论，用单矩阵法研究了管道平衡直线形式的稳定性。本文主要研究了参数效应的特性对管道稳定边界位置的影响，假设流量与某一常数，特别是幅值和频率存在谐波偏差。

Influence of Flow Velocity Variability on Pipeline Stability Boundaries

The paper considers parametric oscillations of a classical system under nonconservative loading—a flexible pipeline with a flowing liquid. The parametric effect on the system is determined by the variability of the fluid flow rate. The stability of the rectilinear form of the pipeline equilibrium according to the Floquet–Lyapunov theory is investigated by the monodromy matrix method. The main focus is the study of the influence the characteristics of the parametric effect have on the stability boundary position of the pipeline, assuming a harmonic deviation of the flow rate from a certain constant, in particular, the amplitude and frequency.
