试论输液管道的振动和稳定性

本文从理论上探讨置于弹性基础上、受轴向力的输液管中流体诱导管柱的振动,导出了确定输液管振动的频率方程,讨论了管内流体和轴向力对输液管的振动和稳定性的影响,给出了确定临界压力和流速的理论公式。

STUDY OF VIBRATION AND STABILITY OF FLUIDCONVEYING PIPES

This paper theoretically discusses the vibration of fluid induced pipes with axial drive in the range of elastic properties, and derives an equation which decides the vibration frequency of fluidconveying pipes. This paper also investigates the effect of fluid and axial force on the vibration and stability of flowing pipes, and obtains a theoretical formula of deciding the critical pressure and velocity.
