Abstract:

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.
