Abstract

The characteristics of vibrational power flow in an endless elastic cylindrical pipe filled with fluid under forced vibration was investigated. The simple harmonic motion of pipe and the pressure field in the contained fluid were investigated by using the Flugge equation and Helmholtz equation respectively. The vibrational equation of this pipe-fluid system was then obtained by using the coupling between pipe and fluid. By using the Fourier transform and its inverse transform, the input power into this coupled system under a simply harmonic, linearly distributed driving-force, and the axial transmission of the power flow carried by the contained fluid as well as by the different pipe internal force were discussed.
