The lateral vibration of a flexible pipe, which is hung vertically and conveys fluid is examined theoretically and experimentally for the case where the upper end of the pipe is periodically excited. Using nonlinear coupled equations with respect to axial fluid velocity and lateral deflection of the pipe, the complex equation governing the amplitude and the frequency of the lateral vibration is derived, near the critical fluid velocity above which the lateral vibration is self-excited. Furthermore, the experiment was conducted with the flexible pipe model conveying water. The beat phenomena in the lateral vibration of the pipe, as predicted by the theory, was observed slightly above the critical fluid velocity.
