Abstract
Self-excited vibrations of a pipe conveying fluid with an asymmetric spring supported end are explored theoretically and experimentally. The planar, nonplanar vibrations and beating phenomena of the lateral pipe vibration are occurred due to the flow velocity and the perturbed parameter of the spring support. Furthermore, the experiments were conducted with a silicon rubber pipe conveying water. The spatial motions of the pipe were measured by the image processing system, which was based on the images from two CCD cameras. The features of the self-excited pipe vibrations, which were predicted in the theory, were confirmed qualitatively.
