This research deals with nonlinear stabilities of lateral vibration of a fluid-conveying pipe, which is supported with a spring at the end of it. It is theoretically examined that the spring hardness influences the nonlinear instabilities of lateral pipe vibration due to an internal flow, such as supercritical or subcritical instabilities. Moreover it is theoretically clarified that the amplitude of the initial disturbance effects on the stability of lateral pipe vibration in the subcritical region. That is, there are two stable pipe vibrations, which are different amplitudes and converge/diverge depending on the amplitude of the initial disturbance. Finally, the theoretical results are confirmed with the experiments, which were conducted with the silicon rubber pipe conveying water.
