概要

• 論文の詳細を見る

• The lateral vibration of a flexible clamped-hinged pipe hanging vertically, which is parametrically excited by a time-dependent harmonic component superposed on a steady internal flow, is examined theoretically and experimentally. Using the nonlinear coupled equations for the axial fluid flow and the lateral motion of the pipe, it has been shown mainly that as the amplitude of the pipe deflection grows larger, the nonlinearity of the fluid force acting on the pipe limits the growth, resulting in a steady-state vibration. Furthermore, experiments were performed using a water-conveying pipe model. The experiments were in qualitative agreement with the theoretical ones.
