Dynamic stability of pipes conveying fluid
Web摘要： Considering the jointed influences of outer fluid damping, external steady current, internal flow, axial force, inner pressure and fluid mass ratio on the ciscoelastic pipes conveying fluid, a new numerical method, the Differential-Quadrature Method (DQM), was attempted to analyze the dynamic stability of submarine fluid pipeline under the effect … WebThe paper deals with the vibration and dynamic stability of cantilevered pipes conveying fluid on elastic foundations. The relationship between the eigenvalue branches and corresponding unstable modes associated with the flutter of the pipe is thoroughly investigated. Governing equations of motion are derived from the extended Hamilton’s …
