Passive stability control of hanging articulated pipes using an additional mass
Résumé
Depending on their physical characteristics, freely hanging articulated pipes can undergo divergence-or flutter-type instability above a critical velocity of the flow they conveye. The effect of adding a point mass, and more precisely influence of the mass magnitude and location, on the stability of such pipes is investigated by means of a linear analysis. It is found that this additional load can have a stabilizing or destabilizing effect depending on its location along the pipe and that the effect is all the more important as the mass is high. The influence of the mass on the shape of the destabilized linear mode is also discussed.
