Stability of a cantilevered system of articulated pipes conveying fluid is studied theoretically and experimentally by considering models having two degrees of freedom. The system is nonconservative and becomes subject to flutter-type instability or divergence-type instability depending on the parameters of the system. Firstly the effect of an intermediate lateral spring support on the stability is investigated to show that an additional spring support at the tip end can destabilize the system. Secondly the combined effect of a spring support and a lumped mass is discussed to show that the stability analysis by neglecting internal damping may result in an erroneous flutter prediction, especially when a big lumped mass is attached at the free end of the nonconservative system. Finally a set of experiments was conducted to verify the theory. Agreement between theory and experiment was satisfactorily good.
