ABSTRACT = {Cantilevered pipe conveying fluid may become unstable and flutter
instability would occur when the velocity of the fluid flow in the pipe exceeds
a critical value. In the present study, the theoretical model of a cantilevered
fluid-conveying pipe attached by an inerter-based dynamic vibration absorber
(IDVA) is proposed and the stability of this dynamical system is explored.
Based on linear governing equations of the pipe and the IDVA, the effects
of damping coefficient, weight, inerter, location and spring stiffness of the
IDVA on the critical flow velocities of the pipe system is examined. It is shown
that the stability of the pipe may be significantly affected by the IDVA. In
many cases, the stability of the cantilevered pipe can be enhanced by designing
the parameter values of the IDVA. By solving nonlinear governing equations
of the dynamical system, the nonlinear oscillations of the pipe with IDVA
for sufficiently high flow velocity beyond the critical value are determined,
showing that the oscillation amplitudes of the pipe can also be suppressed to
some extent with a suitable design of the IDVA.},
