摘要
In this study, a coupled model was developed of wind-induced vibration of a stack, based on an unsteady-flow theory and non-linear dynamics of the stack's heavy elastic suspended cables. Numerical analysis was performed to identify excitation mechanisms. The stack was found to be excited by vortex shedding. Once lock-in resonance occurred, the cables were excited by the transverse motion of the stack. Large-amplitude oscillations of the cables were due to parametric resonance. Appropriate techniques have been proposed to alleviate the vibration problem. (C) 1996 Academic Press Limited
