Abstract
The evaluation methodologies for the flow-induced vibration instability of a long flexible beam due to the axial flow in confined narrow passage are reported. So far, we have proposed original analytical method for the flow-induced vibration instability of elastic beam subjected to axial flow in confined narrow passage. In this paper, by using this proposed analytical method, we have performed the parameter-studies on the dynamic stability of elastic beam subjected to axial flow in confined narrow passage. And we clarify the effects of support conditions of structures, structural damping, and fluid characteristics on the dynamic stability for safety dynamic design in industries.
