Based on the mathematical model of rod beam induced vibration in stationary fluid with Chen bounded domain, a numerical method for the stability analysis of the rod bundle is given. As an applied research, the characteristics and stability of the flow induced vibration of the bundles (4) in the axial flow of a bounded domain are analyzed. The effects of axial and transverse vibration modes
