摘要	Thedynamic characteristics of deepwater riser usually present serried modes withlower frequencies, because structural flexibility is very large due tohigh aspect ratio (ratio of length to diameter of riser).Moreover, in practice flow velocity usually distributes non-uniformly along theriser length. A coupling model, for multi-mode VIV (vortex-induced vibration)of slender riser experiencing non-uniform flow, by means of finiteelement simulation combined with the hydrodynamic model taking account ofthe interaction between fluid and structure in time-domain, is proposed.VIV responses of slender risers respectively in uniform, stepped andshear flow are explored. Satisfied agreements with experiment results areobserved. Additionally, based on the numerical simulations effects of reducedvelocity and modal energy on modal weight are explored. Wenote that for case of multi-mode vibration the participating modestend to distribute by groups.
