摘要	Aiming at vortex-induced vibration (VIV) phenomena of high pressure drop type regulating valves, a high pressure drop regulating valve with combination of multi-channel labyrinth discs and multi-stage sleeves was designed. Based on CFD and the fluid-structure coupled modal analysis, inner transient flow field and structural modes of the valve were calculated to obtain its 3 typical open fluid flow cases, lift coefficient's time domain and frequency domain characteristic curves as well as modal frequencies and modal shapes. The results showed that at 4 s time instant, with decrease in the valve's opening, the maximum flow velocity of fluid decreases, and large vortex in outer flow channel of the fourth-stage sleeve gradually forms small one; fluctuation of fluid lift coefficient during the valve being fully open is more violent than those during the valve having 70% and 40% openings, the 1st and 2nd order modal frequencies of the valve increase with increase in valve opening; the valve's modal frequencies don't fall in range of vortex shedding main frequency, the valve can't have VIV locking phenomenon. © 2020, Editorial Office of Journal of Vibration and Shock.
