摘要针对高压降类调节阀涡激振动现象，设计多通道迷宫盘片和多级套筒组合高压降调节阀。基于计算流体动力学（CFD）和流固耦合模态分析法，计算调节阀内部瞬态流场及结构模态，得到其三种典型开度的流体流动情况，升力系数时域和频域特性曲线，以及模态频率和模态振型。分析结果表明：4 s时刻，随调节阀开度减小，流体最大流速相应减小，第四级套筒外部流道区域的大涡逐渐形成小涡。调节阀全开时流体升力系数波动比70%和40%开度时更为剧烈，一阶模态频率、二阶模态频率均随开度的增大而增大。调节阀模态频率没有落在漩涡脱落主频率范围内，调节阀不会发生涡激振动锁定现象。

Abstract：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.

Key words： high pressure drop labyrinth sleeve computational fluid dynamics (CFD) transient flow field vortex-induced vibration (VIV)
