摘　　要：在流体动力式声波发生器簧片哨工作状态下,研究喷射流喷击簧片的流固耦合过程。首先,根据流固耦合分离解法分别建立流体、固体的运动方程,并建立湍流模型。其次,建立仿真模型,并设置边界条件。最后,利用ANSYS-CFX双向流固耦合法计算簧片的动态特性:簧片振动的频率、幅值,簧片与水的瞬态耦合,以及簧片周围的流场变化。计算结果表明此簧片哨在工作状态下,其簧片做低幅、低频振动。When the hydrodynamic reed whistIe is in working conditions,research the FSI process of reed.firstIy,estabIished fIuid, soIid equations of motion based on the separation soIution about FSI,and created turbuIence modeI.SecondIy,created nu-mericaI modeI setting the boundary conditions.FinaI y,anaIyzes the dynamic characteristics of the reed by the use of two-way FSI ANSYS -CFX.IncIuding vibrating frequency,ampIitude of reed,transient coupIing by reed and water,and the fIow changed around the reed.The resuIts show that in working condition,the reed do Iow-ampIitude,Iow-frequency vibrations.
