基于ANSYS软件和CFX软件的双向隐式交错迭代法对超空泡射弹尾拍运动过程中的流固耦合响应进行了研究，结构响应仿真采用有限元法、流场仿真采用分相流模型和SST湍流模型，重点比较分析了流固耦合作用对射弹运动姿态和流体动力的影响，给出了尾拍过程中弹体应力的变化规律。

Based on the staggered solution procedure of ANSYS and CFX software,the fluid structure coupling response of projectile during tail-slapping has been researched.Structural response was simulated by using FEM and flow field was simulated by using inhomogeneous model and SST turbulence model.Finally,the influences of fluid structure coupling effect have been analyzed and the change law of body stress has been given.
