摘　　要：采用Fluent和有限元软件Ansys对某鳍翼外部流场和结构响应进行了流固耦合分析,其中流场计算采用k-ω湍流模型和RANS方程,结构计算采用弹性力学结构力学方程。通过变形和应力分布表明:在流固耦合作用下,鳍翼最大位移发生在翼梢部,鳍翼根部接触处存在明显应力集中现象。Fluent and ANSYS are used to analyze and calculate the external flow and structural response of a certain stabilizer fin. The turbulence model of k-ω and the RANS equation are used to calculate the external flow. The elastic mechanics and structure mechanics equations are used to calculate the structural strength. The deformation and stress distribution indicate that the maximal displacement of the stabilizer fin occurred in fin＇s tip under the fluid-solid interaction effect, and the stress concentration occurred at the contact place of fin root.
