| 摘 要： | 计算流体动力学方法（CFD）已经成为空气动力学领域重要的计算方法。利用该方法进行机翼模型Naca0012的数值模拟，包括计算模型的气动力系数以及气动导数。采用了效果很好的新型网格控制算法，通过自有程序处理流固耦合边界问题以及商用软件的求解器模块进行整体区域的数值计算。在证明了方法的有效性之后，又通过多种振幅奈件下的数值模拟结果，对以往广泛采用的理论方法的有效性进行了探讨，研究了机翼模型气动导数随振幅变化而变化的情况。

| Abstract: | CFD method has been an important method for aerodynamic analysis. The paper used CFD method to do numerical simulations of Naca0012 airfoil model, and got its aerodynamic coefficients and flutter derivatives. The paper gave out a new effective mesh control method, used self- owned codes and ANSYS- CFX solver to handle fluid- structure interaction. After proving the method was effective through comparisons between theory and CFD, the paper progressed numerical simulations for flutter derivatives identifications using many different force vibration amplitudes. Through these results, the paper discussed the applicable range of Theodorsen theory and the changing trends of flutter derivatives. |
