二元机翼颤振的分叉点类别的判定

ON BIFURCATION POINTS OF AIRFOIL FLUTTER IN INCOMPRESSIBLE FLOW

  • 摘要: 应用中心流形理论将二元机翼颤振这一四维系统降为二维系统,用后继函数判别法对分叉点的真假中心及稳定性问题进行了分析.

     

    Abstract: The bifurcation points of airfoil flutter system in incompressible flow are investigated in this paper. The theory of centre manifold is first used to reduce the flutter system to a two-dimensional one. Then the type and stability of the bifurcation points are analyzed by utilizing the method of succeeding function.
