摘 要: 对定常空气动力作用下、含立方非线性刚度的二元机翼颤振系统的分叉点进行了研究.应用中心流形理论将四维系统降为二维系统。 The properties of bifurcation points of airfoil flutter with cubic nonlinearity in incompressible flow are studied.The centre manifold theory is used to reduce dimensions of the system. As a result,the type and stability of the bifurcation points in the reduced 2 dimension system can be determined by means of the formal series method.
