摘 要: 对不可压气流中二元机翼颤振系统的分岔点进行了研究.应用中心流形理论将四维系统降为二维系统。 The characteristics of bifurcation points of airfoil flutter in incompressible flow are investigated. The centre manifold theory is used to reduce dimensions of the system. The type and stability of the bifurcation points in the subsequent reduced two dimensional system are analyzed by the method of succeeding function. It is concluded that the three bifurcation points correspond to stable or unstable foci respectively.
