| Abstract: | Bifurcations of airfoils with nonlinear pitching stiffness in incompressible flow are investigated. The equivalent linearization method which is practical in engineering is adopted for the analysis and numerical integration method is used as a standard of checking. Analytical solutions calculated by Hassard's asymptotic expansion method and averaging method with the aid of computer algebra system have confirmed the feasibility of the equivalent linearization method. |
