摘要：
Bifurcations of airfoils with non-linear pitching stiffness in incompressible flow are investigated. The harmonic balance method, which is more practical, is adopted for the analysis, and numerical integration results are used as standards of checking. Analytical solutions calculated by asymptotic expansion method and averaging method with the aid of computer algebra have confirmed the feasibility of the harmonic balance method. © 1992.
