摘要：

The stability of periodic motions (nonlinear normal modes) in a nonlinear two-degree-offreedom Hamiltonian system is studied by deriving an approximation for the Poincare map via the Birkhoff-Gustavson canonical transofrmation. This method is presented as an alternative to the usual linearized stability analysis based on Floquet theory. An example is given for which the Floquet theory approach fails to predict stability but for which the Poincare map approach succeeds. © 1980 by ASME.
