摘要
本文利用广义KB平均摄动法研究二次分叉问题.对于两个具有Van der Pol Duffing型耦合的非线性振子,二次分叉一般会导致稳定的拟周期运动.然而,对于某些特殊的调谐参数数值,二次分叉会导致周期多样性.
The problem of secondary bifurcation is studied in this paper by means of the generalized KB averaging perturbation method. Generally, a stable quasiperiodic motion can be caused by the secondary bifurcation in two coupled Van der Pol-Duffing nonlinear oscillators. Nevertheless, for some special values of detuning parameters periodic variety may occur due to the secondary bifurcation.
