Based on physical meaning of Melnikov function,we establish a method to calculateperiod doubling bifurcation and discuss this kind of bifurcation of soft spring Duffingsystem and find that the result is analogous to subharmonic bifurcation,that is,perioddoubling bifurcation will appear if damping is small and amplitude of excitation is big.Thiscoincides with facts of physics. 相似文献
