摘要
用二阶平均方法考察了一个带相差的三势能井Duffing系统的周期轨分支,包括主共振分支和二阶次谐波分支,并且得到了相差对分支动态的影响.
The bifurcations of periodic orbits of three-well Dulling system with a phase shift are investigated in detail. The conditions of the existence and bifurcations for harmonics, second-order subharmonics under small perturbations are given by using the second-order averaging method, and the influence of the phase shift on the bifurcations is also obtained.
