| 摘 要： | 经典模型下的2机系统在扰动消除后具有哈密顿系统特性。如果它能在首次正向摆动和首次反向摆动中保持有界，则将永远保持周期运动，但该系统在交变激励下则可能发生貌似无规律的混沌运动。对于经典模型下的3机系统，在瞬时扰动结束后，即使不再存在周期性激励，只要系统的时间响应曲线并非理想的两群动态，就会发生混沌现象。推导了经典模型下3机系统发生再同步混沌的条件，同时从理论和仿真两个方面揭示这些现象的本质。

| Abstract: | A 2 - machine system with the classical model is a Hamilton system.If the system does not lose stability during the first forward swing and the first backward swing,it will be stable for all other swings and keep the periodical m otion. However,the 2 - machine system may behavior chaotically under a sm all periodical- like excitation,as well as a multi- m achine system without any excitation.The analytical conditions of com ing into being chaos are derived for a3- m achine system,and mechanisms of the chaos of m ulti- machine systems are uncovered.Sim ulations are also given to confirm this analytical study.
