| 摘 要： | 数值模拟了一类两自由度碰撞振动系统的概周期碰撞振动和混沌碰撞振动,通过调节正弦外加驱动力法控制该系统的混沌冲击振动.在适当的系统参数条件下该类系统呈现概周期碰撞振动,参数的变化导致概周期碰撞振动通过锁相或磕碰转迁为混沌碰撞振动.仿真结果表明通过调节正弦外加驱动力可将系统的概周期碰撞振动和混沌碰撞振动控制到稳定的周期碰撞振动.

| Abstract: | Quasi-periodic impact motions and chaotic impact motions of a two-degree-of-freedom vibratory system are investigated by numerical simulation.And chaotic impact motions of the system are controlled by the method to adjusting the sine periodic force.Under the suitable system parameter conditions,the system can exhibit quasi-periodic impact motion.The variety of the system parameters can result in the process from quasi-periodic impact motions via phase locking or chattering to chaotic impact motions.The results from numerical simulation illustrate that quasi-periodic impact motion and chaotic impact motions of the system can be controlled to stable periodic impact motions by adjusting the sine periodic force. |
