摘要
文章基于混沌隔振原理,利用Duffing系统在混沌状态下的特殊性能进行隔振,通过对周期激励Duffing系统的相图、全局分岔图、庞加莱映射图的分析,说明了混沌的存在,以及混沌运动与各参数之间的关系,并给出了特定Duffing系统的混沌隔振效果.
Based on chaos vibration isolation theory,the Duffing system is used in the chaotic state of the special performance of vibration isolation.By analyzing periodically excited Duffing system phase diagram,global bifurcation and Poincaré maps,it shows the existence of chaos,as well as the relationship between each parameter,and a specific vibration isolation effect of the chaotic Duffing System is given.
