摘要
为分析激励频率变化时,混沌隔振系统对特征线谱隔离效果的影响,设计双层混沌隔振系统,研究在不同激励频率条件下,混沌隔振系统对线谱的隔离能力。试验结果表明,激励频率对系统的隔振效果有较大的影响,在系统固有频率附近,线谱的隔离能力较差,在混沌隔振系统设计中,同样需要避开系统的固有频率。
In order to analyze the influence of excitation frequency on performance of chaos vibration isolation system（VIS）,an experimental setup was constructed.The experimental results showed that the excitation frequency has great influence on performance of VIS.In the region of inherence frequency of system,the line spectra in the radiated noise can not be reduced effectively,so in the design of chaos VIS,the inherence frequency of system should be avoided.
