连续线性-混沌混合隔振装置设计与研究

摘要

根据混沌隔振原理设计出连续线性-混沌混合隔振装置,该装置能够产生强非线性,其线性部分、非线性部分与模型几何尺寸相对应,并且两者完全区分开.在实验中两者均易于调节,这大大增加了该装置在工程中的应用前景.并利用数值计算对特定参数下的隔振装置在简谐激励力作用下的运动特性进行分析,分析结果表明该装置能够产生混沌运动,且具有很好的隔离线谱的能力.%A continuous vibration isolation system was designed, including a linear part and a highly nonlinear part corresponding to the model geometry. Both parts can be completely separated and easy to be adjusted in the experiment. With specific parameters of the vibration isolation system under harmonic driving forces, the dynamic characteristics of the system were numerically analysed. The results show that the system can generate chaotic motion, and has a good ability in line spectrum reduction.
