中文摘要：

针对磁流变减振器需要外部供电限制其应用范围的问题,基于磁流变减振器的工作特点和振动能收集方法的探讨,提出了一种馈能型（自主供电）磁流变减振器。根据该馈能型磁流变减振器的功能模块分析,研究了集成馈能装置的磁流变减振器的设计方法并确定了其结构参数,并设计了与馈能装置相匹配的电能管理电路。特别地,在频率1 Hz~3 Hz、振幅10 mm振动条件下,利用有限元软件Ansoft对馈能装置进行了输出电能仿真,然后进一步仿真分析了其输出电能使磁流变减振器产生阻尼力的大小。仿真结果表明,该馈能型磁流变减振器产生阻尼力变化范围为1 072 N~2 028 N,说明在低频、小振幅振动条件下,该馈能型磁流变减振器可以在无需外部供电的情况下改变自身阻尼特性。

英文摘要：

Aiming at the restricted application range of magnetorheological damper （MRD）with external power supply, based on the working characteristics of MRD and the investigation about harvesting energy from the vibration, a new type of Energy-regenerative MRD （ called self- powered MRD） was proposed. According to the analysis on function modules of Energy-regenerative MRD, the design methods of MRD inte- grated Energy-regenerative device was investigated to confirm their structure parameters, the electrical circuit was designed in accordance with Energy-regenerative device . Particularly,at the vibration condition of 1 Hz to 3 Hz frequencies and 10 mm amplitude, by utilizing the fi- nite element software Ansoft, the simulation about power output of Energy-regenerative was performed, then the capacity of damping force produced by MRD under power output of Energy-regenerative was simulated. The simulation results show that the Energy-regenerative MRD can produce 1 072 N - 2 028 N, at the vibration condition of low frequency and small amplitude, the energy-regenerative MRD is able to change its damping characteristics without external power supply.
