摘要:
以悬架系统为例 ,对采用磁流变减振器半主动控制系统的的振动特性进行分析 ,与传统被动悬架系统相比 ,其性能好 ,且无须向系统输入能量。分析结果表明 ,采用较大的阻尼时 ,半主动控制系统可以在全频率范围内起到减振效果 ,磁流变减振器是一种有发展前景的可控减振环节
Abstract:
This paper takes suspension system as an ex ample to evaluate the v ibration isolation characterist ics of the semiact ively cont rolled system w hich adopts magnetorheolog ical shock absorber. Compared w ith the convent ional passive dampers, the semiact ive dampers are able to isolate at lower f requencies, and they also do not add any energy to the system. The result s show that for suff icient ly large damping rat io, semiactive dampers are able to provide isolat ion at all frequencies and mag netorheological shock absorber is a promising controllable vibration isolation unit .
