【摘要】 在分析磁流变减振器工作模式基础上,结合汽车减振器的工作要求,分别完成了混合模式和流动模式磁流变减振器的结构设计,建立了两种模式下的数学模型并进行了相关的仿真研究,设计出了产品并进行了试验研究。比较分析发现,二者阻尼力在低速时差异不大,但是在高速时差异较大。从工程实现和控制角度看,混合工作模式可以减少阻尼孔的堵塞并具有较大的可控倍数,其性能要明显优于流动模式减振器。通过试验证明,建立的模型、提出的设计思路和方法符合工程要求。更多还原

【Abstract】 Combined with the requirement of vehicles damper,two type of dampers were designed and manufactured by analyzing the two working pattern of MRF.The comparison between simulation and the experiment result shows that the difference of damp force is small in low speed and large in high speed.It is obvious that the performance of the mixed model is more excellent than the flow model.It has higher control rate and can reduce the jam of the damp hole in practice.It is certified that the magnetorheological fluid damper(MRD) model and the design idea and methods are correct and accord with the requirement of engineering.更多还原
