磁流变纤维骨架阻尼增强型阻尼器研究
Research on Magnetorheological Fiber Skeleton Damping Enhanced Damper
摘要
Abstract
To enhance the shear properties of magnetorheological grease and improve damping force output of damping devices,the effect of cotton fibers on the shear enhancement of magnetorheological grease is investigated.Magnetorheological grease with different fiber cotton mass fractions is prepared and tested on a rheometer.The experimental results show that the maximum shear stress of composite fiber magnetorheological grease increases with increasing fiber mass fraction.A shear magnetorheological damper is designed and manufactured based on composite material,the damper has the advantages of low amounts of magnetorheological materials and low sealing requirements.The damping characteristics of the magnetorheological damper experiment showed that under a current of 1.6 A,the maximum damping force of the magnetorheological grease with a cotton fiber mass fraction of 1.5%can reach 99.5 N,which is 23.8%higher than that of the magnetorheological grease without cotton fiber addition.This indicates that the damper using composite fiber magnetorheological grease has better damping force output.关键词
