摘要
基于磁流变液的Bingham模型,分析了磁流变液在偏心圆筒中的流动,根据一维雷诺方程,建立了磁流变液在偏心圆筒中的剪切应力方程,并对剪切应力在偏心圆筒中产生的制动转矩方程进行了推导,分析了偏心圆筒磁流变制动装置的制动时间。结果表明:制动器是偏心结构,会对两圆筒之间的磁流变液进行楔挤压,由于挤压强化效应,偏心后的剪切应力和转矩比未偏心时分别提高了9%和8%,并且剪切应力和转矩都随外加磁场增加而增大;同时制动时间缩短了10%。
In this paper,the Bingham model of the MRF based on the analysis of the flow of MRF in eccentric cylinder,based on the one-dimensional shear Reynolds equation,established MRF in eccentric cylinder stress equation,and the she-ar force generated in the braking torque equation of eccentric cylinder is investigated,analyzed the braking time eccentric cylindrical magnetorheological brake device. The results showed that： the brake is an eccentric structure of MRF between the two cylinders of wedge extrusion,the extrusion strengthening effect,shear stress and eccentric torquethan non eccentricwere increased by 9% and 8%,and the shear stress and torque with magnetic field increasing; at the same time,shorten the braking time 10%.
