摘　　要：对所研制的矿物油介质和硅油介质磁流变体样品的零场粘度、磁流变性能、示功及速度特性进行了系统的测试和分析 ,并对其影响因素进行了详细的讨论。研制的磁流变体零场粘度小于 0 .5Pas(γ =81s- 1)且具有良好的粘温特性 ;磁流变体的剪切应力接近和超过 70kPa(B =6 0 0 0Gs) ;The off-state viscosity( η 0), shear stress( τ ) and on-state performance curve of magnetorheological fluid based on carbonyl iron powder, mineral oil or silicone oil were investigated, the influence factor on the rheology character were also discussed. The MRF developed own ideal comprehensive property( η 0<0.5 Pa s, τ 70 kPa), good temperature stability and performace curve.
