摘 要：Adopting carbonyl iron powder and silicone/mineral oil as suspend phase and dispersed phase separately,and silica,kaolin as lubricant additives,magnetorheological(MR)fluid was prepared by ball *** apparent viscosity of base oil and shear stress were measured on a modified rotational *** experimental results demonstrated that an appropriate viscosity of base oil contributed to the rheology of *** a small amount of thixotropy into MRF had little influence on zero-field viscosity,which facilitated the application of MRF to maintain adequate *** low shear rate conditions,the shear stress was improved by adding thixotropy to some extent,especially in the mineral oil-based magnetorheological fluid,in which the role of silica was superior to kaolin.
