原始语种摘要: Polytetrafluoroethylene (PTFE) micropowders were used to prepare PTFE-oil organogel. Carbonyl iron particles were dispersedin this organogel to fabricate magnetorheological fluids. The main aim of this paper is to investigate the influences on fieldinducedchains by non-magnetic microstructures inside these organogel-based MRFs. The field-induced anisotropy of MRFsbetween first normal stress differences to shear stresses and dynamic modulus reveal that organogel widen the non-Newtonian elastic range of MRFs as long as the non-magnetic particles content is appropriate. Both theoretical and experimentalresults of static and dynamic normal forces indicate that normal forces are influenced by magnetic and non-magneticmicrostructures comprehensively. The dynamic normal forces are lower than...
