摘      要：A magnetorheological fluid(MRF)is a smart composite suspension composed of nonmagnetic liquid and soft magnetic *** fluids can considerably influence the performance of MRFs;therefore,to investigate the effect of carrier fluids on MRFs,an SO/IL-MRF was prepared by mixing an ionic liquid(IL)with silicone oil(SO)in this *** types of MRF samples were prepared for experiments(pure SO,pure IL,and SO/IL).According to the experi-mental results,the SO/IL-MRF has better sedimentation stability than those based on pure SO and pure ***,three methods were used to determine the shear yield stresses of the *** SO/IL-MRF achieved a higher shear yield stress than those of the other two because a network structure is formed between the ionic fragments and the molecular chains of the SO in the SO/*** increases the movement resistance of the particles in the carrier fluid,and it is unlike the mechanism of the IL-enhanced *** work provides new ideas for improving the MRF performance.
