The Preparation of multifunctional shear thickening fluid and the application in shock absorber

Abstract

Abstract A multifunctional shear thickening fluid (MSTF) that exhibits both shear thickening (ST) effect and magnetorheological (MR) performance was prepared. The MR effect of MSTF was compared with magnetorheological fluid (MRF) when the CIP mass fraction varies from 10% to 70%. The results show that the MR effect of MSTF is higher than that of MRF obviously. Besides, the compression force and rebound force of the damper containing MSTF and MRF were tested and compared when the current was set as 0, 0.5, 1.0, 1.5, 2.0, 2.5 and 3A. When the CIP mass fraction is less than 30%, the forces of these two kinds of materials are almost the same at any current value. And as the CIP mass fraction is more than 30%, the rebound force of MSTF is obviously higher than that of MRF.
