Experimental Research on the Heat Transfer Characteristics of Electrorheological Fluid Shock Absorber

Abstract

Abstract：In order to study the thermal conductivity of ER in shock absorber, the AL2O3 and TiO2 ultrafine particles silicone oil ER are prepared to the different weights and been researched by experiment. Experiment result indicated: in the 5 mm scope of the electrode plank, the voltage from zero to three thousand, the thermal conductivity of ER fluids go up linear with the voltage growing, but the range is smaller; from three thousand to four thousand and five hundred voltage, the thermal conductivity of ER fluids go up with the voltage quickly. Under the high electric voltage, the ultrafine particles are polarized, the plus and minus particles are drawn each other, the particles are put in order and increasing the thermal conductivity.
