Shear Yield Stress of Magnetorheological Fluids between Characteristic Surfaces of Different Materials

CODEN: JTEVAB

Abstract

Magnetorheological fluids (MRFs) have a wide range of applications in automotive and other industrial fields. As one of the main performance parameters of MRFs, static yield stress is the demarcation point of solid–liquid performance conversion. Therefore, yield stress is important to the study of MRFs. In this work, a new type of MRF testing device was designed. Three types of material blocks, namely, steel, copper, and aluminum, were tested to determine wall slippage using MRF-122E and MRF-132D. The results indicate that the best pulling blocks were the 1-mm copper rectangular channel and the 2-mm aluminum triangle channel. Identity distance was also tested, and the result indicated that the 1-mm copper pulling block and identity distance of 5-mm curve were nearest to the Lord Corporation yield curve with a maximum relative error within 5 %.
