Paper Abstract

This study focuses on a fluid mechanics approach utilizing the Herschel-Bulkley constitutive equation to develop a theoretical model for predicting the behavior of field- controllable electro-rheological (ER) and magneto- rheological (MR) fluid dampers. The aim of this research is to provide an accurate theoretical model for analysis, design, and development of control algorithms for ER/MR fluid dampers. The Herschel-Bulkley quasi-steady analysis is extended to include the effect of fluid compressibility. The major advantage of the proposed model is its dependency on only the geometric and material properties of the device. The theoretical results are validated by an experimental study. It is demonstrated that the proposed fluid mechanics- based dynamic model can effectively predict the behavior of field-controllable fluid dampers.
