Design of Magneto Rheological Fluid Testing Device
Abstract: Magneto rheological (MR) fluid is an intelligent rheological material with peculiar performance. Excellent features like fast response, precise controllability, small energy and wide working temperature range make MR fluid technology develop rapidly and be applied successfully in various fields, such as automobile engineering, aeronautics and aviation, robotic engineering, hydraulic engineering, physical exercising apparatus，watercraft engineering and armament control etc. In the past several decades, the MR fluid has attracted much attention of researchers in fundamental science areas, such as physics and chemistry, and in engineering areas such as materials science and engineering, mechanical engineering and civil engineering. The design process of a testing device for MR fluid is introduced in the article, including choosing a motor, designing of transmission, controlling shear gap of MR fluid and designing of all kinds of support elements. Moreover, theoretical calculating and finite element simulation of magnetic field is conducted.
