Studying on the Magnetorheological Fluids and its Rheometer

Abstract:

This paper presents a magnetorheological(MR) rheometer which consists of a pair of rotating parallel disc, step motor, the signal collecting device, computer software for dynamic analysis etc.. In order to assess the performance of the MR rheometer, high-order spectrum analysis tools are used. The theoretical and experimental results indicate that the rheometer is useful to test the dynamic charicteristics of the MR fluids and the high-order analysis might be helpful to describe MR rheometer dynamic characteristics. The measurement and analysis process based on virtual instruments are automatically controlled by computer in this paper.
