Parametric Study of a Hybrid Mathematical Model of an Electromagnetic Systems with a Magnetorheological Fluid

Abstract

Electromagnetic devices with the magnetorheological (MR) fluid (mechanical devices such as clutches, seals, shock absorbers, vibration dampers, valves, brakes, seismic vibration dampers, body armor, actuators) are effectively used in various fields of production. They are easy to manage, fast, and are easily integrated into smart systems. The study of these devices, the construction of mathematical models, and the study of the nature of changes in operating parameters are important and urgent tasks. A hybrid mathematical model is presented, compiled for an electromagnetic brake with MR fluid, when the magnetic particles of the MR fluid have the shape of a cube and a sphere. A parametric study of the model is carried out. The dependences of the parameters characterizing the operation of the system on other parameters are obtained. Based on the results of the analyses, it is concluded that the model is adequate, i.e. it corresponds to the physical phenomena in the electromagnetic system under study. The methods and the principles of drawing up a hybrid mathematical model can also be successfully applied to electromagnetic devices with MR fluid of other types. The model can be used in the processes of studying the performance characteristics of brakes and designing new systems by using both classical methods and modern machine learning methods.
