A Review on Structural Configurations of Magnetorheological Clutch

Abstract

Abstract:: In recent years, with the development of "smart materials", magnetorheological fluids have been widely used in the fields of mechanical transmission, aerospace, construction, and medical treatment because of the unique rheological properties that can occur under the action of an applied magnetic field. Magnetorheological clutches with magnetorheological fluid as the working medium have the advantages of simple structure, low noise, fast response, and easy control compared with traditional clutches. In order to provide an overview of the issues encountered by magnetorheological clutches in their current applications and to summarize the optimization designs implemented to address these issues, with the aim of promoting the widespread application of magnetorheological clutches. The basic theory of magnetorheological fluid and magnetorheological clutch design method is introduced. The related patents of magnetorheological clutch structure design are reviewed. The characteristics and advantages of magnetorheological clutch in different working modes are summarized. This study introduces the basic theory of magnetorheological fluid. The problems existing in the application of magnetorheological clutch are explained. The characteristics of magnetorheological clutch based on shear mode, shear-extrusion mode and heat dissipation mode are described. The development trend of magnetorheological clutch is discussed. This paper provides an important basis for the design and application of magnetorheological clutch, offers specific guidance for improving the torque transmission capacity and heat dissipation capacity of magnetorheological clutch, and lays a theoretical foundation for the wide application of magnetorheological clutch in the future.
