| Summary: | In order to study the temperature characteristics of a corrugated Magnetorheological Brake(MRB) applied to the vehicle under the strong coupling of magnetic fluid thermal field， the finite element analysis models of magnetic fluid coupling and thermal fluid coupling are established. The magnetic field distribution， temperature distribution under steady non-braking condition， and the transient temperature distribution under normal braking， emergency braking and frequency interval braking conditions are obtained by using direct sequential coupling method. The results show that the temperature distribution of corrugated MRB is nearly uniform under steady non-braking condition， while the maximum temperature under normal braking， emergency braking and frequency interval braking conditions are 92.4 ℃， 111.2 ℃ and 80.4℃ respectively， the temperature in the brake clearance shows a tendency of rising first and then falling. With the increase of excitation current， the maximum temperature of MRB device gradually increases in the process of breaking， but， its rising range is smaller and smaller. The results can provide reference for the design and application of MRB. |
