Abstract—This study focuses on simulating the heat generation in Magnetorheological Brakes (MRBs) during vehicle descent under standardized test conditions. The simulation results indicate that, under both test scenarios with slopes of 6% and 11%, the temperature generated in the MRB exceeds the permissible limits of the brake material. To address this issue, a cooling solution was implemented through thermal simulations using the numerical simulation software STAR-CCM+. Specifically, water jackets arranged around the brake casing and coils were used for cooling, resulting in an average temperature reduction of over 68% in both test scenarios. These findings highlight the potential for practical application of MRBs in actual vehicles by ensuring their thermal performance remains within safe operating limits.
