Abstract
By reviewing the research conducted on the eddy current braking system's analysis and optimization, it is observed that eddy current braking's physical characteristics are not studied in the automotive application, and its braking torque is not sufficient. In this paper, the governing equations of the braking torque of the eddy current brake with the addition of skin effect and heat are applied, and the results of the two basic and modified models are compared. Then the sensitivity analysis was performed by the finite element method. The analysis results show that by applying the skin effect and heat, the skin effect and heat, the braking torque increases and decreases, respectively. The sensitivity analysis results show the effect of the system's geometric, dynamic, and electromagnetic parameters and structural modifications on the initial value, peak value, and durability of the braking torque produced by the eddy current brake.
