Design methodology of permanent magnet eddy current brake and optimization based on the Stackelberg game theory

The permanent magnet eddy current brake (ECB) discussed in this paper are expected to brake a strong impact load for a large-scale machinery, and its design requirement is to brake smoothly within a given displacement limit. A design method is proposed to be able to design and calculate the based on the design requirements. According to the requirements of the brake displacement, an expected brake force can be calculated. Then, through the analysis of the permanent magnet operating point and the analysis and calculation of the design parameters, a reasonable design scheme that matches the prime design requirements can be obtained. When facing strong shock loads, in addition to satisfying braking requirements, different shock conditions can lead to different practical braking process. Making the corresponding braking process smoother can be regarded as an additional design objective, thus the design scheme obtained can be optimized in a certain range accordingly. A multi-objective optimization design of the ECB is carried out in combination with the Stackelberg game theory. After verifying the optimization results, it can be obtained that the given design and optimization methods are applicable and can satisfy the design and optimization objectives.
