Abstract
Aiming at the forward design requirements of permanent-magnet eddy current recoil brakes(ECRB),an integrated design methodology was proposed by combining the recoil braking characteristic curve of anti-recoil mechanisms and the resistance characteristics of ECRB,achieving reverse-solving of structural parameters based on design specifications.Firstly,the recoil braking diagram corresponding to the ECRB was designed,and the desired braking force was obtained.By analyzing the design parameters and working point of the permanent magnet of ECRB,using the proportion of the overall size of the machine as a limitation,the design parameters can be calculated.According to a given set of design indexes,based on the parameter values obtained through the above design method,taking the smoothness of the braking force curve and the maximum recoil displacement as the optimization objectives,the dimensional parameters were further optimized.The optimization results were verified by finite element models.The optimized design parameters meet the design requirements and optimization expectations.Traditional eddy current damper design methods rely on analysis of resistance characteristic parameters,and require empirical parameter adjustments to approximately meet braking force requirements.The method proposed in this paper can directly derive key parameters from design specifications,and it can support multi-objective optimization design based on performance requirements,significantly enhancing design efficiency and accuracy.关键词
