摘　　要：根据电磁学理论,建立了旋转转子盘在磁场中的受力模型,推导出了电磁缓速器制动力矩表达式。利用MATLAB仿真分析了气隙参数和线圈电流参数对缓速器制动力矩的影响,同时绘制了某型号电磁缓速器制动力矩特性曲线。制动力矩的理论计算结果与试验结果对比表明,两者基本吻合且变化趋势相同。A mechanical model of rotating rotor disk in the magnetic field was established and a calculation formula of braking torque of electromagnetic retarder was derived, based on the electromagnetic theory. The influence of air gap parameter and coil current parameter on electromagnetic retarder braking torque was analyzed by the MATLAB simulation, and the braking torque curve was drawn and the calculated result and test result were compared, which showed that the two results are basically identical, and they show a similar vibration trend.
