A Method for Calculating Heat Energy and Braking Moment of Automobile Electromagnetic Retarder with Skin Effect

摘要

The mechanical structure and working principle of automobile electromagnetic retarder is analyzed in this paper to study the impact of temperature rising and skin effect on the performance of electromagnetic retarder. Furthermore, a method of calculating the heat energy and braking moment of automobile electromagnetic retarder is given taking temperature rising and skin effect into consideration. This method helps providing theoretical basis for the optimal design of electromagnetic retarder as it demonstrates the interrelation among design parameters more accurately. The method is proved to be correct by comparing and analyzing the calculation result and test result of DHZ100 electromagnetic retarder.
