摘要:

In order to overcome the problem of severe thermal decay of braking torque in sustained braking of conventional eddy current retarder and save energy, a novel structure of liquid-cooled self-excited electromagnetic retarder is proposed. The electromagnetic field and the braking performance of the retarder are analyzed with finite element method and numerical simulations on its transient flow field and thermal field are conducted by using finite volume method. The characteristics of the retarder are also measured on a test bench. The results show that the simulated results well agree with test data with a braking torque up to 1, 600N·m and its thermal decay less than 5% in continuous braking condition, meeting the requirements of heavy vehicles. ©, 2015, SAE-China.
