| Abstract: | The braking mechanism of a new auxiliary braking systems(permanent magnet retarder) is analyzed.The computation model of magnetic circuit is proposed.The solving problem of eddy current fields in the moving conductor is induced by the Maxwell equation.The analysis model is established and finite element method is used to analyze magnetic field.The analysis result of finite element method is compared to simulation measurement.The analysis model and the computation method in this paper are effective methods.The methods can be used in engineering practice. |
