| Abstract: | This paper presents a linear track eddy current braking system scheme that suitable for EMUs.The action mechanism is analyzed,and the mathematical model is established for the eddy current braking system.According to the control principle of eddy current braking system,combining the distribution relationship of regenerative braking,eddy current braking and air braking during the braking of EMUs,the simulation model of eddy current braking system is established by MATLAB software.The effect of excitation current and air gap against eddy current braking force is obtained.Through simulation analysis,the appropriate excitation current and air gap value are obtained.It provides a theoretical basis for the application of eddy current braking system on EMUs. |
