The traction control unit(TCU)is the core component of the traction drive system of urban rail vehicles.To achieve energy conservation,effi ciency improvement,and effective verifi cation in the TCU software development and upgrade process,the hardware-in-the-loop simulation of the traction drive system of urban rail vehicles is studied.According to the electrical topology of the traction converter,a hardware-in-the-loop simulation model of the urban rail traction converter,asynchronous motors,and vehicle body dynamics is established.Considering the different requirements of each part of the model for the simulation step,a multi-rate simulation architecture is designed.Combined with a network simulation system and automated test software,a complete hardware-in-the-loop simulation system is built.Finally,the automated test simulation results are compared with the actual unit test results to verify the effectiveness and correctness of the hardware-in-the-loop simulation system.
