Influence of Metro Traction Drive System on Bogie Vibration

Zusatztext

The book analyzed the harmonic of the SPWM inverter and traction motor. In Simpack simulation software, subway train model is established, with motor, rotor, big gear and small gear and so on in metro traction electric drive system. In the Simulink simulation software, traction motor direct torque control model is established, and electromechanical coupling model is established by using the software co-simulation. Simulation analysis is conducted under constant speed condition of 60 km/h, finding that 12 times rotor fundamental wave frequency have a great effect on the vibration of the bogie.
