Study on the method of traction motor load simulation on railway vehicles

Abstract

This paper on a method of traction motor load simulation on railway vehicles is from the proceedings of the 12th International Conference on Computer System Design and Operation in Railways and Other Transit Systems, held in Beijing, China, in 2010. The authors present an expression of the load torque of the traction motor, based on the physical model of the motor-wheelset system, the expression of the load torque of traction motor is drawn out. Focusing on two parts,the damping torque of the load torque and inertia loads, the authors propose separate control methods of a DC load motor electromagnetic torque. Following the principle that the acceleration time should be the same as the actual time, this model indicates how to reduce the traction performance curve to fit the power of the load simulation system in the laboratory. The study then simulates and authenticates the system control following the method above. The authors conclude that the method can accurately and exactly simulate the traction motor load.
