【Abstract】 Through analyzing the harmonic torques of asynchronous traction motors of a locomotive,the formulas of calculating the harmonic torques were derived,and a dynamic model for locomotives was established.The tangent dynamics and curve negotiating dynamics of locomotives were simulated.The simulated results show that the harmonic torques affect motor dynamics and locomotive longitudinal dynamics significantly,but they have little effect on the other locomotive dynamic behaviors.更多还原
