摘要: 基于对机车异步牵引电机谐波转矩的分析,导出了谐波转矩的计算公式,建立了机车动力学计算模型,并对机车直线和曲线运行时的动力学参数进行了计算.计算结果表明,异步牵引电机谐波转矩对驱动装置的动力学性能和机车的纵向动力学性能影响较明显,而对机车整体动力学性能的影响较小.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.
