摘要
提出了根据电传动系统组成及电传动系统各环节能量传递特点分别建立评价指标的牵引电动机评价方法。电传动系统主要包括电动机、柴电机组、轮边减速器和电传动系统集成系统。从电机本体及控制性能、电传动系统配合指标和具体循环行驶工况3个层面精简列出9个评价指标,以电传动试验和计算机仿真平台为评价测试手段,针对各类牵引电机建立了综合性能评价体系,采用粗糙集理论的评价方法展开具体分析。实验及测评结果表明,该评价模型能够对各类型牵引电动机进行较为准确的评价,且准确率明显高于主观赋权分析法,验证了该评价方法的完整性和实用性,同时,永磁同步电机综合评价指数高,具有较高的研究价值。
The traction motor evaluation method was presented depending on the electric transmission energy transfer characteristics and different source of supply, including motor manufactures, diesel turbine manufacturers, wheel side re- ducer manufacturers and electric drive system integrated manufacturers. 9 evaluations were proposed in 3 levels from the motor body and control performance, electric drive system coordinate index, driving conditions and specific cycle. Motor performance evaluation system was published by the means of electric transmission tests and computer simulation platform, using rough set theory. Experimental results show that the model can accurately evaluate all kinds of traction motors, and its evaluation accuracy is better than the subjective weighting analysis, verifying the integrity and usefulness of this valuation method. And the comprehensive evalution index of permanent magnet synchronous motors is high, it has important research value.
