摘　　要：建立了中低速磁悬浮列车用混合悬浮电磁铁的Maxwell二维温度场仿真分析模型,对其温度场特性进行了分析,并与传统纯电励磁结构的悬浮电磁铁进行了比较。针对工程实际样车用混合悬浮电磁铁分析指出,电磁铁最高温度位于励磁线圈中心处,铁心轭部温度与励磁线圈温度基本相同。采用混合悬浮电磁铁结构不仅大大降低了悬浮损耗,减少了列车运行能耗,而且改善了悬浮电磁铁的温度特性。2D Maxwell temperature field simulation model of the mixing suspension electromagnet for mid-low speed maglev train was established.The temperature characteristics were analyzed and the corresponding calculation results were compared with the tradition structure.The simulation analysis for one engineering vehicle showed that the highest temperature point of the mixing electromagnet lied at the exciting winding center and the temperature of the iron core yoke was near the same as the exciting winding.The suspension energy loss and energy consumption in train running were greatly reduced and the temperature characteristics were also improved when the mixing electromagnet was used.
