摘要
简述了直线电机系统的轨道结构特点。根据国外直线电机地铁的试验测试数据,提出了其环境评价振源强度的取值问题。针对直线电机系统对轨道的特殊要求,通过对碎石道床、浮置板轨道、弹性长轨枕整体道床在直线电机系统中的减振比较分析,认为弹性长轨枕整体道床能满足直线电机系统对轨道的减振降噪要求。
The structure of track in linear induction motor （LIM） system has its unique features. According to the tested data of overseas LIM metro system, this paper discusses the value sampling of the vibration source＇ s strength, and the special request of LIM system for the track, argues that the elastic crossing tie embedded track bed shall meet the needs of LIM for vibration damping track, and the corresponding research shall be based on serious comparative analysis.
