摘　　要：由于直线电机地铁车辆电机悬挂具有特殊的结构形式,因此其振动特性也具有不同于传统电机悬挂车辆的特点。为了研究直线电机地铁车辆的振动特性,从结构上分析直线电机的定位方式,并对其振动特性进行分析,然后分别研究在未计直线电机法向力的情况下直线电机悬挂结构对转向架振动特性、轮轨相互作用及轮轨激励传递特性的影响。研究结果表明:直线电机的垂向振动和横向振动存在一定程度的耦合,且直线电机定位结构对转向架的振动和轮轨关系都具有极大的影响。Since the suspension system of linear motors of Metro vehicles has a special structure form, its vibrationcharacteristics are different from those of the traditional motor suspension structures. In this article, the method for linearmotor’s positioning was introduced, and the vibration characteristics of the suspension system were analyzed. Then, theinfluence of the suspension structure on the bogie’s vibration characteristics and wheel- rail interaction was studied. Theresult showed that the vertical vibration and the lateral vibration of the linear motor are coupled mutually, and the positioningstructure of the linear motors has a great impact on the bogie’s vibration and wheel-rail interaction.
