摘　　要：文章介绍了线性轴承在磁浮车辆悬浮架上的应用优势与结构组成,并以某型磁浮车辆为例,阐述了满足曲线通过能力的线性轴承的选型方法,采用JB/T 7175系列标准对线性轴承的基本额定静、动载荷及使用寿命进行分析评估。经试验验证,该型线性轴承的使用寿命和防锈能力均满足标准要求。This paper presents the application advantages and structural composition of linear bearings on the suspension frame of maglev vehicle. Taking a certain type of maglev vehicle as an example, it expounds the selection method of linear bearings that meet the curve passing ability. Using standard JB/T 7175, it analyzes and evaluates the basic rated static load, basic rated dynamic load and service life of linear bearings. The service life and rust prevention ability of the linear bearing meet the standard requirements by test verification.
