摘　　要：为了探究适合轨道车辆的ISD悬挂结构,提出了一种滚珠丝杠式电涡流阻尼减振器,利用洛伦兹公式建立了其数学模型。从结构和磁路设计出发,确定了电涡流阻尼产生单元的四个关键设计参数和三个特征参数,设计了四因素四水平的正交试验并进行了极差分析和趋势分析。结果表明:对临界速度、初始阻尼系数和最大阻尼力等特征参数的影响显著性排序依次为导体厚度、磁体中心角、气隙大小和外缸筒厚度;对于不同特征参数,各因素影响显著性差异很大。据此建立了基于影响显著性的电涡流阻尼产生单元的设计方法及原则,为实现参数化设计打下了坚实的基础。In order to explore the ISD suspension structure for rail vehicles,an eddy current damper is proposed based on the ball screw,and its mathematical model is established from the Lorentz formula.Four key design parameters and three characteristic parameters of the eddy current damping unit were determined based on the magnetic circuit structure.On this basis,orthogonal experiments with four factors and four levels were designed,and range analysis and trend analysis were conducted.The results show that conductor thickness,magnet canter-angle,air gap size and outer cylinder thickness have the same gradually diminishing influence on the characteristic parameters such as critical speed,initial damping coefficient and maximum damping force.However,the significance of each factor is very different for different characteristic parameters.A design method and principle for the eddy current damping unit are established based on the significance of influence,laying a solid foundation for the parametric design.
