摘要
对沙漏簧在地铁、轻轨车辆上使用的优点做了介绍。分析了沙漏簧的结构特点和垂向刚度的非线性特性。采用试验测试和有限元分析相结合的方法对沙漏簧的垂向失稳特性进行了探讨。
With an introduction of the advantage of the hourglass-spring which is applied in urban rail vehicles,this paper analyses the structural characteristics of the hourglass-spring and it＇s non-linearity feature of the vertical stiffness curve.The characteristics of the vertical instability were discussed by experimental tests and finite element analysis.
