| 摘 要： | 为了对高速轮对踏面外形进行优化改进,提出了一种基于轮径差相对于轮对横移量的函数为设计目标来反推铁道车辆车轮踏面外形的优化方法,并研制了相应的计算程序.对LMa,S1002G和XP55型踏面的优化结果表明,优化后的轮对踏面外形具有良好的几何接触特性和动态特性.提出了高速踏面选型的优化流程.

| Abstract: | A target-oriented method for the design of railway wheel profiles is presented. The target chosen is the rolling radii difference function which plays an important role in the dynamics of railway vehicles especially for high speed performances. A computer program based on this method has also been developed and is validated by way of examples in which wheel profiles LMa, S1002G and XP55 are investigated.An optimization process for selecting a suitable profile for high speed vehicle has been put forward. |
