| 摘 要： | 运用有限元技术,选取磨耗到限的车轮和最恶劣的运用工况,对DF系列机车轮对加装扣环后的强度进行了分析计算,结果表明,机车轮对在加装扣环后各关键点的应力均低于屈服极限,各关键点的疲劳安全系数均大于1,证明了轮对加装扣环后对其强度的影响是有限的,安全系数是有保障的,能够满足使用要求。

| Abstract: | Selecting the wheel of wearing to limit and the worst estate of running , the intensity of the wheelset is calculated by using finite element method. The result indicates that the stress of every key-point of the locomotive wheelset is lower than its bend-limit, and the fatigue-safety factor of every key-point is bigger than 1. It is proved that the influence to its intensity is smaller and the safety factor is assuring after fixing circlet on the locomotive wheelset . |
