In this paper, the fatigue behavior of railway wheel specimens subjected to cyclic loading have been investigated via experimental tests and numerical analysis. The material behaviour of the wheel specimen has been modelled by means of the Ramberg‐Osgood equation. The non‐linear Kujawski‐Ellyin (KE) model has been adopted for the fatigue crack propagation under small‐scale yielding (SSY) conditions. The formulation of the rigid-insert crack closure (RICC) model has been applied to a specimen of railway wheel that has the same conditions as a real instance. The results indicate that the fatigue life of specimens decreases with any increase in load level.

在本文中，通过实验测试和数值分析研究了铁路车轮试样在循环载荷下的疲劳行为。车轮试样的材料行为已通过 Ramberg-Osgood 方程建模。非线性 Kujawski-Ellyin (KE) 模型已被用于小规模屈服 (SSY) 条件下的疲劳裂纹扩展。刚性插入裂纹闭合 (RICC) 模型的公式已应用于与真实实例具有相同条件的铁路车轮试样。结果表明，试样的疲劳寿命随着载荷水平的增加而降低。
