为探究高速列车车轴内部与外部缺陷耦合作用对车轴疲劳裂纹萌生的影响,基于晶体塑性理论,在介观尺度上建立车轴多晶体有限元模型。对车轴试样进行拉伸与冲击试验,结合有限元仿真,对车轴内外缺陷附近应力场及结构变形进行分析,探究内外部缺陷耦合对车轴疲劳裂纹萌生的影响;并基于应力分布和塑性应变能密度分布的特点,对裂纹萌生位置进行预测。结果表明,当内部缺陷越靠近表面外部缺陷时,两缺陷间的相互作用越大,对裂纹萌生起到促进作用。当内部夹杂物缺陷处在模型中心部位时,两缺陷间的相互作用最小,并且外部缺陷是导致裂纹萌生的主要因素。
In order to study the effect of coupling between inner and outer defects of high⁃speed train axle on fatigue crack initiation, a multi⁃crystal finite element model of high⁃speed train axle was established on mesoscopic scale based on crystal plasticity theory The stress field and structural deformation around the inner and outer defects of axle were analyzed by tensile and impact tests, and the effect of inner and outer defects coupling on fatigue crack initiation was investigated Based on the characteristics of stress distribution and plastic strain energy density distribution, the crack initiation location was predicted. The results show that the interaction between two defects was stronger when the inner defect was closer to the outer defect, and the crack initiation was promoted when the inner inclusion defect was at the center of the model, the interaction between the two defects was minimal, and the external defects were the main factors leading to crack initiation.
