摘要
针对3个钢制车轮在弯曲疲劳和径向疲劳试验过程中提前失效的问题,利用断口扫描、能谱面扫描、显微组织和低倍组织等试验分析了材料和加工工艺对车轮疲劳性能的影响。结果表明,材料中小尺寸夹杂物聚集,轮辋和轮辐合成焊接、轮辋闪光对焊的参数不当均会导致车轮疲劳性能的削弱。
Aiming to three cases of premature failure of steel wheels during bending fatigue and radial fatigue tests,this paper analyzes the influence of materials processing technology on wheel fatigue performance using fracture scanning,energy spectrum surface scanning,microstructure,and low magnification experiments.The shows that the aggregation of small-sized inclusions in materials,improper parameters in the synthesis welding of wheel rims and spokes,and incorrect parameters for flash welding of wheel rims all lead to the weakening of wheel fatigue performance.
