摘　　要：统计了上海铁路局机车整体辗钢车轮上线运行以来所发生的故障现象,分析了故障产生的原因及危害。针对威胁行车安全的危害性缺陷——辋裂和剥离,指出当前探伤工艺的局限性。介绍了辋裂缺陷的超声波检测方法,以弥补原检测手段的不足,有效地检出缺陷,保障行车安全。The defects caused by the integral rolled-steel wheel were statistical. The cause and damage were analyzed for the defects. The present testing procedure was very hardly effective to test the circumferential crack and stripping defect. The effective testing method for such crack was introduced, which had great value to assure the locomotive safty.
